Why choose the right power for your heat pump?
To offer you better energy efficiency, you must choose a model that suits the size of your space (the right BTU/dimension ratio).
Essentially, if you don't want to be too cold or too hot, it is crucial to choose the best solution.
In summer, when you use it to cool the space, the heat pump will also dehumidify the air, providing you with very comfortable dry cold air. 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 humid air, which can be very unpleasant.
Similarly, in winter, when you want to heat the space, heat pumps push very hot air to quickly raise the temperature in the room. If the machine is too powerful, it can be very unpleasant.
How to calculate the power of my heat pump?
To do this, you need to measure the size Length x Width (example: 10 ft x 30 ft = 300 ft²), then as you might guess, heat or cold is directly impacted by the number of uninsulated walls. Therefore, add the number of windows or doors to the outside (depending on the quality of insulation, add 50-150 ft² per window or door).
Example: for a dining room of 300 ft² with 4 windows and 1 door to the outside, you will get 300+(5x100) = 800 ft², which requires a 12,000 BTU/h model.
Based on the result, you can use the table below to choose the number of BTU/h you need:
Power Space:
12000 BTU/h 400-900 ft²
18000 BTU/h 900-1200 ft²
24000 BTU/h 1200-1600 ft²
