Storage Tank Hot Water Heaters

This guide will focus mainly on the traditional storage tank water heater, although it will cover tankless heaters too. See our Tankless Buyer Guide for a more in-depth overview of those systems. The storage tank water heater is the most common type of water heater in the world today, with particular popularity in the U.S. and Canada.

How Do They Work?

Traditional storage tank heaters consist of a vessel or container, usually found in the basement of a home near where the furnace is kept, and it typically holds water ranging between 75 to 400 litres.

The water heater will heat the entire content of water that’s being held in its container ready for use when called upon. They tend to be efficient thanks to the fact that they can utilize energy at a fairly slow rate as the heat is stored for later use.

However, a disadvantage to water heaters of this type is that during periods of heavy water usage, the heated supply of water in the tank can be used up. This can cause a period of delay before hot water is flowing again!

Storage tank heaters can be powered by a number of different types of fuel. Below, we have compared a number of different types of fuel for water heaters, so you can see what is best for you.

Gas

Gas water heaters are great if there’s a natural gas pipeline available to use for your home. Gas water heaters tend to be cheaper to run than electric heaters and other types, as well as being able to heat the water at a faster pace. They also benefit from the fact that they’re easier to repair than electric water heaters.

However, gas water heaters incur a more difficult installation process due to the need for ventilation due to the emissions that are released. They also tend to have a lower lifespan than an electric heater and can cost more upfront.

Electric

An advantage to electric water heaters is that they’re easier to install thanks to not needing any ventilation. They also do not run on “fuel” like gas or propane which makes them very efficient. Thanks to running on electricity, they tend to be better for the environment because they produce fewer emissions and also manage a longer service life than gas heaters.

Nevertheless, there are some downsides to electric water heaters. Electric water heaters often have a slower flow rate than a gas water heater, and you can be at risk of a short circuit or blown fuse. They also tend to be quite difficult to repair due to the electrical component.

Gas vs Electric Water Heaters

Price: Gas water heaters are usually more expensive to buy and less expensive to operate. Electric water heaters have a lower upfront cost but are usually more expensive to operate.

Efficiency: Electric water heaters are more efficient than gas ones.

Installation: Gas water heaters are more difficult to install because they need to be vented, and they also require more space because of the venting.

Fuel availability: Gas water heaters run on natural gas, but not everywhere in Canada has a direct hookup available. If you don’t, then you might be able to convert the water heater to run on propane, but then you must have the propane delivered and stored on-site.

Heating time and demand: Gas water heaters heat water faster than electric ones and are typically better suited for homes with higher hot water demands.

Safety: Electric water heaters are safer because there’s no risk of a gas leak, explosion, or carbon monoxide poisoning.

Environment: As long as your electricity comes from a renewable source and not fossil fuels, electric water heaters are better for the planet and have a lower carbon footprint.

Lifespan: Electric heaters often have longer lifespans of 10 to 15 years compared to eight to 12 years with gas water heaters.

Tankless Water Heaters vs Traditional Tank Hot Water Heaters

Although this guide focuses mainly on traditional tank-style water heaters, it’s worth mentioning tankless water heaters, which are gaining in popularity.

A tankless vs tank hot water heater can be more efficient because it only heats the water when needed and can provide nearly limitless hot water. We’ve put together the list below to help you weigh up the pros and cons of a tankless water heater.

Tankless Water Heater Pros

• They save money by not using energy throughout the day when no hot water is being called for
• Because water is heated on demand, it can be a virtually limitless flow
• They are smaller and more space efficient than tank water heaters
• Because of their smaller nature, they can be fitted closer to the areas of your home where you actually need the water, unlike tank heaters which are usually in the basement

Tankless Water Heater Cons

• It can be very expensive to switch from a tank water heater to a tankless heater. This is because you’ll generally have to retrofit your plumbing and possibly even your electrical system
• Economically, due to the expensive switch, they only really make sense if you’re building a brand-new home or adding a new space to an existing one.
• If you have an electric tankless heater and there’s a power outage, you’re left with no hot water. This is unlike an electric traditional tank water heater, as you’re still left with the pre-heated water in the tank to ration until the power is restored

Traditional Tank Water Heater Pros

• They have a lower initial cost in terms of purchase and installation
• Most contractors are familiar with tank water heaters, so it should be straightforward and less expensive for installation and repairs
• You get a steady supply of hot water, which is ideal for households with simultaneous water usage
• Doesn’t require a high flow rate to function properly
• Equipment is reliable and doesn’t require a lot of maintenance
• Available in many sizes to suit different households

Traditional Tank Water Heater Cons

• Once the stored hot water runs out, you have to wait for the tank to refill and reheat
• They’re less efficient because they’re always keeping a large tank of water hot, and even with proper insulation there will be heat loss
• Shorter lifespan of eight to 12 years compared to tankless models, which can last 15 to 25 years
• The tank takes up a lot of space, which may be an issue in smaller homes
• There’s a potential for leaks and flooding, especially as the equipment ages

Best Features To Look Out For

Drain Valves

Drain valves are not an expensive part of the water heater in themselves, but they’re crucial to its operation. Brass drain valves may cost more than plastic drain valves, but they’re far more reliable and effective. We suggest going for a water heater with brass drain valves where possible!

