Twelve thousand BTUs (British Thermal Units) per hour are equal to 1 ton of cooling capacity. A BTU is the basic measurement of thermal energy.Know More
A British thermal unit is defined as the amount of heat needed to raise the temperature of 1 pound of water by 1 degree Fahrenheit to a specified temperature. Many appliances have BTU ratings, which are often in the thousands. One BTU is an extremely small unit of measurement. Its energy power is about the same as burning one match.
One single BTU can also be expressed as being equal to between 1,054.35 and 1,059.67 joules, another common energy measurement. One BTU is also equal to 252 calories. A calorie is the amount of heat needed to raised 1 gram of water by 1.8 degrees Fahrenheit. One BTU is also equal to about 0.000293 Kilowatt hours.Learn more about Heating & Cooling
According to the Energy Star program for energy efficiency, a 1,100 square foot room requires around 21,000 BTUs per hour to cool. The number of BTUs (or British Thermal Units) required for an air conditioner unit to cool a room depends on many factors beyond the room's size.Full Answer >
A 10-ton air conditioning unit is a cooling system capable of removing 120,000 British thermal units of heat per hour from the air in the building to which it is attached. In this system of measurement, 1 ton is equal to 12,000 BTUs of heat extraction per hour.Full Answer >
The size of a garage, as well as its geographic location, determines how many BTUs a furnace needs to heat the space. The general range is from 25 BTUs per square foot of space in moderate climates to 45 BTUs per square foot in cooler climates.Full Answer >
Many factors determine the number of British thermal units needed to heat a house, but in a moderate climate with a high-efficiency furnace, a 2,000 square foot home requires a 50,000 to 60,000-BTU furnace output. The general rule of thumb is that furnaces need to provide 25 to 30 BTU output per square foot in moderate climates and 40 BTU output per square foot in colder regions.Full Answer >
