A split heating unit is a type of heating system that is comprised of two separate components. The first component is an outdoor unit, which houses the condenser and compressor. This component is responsible for releasing heat from the refrigerant and then transferring it to the indoor unit. The second component is an indoor unit, which contains the evaporator and fan. This component is responsible for circulating the heated air throughout the home. Split heating units are a great choice for homes that have limited space, as the outdoor unit can be installed away from the home. Additionally, these units are energy efficient and provide a comfortable level of heating for the home. Split heating units are becoming increasingly popular as they provide a cost-effective and efficient way to heat a home.
