Assar Thomasson started a plumbing company in Marbäck in 1951. Like most plumbers, he considered different ways of improving and developing the products within the industry. The result was the company BT-ventiler, which manufactured the so-called vacuum clip valve that prevented drips from the injectors in oil burners. Another product was Termoshunt, which used bimetal regulation of the supply temperature, and was controlled by a liquid-filled bulb placed outdoors. In 1981 Termoventiler AB was established with the aim of developing and selling valves and automatic controls for accumulating heating systems under the trademarks Laddomat® and Thermomatic®.

After running the company successfully, Assar Thomasson retired and handed over to his son Anders who further developed the company and the products. In 1998 the operations moved to purpose-built premises in Marbäck in the beautiful Ulricehamn Municipality, where all the company's products are manufactured. In 2006, Anders Thomasson sold the company to the Pomona Group – a strong and long-term industrial owner that is owned by the Rapp family. The company is very well equipped to meet the future, both in terms of financial position and product development.
