The heat pump: an efficient dehumidifier

The heat pump is a highly energy-efficient auxiliary heating system, which allows for air conditioning in the summer and heating in the winter. It can also serve as a dehumidifier, a feature often forgotten by its owners. When should this function be utilized?

The heat pump can operate all winter as an auxiliary heating system, and during heatwaves as an air conditioning system. However, it’s difficult to choose between the two during spring or autumn days, rainy days, or on summer days when the temperature is simply comfortable outside. Indeed, if the “automatic” function is set on your heat pump, it will switch between heating and air conditioning on these temperate days, a scenario that is not very cost-effective. In this case, it’s recommended to activate the “dehumidifier” function on your heat pump.

Controlling humidity levels with your heat pump

For temperate days, air conditioning is not necessary, and your main heating can take care of warming your house if needed. The heat pump, on the other hand, is perfect for controlling the humidity levels in your home, which can rise quickly on rainy days or when your home is not necessarily heated or air-conditioned. An ideal humidity level is between 35% and 45%. This level is difficult to maintain without the help of a heating system or an air conditioner. Thus, the “dehumidifier” function of a heat pump is a very advantageous feature to avoid problems related to humidity, such as condensation on the windows or the potential appearance of mold.
