A sewage source heat pump system uses sewage as the cold and heat source for energy extraction and storage. With the aid of a compressor system and a small input of electric power, it extracts low-grade heat energy from the sewage to supply heating for users in winter. In summer, heat is extracted from indoor spaces and released into the sewage to lower the indoor temperature and achieve cooling.

Halidom has developed an integrated three-in-one water-source and ground-source heat pump unit for villa households. It delivers cooling, heating, total heat recovery and waste heat recovery functions. In heating mode, it supplies water for underfloor heating and provides domestic hot water all year round. The product is energy-efficient, versatile and simple to control.
