Real Navien Boiler Review Data

Customers who have installed Navien boilers in their homes love that they’re quiet systems that run well. They’re energy efficient and can help save on heating costs, have some great features, and are reliable. However, professional installation and regular maintenance by a licensed HVAC technician is critical, otherwise problems and breakdowns can happen more frequently than they should.

Navien Average Boiler Price Range

$4500 – $10,000+ including installation

It’s impossible to give an accurate estimate of the cost to install a new boiler because so many things play into the price. The cost of the boiler alone will vary based on factors like capacity, (which depends on the size of your home), how many zones there are, what special features the boiler has, the efficiency of the unit, and the type of boiler.

All Navien boilers are condensing—even the combi models—and these tend to be the most expensive boiler types because of their efficiency and size.

However, one of the biggest things that will influence the final price of your new boiler is installation, which can range between $1,700 and $3,700 or more. Installation costs can fluctuate based on:

• The make, model, and brand
• Boiler style (such as conventional versus combi)
• Size and capacity of the system
• Number of zones
• Your current heating infrastructure

You can save money on the cost of your boiler by looking for rebates, which are sometimes available from utility companies, local HVAC distributors, the government, and directly from the manufacturer.

ENERGY STAR certified boilers like Navien’s may cost a little more than standard ones, but they also use 10% less energy.  

Navien Boiler Options Reviewed

Condensing Boilers: NFB-H Series and NHB-H Series

The NFB-H Series and NHB-Hseries are high-efficiency condensing boilers with AFUE ratings of 95 percent. Because they’re condensing boilers, they trap and recycle some of the heat that would be lost with a conventional boiler, thereby improving efficiency and heating performance.

These models are also equipped with Navien’s sophisticated burners, which have some of the highest turndown ratios in the industry. They are compact and designed to be easy-to-install, and this could mean lower initial setup costs.

Navien’s Boiler Warranty

Any good Navien boiler review will discuss warranty terms. A good boiler warranty is important for two main reasons: it can save you plenty of money on repair costs, and it can give you an indication of how reliable the system will be.

If a manufacturer only guarantees their product for a couple years, then it might be because they don’t expect it to perform optimally beyond that. By contrast, if a boiler or its major components are warrantied for several years, it’s because the manufacturer expects them to last at least that long.

Navien stands by all their products with a good warranty, but the specific terms change a little depending on the series:

NAVIEN: ABOUT THE COMPANY

They run well and don’t experience too many maintenance issues, but it’s still important to have your boiler maintained annually. What’s more, people like that Viessmann has good customer service and tech support and that parts are readily available.

Viessmann Average Boiler Price Range

$5,000 – $8,000+ including installation

Without knowing all the specifics, you can’t get a really good idea of what it might cost to buy and install a new Viessmann boiler. So many things can affect the price, including:

• Boiler size and output
• Where you live
• Number of zones
• Special features and AFUE ratings
• The specific type and model you buy

For example, all Viessmann boilers are condensing boilers, and while this means they’ll be more efficient, it also means they’ll be more expensive.

Those are all things that will impact the cost of the boiler itself, but you also have to budget for installation, and this can range from $1,700 and $3,700 or more. The cost of installation depends largely on the same factors as above, such as where you live, the make/model/size of the boiler, and zones, as well as your home’s current plumbing infrastructure.

Finally, check for rebates any time you’re looking to buy HVAC equipment. Rebates might be available through a local HVAC distributor, your energy company, the government, or the manufacturer.

FAQ

Viessmann vs Bosch Boilers

Bosch boilers are typically more affordable than Viessmann. They also tend to be more efficient, and Bosch has some special technologies that Viessmann doesn’t. Bosch boilers are also more popular in Canada, but Viessmann has a long and solid global reputation for providing excellent quality and value for money.  

How long does a Viessmann boiler last?

The average lifespan of a Viessmann boiler is around 15 years, but you might be able to get 20 to 30 years from it with professional installation and regular maintenance.

Are Viessmann boilers expensive?

Viessmann is one of the more expensive boiler brands. However, they are known for their quality, reliability, and efficiency, which means the boiler might last longer and could save you more money on energy costs over its lifetime.

We review and compare the best boilers in Canada (including combi boilers) for 2024 to help Canadian homeowners and businesses choose the right hydronic heating system.

