Gas furnaces are fueled by Natural Gas or Propane. They typically use the forced air style of heating, meaning the air is heated in the heat exchanger of the furnace itself and is then forced through the attached duct-work to the vents that feed the home.
Older types of gas-fired furnaces lose significant amounts of energy in the hot waste gases exhausted up the chimney. More modern high-efficiency furnaces condense the water vapor emitted as one of the products of consumption. This increases the efficiency of the system to over 90%.
Advantages of Gas Furnaces:
There are also some disadvantages when considering a gas furnace as well. Your cost of installation will increase if you don’t currently have a ventilation system, or natural gas lines. Both oil and propane require fuel storage tanks that require installation and maintenance. Gas furnaces emit a low level of carbon monoxide, so you must have a carbon monoxide detector running in your home and perform regular maintenance to ensure your unit is working properly.
When considering your home heating options, whether to go with an electric or gas furnace, there is also a third option, a heat pump. Electric heat pumps are more energy efficient than gas furnaces and require much less electricity to operate than electric furnaces.
