water heater on demand

If your furnace breaks down, you may decide to invest in a replacement unit rather than pay to have your old appliance repaired. Here’s a look at why you should consider upgrading to a high-efficiency furnace.

The features of a high-efficiency furnace

A furnace’s efficiency is measured by its annual fuel utilization efficiency (AFUE) rating. Older furnaces generally have an AFUE rating of 65 to 70. This means only 65 to 70 per cent of the fuel used to run your furnace is converted into heat for your home. In contrast, a modern furnace must have an AFUE rating of 90 to 98.5 to be considered highefficiency. With this type of appliance, very little energy is lost in the process of heating your home.

Additionally, a modern furnace boasts the following qualities:

  • Electronic ignition. Instead of a pilot light that burns at all times, these furnaces use an electronic ignition to turn on when heat is required.
  • Two-stage heating. With two levels of heat output, a modern furnace can save energy by running on a low setting most of the time and increasing to a higher setting when the temperature drops significantly.
  • Variable airflow. A variable speed heating system allows high-efficiency furnaces to precisely control the indoor air temperature and conserve energy by regulating air distribution.

The benefits of a high-efficiency furnace

Here are four more reasons to consider upgrading to a high-efficiency furnace:

  • You’ll save on your utility bills. A furnace with a high AFUE rating and an electronic ignition can reduce your heating bill by up to 45 per cent every winter.
  • It’ll last longer. High-efficiency furnaces often have a system to remove excess moisture in the heat exchanger. This is just one of the features that can give a highefficiency furnace a longer lifespan than other models if it’s well maintained.
  • It’s better for the environment. Since it uses less fuel than an older furnace would, a high-efficiency model produces fewer emissions and helps conserve natural resources.
  • Your family will be safer. High-efficiency furnaces don’t run for extended periods of time and they do a better job of regulating airflow. As a result, the combustion process is safer. In addition, some models have vents that further improve indoor air quality.
