Furnace or boiler: what’s the energy-efficient choice?

According to Natural Resources Canada, space heating can represent up to 63% of a homeowner’s energy use. So, it’s no surprise that energy-efficiency is a top priority for many Canadians looking to upgrade their furnace or boiler.

Thanks to advances in technology, both systems can be an energy-efficient choice.

A heating and combi boiler system:

  • Works to heat your home and provide a constant supply of hot water.
  • Can be used to heat your pool or spa water, without coming into contact with your residential water supply.

A high-efficiency furnace:

  • Will have an AFUE rating of 92% and 98% energy efficient.
  • ENERGY START certified, forced-air, gas-fueled furnace units use 6% less energy on average than a standard model.
  • May qualify for government energy rebates and other incentives. Just ask your Home Comfort Advisor!
