Heat pump water heaters: how the $500 Ontario rebate works, and why it needs an energy assessment
Home Renovation Savings offers $500 for a heat pump water heater, but unlike a heat pump for heating, it needs an energy assessment first and at least two upgrades. Here is what the official pages say.
A heat pump can heat your home, and a different kind of heat pump can heat your water. In Home Renovation Savings, the Ontario program run by Enbridge Gas and Save on Energy, these two sit in different parts of the program with different rules. Here is what the official pages say today.
Two streams, two sets of rules
A heat pump for heating your home is in the no assessment stream. You do not need an energy assessment, but pre-approval is mandatory, and installations done before approval are not eligible.
A heat pump water heater is in the assessment stream. You need a home energy assessment before any work starts, and you must install at least two upgrades from that stream to get rebates.
What the water heater rebate pays
The rebate is $500. To qualify, you replace your existing domestic water heater with an ENERGY STAR certified domestic heat pump water heater. The program lists this for homes with a natural gas (Enbridge), electric, propane or oil water heater.
The other upgrades on the same list include attic, wall, foundation and exposed floor insulation, windows and doors, and air sealing. Complete three qualifying upgrades and you get an extra $500. There is also a $600 rebate toward the cost of the assessments, paid after you finish the program. It is paid once per participant, per home.
The steps, in order
- Book an initial assessment with a Service Organization before you start any work. It takes about two hours.
- Get your custom report and choose at least two recommended upgrades.
- Have the work done. A heat pump water heater must be installed by a professional contractor.
- Book a follow-up assessment with the same registered energy advisor. It takes about an hour.
- Get your rebates: within 60 days by cheque, or within 30 days by Interac e-Transfer.
If you have already started the work, the program says you are not eligible for these bundled rebates. You may still be eligible for a heat pump, which does not need an assessment.
Who can apply
- You must own your home. Where an owner has tenants, the owner must apply.
- Single detached, semi-detached, row or townhomes, and mobile homes on a permanent foundation qualify. Stacked townhomes do not.
- You heat mainly with a natural gas furnace or boiler as an Enbridge Gas customer, or you are on the Ontario grid and heat with electricity, propane, oil or wood.
What the pages do not say
The official pages do not say whether a heat pump for heating counts as one of your two assessment-stream upgrades. It is listed separately, with its own application. If you plan both, ask the program through its help and support page.
The federal rebate is separate
The federal National Heat Pump Rebate page does not mention water heaters. It covers heat pump systems that can heat your entire home. Canada.ca says installs from November 1, 2026 may qualify, for $2,000 above the median income or up to $10,000 at or below it, with applications opening online in early 2027. It also says the details may still change.
