BTU (British Thermal Unit) is a unit of heat energy used to measure the heating or cooling capacity of an appliance. This calculator helps you determine the required BTU for a radiator based on your room's dimensions, insulation quality, and number of windows.
The formula to calculate the required BTU is:
\[ \text{BTU} = \text{Room Volume (cubic feet)} \times \text{Insulation Factor} \times \text{Window Factor} \]
Consider a room with the following dimensions and factors:
Using the formula:
\[ \text{Room Volume} = 20 \times 15 \times 8 = 2400 \text{ cubic feet} \]
\[ \text{Insulation Factor} = 1.25 \quad (\text{for average insulation}) \]
\[ \text{Window Factor} = 1.1 \quad (\text{for 2 windows}) \]
\[ \text{BTU} = 2400 \times 1.25 \times 1.1 = 3300 \text{ BTU} \]
This means the required BTU for the radiator is 3300 BTU.
