Wärme mit Konzept GmbH

Super!

In late summer, we decided to upgrade our house's heating and energy efficiency (heat pump and photovoltaic system) for the future, and we found a fantastic partner in WMK. From the initial consultation and component selection to the grant application and installation, everything was handled by a single, competent, and professional team, all of whom were very friendly. The work was carried out quickly and efficiently, with a well-coordinated approach. The work was done professionally and cleanly, and everything was running perfectly from the start. A reliable and service-oriented partner, very

The photovoltaic system with storage was handed over to me by your electricians on September 30, 2025, and I accepted it as fully functional. The app I downloaded to my iPhone for viewing data on the photovoltaic system, storage, and grid operation (connection to/from the grid) works well and I'm very happy with it. The roofers who installed the photovoltaic system worked very quickly and cleanly. The electricians also worked very quickly and cleanly. The delivery of all components and the subsequent installation were very well coordinated without any downtime. WMK fully met all my expectat

We are very satisfied with WMK's work! A 12kW heat pump was installed in our old building in January. This replaced our 25-year-old gas boiler. The installation involved some extra work, as the heat pump had to be lifted over the roof onto the roof terrace using a 24-meter crane, and the indoor unit had to be installed under the roof. The old radiators and valves did not need to be replaced. All work was carried out very carefully, and the system has been running flawlessly for a week now. Many thanks to the entire team for the meticulous work and the comprehensive advice! Best regards, Thom
