ecotherm Energie u. Umwelttechnik Dortmund GmbH

We had a heat pump retrofitted into our detached house. The entire system was personally planned by Mr. Ucan. Every step was explained clearly and in detail, so we always knew what was being done and why. What was particularly positive was that, despite the relatively small size of the project, he dedicated a significant amount of time to consultation and implementation. The work was carried out cleanly, reliably, and professionally. Overall, a very professional and pleasant experience – highly recommended.

From initial contact to completion, the entire process absolutely deserves 5 stars. We were looking for a local, reputable specialist company. Ecotherm was quickly recommended to us. They have competent, expert staff who work professionally and cleanly. We always felt comfortable with the entire team, and every question was answered. If you're looking for a new heat pump or a new bathroom, this is the place to go. Highly recommended 👍🏻

We are very satisfied. The work was carried out cleanly, quickly, and professionally. Highly recommended.

Ecotherm handled our heat pump and plumbing installation as part of our new construction project. We are completely satisfied: they were easy to reach, the staff were very friendly, and even problems were resolved effectively over the phone.

We first installed a heating system with Ecotherm in 2013 and again in 2024 for a different construction project. Both times we were extremely satisfied! The consultation, implementation, and quality of work were excellent. The team's reliability and professionalism are simply outstanding. We can wholeheartedly recommend Ecotherm. Thank you for the great collaboration!
