Heat Pumps

Improve Economic Performance

Heat pumps can be installed to improve the economic performance of your building hot water requirements. A heat pump is essentially an air-conditioner operating in reverse. When used for heating, a heat pump, in effect replaces the current geyser’s (hot water tank) electrical element as an alternative source of water heating.

The system employs an evaporator, a compressor, a condenser, refrigerant gas, and an expansion valve as its main components, forming a closed heating circuit. Operational times and desired water temperature can be custom set to suite guest’s hot water requirements and peak demand periods. For large buildings with high volumes of hot water requirements, a large central heat pump system may be more cost-effective.
