Today’s furnace companies in Calgary sell units with a variety of AFUE ratings. When choosing your home furnace here in Calgary, one of the most important factors to consider is energy efficiency. A furnace’s Annual Fuel Utilization Efficiency (AFUE) is a measure, expressed as a percentage, of how efficiently a furnace uses the fuel it burns to produce heat.
High-efficiency gas furnaces are defined as those with an AFUE rating of at least 90%. Some are rated as high as 98.5%. However, some homeowners have old model furnaces that may have AFUE ratings as low as 60%. This means that only 60% of the fuel going into the furnace becomes heat used to warm your home. The other 40% is simply wasted fuel.
Any furnace you buy is meant to do two things:
What differentiates one furnace from another is how this heat is produced and how it’s distributed. The more efficient your furnace is at these two things, the more economical your heating system is, meaning the fewer dollars required to heat your home. Studies show that as much as 50% of your home’s total energy costs go toward heating. So trading up from an outdated 60% or 70% AFUE furnace to a 90%-98.5% AFUE unit represents a significant saving, especially over the multiple-decade life expectancy of today’s new furnace models.
A couple of technological developments in furnace design are responsible for the energy savings high-efficiency furnaces provide:
The upfront cost of buying a high-efficiency furnace makes sense any way you look at it. Start saving on energy costs from day one and for many years after. Of all the furnace companies in Calgary, Wiehler Plumbing and Heating is rated #1. We’re here to keep your family warm 24 hours a day.
