About Energy Efficient Propane Furnaces

Energy bills are a major expense in most households, and many people are recognizing propane furnaces as cost-effective alternatives. Propane is a portable, clean burning, and efficient fuel. These characteristics have made propane furnaces energy efficient, durable, and highly convenient. In addition, these furnaces are environment-friendly and do not give out any toxic emissions. Listed below are some of the major points you may want to consider before deciding on a propane furnace for your home.

Types of Propane Furnaces

Propane furnaces are available in three types:

  • Central propane furnaces are placed at a central location in a home, and provide heated air through ducts or vents. The venting systems in these furnaces can adapt to horizontal or vertical vents. Most of these furnaces have the highest efficiency ratings.
  • Combination propane furnaces use water heaters as the primary source of heat. Excess heat from the water heater is absorbed by an air handler system. This heat, which would have been wasted in an ordinary water heater, is used to warm the house through ducts or vents. These units provide heating for the living space as well as the water supply.
  • Wall furnaces are usually used in small structures such as mobile homes. These furnaces have vents and include wiring. They are easy to install, and are safe and durable.

Energy Efficiency

Most propane furnaces are equipped with vent dampers. These dampers close when the desired temperature has been reached. Propane furnaces also have electronic ignition systems, which activate the burner only when there is need for heat. These furnaces produce better heating results as compared to electric furnaces, by producing heat faster and retaining it longer. The heat is distributed more evenly as compared to electric furnaces. Propane furnaces have efficiency ratings around 95%, and cost 50% less British Thermal  Units (BTU) than electric furnaces.


Propane furnaces do not require electricity to operate. As a result, homes are kept warm even during power failures. These furnaces do not require the use of a chimney, unlike wood furnaces. The space requirements of most propane furnaces are also minimal. Some propane tanks can be installed outside a house and concealed by landscaping, or buried underneath the ground.


The initial setup and installation of a propane furnace may be a costly deal, especially if you have to install new pipes. However, when you consider the energy efficiency of propane furnaces, you will most probably be saving money in the long run. Also, propane furnaces are more durable, and require lesser maintenance as compared to other furnace types.


The average lifespan of a propane furnace is 15 to 20 years, which is almost double that of electric furnaces.

Environment Safety

As compared to other furnaces, propane furnaces do not emit any fumes, and as a result, the air is cleaner. The fact that they do not use wood adds to their environmental appeal, as well as ease of use.
