About us

KVM-Conheat was founded in 1979 by Kurt Vagner Madsen, whose initials are the source of company name. At the beginning, the small production facilities where located in Vissenbjerg, Fyn, and specialised in district heating units for the Danish market. Through a series of acquisitions and fusions in the 90's and 00's, KVM-Conheat experienced considerable growth. And after fusioning with Genvex A/S in 2014, we moved into larger and more modern production facilities in Haderslev - where we are still located to this day.

Today, KVM-Conheat has 70 employees and is represented all over Europe. With more than 40 years of experience within district heating, we have come far since our humble beginnings. But our values have never changed. We are still driven by a dedication to quality, attention to detail and great craftmanship. And we strive to deliver the best possible solution for our customers – tailored to their specific requirements and wishes.
