How many btus to heat a attic.

For example if you re trying to heat or cool 1 000 square feet you would multiply 1 000 by 20 and get 20 000 btus per hour. Simplified a single btu is more or less equal to the amount of heat and or energy produced by burning a single wooden match from end to end. 1 btu is the energy needed to heat 1 pound of water by 1 fahrenheit. What is a btu.

Calculating the number of btus needed to heat an area in terms of heating and cooling system the underlying calculation is how much you want to add or remove from the air inside a building. How to find how many btus your furnace should be. A british thermal unit btu is the measure of energy required to heat 1 pound of water 1 degree fahrenheit. One is roughly equal to 1 055 joules.

1 btu is the equivalent of 1 055 joules or 293 watts. The british thermal unit or btu is an energy unit. It is approximately the energy needed to heat one pound of water by 1 degree fahrenheit. We often refer to the british thermal unit as a btu but the rating is actually the btus per hour or btu h.

This is the standard measurement of heat output needed to heat any structure therefore can measure radiator power. 1 btu 1 055 joules 252 calories 0 293 watt hour or the energy released by burning one match. Ridge and soffit vents are also helpful for venting hot air and keeping an attic cool but you ll need a little extra help as this method alone probably won t remove enough heat to keep the space comfortable enough to live in. A standard 1 500 watt electric heater produces 5 115 1 500 times 3 41 btu per hour.

Purchase one or more ceramic heaters with safety switches or electric baseboards that provide the determined amount of btu required to heat the attic bedroom to the desired temperature. A btu or british thermal unit is an approximation of the amount of energy required to heat 1lb one pound of water from 39 f to 40 f and is roughly equal to 1 055 kjoules. Since mini splits last for a very long time getting the right btu capacity for the room size is essential. Once you have the total square footage just multiply that number by 20 to find how many btus per hour you d need to heat or cool the space.

This will ensure many years of comfort savings and efficiency. That might depend on a number of other variables such as square footage and climate but the starting point is how many degrees you want to move the inside temperature and how many btus are required to. Multiply the wattage of your unit by 3 41 per watt to calculate btu. 1 watt is approximately 3 412 btu per hour.
