  2. Feb 15, 2024 · Most Efficient Furnaces. The government has mandated that all natural gas furnaces sold here must have an Annual Fuel Utilization Efficiency (AFUE) of 95%+. A high-efficiency model means lower energy bills. However, the difference between a 95 and 98% AFUE furnace won’t be all that much.

  3. Feb 15, 2024 · The minimum efficiency furnace you can purchase in Canada is now 95% AFUE; Top high-efficiency furnaces on the market have AFUE of almost 99% AFUE; The BTU rating needs to be considered when choosing the right size of heating system.

  4. Oct 16, 2023 · A natural gas furnace is the most common, utilizing gas which is ignited in the burner, producing hot combustion gases that pass through a heat exchanger. This heat is then transferred to the air, which is circulated through the ductwork. Advantages: Cost-effective and widely available.

  5. What we see is that of the 15.2 million home furnaces in Canada over 7.1 million are fuelled by natural gas, over 4.5 million of which are now high eficiency models (eficiency of 90 per cent or greater).

  7. A furnace operates by using a fuel source — usually natural gas, propane, electricity, or oil — to produce heat. The heat produced flows through a ventilation system and warms the home. Let’s look at a natural gas furnace for a detailed example.

  8. Feb 25, 2020 · You can expect a furnace to last anywhere between 15 and 30 years, with most furnaces being replaced around the 17-year mark. It’s not unheard of for a furnace to run for more than 30 years, but in Canada, furnaces are steadily pumping out heat for at least 6 months of the year, and this generally means more wear and tear and a shorter lifespan.
