About Thermostone
Thermostone GmbH, based in Merkendorf (Bahnhof Triesdorf Ost), is a manufacturer of infrared heating systems with more than 25 years of experience. The core product is the infrared natural stone heater: each heating element is manufactured as a one-off piece from natural stone selected worldwide in a workshop setting, combining radiant heat with the thermal storage capacity of the stone. The portfolio also includes metal infrared heaters (IP/IHP series, also with glass), high-temperature radiant heaters for halls (EIR series) and dark radiators of the EcoS series for industrial halls, department stores and public buildings. The range is complemented by accessories such as towel rails, stand feet, reflector panels and cable suspensions as well as control technology from analogue to radio to smart home. Sales are handled via specialised retail and wholesale partners; showrooms are available in Merkendorf. Areas of application include residential spaces, commercial use, production and storage halls, churches and listed buildings, sports halls and agriculture.
