Calculating the BTU for your room. In more moderate climates multiply by 20 - 30.
1 BTU 1055 joules 252 calories 0293 watt-hour or the energy released by burning one match.
How to calculate btu per hour. 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. 1 BTU 1055 joules 252 calories 0293 watt-hour or the energy released by burning one match.
1 watt is approximately 3412 BTU per hour. BTU is often used as a point of reference for comparing different fuels. Even though theyre physical commodities and quantified accordingly such as by volume or barrels they can be converted to BTUs depending.
In warmer climates multiply this number by 10 - 15. In more moderate climates multiply by 20 - 30. And in cold climates multiply the square foot number by 30 - 40.
For example if youre trying to heat 1000 square feet in a cold climate 30000 - 40000 BTUs will add significant warm air to your home. A British Thermal Unit or BTU is a unit of measurement of energy. 1 BTU is the energy needed to heat 1 pound of water by 1 Fahrenheit.
We often refer to the British Thermal Unit as a BTU but the rating is actually the BTUs per hour or BTUh. 1 BTU is the equivalent of 1055 joules or 293 watts. If the room or house you are cooling is heavily shaded you may need 10 percent fewer BTUs to cool it.
If the house or room is very sunny however add 10 percent more BTUs. Room Occupancy The more people that use the area you are cooling the higher the BTUs need to be to compete with body heat. BTUhr Compressor Horsepower x 3000.

One BTU per hour is equal to one british thermal unit or the energy needed to heat one pound of water 1 F for one hour. The btu per hour is a US customary unit of power. Btu per hour can be abbreviated as Btuh.
For example 1 btu per hour can be written as 1 Btuh. A BTU calculation is performed by placing temperature elements in both the inlet and outlet piping of the heat exchanger. Using the difference of these two temperatures and multiplying by the flow rate a BTU calculation is obtained.
This can be used to identify possible fouling or scaling lowering efficiency of the heat exchanger. BTUH BTUs per hour Using our rounded safe number of 1000 BTU per cubic foot on natural gas the required flow rate for this new unit heater would be 1000 CFH 100000 1000 Heating Air with Natural Gas Many air heating applications use steam or hot water coils to heat the air. The power P in BTUs per hour BTUhr is equal to 3412141633 times the power P in watts W.
PBTUhr 3412141633 PW. For a rectangular room multiply the length and width measured in feet. For a triangular room multiply the length and width then divide by 2.
For a circular room measure the radius r which is the distance from the center to the edge. Plug the radius into the following equation. Calculate the LPG Propane Consumption per Hour by Burner Size - Propane Gas Consumption A gallon of propane contains 91502 BTU of heat energy whilst the BTU rating for appliances is in BTU per hour based on burner size.
Dividing 91502 by the BTU per hour rating gives you the number of hours that one gallon of propane will last. Divide the BTUs per hour by the fuel energy content. Our burner with the 40000 BTU per hour output divided by 1075 equals 3721 cubic feet of gas per hour.
This is consumption at 100-percent efficiency Step 4. To get the kW from BTUhr just do the following steps. Obtain the BTUhr of the equipment This can be found on the nameplate or in the catalog.
Divide the BTUhr by approximately 341214 the result will be the equivalent kW. You have a 10000 BTU portable air conditioner what will be its capacity in kW. The result is obtained by dividing 10000BTU by 341214 the result is.
Formula for converting BTUhr to kW 1 BTUhr 0000293071077 kW. This means that one BTU per hour is equivalent to 0000293071077 Kilowatts. Therefore the power conversion of BTU to kW is given by.
The SI derived unit for power is the watt. 1 Btu per hour is equal to 029307107 watt. Note that rounding errors may occur so always check the results.
Use this page to learn how to convert between Btushour and watts. Calculating the BTU for your room. For precise readings youll probably need to hire a qualified heating engineer to calculate the BTU output for you.
However for an estimated reading there are plenty of tools online that can provide a guide. However calculating BTU is not an impossible task and you can even do it all by yourself. Those two numbers multiplied by 133 reveals youll need a little more than 42500 BTUs per hour to keep your workspace at 70 degrees.
Because propane is a clean and efficient fuel that contains more than twice the energy of natural gas its a natural choice for heating systems in any climate.