Glass Lining

Some water heaters include a glass-lined tank. The glass-lined tank helps to reduce corrosion on the interior of the tank, helping to prolong a unit’s service life and prevent maintenance issues that can be caused by corroded parts.

User-Interface

Premium water heaters include technology such as digital displays. These digital displays can show you exactly how the water heater is performing, can help you monitor your purchase and customize how it runs, and some even include a vacation mode to ensure you save money while you’re away.

Best Water Heater Brands

A.O. SMITH / GSW / JOHN WOOD

These water heater brands offer high-efficiency gas/propane, electric tank, hybrid heat pump, tankless, and solar-powered water heaters. With over 600 different models of water heaters available, there’s an option for nearly any home. Many are also ENERGY STAR certified.

These brands are all connected, for example. A.O. Smith operates under John Wood in Canada, and they’re currently the largest manufacturer and marketer of water heaters in North America. Their ProLine & Proline Master Electric models all exceed NRCan energy efficiency standards and meet national energy efficiency requirements.

They also have over 80 years’ experience manufacturing the patented glass-lined water heater – which helps reduce erosion on the interior of the tank. For example, John Wood’s patented Blue Diamond glass coating is zircon-enriched, helping provide a tougher, water-resistant lining.

The price of these units is dependent on how efficient the heater is, your home details and how much additional technology they include. It’s best to ask a wholesaler/contractor to get a better idea of pricing specific to your circumstances!

Rheem and Ruud

Rheem and Ruud manufacture gas-fired tank storage and tankless water heaters, as well as a number of other water heating items and equipment.

Higher-end models have impressive efficiency ratings, and select models are also ENERGY STAR rated. Many of these models also come with high-tech user-interface tools to help provide detailed system diagnostics and control.

There are also natural gas and propane burning models that feature eco-friendly burners with low NOx designs, helping the water heater to achieve its high-efficiency levels as well as helping the environment!

It’s worth considering the models that feature Rheem’s Guardian System air/fuel shut-off device which disables the heater in the presence of flammable vapour accumulation, increasing safety. These units are also low maintenance and require no filter.

Whirlpool

Whirlpool is one of the world’s largest home appliance manufacturers, and chances are something in your home has been made under the Whirlpool Corporation.

Whirlpool water heaters include some impressive features, such as self-cleaning technology, and numerous additional safety features. Some of these safety features include the FLAME LOCK Safety System which reduces the risk of accidental fires, 6th Sense technology which uses microprocessor-controlled Honeywell gas valves for tighter temperature control, fewer moving parts and self-diagnostic technology.

Whirlpool’s heaters also use environmentally friendly non-CC polyurethane foam insulation to reduce heat loss, and their models are certified up to an altitude of 10,100ft, great for those living at higher altitudes.

Water Heater Warranties

Depending on what model of water heater you choose, and from which manufacturer, warranties can vary. On average though, water heaters generally come with a warranty period of three to twelve years. Unsurprisingly, premium units tend to have longer warranty periods.

Installation: Setting Up Your New Water Heater

Unless you’re a certified HVAC professional yourself, we strongly recommended having an experienced HVAC company or contractor fit your water heater for you. Mistakes can be extremely costly and do damage to your home.

Depending on what water heater you’re having fitted, the installation time can vary. If you’re moving to a tankless water heater, expect it to be a larger job as often plumbing will need to be changed, and additional professionals may be required for the job.

If, however, you’re upgrading to a tank water heater of a similar type, chances are it won’t take long. Nevertheless, when choosing an HVAC service provider to install your brand-new unit, make sure to look out for their reviews, and don’t be afraid to ask about their certification. Choosing the wrong professional can be costly.

Rent or Buy: The Water Heater Dilemma

There are pros and cons to renting a water heater versus buying one, and vice versa. It really comes down to your specific situation.

Renting a water heater has lower upfront costs, maintenance is covered, and there won’t be any unexpected expenses. However, you will pay a lot more over time compared to if you buy.

Conversely, buying a water heater has a higher upfront cost but lower lifetime cost. You are responsible for repairs and maintenance, but you’ll still pay less in the end. It can also help increase your home value.

In general, if you don’t have plans to move and have it in your budget, you’re better off buying a water heater than renting. Many local HVAC companies have financing plans that can help you pay it off over time rather than in one lump sum up front.

Water Heater Costs and Average Prices

On average, storage tank water heater prices are between $1,000 – $1,300 including installation, but this depends on where in the country you live, what manufacturer and what tier of unit you decide to go for.

Tankless water heaters, on the other hand, tend to be more expensive. This is because they can mean a whole new plumbing system for your home, and that’s why, for many, a tankless water heater is best if you’re building a new home or at least an extension to your home.

On average, a tankless water heater costs around $2,000 – $4,500 including installation.

Water Heater Installation Cost

For a tankless water heater, installation costs can range from $800 to $3,000 for materials and several hours of labour.

By contrast, tankless water heater installation costs are far lower, typically ranging from $500 to $1,500 for materials and labour.

