Heat Pump Water Heater Rebates in Ontario

In short

Ontario's Home Renovation Savings Program pays $500 for replacing a water heater with an ENERGY STAR certified heat pump water heater. The rebate requires a home energy assessment before work starts and at least two qualifying upgrades, such as insulation or air sealing, so a water heater swap on its own does not qualify. It best suits homes with an electric tank and an unfinished basement.

How much you can get

Heat pump water heater replacing a natural gas, electric, propane or oil water heater $500
Heat pump water heater installed as the only upgrade No rebate: at least two upgrades are required
Home energy assessments (initial and follow-up) $600 back after successful completion
Bonus for completing three qualifying upgrades $500
Gas tank or gas tankless replacement No rebate
Insulation, windows and doors, air sealing (the usual second upgrade) See the program page

Who qualifies

The homeowner applies, including for a house that is rented out.
Eligible housing is a detached or semi-detached house, a row or townhome, or a mobile home on a permanent foundation.
The household is an Enbridge Gas customer heating with a gas furnace or boiler, or is connected to the Ontario grid and heats with electricity, propane, oil or wood.
A registered energy advisor completes the initial home energy assessment before any work begins.
At least two upgrades from the assessment path are completed in the project.
The new unit is an ENERGY STAR certified domestic heat pump water heater that replaces an existing water heater.
The same advisor carries out the follow-up assessment after the installation.

The amount is small and the conditions are specific, so it helps to decide whether this kind of water heater suits your house before thinking about the rebate. Both halves are below.

Is a heat pump water heater an eligible measure, and for how much?

Yes: it is listed on the Home Renovation Savings Program site at $500, under the upgrades that require a home energy assessment. The program lists it for all three customer groups. Whether you are replacing a natural gas water heater, an electric one, or a propane or oil one, the new unit must be an ENERGY STAR certified domestic heat pump water heater.

The amount does not change with the fuel you are leaving. That is unlike the space-heating heat pump rebate, which pays more to homes without gas.

Why a water heater swap alone does not qualify

The assessment path has a floor of two upgrades, and its steps are fixed.

Book an initial home energy assessment with a registered energy advisor before any work begins.
Choose at least two of the upgrades recommended in the report.
Have your contractor complete them.
Have the same advisor return for a follow-up assessment.
Receive the rebate once the advisor submits the paperwork: the program quotes 60 days by cheque or 30 days by e-transfer.

The other upgrades on this path are insulation, windows and doors, and air sealing. The program returns $600 toward the two assessments after successful completion and adds $500 when three qualifying upgrades are done.

So the decision rule is simple. If you were already planning attic insulation or air sealing, adding the water heater makes it a two-upgrade project and the $500 is real. If the tank is leaking today and nothing else is planned, replace the tank and do not count on a rebate, because work begun before the initial assessment falls outside the program.

Which homes a heat pump water heater suits

It suits a house with an electric tank today and an unfinished basement with a floor drain. The unit pulls heat out of the air around it, so it needs air volume, and it cools and dehumidifies the room it sits in.

Space: common models ask for roughly 700 cubic feet of surrounding air, or ducting; the installation manual sets the figure.
Height: the heat pump sits on top of the tank, so the unit is taller than the tank it replaces. Low basements in older Hamilton and Toronto houses can rule it out.
Power: an existing electric tank already has a 240-volt circuit. A house leaving a gas tank needs a new circuit, which is electrical work under the ESA, and the gas line capped by a licensed gas technician.
Drain: it produces condensate, like a dehumidifier, and needs a floor drain or a condensate pump.
Recovery: in heat pump mode it reheats more slowly than a gas tank, which larger families notice. Hybrid mode uses the electric elements to catch up.
Sound and temperature: it runs a fan and a compressor and leaves the room a few degrees cooler, which is welcome in July and less so beside a finished rec room in January.

Rural homes on electric water heating, around Campbellville, Carlisle and rural Caledon, are the strongest case, because they are replacing the most expensive way to heat water. A gas-heated house in town with a gas tank that is cheap to run is the weakest.

What it costs against a standard tank

A straight tank-for-tank swap typically runs $1,200–$2,500 installed. We do not publish a heat pump water heater range, because the unit is only part of the job. The quote moves with:

Tank size, and whether the model needs ducting.
A new 240-volt circuit and spare panel capacity, if you are leaving gas.
A condensate drain or pump.
Removing the old vent and capping the gas line.
A rental contract buyout, if the current tank is rented.

Hard water across Halton and Hamilton shortens the life of any tank, so the anode rod and an annual flush matter here as much as on a conventional unit. General price bands for water heaters are on our pricing page.

Installation details are on the heat pump water heater service page, and the payback question is worked through in is a heat pump water heater worth it. Other programs are covered under water heater rebates and on the Ontario rebates hub. To have the basement checked for space, drain and power, get in touch.

How ZK Mechanical helps

Check the basement for air volume, ceiling height, drain and circuit before recommending the unit.
Tell you when a standard tank is the better buy for your house.
Coordinate timing with your energy advisor so no work starts ahead of the initial assessment.
Supply the model number and ENERGY STAR documentation the advisor needs for the file.
Cap the gas line and remove the old venting with a TSSA-licensed gas technician when the old tank was gas.

Frequently asked questions

Can I get the $500 if I only replace the water heater?

No. The heat pump water heater is on the path that starts with a home energy assessment and requires at least two upgrades, so it has to be paired with insulation, windows and doors, or air sealing. A water heater replaced by itself, or before the initial assessment, is not eligible for the $500.

Does replacing a gas water heater qualify, or only an electric one?

Both qualify, and so does a propane or oil water heater. The program lists the measure separately for natural gas customers, electrically heated homes, and homes on propane or oil, each at $500. In every case the replacement has to be an ENERGY STAR certified domestic heat pump water heater.

Do I have to use a specific contractor for the water heater?

The assessment path tells homeowners to have their preferred contractor complete the work, which differs from the heat pump rebate and its list of participating HVAC contractors. The energy advisor is the fixed part: the assessments must be done by a registered energy advisor reached through the program's list of service organizations. Read the terms and conditions before booking.

Will a heat pump water heater work in a cold basement?

It works, with a penalty. The cooler the surrounding air, the less heat the unit can pull from it, and each model lists a minimum air temperature below which the electric elements take over. A basement that stays near room temperature all winter is fine. An unheated crawl space or garage in Ontario is a poor location.

How long does the rebate take to arrive?

The program says rebates are sent after the follow-up assessment is finished and the registered energy advisor has submitted all the required documents. From that point it quotes 60 days by mail if you chose a cheque, or 30 days if you chose Interac e-Transfer. Delays usually trace back to missing paperwork, so keep the invoice and model details together.
