Our Heat storage tanks provide mains pressure hot water for baths and showers by means of a corrugated stainless-steel heat transfer coil. They also act as a heating buffer to allow the integration of multiple heat sources into a single heating and hot water system. These tanks safely store heat as it is generated, so that it can be used for space heating and/or mains pressure hot water production, later on. In addition to storing heat from intermittent heat sources, these tanks simplify the connection of multiple heat sources to your heating system, making it easier to install, configure and operate. Hydrofire offers a variety of heat exchangers and assembly kits.
