Is electric or hydronic in-floor heating better for a Vancouver home renovation?

For most Vancouver home renovations, electric radiant heating is the better choice — it is significantly less expensive to install, easier to retrofit into existing floors, and well-suited to the room-by-room approach that renovation projects typically require. Hydronic (water-based) radiant heating is more energy-efficient for whole-house heating but involves major infrastructure and is primarily practical in new construction or complete gut renovations.

Electric radiant heating uses thin heating cables or pre-wired mats installed directly under the flooring surface. The mats are typically embedded in a thin layer of thin-set mortar or self-leveling compound, adding only about 1/8 to 1/4 inch of floor height. Installation is relatively straightforward for experienced contractors — the mat or cable is laid out on the subfloor, embedded in thin-set, and connected to a dedicated electrical circuit with a programmable thermostat. Electric radiant heating costs approximately $8–$15 per square foot installed for the heating system itself, plus the cost of your chosen flooring on top. A heated bathroom floor (40–60 square feet) typically runs $500–$1,000 for the heating system plus installation labour of $300–$600. A heated kitchen or living area (150–300 square feet) costs $1,500–$4,500 for the system and installation. Operating costs in Metro Vancouver run approximately $0.30–$0.60 per square foot per month during the heating season (October through March), depending on BC Hydro rates and usage patterns.

Electric systems excel as supplemental heating — warming specific rooms or zones where bare feet meet cold floors, such as bathrooms, kitchens, entryways, and basement living areas. In Metro Vancouver's mild marine climate, where winter temperatures rarely drop below -5 degrees Celsius, electric radiant heating can serve as the primary heat source in well-insulated rooms, though most homes use it to complement their main heating system. The programmable thermostat allows you to schedule heating around your daily routine — warm floors when you wake up and get home from work, reduced output during the day and overnight.

Hydronic radiant heating circulates warm water through PEX tubing embedded in or under the floor. The water is heated by a boiler (natural gas, electric, or heat pump) and pumped through zones controlled by a manifold system. Hydronic systems are more energy-efficient than electric for heating large areas — they cost approximately 30–50% less to operate per square foot because heating water with a gas boiler or heat pump is more cost-effective than resistance electrical heating. However, the installation cost is dramatically higher. A whole-house hydronic radiant system costs $15–$25 per square foot installed including the boiler, manifold, PEX tubing, and controls — a 1,500-square-foot home might run $22,000–$37,000 for the complete system. Retrofitting hydronic tubing into existing floors requires either removing the existing flooring and subfloor to install tubing in the joist bays, or adding tubing above the existing subfloor in a thin-slab pour that raises the floor height by 1–2 inches, creating transition problems at doorways and stairs.

The practical reality for renovation projects is that hydronic systems are rarely worth the disruption and cost unless you are already planning a major structural renovation — removing the existing floor system, replacing the subfloor, or doing a complete basement finishing project from bare concrete. If you are renovating specific rooms and want warm floors, electric mats are the logical choice. If you are building a new home or doing a complete gut renovation and want radiant heating throughout, hydronic is the more efficient long-term investment.

Permits and inspections are required for both systems in Metro Vancouver. Electric radiant heating with hardwired connections requires an electrical permit and inspection by Technical Safety BC. A TSBC-certified electrician must make the electrical connections — do not attempt to wire the thermostat and circuit yourself. Hydronic systems may require plumbing and mechanical permits depending on the scope, particularly if a new boiler is being installed. Gas-fired boilers require a gas fitting permit and Technical Safety BC inspection.

Regarding flooring compatibility, both electric and hydronic systems work well under tile (the best conductor), engineered hardwood, and LVP/SPC vinyl. Never install either system under solid hardwood — the heat causes drying, shrinkage, and permanent damage. Thick carpet over either system significantly reduces efficiency. When choosing your flooring, confirm the product is rated for radiant heat and note the maximum surface temperature specification — most require staying below 80–85 degrees Fahrenheit at the floor surface.

For a heated floor renovation in your Vancouver home, start by identifying which rooms you want heated and consult with both a flooring contractor and an electrician (or mechanical contractor for hydronic).