Home heating is always a major concern for Canadians, no matter what city or province you live in. Around 10 percent of Canadian homes are heated with boiler systems, which circulate hot water through pipes in the house to heat your home.

Older boilers tend to be louder and less efficient than newer ones. By 2025, all gas boilers and combi boilers sold in Canada will have an efficiency rating of at least 90%, so upgrading could save you a great deal of money on heating costs compared to an older boiler.

To help you choose the right system, Furnace Prices has compared some of the best boilers in Canada and evaluated them based on things like price, features, efficiency, warranties, and more. This guide will review the best boilers and combi boilers in Canada to help you decide which boiler system is best for your home, your needs, and your budget.

How We Evaluate the Best Boilers in Canada

Evaluating the best HVAC equipment is about more than just comparing the most popular brands and the cost for different models. Getting the right boiler can save you time, money, and headaches in the long run, even if you have to pay a little more upfront.

Here are just a few of the things we examine when reviewing the best boilers in Canada:

• Installation considerations, such as simplicity, costs, and mounting options
• Energy efficiency (a higher AFUE means lower operating costs month after month)
• Features and technologies that improve performance, durability, and operation
• The type of boiler system (such as conventional or combi)
• The warranty that comes with the boiler
• Material and construction quality
• Cost versus value
• Condensing versus non-condensing systems

Conventional Boilers Versus Combi Boilers

Combi boilers are on-demand systems that heat the water for your cooking, cleaning, and bathing needs while also providing the hot water for the boiler system, so you get heat and hot water from a single system.

While not as common as conventional boilers, combi boilers are becoming more popular because they have multiple benefits, such as:

• You don’t need a separate system for heating and domestic hot water
• You only have to buy one appliance, which can save money
• Cheaper installation compared to installing two appliances
• The units take up less space
• The best combi boilers are highly efficient

The Most Affordable Boilers in Canada

Boilers can be a major investment, but a good one will last upwards of 20 years.

In general, a new boiler unit could run anywhere from $1,200 to $5,000+, and that doesn’t include installation. With installation, a combi boiler will cost an average of $3,500 to $10,000+, and a conventional boiler could cost $5,000 – $10,000+ or more.

Other than installation, the major factors that will impact the cost of a new boiler include the fuel type, capacity, whether it’s a conventional/combi/condensing unit, efficiency, additional technologies, warranty, and more. Larger and more energy-efficient boilers will generally be the most expensive.

For example, condensing boilers tend to be among the priciest boilers because they have high-efficiency ratings and large capacities.

Here’s a list of some of the most affordable boilers in Canada right now:

Boilers with the Best Warranty Coverage

Warranties aren’t always something Canadians pay much attention to, but when it comes to HVAC equipment, a good boiler warranty can be worth its weight in gold. All new boilers sold in Canada must come with at least a basic warranty, but some manufacturers go above and beyond when it comes to standing behind their products.

The best warranties tend to come with higher-priced boiler systems, but that’s not always the case. A good warranty could save you hundreds or thousands of dollars in repairs and maintenance, so you’ll want to pay attention to the warranty offered with any new boiler.

Here are the best boiler warranties offered in Canada right now:

Boilers with the Best Features

Boiler systems have been used to heat spaces for over 150 years, and the systems have come a long way since the first designs were patented. The best boilers in Canada today are far quieter and more efficient than ever before.

Further, some manufacturers are also developing features that enhance performance, increase longevity, reduce the unit’s environmental impact, make their boilers easier to control, and more.

For instance, one feature that many modern boilers offer—have a look at the Rheem Prestige for an example—is an outdoor temperature monitor and reset function, so the boiler will automatically adjust the indoor temperature based on the outdoor temperature.

Beyond that, here are some of the best models on the market that have additional features and technologies you might appreciate:

Boilers with Great Turndown Ratios

A turndown ratio is the difference between the boiler operating in full-fire mode versus its lowest operating mode before shutting off. A boiler with a higher turndown ratio can operate at lower capacities to save energy and maintain the ideal temperature.

These are some of the boilers with great turndown ratios:

• Westinghouse Premier: 10:1
• Navien NHB: 15:1

Boilers with Green Features

• Daikin’s Altherma series boilers can be connected to solar power generation systems.
• Westinghouse’s Premier boiler promises extremely low nitrogen oxide emissions.
• Baxi’s THINK combustion management system monitors and tweaks the gas/air mixture in the system to reduce gas consumption and improve performance.
• Noritz’s NRCB combi boiler meets rigorous emission standards thanks to the fully modulating burner.

