What our customers say

“We have been installing products from Kermi GmbH for many years now. With Kermi energy saving radiators, such as the therm-x2, the owners and tenants of our properties can save up to 11 percent on energy.

Of course, this is a vital point for us to put across when we’re letting or selling the housing units.”

Martin Dornrieden
Managing Director of Dornrieden Generalbau GmbH in Mönchengladbach

“We weren’t always able to work with standard construction products as far as the depths of ventilation units or ducts were concerned, for example. 

Kermi provided us with outstanding support in this area. I really don’t think the apartments would have been ready to move into so quickly without Kermi’s input.”

Robert Decker
Managing Director and proprietor of Timber Homes