Water Heater Rental Cost

If it’s not in your budget to cover the full cost of a water heater, renting may be an option.

The average cost to rent a water heater in Canada is between $15 and $60 per month. Rental rates vary by province and depend on things like tank versus tankless, capacity, gas versus electric, and installation fees.

Financing Your Water Heater

When you put the cost of a brand-new water heater and the cost of installation together, you can be looking at a sizeable up-front cost. However, in most cases, there are financing options available to you.

Financing allows you to pay back the cost of a water heater over time, usually a number of years, with bi-weekly or monthly payments. Be wary of interest rates though, as high-interest rates can mean you pay back far more than the cost of your heater and installation by the end of your repayment period.

However, many manufacturers and HVAC companies have special promotions at certain times of the year advertising various models or services, financed, at a lower interest rate. If you’re able to pick up the model or service you’re looking for during a promotional period, you could save a lot of money!

Exploring Rebates and Incentives for Energy-Efficient Water Heaters

In Canada, 17.2% of the energy used in the average home goes toward water heating, making it the second highest contributor to energy bills behind space heating.

Investing in energy-efficient HVAC equipment is always worthwhile because it’s better for the planet and better for your wallet in the long run. Although you’ll pay more up front, you’ll pay less over time in energy bills.

There are often rebates available to help cover the additional cost of energy-efficient equipment. Organizations that offer rebates include governments, banks, utility companies, energy organizations, and HVAC companies and manufacturers.

Check out the updated list to see what water heater rebates are available in your area.

Assessing Space Requirements: Sizing Your Water Heater

Choosing the right size water heater for your home depends on the type of water heater, how many bathrooms and appliances, number of people, fuel type, and hot water usage patterns.

To determine what size storage tank water heater you need, you must consider two key figures: A) How much water you use at the busiest time of day; B) the first hour rating.

During the busiest time of day, think about how many people are showering, doing laundry, washing dishes, running the dishwasher, or putting other demands on the water heater. Calculate how much hot water your household uses during peak demand. Here are some general numbers to help you calculate:

When you’re shopping for water heaters, keep that number in mind and match it with a system that has a similar first hour rating (FHR). The FHR is the amount of hot water, in gallons, a unit can supply in the first hour of operation when starting with a full tank.

To recap: You need a water heater with a first hour rating that can handle your home’s hot water demands during peak usage.

New Water Heater Pro Tips

Insulate

One of the downsides to tank water heaters is that once the water is heated, it slowly cools over time causing the need for more energy to heat the content back up. To slow the rate that water cools, consider insulating the pipes around the heater.

So, if you’re looking to save money on your monthly water heating bill, consider insulating your hot (and cold) water pipes that are within 2 to 3 meters of your water heater. This is one of the most effective improvements you can make to your existing or new storage tank water heater!

Check Your Water Heater Settings

Most water heaters allow you to set the maximum temperature the water in your home can be heated to. If you’re worried about leaving your tap running on maximum heat and then sticking your hand under it, then it may be worth turning down the maximum heat on your water heater.

A lower maximum heat is safer, and this is particularly the case if you’ve got children in your house. But also, by turning down the maximum temperature your water heater can reach, you can save money too! A lower maximum temperature means less energy wasted as you’re heating your water to the temperature you want from the start.

However, be wary of the fact that setting your water heating temperature too low can lead to a growth in bacteria in your water system, as the hot water can help prevent things such as legionnaires’ disease. If in doubt, seek out a professional opinion who can evaluate your home and needs personally.

Your New Water Heater

Buying a new hot water heater is a substantial investment for your home. Whether you’re replacing your old unit or building a brand-new property, we hope this guide has helped you make an informed choice. Remember, take your time when purchasing a new heater – deals are always available, and it’s a good idea to shop around before making a purchase!

Maintenance Tips for Prolonging Water Heater Lifespan

A storage tank gas water heater has an average lifespan of eight to 12 years, and regular maintenance will help give it the longest life possible. Regular maintenance for a water heater includes:

• Flushing the tank annually
• Checking the anode rod for corrosion every couple of years
• Testing the temperature and pressure relief valve annually
• Checking regularly for leaks and corrosion
• Inspecting the gas connections and burner
• Scheduling an inspection with a professional HVAC technician every few years

Addressing Hard Water Issues: Impact on Water Heater Performance

Hard water has high concentrations of minerals like calcium and magnesium. The minerals can build up in the system and significantly impact a water heater’s efficiency, lifespan, and performance in the form of:

• Reduced water pressure
• Increased maintenance
• Longer heat-up time
• Lower efficiency
• Strange noises
• Blockages
• Shorter lifespan

Prevent damage and reduced performance from hard water by:

• Taking care of regular maintenance
• Flushing the tank every six months
• Lowering the temperature to 120°F / 49°C
• Installing a water softener

And when it’s time to replace your water heater, look for one with corrosion-resistant features.

Exploring Hybrid Water Heating Solutions

A hybrid water heater is a heat pump water heater that extracts heat from the air and transfers it to the water in the tank to provide domestic hot water.