Boilers with Longevity and Durability Features

Modern boilers have an average lifespan of 15 to 20 years, but some manufacturers try to increase longevity and durability with features like:

• Chemical-resistant metal section connectors from Rand and Reardon
• A freeze protection safety device from Baxi
• Built-in two-stage frost protection with the Vaillant ecoTEC Plus combi
• MatriX-Plus burner with stainless steel MatriX surface on the Viessmann B2KB Vitodens 200W
• Corrosion-resistant primary and secondary heat exchangers on the Noritz NRCB combi

Boilers with Quiet Operation Features

• Vaillant’s ecoTEC Plus combi has a special flame lift detection system for quiet combustion
• Viessmann’s Vitodens 200-W has a low fan speed for quiet operation
• Rand and Reardon boilers have a step-opening gas valve for quiet startup

Boilers with Convenient Control and Enhanced Performance Features

• Navien NHB condensing boilers are controlled with the NHB Integrated control, which allows you to easily adjust heat capacity, the outdoor temperature reset, the turndown ratio timing, and more
• Navien NCB-E series combi boilers and NHB & NFB boilers have the option of a magnetic filtration system called NaviClean
• Daikin Altherma series boilers are monitored by the Daikin Eye for optimal performance
• Viessmann Vitodens 220-W has a user-friendly control system that lets you monitor and control settings and performance
• Many boilers can be controlled wirelessly from a smartphone or tablet, including:
  • The Vaillant ecoTEC Plus Combi
  • Bosch Greenstar boilers
  • Baxi 800 Platinum Combi
  • Viessmann Vitodens 200-W
  • Navien through their NaviLink system

Most Efficient Boiler Systems

The more efficient your boiler is, the less it will cost to heat your home (and maybe your hot water) every year. A boiler with a high annualized fuel utilization efficiency (AFUE) rating will typically cost more, but you will recoup that cost over the months and years thanks to the lower energy bills.

Home heating is one of the largest expenses you have as a homeowner, so buying a more efficient boiler will pay off in the end.

AFUE measures how much heat is transferred from the boiler to the water versus how much is lost during the heating and transferring process. The higher the AFUE, the less energy is lost, and the less it will cost to heat your home. You can also look for the ENERGY STAR logo, which guarantees that a gas boiler uses 10% less energy than a standard boiler.

Older boilers can have AFUE ratings as low as 50 percent, and that means 50 percent of the energy is being wasted. By comparison, modern high-efficiency boilers have AFUE ratings between 90 and 98 percent, meaning as little as 2 percent of the energy is wasted.

Condensing boilers are among the most efficient because they recycle the heat from water vapor in the system, so they require less energy to preheat cold water coming into the boiler.

Because of this design, condensing boilers use more of the energy they draw and have lower operating temperatures, making them more efficient overall. That’s not to say that non-condensing boilers can’t be energy efficient.

Let’s look at some of the most efficient boilers on the market:

Boilers with the Easiest Installation

While ease of installation might not be something you really care about when you pick out your boiler, there’s one reason why you might want to give this some thought: it can impact the installation cost. In general, the easier a boiler system is to install, the more you’ll save on labour costs for an HVAC expert.

Boiler installation can cost anywhere between $1,000 and $4,000, depending on factors such as:

• Boiler type
• Boiler size
• How many zones must be connected
• Installation location
• If additional lines or pipes are required

Because installation can be such a large cost, quite a few boiler manufacturers have started focusing on improving ease of installation by making their boilers more compact, lighter, and less complex to hook up. Here are some examples of boilers that have been designed for quicker and easier installation:

• Daikin Altherma series boilers: all parts are accessible from the front of the unit, making installation faster and easier, and the compact size means it can be installed in small spaces, such as cupboards
• Baxi’s 800 Platinum Combi boiler is lightweight and compact, and has front access for quick and simple maintenance
• Vaillant’s atmoTEC, ecoTEC, and turboTEC Plus boilers come with a pipe cut-out and adjustable wall bracket for fast installation
• Slant/Fin’s Victory VHS Series boilers have contractor-friendly features that promise fast installation and maintenance, and they don’t require a chimney, which increases installation choices
• Bosch Greenstar boilers are designed for fast installation and to be low maintenance
• NTI’s Vmax series boilers are equipped with down-fired fire tube stainless steel heat exchangers that make installation and service quicker and easier
• Ideal’s Vogue Max combi boiler is lightweight and compact for faster installation
• Rheem’s Prestige boilers have been designed with low installation costs in mind, and have low-cost and easy-to-install venting

Getting the Most from Your Boiler System

You could buy the best boiler in Canada or the top combi boiler and still have problems if you don’t get it installed professionally.

