13 Nov Advice: What are the cost savings when upgrading to a new high efficient furnace or boiler?

Natural draft furnaces are designed to be around 72% efficient on the day of manufacturing. This means that they actually use a minimum of 28% of the energy that they create to carry the byproducts of combustion through the convection currents, and up and out the flue or chimney.

This shows us that for every $100 spent on heating costs, $28 was wasted in carrying the exhaust up and out the chimney. This is coupled with a typical depreciation in efficiency over time caused by the buildup of carbon on the heat exchangers, preventing efficient heat transfer. A typical estimate has been set at about 1% per year. We think that estimate is a bit high, but if it’s anywhere close then most of these natural draft appliances are lucky to be running at 50% efficiency?!?! $50 of every $100 going right up the flue!!

For this reason, in Canada and other counties worldwide, we have decided to set a new standard which includes minimum efficiency ratings for new appliances. The requirement being a minimum efficiency of 92%.

With that said, there are even more efficient appliances currently sold which decrease the cost of running a new high efficient appliance even further.
