KWH Technik GmbH

Our 29-year-old Buderus gas heating system was replaced in May 2025 by KWH Technik GmbH – as requested – with a Bosch heat pump system, including hot water preparation and storage. The work was completed within 5 working days, to a high professional standard. In January 2026, at our express request, a feature was installed, the function of which seems to have been overlooked in Bosch's standard programming over the years. Now we are absolutely delighted. Thank you, KWH Technik GmbH! P.S.: We sent our request for proposals for the heat pump system to 7 companies at the beginning of January 202

Highly recommended. We had our heating system upgraded. The team was proactive and made helpful suggestions for improvement. Pricing was transparent, and communication was very professional. And when problems arose, they were very solution-oriented. While I hope the heating system lasts for years to come – KWH, we'd gladly use them again!

We are completely satisfied with KWH Technik GmbH. They replaced our 30-year-old gas heating system with a heat pump. Everything went smoothly from the initial planning stages to the final installation. We were able to choose from several manufacturers. Agreements were always honored, and the employees were punctual and worked very cleanly and conscientiously. Mr. Wölwer also had some excellent ideas during the planning phase that helped us with the implementation. Professional and highly recommended.

KWH-Technik provided me with excellent advice regarding the installation of a heat pump. Therefore, I placed an order with them. The work was completed on schedule. I am extremely satisfied with the installation. The post-installation briefing was comprehensive and very easy to understand.

We needed KWH Technik for several plumbing jobs. The expert advice from Mr. Wölwer, as well as the execution and workmanship, completely convinced us. The work site was left clean. We can wholeheartedly recommend this company.
