Heat from groundwater. The Weishaupt water-to-water heat pumps.

A Weishaupt water-to-water heat pump can produce up to 5.5 kW of heat from 1 kW of electricity. That makes it one of the best energy utilisers on the market.

All of the accessories are perfectly matched to one another, from the pumps rated Class A for energy efficiency to the room thermostats. Weishaupt also takes care of the well drilling and the connection to the heat pump system.

The heat pump also looks after the DHW in the building. One particularly elegant solution is the Weishaupt combi-cylinder (WKS), which unifies all the connection components between the heat pump and the heating system within a compact housing.

Weishaupt water-to-water heat pumps are available with rated outputs from 9 to 100 kW. High-temperature versions with flow temperatures up to 70 °C are available for the replacement of exisiting boilers or the modernisation of older buildings without flat-panel radiators.

Weishaupt heat pumps are among the quietest on the market. This is ensured by multiple vibration dampers, the completely soundproofed inner housing and the high-performance compressor without mechanically operated valves.

Weishaupt's water-to-water heat pumps can be used not only for heating but also for the cooling of buildings. In summer, the constantly low temperature of the groundwater is used to send "cool" water through the system. This so-called "passive cooling" turns the heating circuit into a cooling circuit.

High-quality materials,robust construction, and proven technology ensure that your system will operate reliably for many years. The robustness of Weishaupt water-to-water heat pumps means that almost all qualities of water can be used. A prior groundwater analysis is required for heating outputs of 27 kW and higher.

The system can be easily adjusted in a few steps using the integrated controller with its clear-text Display .

Weishaupt heat pumps are highly efficient and therefore mostly fully eligible for support. You can see what subsidies are available in your case in the Weishaupt subsidy database .
