Already the ancient Greeks and Romans called this system "hypocaust", in which air heated in a furnace, supplied with stone or fired clay channels, heated the floors and walls. The heat that was gradually accumulated for a long time satisfied the temperature comfort in palaces, bathhouses and houses. Nowadays, using the same principle of accumulation, i.e. collecting and then gradually giving off heat, thanks to the development of fireclay production technology , a much more perfect use of thermal energy has been achieved . Our storage stoves allow you to combine the attractiveness of a traditional fireplace with the recovery of much more heat to the room. We offer ready-made storage furnaces adapted to a specific heating surface. privacy policy District Court for the capital city of Warsaw in Warsaw, Commercial Division of the National Court Register, KRS No. 0000419887, NIP No. 524-249-40-89.
