In Calgary, the cost of a new boiler system depends on the size of your home and how efficient you want the unit to be.

• Standard Replacement: For a typical Calgary home, a new boiler with installation generally ranges from $8,500 to $12,000. This usually includes the unit, labor, permits, and basic setup.

• High-Efficiency or Large Homes: If you have a larger property, multiple heating zones, or are installing a top-tier condensing boiler, costs can range between $12,000 and $20,000+.

• Combi-Boilers: If you want a unit that handles both your home heating and your "on-demand" hot water for showers, these typically start around $11,750 installed.

In most Calgary homes, you’ll find the boiler in the mechanical room or basement, usually near the water heater. However, because modern boilers are much smaller than they used to be (some are about the size of a large suitcase), they can also be found:

In a utility closet: Tucked away on a main floor.

Wall-mounted: Many new high-efficiency units hang on the wall to save floor space.

In the garage: Sometimes located in a heated garage or a dedicated mechanical bump-out.

No. In Alberta, you cannot legally install your own gas boiler unless you are a certified journeyman gasfitter.

The Rules: The City of Calgary requires a specific Hydronic Permit for the piping and a Gas Permit for the fuel line.

The Risk: Because boilers involve high-pressure water and natural gas, an amateur installation is a major safety risk. Additionally, doing it yourself will likely void the manufacturer’s warranty and could lead to issues with your home insurance if something goes wrong.
