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.Continue Reading
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 >
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 >
The number of BTUs needed to cool a room varies greatly and is dependent on the size of the room. To determine specifically how many BTUs are needed, measure the area of the room, and review a chart or calculator.Full Answer >
The size of a boiler depends on the size of the home and local climate, but a 2,000-square-foot home in an area with a moderate climate could use a boiler rated at 70,000 BTUs, according to BobVila.com. However, choosing the right size requires weighing a number of factors.Full Answer >
