How it works
A heat pump water heater, also called a hybrid water heater, pulls heat out of the air around it and moves it into the water, like a fridge in reverse. Backup electric elements help when you use a lot of hot water at once.
Manufacturers rate them at about 3.5 to 4 times the efficiency of a standard electric tank. Rinnai lists its 50-gallon model at a UEF of 3.75; a typical standard electric tank is about 0.93.

Rebate
Ontario's Home Renovation Savings program pays $500 for an ENERGY STAR heat pump water heater that replaces your existing water heater. It is not a stand-alone rebate: you book a home energy assessment before any work, complete at least two upgrades from the advisor's report, then have a follow-up assessment. See our rebates page or the step-by-step in our heat pump guide.
Questions we get asked
Replacing an existing 240-volt electric tank costs $4,900 + HST for 50 gallons, $5,850 + HST for 65 gallons and $6,150 + HST for 80 gallons, including a thermostatic mixing valve. A condensate pump, if there is no floor drain within about 6 feet, is $250 extra. A drain pan under the heater is $100.
You can, but for most gas homes we recommend a power-vented gas tank instead, because gas is usually cheaper to run in Ontario. A heat pump water heater would also need a new 240-volt circuit run by an electrician.
Not if you are replacing an electric tank: we connect to the 240-volt supply that is already there. For a new location, an electrician runs the circuit first.
Yes. The unit makes water as it dries the air. A floor drain within about 6 feet is included in our price. If there is none, we add a condensate pump and run it to another drain for $250.
Rinnai and A.O. Smith cover the tank and parts for 10 years. We add a 1-year labour warranty on our installation.
Rinnai first, then Rheem and A.O. Smith. Rinnai has a new Wi-Fi model coming; ask us about it.

Yes, $500 through Ontario's Home Renovation Savings program, as part of a bundle with a home energy assessment and at least one other upgrade.
