Our Products

With the hansetherm brand, we offer air-to-water heat pumps that live up to their Hanseatic origins. The installed, high-quality components from Panasonic and Grundfos, among others, are the basis of a durable and consistently efficient product. In addition to long warranty periods adapted to customer needs, you can reach our customer service around the clock, which will take care of your concerns immediately. Furthermore, at very competitive prices, you will receive a delivery date upon conclusion of the contract, which we guarantee – should this not be met, you will receive the product free of charge.

Reliability through proven processes

We place the highest demands on our production and trading partners. We also have these demands on ourselves: That is why we have had our strict quality management and our environmentally conscious actions audited and certified.