A professional, trained, and certified HVAC technician will make sure your boiler is the right size, that it’s installed properly, that it doesn’t get damaged in the process, and that it’s working as efficiently as possible.

A professional installer can also help you with tips like insulating the pipes, bleeding the air, checking the pressure, and cleaning the radiators, which will all improve efficiency and performance.

After that, annual inspections and maintenance are also important for the efficient operation and long life of your boiler. Plus, regular maintenance will help to prevent major breakdowns that could be very costly to fix.

Again, you’ll want to use a trained and certified HVAC expert for all inspections, maintenance, and repairs, otherwise you could do more damage than good for your boiler.

✔ Expert-reviewed for accuracy and completeness.

Buying a new boiler system is like buying any large appliance in that it’s an investment, so it’s a good idea to do some research before choosing a new system for your home.

We’ve put together this comprehensive buyer guide for boilers and hydronic heating systems, including how boilers work, different types, pros and cons, key considerations and features, pricing, fuel sources, and how to choose the right one for your needs.

Boiler Systems Overview: What They Are and How They Work

A boiler system is a home heating method that uses hot water or steam to warm your house. These systems are sometimes referred to as hydronic systems, and this heating method can even be used to warm swimming pools or de-ice driveways in winter.

Here are the basics of how the process works:

1. Water is housed in a boiler and then heated
2. The heated water or steam is then pumped around the house within a closed-circuit system of pipes connected to radiators, coils, or a radiant floor system
3. As the hot water circulates through the system, it transfers heat to the air or floor, thereby warming the house
4. After circulating through the system, the cooled water is pumped back to the boiler to be reheated and recirculated

Most boiler systems use propane, natural gas, or oil as their fuel source to heat the water, but electric systems do exist as well. There are also combi-boilers on the market that serve the dual function of heating your house while also providing your home’s hot water.

Boiler Systems vs. Forced-Air Heating Systems

The main alternative to boiler systems is a furnace, which heats your home by warming air and distributing it through the house via a duct system. Boilers and furnaces heat in a similar way, with the main difference being that boilers distribute hot water through pipes and radiators, while furnaces heat the air directly and then circulate it around the house.

Most homes in North America are heated with a forced-air furnace, though there are still plenty of homes (especially older ones) that have boiler systems instead.

Pros and Cons of Boiler Heat

Pros

Cons

Even heat: One of the best things about boiler heat (especially compared to forced-air systems) is they distribute heat evenly throughout the house, so you won’t find yourself contending with cold spots, chilly rooms, and fluctuating temperatures around the house. They also tend to maintain a more consistent temperature, as forced-air furnaces are known for sometimes causing peaks and dips as the furnace cycles on and off.

Silence: Newer hydronic heating systems are extremely quiet, to the point where you probably won’t even know the system is running. However, it should be noted that if you have an old system in your home, then the radiators can be quite noisy as they heat up and cool down, and they may ‘clang’ at times.

Zone control: Even if you don’t have zone control set up already, it’s simple and easy to add this feature to your system, allowing you to manage and customize how heat is distributed throughout your house. Simply shutting the valve for a radiator in a given part of the house can work as well.

Clean air: Hydronic systems don’t rely on air to heat your home, so they provide a cleaner living space in terms of air quality. Furnaces can push dust, dirt, allergens, and other particulates around your house, so boiler systems are ideal if air quality is a top concern. That being said, forced-air systems with advanced air filtration systems can actually help keep your home’s air cleaner.

Economy: For the most part, boiler systems are cheaper to run than forced-air ones, and this means you can keep your family comfortable for less during the cold winter months. (Note there are obviously many variables to the cost of heating a home, including its size, insulation, fuel type, where you live and local climate, and personal preferences and useage, among others)

Maintenance: Boiler systems require very little maintenance, including that you don’t have to replace filters regularly.

Comfort: Although this is a matter of personal preference, many people find the heat from boiler systems—including from radiators, baseboards, or in-floor systems—is more comfortable than the heat provided by furnaces. Forced-air heating, especially with a cheaper or single stage furnace, and a poorly-insulated home can have a tendency to cause temperatures to fluctuate.

