No matter how much you may want to postpone replacing your old furnace, there comes a time when you know it’s time for a new one. In this case, upgrading to a high efficiency gas furnace may just be the best option for you given its increased reliability and lifelong economical service. A high efficiency gas furnace is a great appliance that makes your home more comfortable, improves your home’s value, and can save you money on your gas bill every month.
How do you recognize a high efficiency gas furnace? Just like with any other type of furnace, you will have to check its AFUE rating, which should be between 90 and 95%. What is AFUE? AFUE stands for Annual Fuel Utilization Efficiency, and an AFUE rating of 90% means that your gas furnace uses 90% of the fuel to maintain the desired room temperature and turns 10% of the fuel into exhaust gases. Therefore, the higher the AFUE is, the more efficient your gas furnace will be. Your investment in a high efficiency gas furnace depends mainly on the AFUE rating, which should aim for maximum benefits with minimal losses.
Now that you know how to determine the difference between a high efficiency gas furnace and a less efficient one, you can continue to explore some of the features and technology behind efficient furnaces:
- The greatest feature of a high efficiency gas furnace is the electronic ignition technology designed to eliminate the use of the pilot light, a common component of standard forced-air furnaces. The electronic spark ignition saves energy as it gets activated only if and when the furnace is actually engaged, unlike the pilot light that is in a continuous burning mode. The pilot light is the major fuel wastage culprit in the case of conventional gas furnaces. Its replacement with an electronic ignition means a higher AFUE rating and therefore major savings for you.
- A high efficiency gas furnace benefits from an automatic vent damper that is designed to increase thermal efficiency by closing the fuel pipe and restricting use of fuel when the burner is not in activated. This is called pulse combustion technology and is a major contributor to the high AFUE rating of energy efficient gas furnaces.
- Air no longer circulates freely through the system with a high efficiency gas furnace. In fact, the air flow is induced and regulated, which improves the efficiency of gas furnaces and additionally makes combustion a safer process.
Upgrading to a high efficiency gas furnace is a great decision. Your new, more efficient furnace will last longer and offer you increased savings throughout its lifetime.
