As manufacturer for heat pumps it is our obligation to check all
products. Our quality management based on typical German roots. We check every supplier and the whole production all the time.

Every heat pump is checked for noise level, air volume and functions.
Before production, during the production and after production.

All tests we do in our own lab, in independent labs and in labs of our suppliers. In this case we can improve GDH-heat pumps – if fan, evaporator, noise level…

Our technicans collect all test results to improve the
heat pump. In cooperation with our purchase department we compare all components by quality, price, availibility and nesccary for the excatly requierements of difference countries.

Renewable energy must be affordable.