Installation costs: Boiler systems can be a bit more expensive to install than forced-air ones, and this is especially true if your home needs to be outfitted with all the piping, radiators, and other infrastructure.

Replacement costs: If anything ever malfunctions or breaks with a boiler, the cost for replacing parts tends to be somewhat more expensive than with a forced-air system.

Slower temperature response: When most people change the thermostat, they expect instant results from their heating system, but boilers can take longer to adjust to new temperature settings as the radiators are filled with hot water, thus taking longer for heat to dissipate than the air from a forced-air heating system.

Over-heating: This is more of a problem in apartment buildings or other situations where you may not have direct control over the system, thus sometimes leading to the system heating your living space beyond what is comfortable. Although this can also occur in a single-family home because as mentioned above, boiler and radiator heating systems tend to respond more slowly and therefore it can take longer to lower the ambient temperature. This can also be wasteful as people may resort to opening windows in the middle of the winter to cool rooms down.

No cooling option: Boilers can’t be combined with a home cooling system, nor can they be used to cool your home during the summer months. Because of this, you will need a separate infrastructure like ductwork for an air conditioning system, or relying on ductless systems.

Potential for water leaks: While this problem is rare, boilers do come with a risk for water leaks.

The Different Types of Boiler Systems

There are three main types of boiler systems: conventional, combi, and system boilers. These three boiler systems all have their own advantages and disadvantages, and choosing the right one is all about comparing your needs with the pros and cons of the different systems.

Understanding these different types and how they work can help you make the right choice when it comes time to select a new unit.

Conventional Boilers

The conventional, regular, or open-vent boiler is among the most common type of boiler system, though it should be noted that combi-boilers have been growing in popularity over the past few years. These systems have a water tank and a water cylinder for hot and cold water.

The cold water is stored in the water cylinder, then heated and transferred to the hot water tank for storage. When the thermostat kicks on, the water is pumped from the hot water storage tank through the boiler system to heat your home.

Pros

Cons

Storage and capacity: Conventional boilers have a large storage tank for hot water, and this means it’s uncommon for the hot water to run out, so your house should always remain at a comfortable temperature.

Single-function: Because conventional boilers are separate from the water heater used to provide your home with hot water, you can heat your home, have a shower, do laundry, and otherwise use the hot water at the same time without worrying that your shower will run cold halfway through lathering up.

Independence: Although conventional boilers occasionally need topping up, for the most part, they can function independently of the water main, so you’ll still have heat in the event of a problem with your water line.

Overhead Cost: For a lot of homeowners, the biggest downside with conventional boilers is that they can be somewhat less efficient given that they heat a large tank. This is especially the case if the tank is poorly-insulated. This means you may end up paying more in the long run to heat your home.

When you consider that heating your home accounts for the largest portion of your energy bill, you can see the impact a lower-efficiency unit might have on your monthly costs.

Space: Another drawback with conventional boilers is they require the most space, so they’re often not suitable for apartments, condos, and other small dwellings that don’t have a lot of extra storage space. The radiators themselves also take up space in a room.

Capacity: Even though conventional boilers do have a substantial hot water tank, it is still possible that the tank is not sufficient to keep up with heating demands, especially during a cold snap when you may want to raise the entire home’s temperature in a short amount of time.

For the most part, this shouldn’t be an issue as long as your boiler system is properly sized for your home.

Cost: Conventional boilers are larger and have more parts than the other boiler styles, so even though they’re less efficient, they’re also more expensive to buy.

Combi-Boilers

As the name suggests, combi-boilers combine the work of two major appliances into one: the boiler and the water heater.

These units draw cold water in directly from the mains as needed and heat it on-demand, so there’s no need for a storage tank. Once the water is heated, it is either pumped through the boiler system to heat your home or distributed to the faucets and water lines as needed to provide your kitchen, bathroom, utility, and laundry rooms with hot water.

Although storage tanks aren’t required with combi-boilers, they can be purchased separately (and then the system becomes a combi-storage boiler) if your hot water needs exceed the on-demand capabilities of the boiler.

Pros

Cons

Unlimited hot water: Combi-boilers work using the same principle as on-demand water heaters, so you have access to as much hot water as you need for your heating system and your household tasks as you need it.

