How to choose the right power of your heat pump?

In order to offer you better energy efficiency, you must choose a model that suits the size of your space (the right BTU / room size ratio).

Essentially if you do not want to be too cold or too hot, it is essential to choose the best solution.

Indeed in the summer when you use it to cool the space the heat pump will also dehumidify the air, which will bring you a very comfortable dry cold. If you opt for a machine that is too powerful, the humidity will not have time to be evacuated and you will have cold and damp air, which can be very unpleasant.

Just as in winter when you want to heat the space, the heat pumps push very hot air to be able to raise the temperature quickly in the room, if the machine is too powerful it can be very unpleasant.

How to calculate the power of my heat pump?

For this you must measure the size Length x Width (example: 10 ft x 30 ft = 300 ft²) then as you can imagine the heat or the cold is directly impacted by the number of uninsulated walls, you must therefore add the number of windows or doors to the outside (depending on the quality of insulation add 50-150 ft² per window or per door)

Example for a 300 ft² dining room with 4 windows and 1 door to the outside you will get 300+(5x100) = 800ft² which requires a 12,000BTU/h model.

Depending on the result you can use the table below to choose the number of BTU/h you need



9000 BTU/hr

100-400 square feet

12000 BTU/hr

400-900 square feet

18000 BTU/hr
900-1200 square feet

24000 BTU/hr

1200-1600 square feet
