How much does hydronic floor heating cost for a Calgary whole-home install?

A whole-home hydronic floor heating system in a Calgary home costs $15,000 to $35,000 installed, depending on the home's size, number of zones, boiler type, and whether it is new construction or a retrofit. Hydronic radiant floor heating is the most comfortable and energy-efficient way to heat an entire Calgary home, but the upfront investment is substantial and the system is most practical when installed during new construction.

Cost breakdown for a typical 2,000-square-foot Calgary home (new construction):

Boiler or water heater: $3,000 to $8,000. A high-efficiency condensing boiler (95%+ AFUE) is the standard choice for whole-home hydronic heating in Calgary. Brands like Navien, Viessmann, and Rinnai are widely used by Calgary installers. A condensing boiler can also provide domestic hot water, eliminating the need for a separate hot water tank.

PEX tubing: $1 to $2 per linear foot installed. A 2,000-square-foot home requires approximately 3,000 to 5,000 linear feet of PEX tubing, running $3,000 to $10,000 depending on tube spacing (closer spacing provides more heat output). Standard spacing is 8 to 12 inches on centre.

Manifold and controls: $1,500 to $3,000. The manifold distributes heated water to individual zones, and each zone has its own actuator and thermostat. A typical whole-home system has 4 to 8 zones — bathrooms, bedrooms, living areas, kitchen, and basement each on independent control.

Circulation pump(s): $500 to $1,500. Variable-speed pumps are more energy efficient and quieter than fixed-speed.

Labour: $5,000 to $12,000 for the complete installation including tubing layout, manifold connection, boiler installation, and system commissioning. In new construction, the PEX tubing is stapled to insulation over the subfloor or embedded directly in the basement slab before it is poured.

Retrofit costs are significantly higher. In an existing Calgary home, the PEX tubing must be installed in channels cut into the subfloor from below (if accessible from the basement), or in sleeper channels built on top of the existing subfloor, which raises the floor height by 1.5 to 2 inches. Retrofit hydronic systems typically cost $25,000 to $50,000 for a 2,000-square-foot home — sometimes making the project impractical unless a major renovation is already planned.

Operating cost advantage: Natural gas in Alberta is significantly cheaper per BTU than electricity. A hydronic system heating a 2,000-square-foot Calgary home costs approximately $150 to $250 per month in gas during winter, compared to $300 to $600 or more for equivalent electric radiant mat coverage. Over 15 to 20 years, the operating cost savings can offset much of the higher upfront investment. Calgary's natural gas rates, while variable, have historically been among the lowest in Canada thanks to Alberta's proximity to production.

Permits and inspections: A whole-home hydronic system in Calgary requires a plumbing permit for the boiler and piping and a gas permit for the boiler's gas connection. A Safety Codes Officer must inspect the installation. If the system includes any electric components (pumps, controls connected to new circuits), an electrical permit may also be required. Ensure your installer carries WCB Alberta coverage — a project of this scope involves significant on-site labour.

For a whole-home hydronic system, you will want to work with an HVAC contractor who specializes in radiant heating. Find qualified professionals through the Calgary Construction Network at calgaryconstructionnetwork.com.
