A ductless heat pump works by taking warm air from one location and moving it to another. It consists of both an outdoor compressor unit and indoor air handling units. These systems are either single-zone systems or multi-zone systems based on the number of units. In a ductless heat pump system, heat is transferred through a cycle of evaporation and condensation, as a refrigerant substance cycles through the system via a compressor pump. Every ductless heat pump contains two heat exchanger coils, one which condenses the refrigerant and another which evaporates it. The refrigerant absorbs heat from the surrounding area during the evaporation process.
Benefits of a ductless
Ductless heat pump systems offer numerous benefits including retrofitting into buildings that do not currently contain duct work. These are ideal for homes with radiant (hydronic) heat, electric baseboards or space heaters as their main heating method. As a result, ductless heat pumps offer ideal solutions for areas that require supplemental heating, where installing additional ductwork might not be convenient, or if the space is small.
Each indoor air handling unit contains its own thermostat because it is self-contained within the system. This makes temperature control throughout the home fully customizable, helping to save on energy costs while still keeping you comfortable. You can even spot heat certain zones or rooms as needed, independent of the central system. Because the system is fully reversible, a ductless heat pump can also help to cool your home during summer months.