One of the main benefits of these systems is their efficiency. Heat pump water heaters with ENERGY STAR® certification use up to 70% less energy compared to standard electrical water heaters.

Heat pump water heaters are also environmentally friendly, have a long lifespan, and can handle high demand. And some hybrid water heaters can switch between heat pump heating and regular electrical heating during periods of high demand.

However, they are more expensive than conventional water heaters, require more space for installation, and typically work best in mild/warm climates.

Water Heater Frequently Asked Questions

Did you know that hot water heating systems can account for nearly 19% of a home’s average energy use?

Obviously, there are variations based on climate and geographical location, but the crux of the matter is, the amount of energy you’re consuming to heat your home’s water is significant.

Are you using too much energy? And how do we even begin to understand the impact different systems have on your home and energy usage?

We’re here to give you a quick guide in understanding your home’s water heating systems. Keep reading to find out how to choose the best system for your lifestyle and budget.

How Hot Water Heating Systems Work

There are several ways we heat water in the modern age, as well as several different energy sources used in the process. Most solutions are electric, which is ideal because it paves the way for clean and efficient energy usage. Natural gas water heaters are also very common in many parts of Canada, which can provide effective and budget-friendly hot water heating options.

Let’s break down some of the primary hot water heating systems used today.

Storage Water Heaters

Many systems use storage units to house their hot water. They’re typically less expensive and have low operational costs, but they can consume more energy than strictly necessary. 

Because they’re working to keep your water hot, even when it’s not being used, you’re likely paying for energy that is just being wasted. Insulation can help with this, as can installing a system that works on a timer, like a smart thermostat.

That being said, most modern units do offer very good insulation already built-in, and you can try turning down the temperature setting a few degrees as well.

Tankless Water Heaters

While tankless heaters cost more to purchase and install, they’re between 8% to 34% more energy-efficient than storage water heaters. This obviously depends on the amount of water you use, but a swap to a tankless system can save you $100 or more every year.

The primary benefit is that a tankless system can heat water instantly. When you turn on your hot water, cold water first runs through the system. This passes through a heat exchanger before reaching you, where it is heated via a gas burner or electric element.

Gas-fired models tend to work best as they can typically heat water more quickly.

Combi Boilers and Hydronic Heating Systems

A combi boiler is a two-fold system. It is also a popular option for homes that are heated with radiators. It is a simple but efficient system that supplies hot water directly to your faucets and radiators. 

A combi boiler is beneficial in that a single unit can both heat your home and provide hot water for everyday use. Because of this, they can be both energy and financially efficient.

In a hydronic system, once the water has been used, it is returned to the boiler to be reheated via a recirculation system. Unlike other heating systems, combi boilers and hydronic heating systems tend to produce less dust than forced-air systems, making them ideal for allergy sufferers.

Choosing the Right System for You

Before upgrading or buying a hot water heating system, you need to consider some important factors. Depending on your home, where you live, and the lifestyle you lead, you could have very different needs compared to someone else.

Size

In order to accurately determine the kind of water heater you need, you must determine its flow rate. For example, is it for the entire house or just a bathroom?

You can list the number of hot water outlets you have like sinks and showers and add up their flow rates. We can calculate the flow rate by looking at how many gallons per minute each uses. This is the rate you’ll want to find your water heater to supply. 

Fuel Type

Consider the fuel or energy you’ll need to use and take into account its availability. Fuel affects more than just operational costs. It has an impact on the size of your unit and its energy efficiency.

There are currently six types of fuel used predominantly throughout the USA and Canada. These are: 

• Electricity
• Fuel oil
• Geothermal energy
• Natural gas
• Propane

Some regions will have more of one and it may be difficult to source others in different areas. Check what’s available locally and let that guide your decision-making.

Energy Efficiency

Let’s keep this simple. We calculate the energy factor (EF) based on the amount of fuel consumed to produce hot water over the course of a day. You need to consider recovery efficiency, standby losses, and cycling losses, which are all natural parts of working with anything that requires energy. 

How much energy does it use to heat the water you just used? Do you lose much when the system is in a passive state, as you do with a storage heater? And when water is cycling through your home, is there a loss of energy?

You don’t have to be an expert here, as a knowledgeable consultant will be able to help you with all your questions.

What Is Worth the Cost?

This is a bit of an open-ended question, as it depends on where you live, what manufacturer you choose to go for, and the unit you want. 

The average storage-tank water heater can cost between $1,000 and $1,500. A tankless water is more expensive initially but cheaper to operate. Expect it to set you back around $2,000–$4,500, including installation, depending on the model.

If you’re looking for an upgrade, consider the long-term implications and how much money it could save you. Some of the most efficient units, like an ENERGY STAR® water heater, could save you up to $300 per year.

A large investment now could mean more flexibility and comfort later. What we can tell you right now is that investing in an energy-smart water heater is one of the best decisions you can make for your home (and your wallet).

Finding a Solution to Suit

Whether you opt for a traditional tank hot water heater or a tankless water heater, or a combi-boiler if you have a hydronic heating system, there are energy-efficient models available.

