Horizontal earth collectors
Earth collectors are used for detached and semi-detached houses in rural areas. The heat is taken away using horizontally laid pipelines in the area of the plot that is not built over.
HakaGerodur AG offers earth collector pipes made of PE 100-RC and KITs, which include the complete brine circuit. The dimensioning complies with VDI4640. We will be glad to send you reference tables on the current available heat pumps.
