HS Heating Solutions GmbH

We've been working with HS Heating Solutions for two or three years now and are very happy with the collaboration. From the initial inquiry and planning stages to the final execution, we are completely satisfied. We would like to emphasize their accessibility and communication, which has always made our work easier. We can wholeheartedly recommend HS Heating Solutions as a business partner and look forward to future projects.

On the recommendation of a friend who is an energy consultant, I obtained a quote from HS Heating-Solutions in July 2025. It was important to me to hire a local company (Darmstadt/Dieburg area) that installs Lambda heat pumps. This is by no means a given, as it requires specific manufacturer training, which not every heating contractor has completed. With some lead time due to delivery times, the project was scheduled for January and then completed promptly and efficiently. In our detached house, a 21-year-old Viessmann gas boiler was removed and replaced with a Lambda EU10L. Underfloor heating is installed on the ground and first floors, and some radiators are also present in the basement and attic. The heating circuit manifolds were replaced with calibratable manifolds for hydraulic balancing. I was able to contribute my own work, such as excavation, foundation work, and preparing the cable routes, after prior consultation – this was facilitated openly and without complications. Overall, the work was carried out cleanly, reliably, and professionally. The coordination with the partner electrician also went smoothly, including the consideration of individual requests. The clean organization of the construction site was another positive aspect: all walkways were covered with non-slip matting, and a temporary hot water supply and space heaters were provided – not only helpful but essential in January. The quote was transparent and clearly itemized, even though the technicians' hours were grouped together within the individual items and flat rates. Thank you for the excellent work.

Although we ultimately couldn't proceed with the project due to time constraints on our side, working with HS Heating Solutions was a great experience. They were professional, took the time to answer our questions thoroughly, and helped with detailed measurements and calculations We wouldn't hesitate to recommend them to anyone looking to renovate or install a heating system.
