So a 95 furnace is more efficient than an 80 furnace.
High efficiency gas furnace vs regular gas furnace.
High efficiency furnaces are those that are at least 90 percent efficient.
Given two furnaces of equal heat output rating usually measured in british thermal units the efficiency tells you how much heat goes into your house and how much goes up the furnace s chimney.
But that s a limited view of what efficiencies can be gained and what benefits can be provided.
To achieve the term high efficiency within the industry a furnace must be 90 efficient within it s gas usage.
Both will use both gas and electric power sources.
A standard efficiency furnace provides 80 annual fuel utilization efficiency afue.
In this type of furnace 20 of the energy produced by natural gas is expelled as exhaust.
Most of the reasons you would choose a heat pump vs.
The cost to have a gas furnace installed averages 4 500 and the cost to install an electric furnace runs about 4 000 but you could pay up to 10 000 or more for a high efficiency model of.
Both have smart phone compatible thermostat options.
Gas furnace come down to where you live.
Why choose a heat pump over a gas furnace.
High efficiency furnaces offer 90 or more afue.
If you live in an area where electricity costs less than gas then a heat pump is also the better option.
The primary difference is the manner in which they are vented.
