What is a heat pump?

A heat pump is a system that moves heat instead of generating it. It uses a refrigeration cycle to transfer heat from one place to another. In heating mode, it extracts heat from the outside air (even in cold weather) and moves it indoors. In cooling mode, it reverses the process, removing heat from inside and releasing it outside. This allows it to efficiently heat or cool a space using minimal energy.

Heating Mode

In heating mode, the heat pump extracts low-temperature heat from the outside air, even in cold weather, and transfers it indoors. This is done by absorbing the heat through the evaporator, compressing it to increase its temperature, and then releasing the higher-temperature heat into your home through the condenser.

Cooling Mode

In cooling mode, the process is reversed. The heat pump pulls warm air from inside your home, absorbs the heat through the evaporator, and releases it outdoors. This efficiently cools your living space by dissipating the heat outside and circulating cooler air indoors.