Our local HVAC contractor partners can help you assess your needs and compare solutions. Compare quotes today!

So you’ve upgraded from a tank-type water heater and moved to a tankless one. This should be a game changing experience: finally, all the hot water you want, without needing to constantly heat it (and waste so much money maintaining a tank of hot water).

But as the water is flowing, you may find that the water heater you installed isn’t exactly what you hoped it would be. Yes, it’s true: tankless water heaters sometimes need repair work. Fortunately, a lot of the problems are easy to solve on your own without needing to call a repair person. Here are some of the biggest problems that we see regarding tankless water heater repair and plumbing problems.

Note that this article is for informational purposes only, and you should consult a professional before attempting any repairs.

Why is my tankless water heater not heating my water?

Cold water. This is by far the number one problem that comes up in regards to tankless hot water heaters (and tank hot water heaters, too). You’re just not getting all the hot water out of them that you want to.

The first thing know is that you will get only cold water for a short time before the hot water reaches you. The pipe between the water heater and you is filled with cold water when you turn on the water heater, and it takes a short tie before the hot water gets to you.

Otherwise, there could be several problems at play here. The first, and the most common, is that demand is running too high for supply. If you’ve got three people in the house taking showers, and the dishwasher is running and the clothes washer is running, then odds are good that your water heater just can’t keep up.

The Solution: There are a few solutions here, and they boil down to supply and demand. Either you need to make sure that not everyone is using the hot water heater at the same time, or you need to upgrade. You can upgrade by switching to a tankless water heater with a higher capacity, or you could add a second unit, either in parallel with the main one or elsewhere, to serve one or more of the places you use hot water.

When it comes to tankless water heater installation, adding a parallel second unit isn’t an elaborate fix and can be done in just a few hours by the technician. (Or you could get the second tankless water heater installed by yourself if you’re good at plumbing services.)

The best thing is that, while paying for a second water heater may seem like a large cost, it can save you from frustration because you won’t be short on hot water for your shower when you’re rushing to get to work.

Why is my water heater running out of hot water quickly?

Your tankless water heater may start off strong but run out of steam pretty fast. What is the reason for this? The problem may be that the inside of the water heater–yes even tankless water heaters–is full of mineral deposits. This drastically reduces the capacity the water heater can hold and properly heat.

This is especially problematic in places with hard water. The most common minerals to build up in the water heater are magnesium and calcium, which can clog pipes and faucets.

The Solution: There are a couple of solutions for cleaning hard water deposits out of tankless water heaters. The first is to check the filter to see if it’s still in good working condition. If it’s worn out or clogged, then clean or replace the filter–and that may be all you need to do to prevent it from getting worse. But the problem is getting rid of the deposits that are already inside.

Fortunately, there are products that you can buy that will descale your water heater. Whether you know if you have hard water deposits or not, it’s a safe idea to run these descaler kits through the water heater at least once a year. You may want have your tankless date heater professionally serviced on a regular basis to keep it in top operating condition.

And finally, maybe think about investing in a water softener for your system. It can prevent a lot of headaches.

Why am I getting an error on my tankless hot water heater?

There are several warnings that you can get on your tankless unit’s readout, but one that comes up frequently is that your air supply is blocked. This could either mean that you’re having trouble bringing air into the water heater, to allow for the combustion of the gas tankless water heater, or you’re having trouble venting the exhaust. Obviously, both are going to be bad.

The Solution: The first step is to inspect all of your vent pipes. Look for holes, disconnects, or blockages. If they’re blocked, evaluate if the blockage is something you can take care of yourself, or if you need a plumber to come in with repair services. For instance, if you can get up on your roof to see whether the top of the vent is blocked, you may be able to. clear an obstruction yourself.

You may find that animals have made their homes in pipes–anything from birds to wasps to mice. (This is your reminder to always make sure your vent pipes are securely covered so no animals can get in in the first place.)

But if the exhaust vent is blocked, you may want a plumber or HVAC professional to correct it; a blocked vent can cause conditions hazardous to your health.

Why is my tankless water heater not igniting?

If your tankless water heater simply isn’t heating up at all, there could be a few problems. The first one is easy: make sure that you’ve paid your gas bill and that gas is still coming to the house. (This can be done by making a call to the gas company, or by checking your furnace or a gas stove to see if they’re working.) If you have an electric water heater, you’ll probably already know that the electricity is on.

The second problem could be that the gas pressure isn’t there, possibly because you have a low propane tank (if you’re not connected to the municipal utility). But there could be more problems that aren’t so easy to diagnose, such as having an ignition system that isn’t properly functional, a regulator that isn’t working properly, or something more technical.

The Solution: If the problem is that your gas bill isn’t paid, or that the propane tank is empty, then you can take care of that fairly easily. If it’s one of the other problems, then you’ll probably need to see a technician about the problem.

Conclusion

All of the problems listed above aren’t hard to fix, but they can require a technician. And different brands sometimes require specialized help. Here are some helpful links for common water heaters:

You might be in the market for a heating unit or looking to upgrade your current heating system. You’ve considered a tankless water heater, but you’re not sure what they are. Maybe you already have a hot water heater and are wondering whether it helps to have a tankless heating unit, too. You’re in the right place to find out all about tankless water heaters, keep reading as we get right into what they are and how they work.