Space-savings: Because combi-boilers don’t need additional space for a storage tank, they take up significantly less room than both conventional and system boilers. These units are very compact and can fit in a space as small as a kitchen cupboard, making them ideal for smaller homes and dwellings.

Price and convenience: Thanks to their size and ease of installation, combi-boilers are also the most affordable type of boiler for both upfront purchasing costs and installation fees.

Water Pressure: Although there are certain instances where this can be a problem, combi-boilers typically provide great water pressure.

Energy-efficiency: Most combi-boilers are high-efficiency units, and many even offer an ENERGY STAR rating so you can rest assured that you’ll spend less heating your home and your water.

Water pressure loss: As mentioned, combi-boilers typically have strong water pressure, but this can fluctuate if the demand for water peaks in your home. For instance, if one person is running a bath while another is doing dishes, then you’ll likely lose some pressure at both faucets. Similarly, the water pressure depends on the pressure from the main water line, so if that’s low then water pressure will continue to be a problem.

System-Boilers

Sealed system boilers only require a small water cylinder and not a tank as well, and this means they can fit in much smaller spaces than a conventional boiler. They work by drawing cold water in from the mains, heating it, and then using the water cylinder to store the hot water until the thermostat kicks on and the water is circulated through the system.

Pros

Cons

Space-savings: Although system boilers aren’t quite as small and compact as combi-boilers, they still take up much less space than conventional ones thanks to the smaller water cylinder so they can be suitable for smaller homes and apartments.

Multiple use: System boilers are separate from the water heater, so you can access hot water from multiple faucets at the same time without compromising the boiler’s ability to heat your home.

Ease of installation: System boilers are easier to install than conventional ones, and this translates to faster, cheaper, and easier installation.

Water pressure: These units rely on the main water supply, so as long as you have a strong flow coming in from the mains, then you’ll have great water pressure with these systems.

Hot water when you want: System boilers don’t heat water on-demand, but they do store heated water so that it’s ready and available when you need it.

Cost-savings: System boilers tend to be somewhat more expensive than combi-boilers, but they’re still much more affordable than their conventional counterparts, making them ideal for people on a tighter budget.

Limited storage and reheating delays: Because system boilers have a smaller storage capacity than conventional ones, the possibility of running out of hot water is higher with this type of system. When the hot water does run out, the system will need time to refill and reheat the water, and this can impact the temperature in your home.

Space is required: The water cylinder that system boilers use is much smaller than the storage space needed for a conventional boiler, but you do still need to allocate storage space for the cylinder, which can be tough in smaller homes.

Less energy efficient: Although these systems are more energy-efficient than conventional boilers, they aren’t as efficient as combi-boilers, and that means your energy bills will be slightly higher each month.

Pressure is dependent on mains: If the pressure from your mains isn’t adequate, then the system boiler won’t have the pressure it needs to work optimally.

More expensive than combi: The price range between combi and system boilers isn’t enormous, but you will pay more for a system boiler and more for the installation. That being said, both these boiler types are still cheaper and easier to install than a conventional boiler.

Fuel Type and Lifecycle Cost

One of the most important decisions you’ll have to make when buying a boiler is the fuel type (natural gas, propane, oil, solid fuel like wood or coal, or electric). Fuel accounts for the largest lifecycle cost of a boiler, so you need the information and resources to select the most energy-efficient system for your needs.

To help you with this, here’s a comparison of the advantages and disadvantages of different fuel types.

Natural Gas

Advantages of Natural Gas Boilers:

Disadvantages of Natural Gas Boilers:

• Natural gas is the cleanest of the fossil fuels in that it emits lower levels of greenhouse gasses
• This fuel is completely odourless
• There’s no need for a storage tank because the gas comes from the grid
• Natural gas boilers are generally cheaper to operate than electric or oil ones

• You do need to be connected to a gas line, and this will require professional installation if you don’t already have the infrastructure in place
• Gas prices are continually rising
• You need a reliable source of fuel and need to be connected to the gas grid
• Annual servicing and maintenance are required for safety reasons
• Even though extremely rare, the fear of a gas leak makes some people apprehensive

Propane

Advantages of Propane Boilers:

Disadvantages of Propane Boilers:

• Propane only has a faint odour, especially when compared to oil
• These boilers are highly efficient
• You don’t have to be connected to the gas or electrical grid
• Propane can be stored as a pressurized liquid, so storage requirements are minimal

