Depending upon the furnace between 5 percent and 30.
Which is more efficient propane or electric furnace.
It may have an annual fuel utilization efficiency afue rating as high as 100 percent.
Environmental impact of propane and electric heat.
To start propane is a primary energy source whereas electricity is secondary that is to say propane can be used as is and electricity can only be used once it s been created by another energy source.
Assuming you compare the most efficient furnace of each type you can adjust the relative heat production of the two forms of heating fuel.
Propane heat is more economical and more efficient than electric heat.
Comparing brand new furnaces you should expect to get a fuel efficiency of between 89 and 98 percent for propane and between 80 and 90 percent for heating oil.
The average lifespan of a propane furnace is about 20 years while electric heat pumps last about 14 years.
Over time propane furnaces also maintain their efficiency better than electric heat pump systems.
Heat and energy efficiency.
Generally the gas units heat up the home faster than electric and they tend to be more efficient in really cold temperatures because gas systems will achieve a higher temperature than electric units in extreme temperatures.
Gas furnace ratings range from 55 to 97 percent.
Virtually anything in your house restaurant or building that can run on electricity can run on propane.
Durability a factor that influences the overall cost of each type of heating is durability as well propane furnaces lasting on average up to 10 years longer than electric heat pumps.
However the cost of a propane fueled home is actually less than the cost of a home with electric heat.
This means that it takes more energy to create electricity which can affect its cleanliness efficiency and cost.
With fossil fuels there is always a loss.