What Is a Tankless Water Heater?

A tankless water heater is a system that heats water only as you need it. When you turn on your tap, the tankless heater quickly heats up enough water to supply hot water to your taps. It then automatically shuts off until you use more. This means that when you’re not using any hot water, there are no energy costs associated with heating it.

In addition to saving energy and money, an on-demand unit also saves space: a single unit replaces both the storage tank and circulation pump of older models. The compact size means it can fit almost anywhere in any home—even in a small closet.

This is ideal because you typically want your tankless water heater installed as close to your faucets as possible to reduce the distance hot water has to run through pipes. This reduces the time you have to wait and lowers water waste.

On-Demand Models Can Be Powered By Either Gas or Electricity

Gas-powered tankless water heaters are more expensive, but they offer similar benefits as an electric tankless model. That being said, natural gas is typically cheaper than electricity in most areas in Canada.

Furthermore, gas tankless water heaters are typically able to heat the water more quickly, since gas burns hotter than electric heating elements.

In contrast, electric tankless models can be more efficient, compact, and in some cases require less maintenance than their gas counterparts.

When to Use a Tankless Water Heater

If you live in a large household or want to reduce your water heating costs, a tankless water heater may be the best option for you.

If your current water heater is a rental, replacing it may be more of a hassle. Furthermore, if you’re planning to move in the next few years, you may not be there long enough to recoup the cost savings, although a tankless water heater is a nice selling point for a home.

Water pressure can be a consideration, especially in more rural areas. If you have a cabin that uses well water, or if low pressure is an issue at home (for example, if there are multiple levels), then tankless systems may not work as well.

Benefits of a Tankless Water Heater

There are several reasons why a tankless water heater might be a better choice than other options. Let’s take a look at just a few of the advantages.

Hot Water On Tap

The biggest advantage of owning a tankless water heater is that you’ll never run out of hot water.

The traditional tank-type system works by storing heated water in a large tank, which fills up over time. When the demand for hot water increases, you have to wait for the tank to fill up again before it can heat more water for you.

With a tankless system, there’s no storage so your family will always have access to warm or even scalding hot showers whenever they need them.

A Tankless Water Heater Is Efficient

Tankless water heaters are more energy-efficient than conventional storage units for several reasons, including the fact that they produce a greater volume of hot water per minute.

This is because tankless models heat water only when it’s needed and don’t store any hot water until there’s an entire tank full.

There’s also less wasted heat in these systems because each unit is individually controlled. This means it only heats what you need at that moment, rather than heating an entire tankful of hot water constantly at whatever temperature it was set to before.

A Tankless Water Heater Can Save Space and Money

A tankless water heater is a good choice if you have limited space, or if your family has many people who use hot water in the home. A tankless water heater can also save you money on your utility bill since it uses less energy to heat water than most storage-type units.

However, installing a tankless unit can be expensive because you may need retrofitting of your gas line and venting system. If you’re not sure whether this type of unit will work for you, consult with an HVAC professional before buying one. 

Long Term Savings

The cost of installation and the initial investment in a tankless water heater can be high, so you’ll want to consider whether or not it makes financial sense for your family before making a purchase.

Due to their higher efficiency and lower operating costs, most homeowners will recoup their investment—and continue saving energy dollars for years after that point.

Does your household use large amounts of hot water on a regular basis? Maybe your children are constantly taking showers or if you have large families who like doing laundry at home.

You might find that one tankless unit isn’t enough to meet all of your hot-water needs. If this is the case for you (or even if you just want peace of mind), consider getting more than one.

Cons of Using a Tankless Water Heater

The biggest con of using a tankless water heater is that they are more expensive to buy, install, and maintain.

You can expect to pay up to $4,500 for the average tankless water heater—including installation costs. It’s also important to note that if you need repair work done after it has been installed, it will cost more than a traditional hot-water heater.

Would You Benefit From a Tankless Water Heater?

Tankless water heaters are a great option for your home or business, and so they are worth researching.

They’re efficient, convenient, and dependable. So the next time you need a new HVAC unit, consider whether tankless is right for you.

If you’re looking for a new water heater, you may be debating between a tankless water heater vs. a tank water heater. These two options broadly encompass most of the available water heaters on the market. If you don’t know the difference between these two options, it can be challenging to choose between them. 

What’s the real difference between the two options? Is a tankless water heater better than a tank one? 

This choice shouldn’t be taken lightly because the average Canadian home uses around 75 litres of hot water daily. You may not often think about your home’s hot water, but it’s a crucial part of daily life for both necessity and comfort. This guide will answer all your questions about the differences (and similarities) between traditional and tankless water heaters, so you can determine which is the best for your family and home. 

 What Is a Tankless Water Heater?

Tankless water heaters are a relatively new invention, with the first systems patented in 1929 and gaining popularity during the 1990s. On the other hand, traditional tank water heater systems were designed in 1889 and quickly became home mainstays starting in the 1920s. But, of course, it wasn’t until the 1940s that water heaters took off, correlating with the rise of electricity in homes.

