80000 Btu Furnace Square Footage

Another point worth mentioning.

80000 btu furnace square footage.

That means the furnace will produce 80 000 btu of heat. Consult an hvac expert for. 2 000 square feet x 40 btus 80 000 btu output required. A more efficient furnace will output more btus of heat than a less efficient furnace with the same btu rating.

Thanks to the equation we know we need 80 000 btus of heat. For instance a furnace with 80 000 btu input and an 80 efficiency rating will only produce 64 000 btus. If your house measures between 2 035 and 2 070 square feet a 80 000 btu per hour unit is best and more than 3 390 square feet requires a 120 000 btu per hour furnace. For example if your uninsulated garage is 484 square feet your formula is 484 200 x 9 000 or 21 780.

You need a heater with at least a 21 780 btu output. Different furnaces of the same input btu have different efficiencies measured in percentages. 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. Our btu calculator is the best there is for fireplaces stoves and inserts.

We need something stronger. If that same furnace has an efficiency of 95 the furnace will produce 95 000 btu of heat. But there are also rule of thumb estimations you can use to pick a furnace size for your home. Btu charts furnace output and air conditioner size for a bungalow bungalow area sq ft furnace output btu hr air conditioner size ton built after year 1980 built before year 1980 built after year 1980 built before year 1980 up to readmore.

For cooler climates a very broad estimate of furnace sizing is to select one that generates 40 to. But before we buy an 80 000 btu furnace there s furnace efficiency to consider as well. For instance if you live in a home that s 800 square feet you ll need a unit with 16 000 btus. For example a furnace with an input btu can have an efficiency of 80.
