![]() If you are struggling to find an accurate estimate for the power of heating required you can reach out to us using our Contact Form or by calling us on 03. Knowing the heat loss, we can estimate the power of a heater. For more information, dont hesitate to get in touch with Great Rads today. With this information, we can compute the heat loss (in watts divided by the temperature difference). Calculate your rooms BTU requirement using our handy radiator BTU calculator. The ambient temperature should be the minimum temperature occurring in your region. The internal temperature depends on your comfort. The last bit of the information needed is the difference of temperatures between inside (internal temperature) and outside (ambient temperature). In the advanced mode, you can also include the number of windows and doors. You should also specify how many external walls there are. If you are unsure which insulation type to choose, go for the worse insulation. To find the power of the heater you need to give the dimensions of your room, specify on which floor it is and what type of insulation the walls have. You can use this calculator to estimate the power of a heater needed to keep your room at a comfortable temperature. ![]() There are tables with heat contents for fuels and electricity in the appendices of the Monthly Energy Review.The BTU (British Thermal Unit) Calculator allows you to calculate an accurate estimate size for the wattage of heating required for any given space based on a number of parameters such as room size (including ceiling height), internal temperature, ambient temperature and the level of insulation. The Btu conversion factors above are approximations. Wood heat content varies significantly with moisture content. A cord of wood is a volume unit and does not take wood density or moisture content into account. It is based upon the amount of energy to heat one pound of water. Energy Information Administration (EIA) Definition of the British thermal unit (Btu) and how Btu is used to compare different energy sources. Knowing your required BTU to heat your space is an important part. One therm is the energy content of approximately 100 cubic feet (2.83 cubic metres) of natural gas at standard temperature and pressure. The British Thermal Unit (BTU) is a standard measurement of heat energy. Coal-545.67 million short tons-10.55 quadrillion Btuġ Btu factors are for end-use consumption in 2021 from Monthly Energy Review, May 2022, excluding wood preliminary data for 2021.Ģ Natural gas consumed by end-use sectors (excluding electric power sector).ģ Finished motor gasoline sold at retail in the United States, including fuel ethanol content.Ĥ Distillate fuel with 15 parts per million (ppm) suflur or less sulfur content.ĥ Distillate fuel with 15 ppm to 500 ppm sulfur content.Ħ This conversion is an estimate. BTU (British Thermal Unit) is the most common unit of heat measurement in the United Sates. The therm (symbol, thm) is a non- SI unit of heat energy equal to 100,000 British thermal units (BTU), 1 and approximately 105 megajoules, 29 kilowatt-hours, 25 200 kilocalories and 25.2 thermies.Natural gas-30.29 trillion cubic feet-31.34 quadrillion Btu.Petroleum-7.22 billion barrels-35.07 quadrillion Btu.EIA converts those amounts into Btu equivalents to compare the sources on an equal basis.įor example, the physical volumes of fossil fuels consumed in the United States in 2021 and Btu equivalents were: BTU factor is simply BTU divided by 1000. Energy Information Administration (EIA) uses Btu as a unit of energy content.ĮIA collects data on the physical amounts (volume or weight) of energy sources produced, imported, exported, and consumed. BTU content can be obtained from the gas composition analysis as shown in Chapter 1. Fuels can be converted from physical units of measure (such as weight or volume) to a common unit of measurement of the energy or heat content of each fuel. How to Calculate Tons of Cooling for a Cooling Tower. Temperature is the level rather than amount of heat. The British Thermal Unit measures the amount of heat, or thermal energy. Why use British thermal units?Įnergy or heat content can be used to compare energy sources or fuels on an equal basis. BTU, or the British Thermal Unit, is the amount of heat required to raise one pound of water one degree Fahrenheit. In 2021, the United States used about 97.33 quadrillion Btu of energy. ![]() One British thermal unit (Btu) is approximately equal to the energy released by burning a match.Ī single Btu is very small in terms of the amount of energy a single household or an entire country uses. 1 Kilowatts 3412.14 British thermal units per hour: 10 Kilowatts 34121.42 British thermal units per hour: 2500 Kilowatts 8530354.08 British thermal units per hour: 2 Kilowatts 6824.28 British thermal units per hour: 20 Kilowatts 68242.83 British thermal units per hour: 5000 Kilowatts 17060708.
