We design and manufacture industry-leading hydronic products and solutions that give you control at every turn and help create energy-saving, cost-efficient HVAC installations.
Ensuring you have control at every turn is what we’re all about. We’ve developed a range of applications and software downloads to help you design, install and optimise every type of HVAC solution.
We are the Hydronic Engineering experts. We invented the concept, created products to back up the theory and love sharing best practice at our Hydronic College and through regular training seminars.
Download library We’ve created an extensive library of product-related technical documentation and a wide range of other useful information to help you get the most out of our globally-renowned products and solutions.

KEYMARK certified and tested according to EN 215. See also leaflet "Thermostatic Heads - General".
Surface closed on all sides. Particularly suitable for hygienically demanding areas in health care or food / industrial sector.
Designed to be mounted on all HEIMEIER thermostatic valve bodies and radiators with integrated valves which have an M30x1.5 thermostatic insert.
Thermostatic head Halo
The thermostatic head Halo is used to control the temperature of individual rooms using, for example, heaters, convectors, and radiators. The Halo head combines high precision control with slim, cylindrical design.
