An Overview of the Navien Brand

Strong Points

Navien as a brand has a lot to offer Canadian consumers. Along with making reliable and durable boilers, they also focus on technologies that improve performance and make their boilers easy for homeowners to operate and adjust.

All of their boilers are condensing, meaning they’re more efficient than conventional boilers, so every one of their models has a good AFUE rating and ENERGY STAR® certification. Navien boilers are also compact and affordable, making them ideal for many homes and homeowners.

The brand also has a line of combi boilers that supply hot water for your home heating system and your domestic hot water needs. These units can save you money if you’re looking to upgrade two appliances at once because you can get a two-in-one combi boiler.

Room for Improvement

One of the great things about Navien boilers is that they are efficient, so they’re guaranteed to save you money month over month compared to an older boiler. However, their boilers aren’t the most efficient on the market, and they don’t offer a wide selection of boilers with different AFUE ratings.

If you go with a Navien boiler, then you’re getting a boiler that’s 95 percent efficient. While that’s good, it’s not the best, and it might not be enough for homeowners who are really concerned about fuel use and energy costs.  

The Bottom Line

Navien’s high-efficiency condensing and combi boilers have great value for the price. They’re efficient, affordable, and reliable, but they also have some great new technologies that make controlling your heating system and customizing your home comfort a breeze.

Plus, Navien products are compact, economical, and available in a wide range of sizes and outputs, so it’s pretty much guaranteed there’s a Navien model that will meet your needs.

Navien Average Boiler Price Range

$4500 – $7000+ 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.

Navien Boiler Options Reviewed

Condensing Boilers:  NFB Series and NHB Series

The NFB and NHB series 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.

The boilers in this series are compatible with NaviLink, a Wi-Fi enabled control that can give you access to your heating system from anywhere in the world.

Condensing Combi Boilers: NCB-E Series and NFC Series

It used to be that you had to choose between combi boilers and condensing boilers, but Navien was one of the first brands to offer the high-efficiency condensing combi boiler with their NCB-E and NFC Series models.

Not only can these boilers provide heat for your home and hot water for all your cooking, cleaning, and bathing needs, but they’re also more energy efficient because they recycle exhaust gases that traditional combi boilers might waste. 

The boilers in these series are high-quality and designed to last, and when paired with the NaviLink system, they can let you adjust settings for your heating and hot water systems remotely.

Comparison of Navien’s Top Models

In this section of our Navien review, we’ll compare their models and the key features of each one.

Navien’s Boiler Warranty

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

An Overview of the Viessmann Brand

Strong Points

Viessmann is one of the oldest and most popular boiler manufacturers, and Canadian homeowners have been trusting their products for decades. They have a decent selection of condensing and condensing combi boilers in a range of sizes, and they have both affordable and pricier models.

Every Viessmann boiler is ENERGY STAR® certified, was awarded the ENERGY STAR Most Efficient of 2020, and has an AFUE rating of 95 or 98 percent. Viessmann also equips their boiler systems with some unique design features, and they back their products with a good warranty.  

Room for Improvement

Most consumers and HVAC experts don’t have much to say against Viessmann or their products. They don’t have a huge selection of condensing gas boilers and they don’t have too many innovative technologies beyond technical and design features, but they make excellent and high-quality boilers that homeowners in Canada and around the world love.

The Bottom Line

Viessmann boilers are durable, reliable, efficient, quiet, and designed for lasting performance. They don’t have a ton of novel features and technologies the way some competitors do, but that’s because they focus their attention on proprietary designs that increase the lifespan and performance of their boilers.

You can find affordable Viessmann boilers that are high-efficiency and backed by a decent warranty, so these systems are sound investments that will save you plenty on energy bills.

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.

The warranty that comes with your boiler might not seem like the most important thing, but it is something you should pay attention to. For one thing, a good warranty could potentially save you hundreds or even thousands of dollars in repair costs throughout the warranty period.

Just as importantly, a good warranty means that the manufacturer stands behind their product for at least the length of the coverage period, so warranty terms can indicate the quality and reliability of the boiler.