• Installation of a new unit will be more expensive than with a gas or electric boiler
• You have to monitor your fuel level and reorder as necessary
• Propane prices are also on the rise
• Propane has more of an environmental toll compared to gas or electric boilers
• Annual servicing and maintenance are required
• A large storage tank needs to be installed on your property

Oil

Advantages of Oil Boilers:

Disadvantages of Oil Boilers:

• You don’t have to connect to the gas or electrical grid
• Oil boilers are cheaper to run compared to electric ones
• Oil prices are more stable than natural gas and propane so you can budget more effectively

• Oil isn’t as affordable as natural gas, it produces more greenhouse gas emissions than gas and propane, and it has a strong odour
• You have to monitor your fuel levels and reorder stock
• Oil tanks require more space than propane
• Oil suppliers may require payment on delivery for bulk quantities

Solid Fuel

Advantages of Solid Fuel Boilers:

Disadvantages of Solid Fuel Boilers:

• Wood-burning is carbon-neutral when burned properly
• Wood is flammable but not explosive
• Wood doesn’t leak
• You don’t have to connect to the gas or electrical grid
• Wood and coal are cheaper than other fuel sources

• You have to contend with smoke and be wary of carbon monoxide emissions
• Coal is not an environmentally friendly fuel
• Wood and coal need to be picked up or delivered to your home, and you need space to store them safely
• You have to monitor levels and restock fuel as needed
• Maintenance is required much more frequently (sometimes daily)

Electric

Advantages of Electric Boilers:

Disadvantages of Electric Boilers:

• Efficiency ratings are as high as 99 percent
• They’re compact and easy to install
• There aren’t any greenhouse gasses or other dangerous emissions
• These units don’t need a flue or air intake system
• There’s no need to connect to the gas grid or store fuel
• There’s no risk of fires, leaks, or explosions
• Electric boilers can be more environmentally friendly, depending on the power/fuel source that your utility uses

• Electricity typically costs more than combustible fuels
• You do have to connect to the electrical grid
• Your home won’t have heat in the event of a power outage
• Electric units can’t heat water to as high a temperature as combustion boilers
• These units can only heat small amounts of water at once, so they’re not suitable for large homes

Boiler Prices

How much does a boiler cost?

The final cost of a boiler will depend on many factors, but the average price including installation can be anywhere from $4,000 – $8,000+ for a boiler or combi-boiler, and all the way up to $10,000 or more for a large unit or more complex installation.

Note this is for a residential boiler system. Commercial boilers for apartment buildings and other large-scale applications can cost far more. Either way, it’s best to speak to a professional for a custom estimate.

Some factors that can affect the final cost of your new boiler system installation include:

• The style, make, and brand
• Fuel type
• Installation costs
• Boiler capacity and output (based on your home size)
• Efficiency
• Special or additional features and technology
• Current heating system infrastructure (and whether it’s compatible with the new system)

What Boiler to Buy: Choosing the Right System

When it’s time to buy a new boiler, the best place to start is by examining the needs of your home and family, including factors like the size of your house, the number of people in your family, your daily hot water requirements, how many bathrooms you have, and even the reliability of the water pressure from your mains.

To help you out with your decision here’s some more information about the different boiler types and when they’re ideal.

Conventional boilers are ideal when:

• You have a large family
• Hot water is often required from multiple faucets at the same time
• Your family has high hot water needs and uses hot water for extended periods throughout the day
• You have available space that could be used to house the storage tank and water cylinder
• Your house has three-plus bathrooms
• The water pressure coming from your mains tends to be low

Combi-boilers are ideal when:

• There’s limited storage space in your home (maybe you don’t have a large basement, don’t have an attic or loft, and don’t otherwise have anywhere to store a large tank)
• Your family tends to use a lot of hot water throughout the day
• Your home doesn’t have more than one bathroom
• Hot water in your home is usually only required from one or two faucets at a time
• The water pressure from your mains is ample

System boilers are ideal when:

• You need hot water from several taps at the same time
• You have a smaller home and family
• You don’t use a lot of hot water, nor for extended periods
• There’s some storage space available for the water cylinder (you don’t necessarily need an attic or loft)
• There are no more than two bathrooms in your home
• The water pressure from your mains is reliable and high

Key Considerations When Choosing a Boiler

Air-Intake and Flue Gas Systems for Combustion Boilers

All combustion boilers (ones powered by natural gas, propane, solid fuel, or oil) require uninhibited air intake and flue gas systems for safety and efficiency.

