Garage Heater Btu Calculator

You need a heater with at least a 21 780 btu output.

Garage heater btu calculator.

When you go to buy a heater you will see that the btus are listed as a guideline for the heating capacity and are usually broken down into different levels. To calculate the size unit heater required for your space use the following formula. Our free garage heater calculator takes the guesswork out of selecting a garage heater. If you took one pound of water and raised its temperature by one degree fahrenheit you would have used one btu of energy.

To get the square footage multiply the. Answer a few questions about your energy source and garage and the garage heater calculator free tool recommends models that will do the job. Measure the square footage of the floorspace. For example if your uninsulated garage is 484 square feet your formula is 484 200 x 9 000 or 21 780.

You can calculate btu requirements to insure purchasing a sufficient garage heater. Insulation volume temperature rise 1 6 btu. Up to 450 sq ft. One watt is equal to about 3 41 btus per hour.

Take the guesswork out of garage heater sizing. 2 enter the price of electricity in dollars. 5280 x 3 41 18 005 btus. For example if your cost for natural gas is 14 00 per 1 000 cubic feet then divide by 10 and enter 1 40 as your price per therm.

British thermal units or btus are a measurement of the energy required to raise the temperature of one pound of water by one degree. Insulated 1 car garage. 70 f inside 20 f outside. Just multiple the btus by 0 92 to find the number of watts needed.

50 f temperature rise 60 f temperature rise 70 f temperature rise. 1 enter the price of natural gas as the price per therm. A 30 x 40 pole barn with 14 foot average ceilings will have 30x40x14 16 800 cubic feet of space to heat. 1 car 10 ft ceiling.

70 f inside 0 f outside. More importantly 0 29 btus per watt. Find a heater with a btu output that matches your results. Fortunately the calculation for correctly sizing a heater is simple when you take accurate measurements.

1 car 8 ft ceiling. Calculate the cubic footage of the space to be heated by multiplying building length x width x ceiling height. Up to 450 sq ft. 70 f inside 10 f outside.

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. If your price for natural gas is based on per 1 000 cubic feet divide that number by 10 to enter above.