You may hear tankless units called on-demand water heaters — an apt name because they work by heating water as needed. Anytime you turn on a faucet and require heated water, tankless systems generate as much hot water as you need. As a result, tankless water heaters can theoretically provide an unlimited amount of hot water without ever running out, and they’re surprisingly energy efficient while doing it, too.

 What Is a Tank Hot Water Heater?

A tank hot water heater is the most common and traditional option in Canada and the United States. This is likely what comes to mind when you think of water heaters: a tank (usually fairly large) with several pipes running off it. If your home has one of these water heaters, you’ll probably find it in your basement, but it can occasionally be on the ground level in a water closet (generally for homes without a basement). 

The “tank,” called a vessel or container, typically holds between 75 and 400 litres of water at a time. The water is stored in the vessel and heated all at once to supply your hot showers, dishwashing and laundry needs. The water may be heated using gas, propane, or electricity, depending on the model of water heater. Regardless of how the water is heated, tank water heaters tend to be efficient because they can utilize energy slowly to preserve the heat of the water. 

Pros and Cons of On-Demand Water Heater vs. Tank Water Heater

Both water heater types come with their own sets of pros and cons. Although we’ve provided a more in-depth breakdown below, we’ll briefly discuss these benefits and downsides in a scannable format here.

Tankless Water Heater

The benefits of a tankless water heater include:

• Save money because they don’t consume energy during the day to keep water hot
• Virtually limitless hot water available at any time
• Better choice for tight spaces 
• Can be placed almost anywhere in your home (versus being stored in the basement or water closet)
• Won’t burst during cold fronts
• Virtually zero wait for hot water when you turn on the tap
• Less maintenance is required for the upkeep

The downsides of a tankless water heater are:

• High initial costs for installation 
• Having to retrofit your plumbing (and maybe your electrical system) to install
• Zero hot water reserves if the electricity goes on 

Traditional Water Heater

The benefits of traditional water heaters include:

• Comparatively low installation costs
• Compatible with other systems in the home
• A small hot water reserve during power outages
• Still works during power outages, if powered by gas or propane
• Typically provides a higher flow rate versus tankless options

The downsides of traditional tank water heaters are:

• Higher energy usage because they need to keep the water in their tanks hot when not in use
• Limited amount of hot water available
• Require larger spaces, so they’re typically allocated to the basement
• Can burst during freezing weather
• A short wait before hot water comes through the faucet
• Require regular maintenance and upkeep to work properly

Tankless vs. Tank Water Heaters: An In-Depth Breakdown

Below, you’ll find a more in-depth breakdown of how tankless vs. tank water heaters compare. 

Cost

Regarding initial costs, traditional water heaters are significantly cheaper for a few reasons. For starters, the systems themselves are cheaper. But it’s also important to understand that your home is most likely already designed to integrate with a traditional system, meaning there aren’t any additional installation costs. 

On the other hand, tankless water systems often require you to retrofit your plumbing, and you may need some electrical work before installation, too. This can significantly drive up the initial costs of a tankless system, making it a poor choice if you’re a Canadian homeowner on a tight budget.

Long-term costs tell a different story. Tankless systems require less maintenance, and they can last up to twice as long as traditional systems. Paired with their energy efficiency, tankless systems are less expensive over their total lifetime compared to tank water heaters. 

 Energy Efficiency

The energy efficiency of either water heater type can vary significantly based on the specific brand and model you choose. However, tankless water heater systems are usually more energy efficient because they don’t need to keep the water heated when not in use. Instead, energy is consumed only when the faucet in your kitchen, bathroom or utility room is turned to the hot setting.

Lifespan

A traditional water heater is estimated to last 10 to 15 years with regular upkeep and maintenance. But tankless systems last an average of 20 years, with some lasting significantly longer. In terms of expected usable lifespan, tankless systems are a clear winner.

Maintenance

Both traditional and tankless hot water systems should have annual maintenance to ensure they’re working properly — even if it’s just a yearly inspection. Generally, the care required for a traditional system is more extensive, making it more expensive.

Space Requirements

Tank water heaters take up a lot of space because the vessel holding the water is large. These tanks also require a safe boundary where nothing else should be placed or installed. On the other hand, tankless systems require significantly less space and can be installed almost anywhere in your home. 

Tank vs. Tankless Water Heater: Which Is Better?

There isn’t a clear one-size-fits-all answer to the tank vs. tankless water heaters debate. Instead, it’s a matter of weighing the pros and cons to determine the best choice for you and your home. For example, if having hot water on demand is the most crucial factor for you, a tankless water heater system is the best choice. If cost is the primary issue, a traditional tank water heater is the clear winner.

Water Heater Frequently Asked Questions

How can I tell if my hot water heater needs to be replaced?

One of the greatest indicators that it’s time to replace your water heater is that it’s reached the end of its estimated usable lifespan. If your water heater has broken, compare the repair and replacement costs. If a repair costs 60% or more of replacement costs, purchasing a new unit is better. Other indicators that it’s time to replace your water heater include rising energy costs, loud noises, weird smells, and lowered efficiency. 

