Heat Pump Tonnage Calculator

Formula

The formula to calculate the Tonnage (T) is:

$T = \frac{BTU}{12,000}$

Where:

(T) is the tonnage of the heat pump
(BTU) is the British Thermal Units per hour (BTU/h)

What is Heat Pump Tonnage?

Heat pump tonnage refers to the heat output capacity of a heat pump. It is a measure of how much heat a heat pump can remove from a home in an hour. The term “tonnage” comes from the fact that it used to take 1 ton of ice to cool a room for 24 hours. Therefore, a 1-ton heat pump can remove as much heat as 1 ton of ice would absorb in melting over a 24-hour period. This measurement helps in determining the right size of heat pump needed for a particular space or building.

Example Calculation

Let's assume the following value:

British Thermal Units (BTU) = 36,000 BTU/h

Using the formula:

$T = \frac{36,000}{12,000} = 3 \text{ tons}$

The Tonnage (T) is 3 tons.
