In Europe, many houses are heated by ground-source heat pumps (GSHPs). They absorb heat from groundwater, wells or streams and release it, for example, to underfloor heating systems. Unfortunately, this water is corrosive. It quickly corrodes the equipment with which it comes into contact. Spirec evaporators are used in a large number of geothermal heat pumps manufactured in Europe. They are made of 316L stainless steel. they are fully welded and seamless. Therefore, they are resistant to corrosion and freeez-up. Spirec adpats the hydraulic and refrigertaing connections of the exchangers to facilitate their integration.
The system
Spirec customers heat pumps include :
- A heat-insulated Spirec evaporator connected to the ground water pumping unit
- A compressor, expansion valve and regulation
- A Spirec condenser connected to the heating network
