In many cases furnace selection is largely dependent on fuel availability.
Is my roof furnace gas or electric.
This is mostly due to the simplicity of the design.
These systems combine both heating and cooling capabilities eliminating the need for a separate furnace indoors.
Should my furnace flue pipe go through the roof or the side of the house.
Both systems use a fan to force air through the heat exchanger or electric element which heats up as it passes through.
Gas is cheaper than electricity in most cases which makes furnaces more cost effective than electric heat pumps in areas that experience colder temperatures.
Forced warm air heating can operate using gas or electricity.
In these instances homeowners are limited to propane fuel oil or electric furnaces.
Or this pipe could also be a 2 4 inch white pvc pipe.
You can use a couple of methods.
There are fewer moving parts no vents and no burner.
This allows your furnace to get more heat out of the gas that it consumes.
Packaged units may be either electric or gas and combine all system components into one cabinet which is typically found on a slab next to your home or on the roof.
Both oil and propane require fuel storage tanks that are expensive to install and maintain.
Natural gas is the most popular fuel but the required piping infrastructure is not available in all areas of the country.
An electric furnace is generally quieter than a gas furnace.
This makes for a quieter furnace overall.
This is the exha.
Gas furnaces are not always more efficient than heat pumps however.
Gas furnaces are not necessarily noisy but they do make a loud rushing sound at the time that they start up and the burner ignites.
