What sizes of Air Source Heat Pumps are needed for a Heating Area of 800 Square Meters

To determine how big an air source heat pump is needed for a heating area of 800 square meters, the following factors usually need to be considered:

1. The power of the heat pump

Generally speaking, the power of an air source heat pump is measured in kilowatts (kW). Usually, a heat pump power of 1kW can heat an area of 10-15 square meters. Therefore, a heating area of 800 square meters requires about 43-80kW of heat pump power, and 1 horsepower of an air source heat pump is approximately equal to 0.735 kilowatts (kW), which means that a 60-horsepower air source heat pump or two 30-horsepower units are used together to heat an area of 800 square meters.

2. The thermal insulation performance of the house

If the thermal insulation performance of the house is good, the required heat pump power will be relatively low; otherwise, a higher power will be required.

3. Local climatic conditions

In cold areas, the power demand of the heat pump will be higher.

4. Usage requirements

Do you need heating all day long, or only during specific time periods?

It is recommended to consult a professional HVAC engineer or supplier when choosing a specific model and power of an air source heat pump to ensure that the selected equipment can meet actual needs.
