Vaillant Grundwasser-Wärmepumpe

Vaillant offers brine to water heat pumps that, with the right heat exchanger, can be used for open groundwater systems. The Swiss subsidiary in Dietikon coordinates consultation and installation through a network of trained specialist partners.

The Swiss website hosts a guide on water to water heat pumps that covers costs, permit requirements, and typical operating conditions. Anyone unsure whether their property suits an open groundwater system will find initial pointers there on ground surveys and cantonal water rights permits.
