Quick quiz: water heater in Ottawa

Questions about Ottawa, from the data behind this page. Tap an answer to see why.

1. Rebates in Ottawa often depend on the utility. Which one do we use for Ottawa?

Hydro Ottawa is the utility we use for Ottawa. Rebates often depend on who supplies your power or gas, so check yours first.

2. What is a typical January night low in Ottawa?

Our weather sample for Ottawa (2015-2024) shows an average January low of -13 °C. Cold-climate heat pumps are tested at low temperatures, so check the rating at your coldest days, not just the average.

3. Out of 100 homes in Ottawa, about how many are rented?

The 2021 Census counts 147,025 renter households out of 407,250 in Ottawa. Many rebates go to owners, and some programs have separate rules for landlords and tenants.

The post-audit must be scheduled by November 30, 2026 and completed by December 31, 2026, or within 180 days of your first assessment, whichever comes first.

Where the unit sits

A heat pump water heater draws heat from the air around it, so a cold utility room changes how it performs. Ottawa's January average low is -13.2°C, and a basement in an older house can be cool. The program does not set a location rule, so ask the installer where the unit will go and how it will be vented or ducted.

Pairing with attic work

Of Ottawa's 407,250 households, 44% live in homes built before 1981 and 64,225 are owner-occupied detached houses of that age. For those, attic insulation is a natural partner. The attic can pay up to $1,500 in the assessment stream, and together with the $500 water heater it clears the two-measure minimum.

Fuel and the replaced tank

For gas homes, the old tank has to be a natural gas water heater. For oil, propane, wood or electrically heated homes, the old tank can be oil, propane or electric. Check which category your home and tank fall into before the installer quotes.

Better Homes Ottawa

The City's loan is repaid on the property tax bill and excludes gas upgrades. We recorded up to the lesser of $125,000 or 10% of assessed value over 20 years, with 0% for households under income thresholds. Confirm current terms with the City.

When the house has tenants or a suite

The program requires you to own the home, and where an owner has tenants the owner must apply. In Ottawa, 36% of households rent. A house built as a single dwelling that later gained a secondary suite is eligible if the audit covers the whole home and a central heating system serves it. A house built as a multi-family dwelling is not eligible.

The calendar, in order

Sequence the steps: first assessment, then installation, then follow-up. The post-audit has to be scheduled by November 30, 2026 and completed by December 31, 2026, or within 180 days of the first assessment, whichever comes first. A water heater can be installed in a day, but the follow-up visit depends on the advisor's calendar, so book both early.

How to claim in Ottawa

  1. Confirm your home is an eligible type and find out what fuel heats it.
  2. Book the first home energy assessment with a registered energy advisor before any work starts.
  3. Choose at least one more upgrade to pair with the water heater, such as insulation, windows or air sealing.
  4. Choose an ENERGY STAR certified heat pump water heater from NRCan's list and have a licensed, trained professional install it.
  5. Keep invoices and your property tax bill, and book the follow-up assessment before the December 31, 2026 deadline.
