60000 Btu Furnace Square Footage

Furnaces are rated on their btus of energy consumption not their btus of energy output.

On the other hand the colder zone 5 climates of the northeast upper midwest and pacific northwest demand 50 60 btus per square foot for maximum efficiency. But before we buy an 80 000 btu furnace there s furnace efficiency to consider as well. With these numbers you can calculate your furnace btu.

A 60 000 btu furnace will adequately heat most mid size family homes in zone 1 and zone 2. For example if a furnace is rated at 100 000 btus and is 80 efficient then the heat output will be 80 000 btus 100 000 x 8. A mid sized home of 2 000 square feet would need approximately 50 000 to 60 000 btu to heat it properly. For this example using an 80 efficient furnace the 1900 square foot home above would require a 90 000 btu input furnace that produces 72 000 btu s of heating which is close enough to the 76 000 btu s required using the climate heating factor.
