How Heat Pump Water Heaters Work in an Ontario Home
Water heating is one of the quieter energy uses in a house, but it runs every day, every season. A heat pump water heater, sometimes called a hybrid water heater, takes a different approach from a standard electric tank. Here is how it works, where it fits, and what to know about the rebate that is currently listed.
It moves heat instead of making it
A regular electric water heater turns electricity directly into heat. A heat pump water heater works more like a refrigerator in reverse. According to Natural Resources Canada (NRCan), the technology “does not generate heat directly.” Instead, it pulls heat from the surrounding air, often in a basement or utility room, and transfers it into the water in the tank.
Because moving heat takes less electricity than creating it, NRCan says ENERGY STAR certified heat pump water heaters are much more efficient than standard electric models. Your actual results will depend on your home, your hot water use and your electricity price plan.
What to expect from the equipment
Vivion installs hybrid heat pump water heaters from Rheem, A.O. Smith, Bradford White, John Wood and Midea. Tank sizes typically run from about 40 to 80 gallons. Some Rheem models include leak detection with automatic shut-off, which is a handy feature if the tank sits in a finished basement. Tank size is confirmed during your consultation.
Where it fits best
Since the unit draws heat from the air around it, location matters. NRCan notes the air can come from a basement, a utility room or, sometimes, the outdoors. It also points out that these units can help take the edge off summer air conditioning needs, but are less helpful in winter, when you are paying to heat the house. In other words, a heat pump water heater can slightly cool the room it sits in. That is worth thinking about when choosing a spot.
What it can mean for your hydro bill
Water heating is steady, everyday electricity use, so a more efficient unit can ease it. We can’t promise a savings figure, because it depends on how much hot water your household uses and when. If you want to see how your own numbers might look, try the Vivion Saving Calculator. Any result is an estimate, not a guarantee.
The Home Renovation Savings rebate
The Home Renovation Savings program lists a $500 rebate for qualified heat pump water heaters. According to Save on Energy, the water heater must be an ENERGY STAR certified model. On the program website it appears in the “do two or more upgrades” group, which starts with a home energy assessment. No end date is shown on those pages at the time of writing, so check the official site for the latest details. Eligibility depends on program rules – we can help check during your consultation.
Is a heat pump water heater right for your home?
A few questions can help you decide:
- Is there a basement or utility room where the unit could sit?
- How much hot water does your household use day to day?
- Are you planning other upgrades, like a heat pump for heating and cooling, that could be done together?
- Would you like leak detection with automatic shut-off on the tank?
Water heater installation should always be done by a licensed professional, so it is best not to attempt it yourself.
