Why Should You Upgrade to a High-Efficiency Gas Furnace?

Having a gas furnace in your home is essential for your comfort especially if you live in areas affected by the cold. And while it is working well, most people are reluctant to change it. Of course, the disruption of changing your furnace, as well as the cost are major factors, but even bearing these in mind, upgrading your old gas furnace to a new high-efficiency one can be worth it.

If you are already thinking about getting a new furnace, then the choice has already been made for you. There are many benefits to having a high-efficiency gas furnace, including:

  • It can save you a lot of money thanks to its efficiency
  • It is better for the environment
  • It will work perfectly, offering you the best quality heating

A high-efficiency gas furnace is specially designed to limit the amount of wastage, which has previously been impossible in older furnaces using some new technologies and techniques.

The AFUE (Annual Fuel Utilization Efficiency) is a measure of the efficiency of a furnace – based on the amount of gas exhausts, which are released. The measure is a percentage of the amount of energy used for heating – for example, a 75% AFUE means that 75% of the energy is used for heating and 25% wasted (through heat exhaust). A good AFUE furnace can have an AFUE of up to about 96%.

Through a reduction of wasted energy, your house will stay warmer with a lesser amount of energy used – and wasted, therefore reducing costs and lessening the impact on the environment.

There are some ways that a high-efficiency gas furnace can improve its efficiency, including:

Automatic Vent Damper

An automatic vent damper cuts the fuel pipe when it is not in use. This means that fuel will not be wasted, significantly increasing its efficiency. The auto vent damper is a relatively new technology, which is an excellent way of improving thermal efficiency.

Electronic Ignition Technology

Older gas furnaces used to use a pilot light, which was lit at all, times, wasting massive amounts of energy. The newer electronic ignition technology creates a spark, which is then used to ignite the gas, only when it is needed, and therefore cutting out on a massive amount of wasted energy.

Combustion

The newer high-efficiency gas furnace controls and induces the airflow so that it doesn’t freely circulate. This is not only useful in cutting out wastage and improving efficiency, but it also makes the whole system a lot safer.

When you are choosing a high-efficiency gas furnace the two most important factors that you should be thinking about (other than the cost) is having the highest efficiency rating as possible, and making sure that it is fitted correctly. After all, the more efficient your furnace, the lower your bills will be, and reduce the impact on the environment. Make sure that you get a responsible, professional company to fit your new furnace to avoid potential issues and maximize efficiency.
