Ottawa’s cold climate means that space heating accounts for up to 61% of the energy used in the average Ottawa home.
Boilers use gas or oil to provide space heating and hot water to your home. Boilers distribute heat using radiators or in-floor radiant heating, eliminating the need for pre-existing duct systems.
What to Look For
- Gas and oil boilers are subject to Canada’s Energy Efficiency Regulations, which sets minimum performance standards for their energy efficiency. All boilers sold in Canada are energy efficient.
- Check the Annual Fuel Utilization Efficiency (AFUE) rating, the minimum should be between 82 and 84 per cent.
- Replacing your oil boiler? Consider switching to a natural gas boiler which tends to produce less waste and fewer harmful emissions.
Things to Consider
- Insulate the hot water pipes.
- Empty or “bleed” the air from the radiators once or twice a year so that they can fill fully with water.
- Vacuum the radiators to prevent dirt and dust from building up.
- Ensure that the level of water in the expansion tank is correct.
- Before you replace your boiler, get a home energy evaluation, which can help you understand how your home currently uses energy.
- Check with your municipality, utility or retailer to see if there are any rebates on boilers available.
