The diamond with the initials "THE”, which stand for Theodor Heimeier Erwitte, has developed into a quality seal in the heating industry. Almost every second thermostatic valve which was installed over the past years in Germany, the world’s largest thermostatic valve market, came from Heimeier. The K-head with its typical design and Heimeier logotype has thus become an integral part of homes and offices. A great success story which is based without question on the consistently implemented company values such as tradition and innovation, quality, variety of products and the partnership with trade and the craft trades. These recipes for a successful company policy have enabled Heimeier to become a leading manufacturer on the international markets as well. Fittings from Heimeier are known all over the world. An important building block for this outstanding success was the decision made at the end of the 1960’s to rely consistently on a sensor with incompressible filling for thermostatic valves. This principle pursued by Heimeier turned out to be the best solution not least owing to its outstanding precision control, and today it is still the absolute standard. The further typical features of the Heimeier thermostatic valve such as the double O-ring sealing, the M 30 x 1.5 adaptor, the gunmetal casing with optimised flow or the excellent user friendliness were the reasons for the unparalleled triumphal march of the Heimeier thermostatic valve. Not least owing to these features Heimeier was awarded the best mark "very good” four times in a row by the most important German consumer testing organisation, "Stiftung Warentest” – a unique end result. Tried and tested millions of times The Heimeier thermostatic valve.
