Depending upon the furnace between 5 percent and 30.
Which is more efficient propane or electric furnace.
This means that it takes more energy to create electricity which can affect its cleanliness efficiency and cost.
Environmental impact of propane and electric heat.
Electricity is very efficient with nearly 100 percent of the electricity used converting to 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.
An electric furnace is the more efficient of the two.
Gas furnace ratings range from 55 to 97 percent.
Propane heat is more economical and more efficient than electric heat.
With fossil fuels there is always a loss.
Assuming you compare the most efficient furnace of each type you can adjust the relative heat production of the two forms of heating fuel.
Over time propane furnaces also maintain their efficiency better than electric heat pump systems.
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.
Heat and energy efficiency.
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.
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.
It may have an annual fuel utilization efficiency afue rating as high as 100 percent.
However the cost of a propane fueled home is actually less than the cost of a home with electric heat.