Viessmann backs up all of their boiler models with the same decent warranty, which includes:

•  A two-year parts or standard equipment warranty for components like the burner, controls, and boiler enclosure
• A 10-year warranty for the pressure vessel
• A prorated limited lifetime warranty for the pressure vessel beyond year 10

VIESSMANN: ABOUT THE COMPANY

Viessmann was founded in Germany back in 1917, and today the international company is still family-owned. Viessmann is a household name all over the world, and homes and businesses around the globe are kept warm every winter with their high-efficiency condensing and condensing combi boilers and other products. Along with manufacturing high-quality boilers, Viessmann also focuses on environmental responsibility, energy efficiency, quality engineering, and affordable comfort.

We review and compare the top boiler & combi-boiler brands and models for 2022, 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. As soon as the cooler weather starts settling in and the leaves start changing in fall, you know that winter is just around the corner.

Whether you’re the type of person who cranks the thermostat as soon as the weather starts to turn or the type who breaks out the blankets and sweaters in hopes of delaying turning on the heat, it’s always important to have a reliable heating system.

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 can be problematic in that they tend to be louder and less efficient than newer ones, and upgrading could save you a great deal of money on heating costs. But what should you look for when buying a new boiler system? What brands should you trust, and how much should you expect to pay?

Furnace Prices has compared some of the most popular boiler brands on the market 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 Boiler Systems

Evaluating the best HVAC equipment is about more than just comparing the most popular brands and the cost for different models.

There are many things to think about when comparing boiler systems, and while price may be one of the most important you consider, we also want to give you other crucial information.

We look at warranties, installation, efficiency ratings, and new technologies because 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

Every home in Canada needs a home heating system, as well as a water heater that provides the home with hot water for cooking, cleaning, and bathing. Most homes have separate HVAC units for these functions, like having a water heater plus a furnace for heat.

A combi boiler eliminates the need for having a separate water heater and home heating system because it does both. Combi boilers are on-demand systems that heat the water for your cooking and cleaning needs while also providing the hot water for the boiler system, so you get heat and hot water from a single system.

Combi boilers have been steadily growing in popularity over the years, largely because they tend to be more affordable than conventional boilers, they save space, they’re usually highly energy efficient, and they provide hot water on demand.

Even though they’re not as common as conventional boilers, we’ve still included them in this best boiler guide.

A conventional boiler, on the other hand, only provides hot water for the boiler system, and not for your domestic hot water use. In other words, with a conventional boiler, you still need a separate water heater system for your daily water demands.

The Most Affordable Boilers in Canada

Boilers can be a major investment, but a good one will last upwards of 20 years. This guide will go over all the important factors you should consider when buying a boiler, but we know that Canadian homeowners are always having to watch their pennies, so the first thing we’ll look at is the most affordable boilers on the market.

In general, a new boiler could run anywhere from $1,300 to $4,500, and that doesn’t include installation. With installation, a combi boiler will cost an average of $3,000 to $5,000, and a conventional boiler could cost $5,000 or more.

Other than installation, the major factors that will impact the cost of a new boiler are the type of boiler, the capacity, and the energy efficiency. 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. Today’s boilers 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:

• Baxi Duo-tec Compact 30GA: 7:1
• 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
• 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

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 boiler is efficient and that it performs better than others in its class.

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

No matter if you buy the most affordable and most basic boiler or the best and priciest boiler, there are still steps you can take to get the best performance and longest life from your boiler. The most important thing starts at the beginning of your boiler’s life, and that is professional installation.

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.

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

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.

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.

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.

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

Propane

Oil

Solid Fuel

Electric

Boiler Prices

The final cost of a boiler will depend on many factors, but the average price including installation can be anywhere from $3,000 – $5,000+ for a combi-boiler, and all the way up to $5,000 or more for a conventional boiler. 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)

Top Boiler Brands

When it comes time to purchase a new boiler system, knowing the top brands can help narrow your search and give you peace of mind that you’re choosing a reliable and top-quality system that will last for many years. With that in mind, here’s a breakdown of the top boiler brands that have been keeping Canadians warm throughout the winters.

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 range anywhere from $500 to $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 is 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.
