Actuators for Underfloor Heating
Every year millions of Möhlenhoff thermal actuators are produced and sold world-wide to be used in underfloor heating.
Actuators for Underfloor Heating
Many homes with underfloor heating are equipped with Möhlenhoff thermal actuators. Designed to last for more than 10 years with the same performance as from day one, with their excellent quality our actuators modestly provide in silence optimized comfort control for our customers, day in and day out.
But also for project owners and installers our thermal actuators are an excellent choice. With their unique valve adapter system they fit on practically any valve or manifold, are easy to install and the first open function enables pipe flushing and building heat up without having to use any control device.
A5 – on/off with 4 or 5 mm stroke
The A5 with its modern design incorporates all technology advancements developed over the years and more: the 1-Watt Power Consumption Technology. The proof of our philosophy: future through ideas.
