Average New Boiler Cost in Canada (2026)
The average cost of a new boiler in Canada ranges from $2,500 to $7,500 CAD including installation. The exact price depends on the boiler type, brand, your property size, and the complexity of the installation.
Here's a quick breakdown of typical 2026 prices: Combi boilers range from $2,500 to $5,500 installed, system boilers from $3,500 to $6,500, and conventional (heat-only) boilers from $3,500 to $7,500.
Combi Boiler Costs
Combi (combination) boilers are a popular choice in Canadian homes. They heat water directly from the mains on demand, so there's no need for a separate hot water cylinder or cold water storage tank.
Budget combi boilers from brands like Baxi or Ideal start from around $2,500 installed. Mid-range options from Vaillant or Worcester Bosch typically cost $3,500 to $4,800. Premium models with extended warranties can reach $5,500.
System Boiler Costs
System boilers work with a separate hot water cylinder and are ideal for larger homes with multiple bathrooms. They provide a strong, consistent hot water flow to several taps simultaneously.
Including installation, system boilers typically cost between $3,500 and $6,500. The additional cost compared to combi boilers reflects the need for a hot water cylinder and potentially more complex pipework.
What Affects Boiler Installation Costs?
Several factors influence the total cost of a boiler installation beyond the boiler unit itself. The main factors include: the type and size of boiler, whether you're relocating the boiler to a different position, the complexity of existing pipework, any additional components needed (thermostats, valves, filters), and whether scaffolding is required for flue installation.
If you're switching from a conventional boiler to a combi, the cost can be higher as the installer needs to remove the old hot water cylinder and cold water tanks, and potentially reroute pipework.
How to Save Money on a New Boiler
There are several ways to reduce the cost of a new boiler. First, get multiple quotes — we recommend at least three. Look for companies that offer finance options to spread the cost. Check if you're eligible for government grants such as the Canada Greener Homes Grant, which offers rebates towards energy-efficient home upgrades.
Choosing a reputable installer like FlowFix Pro means you'll get a competitive price, professional installation by TSSA licensed technicians, and up to a 12-year manufacturer warranty. We offer free, no-obligation quotes with transparent pricing.
When Should You Replace Your Boiler?
Most boilers last between 10 and 15 years. Signs that your boiler may need replacing include: increasing energy bills, frequent breakdowns and repair costs, uneven heating, strange noises, and the boiler taking longer to heat your home.
If your boiler is over 10 years old and costing you in regular repairs, a new high-efficiency boiler could save you hundreds per year on energy bills according to Natural Resources Canada.
