How Does an Energy Efficient Propane Furnace Work?

Taking into account that a typical homeowner spends about 30 to 50 percent of their energy expenditures on heating it is an area that most would love to lower as much as possible. A high-energy efficient gas furnace can do just that for you by reducing the high use of energy.

• Understand the difference between a standard furnace and a high efficiency furnace. Where standard furnaces use gas to generate heat and then blow it through ducts in the home and the exhaust fumes are vented out through a flue or chimney efficiency furnaces do not.


• Use of a secondary chamber within an efficiency furnace captures those exhaust gases and condenses those by products and makes a liquid and extracts any heat left. That heat then gets moved to a second heat exchanger and supplies the primary heat exchanger in heating the air going to the ducts. What little waste is then left is exhausted through a flue.


• Compare efficiency furnaces with standard furnaces by using the annual fuel utilization efficiency (AFUE) ratings. These ratings show what percentage of gas the furnace uses is transferred into actual usable heat. These ratings show that standard furnaces have a minimum rating of 78 percent and high efficiency models have ratings of 90-97 percent.


• Saving money and benefiting the global ecosystems can be achieved with one of the high-efficiency furnaces. It is possible to save around 20-30 percent on your energy costs in your home or business by installing a high efficiency furnace. It will also reduce your carbon dioxide emissions, slow global warming and the detrimental health effects from that to our ecosystems.
