The British Thermal Unit or BTU represents amount of heat required to raise water warmth by a degree Fahrenheit.
The short form BTU stands for British Thermal Unit, a BTU is a unit that measures heat value or energy required. One thousand watts of power can be expressed as 3412 BTU in one hour. Energy expended in the form of heat is often measured by determining how many million BTU are required to raise certain amounts of water by given temperature difference. This information is used to determine the heating and cooling capacity of loads of buildings. Natural gas is also compared in BTU.
If you are using electric heat, it takes 6891 BTU/Hr to heat this room. If you are using gas, the heat transfer will be determined by which grade of gas you choose and what kind of efficiency your heater is. In case of air conditioners, BTU depends on the efficiency. If the air conditioner is more powerful, then higher the BTU.
A BTU measures how much heat or energy is given off when a certain amount of fuel is burnt. The energy in question can be in any form, such as electricity, natural gas, crude oil, fossil fuels and even firewood. Fuels like propane and natural gas are measured by btu.
An example would be putting a match to a piece of paper and watching it burn. In this case, the BTU being measured is actually fire or combustion. You are measuring the amount of BTU being released from the burning object.
The too few BTUs from a piece of wood does not remain in the air for very long, unlike the CO2 emissions from a car which remains in the air for much longer time. However, it is this release of energies that is powering the rapid chemical reaction taking place as the paper's molecules begin to break apart and form new compounds.
One BTU equals heat loss value or energy put off by certain kinds of fuel once it has burned. Natural gas and renewable energy like thermal power is measured in BTU. Energy saving levels for air conditioners can be measured in BTU units.A BTU is a standard unit of energy used to measure the number of heat pumps required to lower or raise the temperature of 1 pound (lb) of liquid water by 1 degree Fahrenheit. One BTU will raise the temperature of 1 pound of water exactly by 0.55 degrees F, therefore 12000 Btu/hr will raise 55 lbs (about 8 gallons) of water by that much each hour.
The British thermal unit (BTU), is an energy measurement unit based on the International Steam Table calorie, which was created at the same time. According to energy information administration, it was defined so that the boiling point of water is exactly 100 degrees Celsius or 212 degrees Fahrenheit temperature. "British" refers to this standard being established by the British Standards Institute in 1929. The BTU rating is used globally.
The units on your appliances may indicate kW or KJ per hour. Simply multiply by 3 to convert from kW to BTU per hour. For example, a standard oven uses about 5500 BTU/h.
An air conditioner uses about 3412 BTUs an hour. An evaporative air conditioner uses around about 6,000 watts or 6 kilowatts (6 kW) of power in the form of electricity for each air conditioning unit. This unit shows how much energy an air conditioner uses per hour. When buying a new air conditioner, choosing the one with the right BTU rating is important otherwise it may consume more power. A more powerful air conditioner means higher BTU. This unit is utilised for the calculation of the cooling power of heavy cooling electrical appliances such as air conditioners. The BTU is often used in power plants as they have a larger unit of appliances.The BTU, is a common unit of measure for various energy sources. One BTU is the heat demanded for increasing the set temperature by one degree F of water. A British thermal unit hour, or BTUH, is a unit of measure used in sizing heating and cooling systems. It represents the amount of heat that would be released if 3412 BTUs were burned in an hour.
A BTU is the energy needed for heating up water (single pound) one degree Fahrenheit temperature (at sea level).
KW stands for Kilowatts or wattage, which is a measure of power or heat flows over time. One kilowatt hour (KWH) means you've used one kilowatt's worth of energy. That's why wattage and KW are sometimes used interchangeably when measuring appliances that use electricity, like your dryer, refrigerator or vented air conditioning unit.If you are looking to estimate how many British thermal units (BTUs) are required annually to heat your home all you need is the total square footage of space your house occupies. Divide this figure by 10 and you will have the BTU output required to heat a single room or your whole house. You can calculate in square feet or square inches. Keep in mind this is an estimate. To calculate the heating requirement use: square foot x 10. Example: A 1500 square foot home would require 15,000 BTUs per hour.