Because of this, you also have to be mindful of location when you want to install or move a combustion boiler: there needs to be good airflow, a fresh-air supply, and nearby exhaust to vent emissions produced during the combustion process.

If you are looking at a combustion boiler, you might also want to consider outfitting the unit with an electronic ignition technology that can eliminate the need for a pilot light that’s always burning.

Size and Output

The size of your home is an important factor to keep in mind when selecting a boiler. For instance, compact combi-boilers wouldn’t be effective for large homes with multiple bathrooms and several family members. Conversely, a large conventional boiler wouldn’t be a suitable option for a small apartment or studio, simply because you won’t have the storage space required to house the tank and cylinder.

If you’re not sure what capacity your boiler should be, there are many online boiler size calculators you can use as a reference.

Mains Pressure

Water pressure is another thing you’ll have to keep in mind when determining your boiler type, because both combi-boilers and system boilers both require high and reliable water pressure from the main water supply to perform optimally.

Only conventional boilers are suitable if your mains water pressure is low, but there are solutions if water pressure is an issue in your home. For one thing, if you have low water pressure and don’t have the storage space for a conventional boiler, then you can opt for a combi-storage boiler system.

On the other hand, if you do have adequate water pressure but don’t want a conventional boiler, a system boiler will be cheaper to buy and install, and you’ll still have a reliable capacity even if you have a large household.

Energy Efficiency and Condensing Boilers

Energy efficiency is a key consideration for most homeowners looking to buy new appliances, and in general, the more efficient a boiler is, the more it will cost up front. But it’s important to remember that energy-efficiency will translate to long-term savings as far as energy and fuel use are concerned, and it won’t take long for you to recoup the additional money you spent for the better boiler.

Pro tip: When looking for energy-efficient boilers, look for features like condensing flue gas systems and modulating burners.

Moving a Boiler

There are many reasons why you might need to move a boiler, including that you’re doing some renovations or that you have to relocate the system for safety reasons.

Moving a boiler requires expertise that only professionals can provide, and the cost for this service can cost $1,000 – $1,500 or more. It’s hard to provide firm estimates as each home and situation is different, and things like how far it’s being moved and how much labour and materials are required, will affect the final cost.

The total cost will depend largely on the components that have to be moved, as each has its own approximate cost associated with it:

• Boiler flue: $120 – $200
• Extension flue pipes or flue bends: $70 per meter
• Magnetic filter: $170 – $200
• Controls: $120 – $1100
• Pipework or fittings: $500 – $1,000

Helpful Maintenance Tips to Get the Most from Your Boiler

Your boiler is an investment, and you want to make sure you get the most life out of your system, not only so you can save money, but also so you can keep your family comfortable for longer. Here are some great tips to help you maintain and optimize your boiler system:

1. Insulate the pipes: By insulating the hot water pipes coming from your boiler, you can save money by reducing heat loss and increase the speed with which your system can warm your house and respond to temperature adjustments
2. Bleed the air: Sometimes radiators get air bubbles, so it’s a good idea to bleed the air from them every six months. That way, you guarantee the pipes are properly filled with water, and this will maximize the system’s efficiency and functionality.
3. Vacuum the radiators: Dirt, dust, and other particulates can build up on the radiators and make them less efficient, and you can combat this by vacuuming the radiators regularly.
4. Check the water: Water expands when heated, so to keep the pressure from building up inside the system, boilers are equipped with expansion tanks. It’s important to check the water level in the expansion tank regularly to ensure it’s correct.

Glossary of Common Boiler Terms

Allowable working pressure: This is the maximum pressure a particular boiler can withstand.

Combustion: Refers to the act or process of burning. Technically, it’s characterized by rapid oxidation that’s often accompanied by heat and light.

Condensate: Water that condenses after you remove the heat from steam.

Corrosion: Destruction or damage to metal as a result of chemical action.

Flue: A duct that allows smoke and waste gasses to vent safely from the house.

Natural gas: A flammable gas (often methane and other hydrocarbons) that occurs naturally underground.

Pilot/pilot light: A small gas burner that’s always burning to light a larger burner when needed.

Radiant: Refers to heat transmitted by radiation instead of conduction or convection.

Safety valve: A valve that automatically opens and vents when the pressure reaches a certain level.