Can you run out of water with a tankless water heater?

You shouldn’t run out of water if you have a tankless water heater system. If you do have a tankless system and run out of hot water, that indicates you need to call an HVAC repair technician.

Will a tankless water heater run up my electric bill?

A tankless water heater should actually lower your electric bill. The reduction in energy costs varies based on numerous factors and may only be a slight (and barely noticeable) amount. However, your electric bill certainly shouldn’t go up after a tankless water heater installation. If it does, you’ll want to schedule an appointment with an HVAC technician to determine the cause behind the rising energy rates.

Hot water isn’t a luxury today. It’s a necessity. We rely on it for cleaning clothing and dishes and for the comfort of a shower or bath. Keeping your hot water heater in good repair is a great way to make sure you don’t wake up to a cold shower, unexpectedly.

You should have your hot water heater checked and maintained by a professional plumber annually to avoid issues and to get the best performance out of your machine. So, what’s included in water heater maintenance? Let’s take a look.

Different Types of Water Heater Maintenance

The first on any list for water heater service is flushing the tank, but not all water heaters have a tank. It’s important to know what type of heater you have before you start looking at maintenance options. For tanked water heaters, sediment build-up is a problem that can lower energy efficiency and cause extra wear and tear on your heater. But, with a tankless water heater, you won’t need to worry about flushing the tank, though you will need to descale the unit periodically. 

Common Water Heater Maintenance Checklist Items

For most water heaters, the items that routinely show up on a hot water tank maintenance checklist include:

• Testing the pressure relief valve
• Draining and flushing the tank
• Testing the heating element

Tankless heaters are exempt from the first two items on the list but will need to have the heating element checked regularly to ensure an endless flow of hot water. 

How Can You Tell If Your Water Heater Needs Maintenance?

In general, water heaters give off signs before maintenance becomes critical. Those signs can vary based on the type of heater you have. If you have a traditional, tanked water heater, you’ll need to know if it’s gas or electric.

Electric Water Heaters

If your electric water heater needs maintenance, it will still produce hot water, but the water may not stay hot for as long as you’re used to. If your shower starts hot but turns cold after a few minutes, that’s a sign that you should call in a plumber to perform further tests and maintenance.

Gas Water Heaters

Gas water heaters tend to last longer than their electric counterparts, but it often means total failure when they have a problem. If a gas water heater needs maintenance, you may not have any hot water. 

Tankless Water Heaters

There are two big signs that indicate your tankless water heater needs service. The first is any strange noises or vibrations that you notice coming from the motor. The second is a total lack of hot water. If either of these happens, it means you need service.

DIY Water Heater Maintenance Tasks

While it’s usually best to call in a plumber to take a look if you notice any problems with your water heater, there are some things you can do yourself. But, if you notice leaks, rust, water discoloration, white powder on your water heater, or strange noises, you’ll want to skip the DIY project and go right for professional plumbing assistance. These can be signs that your heater needs significant repair or replacement.

Flushing a Water Heater

The first step in learning how to flush a water heater is getting the water out. So, here’s a quick guide on how to handle a DIY flush:

• Turn the water off to your heater. If it’s a gas heater, also turn off the gas. You may want to wait a bit before moving on to the next step to allow the water in the tank to cool. 
• Locate the drain outlet on your water heater. Connect a hose (yup, a standard garden hose will fit) and put the open end of the hose in a bucket or floor drain. If you’re using a bucket, make sure you have at least 2 to allow you to empty them as they fill. 
• Allow 20-25 minutes for the water to finish draining.
• Once all of the water is out, turn the water back on and leave the drain open, allowing fresh water to run right through. Let it run for several minutes until the water runs clear. 

It’s best to flush your tank every six months or so, particularly if you have hard water that’s loaded with minerals. 

Adjusting the Temperature

Running out of hot water can sometimes be a result of a lower temperature setting. You can turn your heater up or down, depending on your preferences and usage. 

• Look for a thermostat on the tank. Change the setting if there is one. 
• Electric heaters often have a thermostat hidden behind the insulation. Turn off the power at the breaker and then look for the thermostat. 
• Once you’ve found it, you’ll need to use a screwdriver to slowly turn the control setting. Close the panel, get the power back on, and test the new temperature.
• If the water is too hot or too cold, keep changing the temperature setting until you reach the desired temperature. 

Re-Lighting the Pilot Light

Electric units don’t have a pilot light, with or without a tank, but gas units do. If the pilot light goes out, you can:

• Find the control box and set the knob to the “Pilot” setting. 
• Push the button that ignites the pilot light. If there is no button, use a fireplace lighter or long match held next to the pilot opening to get it lit. 
• Reset the control box and turn it back to the “On” position.

What About Tankless Water Heaters?

If you’re wondering about how to maintain a tankless water heater, it’s pretty straightforward. While there is no tank to flush, the same mineral-filled water can leave deposits inside your tankless system, restricting water flow and lowering efficiency. You’ll need to flush your tankless water heater through the purge port valves and descale the system. This is probably something that is better left to a professional plumber with tools designed specifically for the job.
