In this type of furnace 20 of the energy produced by natural gas is expelled as exhaust.
High efficiency gas furnace vs regular gas furnace.
High efficiency furnaces offer 90 or more afue.
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.
These days 95 afue is a common rating among new gas powered furnaces.
To achieve the term high efficiency within the industry a furnace must be 90 efficient within it s gas usage.
The primary difference is the manner in which they are vented.
If you live in an area where electricity costs less than gas then a heat pump is also the better option.
If you live in the south where winter temperatures may only reach 40 to 60 degrees then a heat pump is the best fit for your home.
Both have smart phone compatible thermostat options.
Most of the reasons you would choose a heat pump vs.
High efficiency furnaces are those that are at least 90 percent efficient.
But that s a limited view of what efficiencies can be gained and what benefits can be provided.
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.
A standard efficiency furnace provides 80 annual fuel utilization efficiency afue.
Gas furnace come down to where you live.
Since the heat lost through the flue of a high efficiency condensing furnace is a lot less than the heat lost through the flue on a standard efficiency furnace the steam is much cooler on the high efficiency condensing furnaces.
