Garage Furnace Btu Calculator

A 30 x 40 pole barn with 14 foot average ceilings will have 30x40x14 16 800 cubic feet of space to heat.

Garage furnace btu calculator.

Just multiple the btus by 0 92 to find the number of watts needed. Take the guesswork out of garage heater sizing. Our free garage heater calculator takes the guesswork out of selecting a garage heater. Your heater size depends on the garage s square footage ceiling height and insulation so don t guess.

Calculate the number of british thermal units required to raise the temperature inside the garage to the desired temperature. Taylor you can calculate btu requirements to insure purchasing a sufficient garage heater. Insulation volume temperature rise 1 6 btu. Divide your total square footage by 200 and then multiply your answer by 9 000 to determine the btu requirements for an uninsulated garage.

Since electric garage heaters are rated according to their wattage and gas garage heaters are rates according to btus you can estimate the required size of a gas heater by multiplying by the wattage by 3 41. To calculate the size unit heater required for your space use the following formula. Calculate the cubic footage of the space to be heated by multiplying building length x width x ceiling height. Most residential garages require heaters with a capacity of 30 000 or 45 000 btu.

One watt is equal to about 3 41 btus per hour. It is approximately the energy needed to heat one pound of water by 1 degree fahrenheit. 1 watt is approximately 3 412 btu per hour. More importantly 0 29 btus per watt.

And don t oversize your heater especially if you intend to leave it on even at a reduced temperature all winter. For this step you ll need to determine how well the garage is. If you took one pound of water and raised its temperature by one degree fahrenheit you would have used one btu of energy. Given all the different options available for heaters space vented gas console and more narrowing down the choices can be a great way to ensure that you are choosing the best option.

Multiply by 6 000 instead of 9 000 if your garage is insulated. Btu or british thermal unit is a unit used to measure energy requirements for thermal regulation. The british thermal unit or btu is an energy unit. 1 btu 1 055 joules 252 calories 0 293 watt hour or the energy released by burning one match.

5280 x 3 41 18 005 btus.
