Heat pump installation

Translated from German

“I had TK SHK install a heat pump and I am really very satisfied. Everything went very well, from the initial consultation to completion. The work was carried out cleanly, punctually and very carefully. Questions were always addressed and everything was explained clearly. You can tell that they have expertise and experience. The heat pump works perfectly and I would hire TK SHK again at any time. Highly recommended!”

Die Arbeiten wurden sauber, pünktlich und sehr ordentlich ausgeführt. Auf Fragen wurde immer eingegangen und alles verständlich erklärt. Man merkt, dass hier Fachwissen und Erfahrung vorhanden sind. Die Wärmepumpe läuft einwandfrei und ich würde TK SHK jederzeit wieder beauftragen. Klare Empfehlung!“

gas boiler replacement

Translated from German

“I had my old gas boiler replaced with a new combi boiler and I am really happy. An appointment was arranged quickly and installation went smoothly. The old boiler was removed and the new one installed straight away. The heating and hot water work perfectly again, and everything was left clean. The price was also as discussed beforehand. I can definitely recommend them 👍”
