Local rules and warranties

Under federal energy efficiency rules, an electric boiler sold in Canada must have an automatic water temperature adjustment device. Warranties often depend on installation to local fire and plumbing codes, and one manufacturer limits its tank warranty to 1 year when the heater goes into a building other than a single family home. Check the warranty terms and the installer's code compliance before you pay.

Winter demand and sizing

Winter runs from December to February here, and the heating load is highest in Montreal, Ottawa, Calgary and Toronto during that period. Ask sellers to size a boiler for your heat load in kilowatts (kW) or BTU, not only for the size of the house. For an electric tank, ask about the power in kW, for example 4,500 W on a 240 V connection.

Units and how it is quoted here

Listings show tanks in imperial gallons with litres in brackets (60 Gal Imp, 279 L), so write capacity in litres as well. Give the fuel type (natural gas or propane) and the voltage, and say which city the unit is for, since Toronto, Montreal, Vancouver, Calgary and Ottawa may have different delivery terms.

BlaBlaPrice is free for buyers. You describe the unit, capacity, fitting and site in your own words. Our AI asks for missing details, looks through sellers' websites and price lists in Canada, and shows the prices and businesses it found. Sellers reply in the chat with their own offer, and your contacts stay hidden until you choose to exchange them. Start with a request on BlaBlaPrice, or see heating and plumbing.
