Ryser Heizungen GmbH — Dorfstrasse 15, 8902 Urdorf, Switzerland

Mr. Ryser helped me with a ton of questions, a complete water boiler replacement and modernization of the manifolds! Super guy, super business and great work.

We had a new heat pump heating system and heat pump boiler installed. The heat pump is very quiet! Great! All deadlines were met. Excellent work and advice. The quote matched the final invoice. If the heat pump lives up to its promises (we'll only know that in the next 10 years), we will be very satisfied. We were very pleased with Mr. Ryser, his work, and his organization with the authorities, the Elco heat pump team, applications for subsidies, etc. A superb heating installation company and excellent work from Ryser. I will wholeheartedly recommend this company!

Thank you so much for the quick and perfect boiler installation! Thomas explained everything clearly and provided excellent advice. The work was then carried out cleanly and with the utmost professionalism. I would also like to express my sincere gratitude for the loaner unit – it was a great help! Best regards and thanks again for the excellent service!

In October/November 2022, we replaced our old oil heating system with a geothermal heat pump. RyserHeizungen's consultation, planning, and execution of the work were competent and professional. The installation was completed quickly and flawlessly.

I urgently needed a special tool to loosen the faucet. I was able to simply borrow this tool, as Mr. Ryser couldn't come immediately. What a straightforward way to do things – that's what I call customer-friendly!

Fast, uncomplicated, friendly, and very efficient! We will definitely use this tradesman again in the future. Thank you!
