Furnace BTU Calculator

Calculate BTU for Your Furnace





What is BTU?

BTU (British Thermal Unit) is a unit of heat used to measure the heating capacity of a furnace. This calculator helps you determine the required BTU based on your room's area, ceiling height, and climate zone.

Formula

The formula to calculate the required BTU is:

\[ \text{BTU} = \text{Room Volume (sq ft)} \times \text{Climate Factor} \]

Example Calculation

Consider a room with an area of 200 sq ft, a ceiling height of 8 ft, and located in a moderate climate zone:

Using the formula:

\[ \text{Room Volume} = 200 \times 8 = 1600 \text{ cubic ft} \]

\[ \text{BTU} = 1600 \times 40 = 64000 \text{ BTU} \]

This means the required BTU is 64000 BTU.
