The Boiler Buddy is designed to be used in heating systems with low-mass boilers, geothermal, chilled water applications, or low-mass radiation. Boilers operating at low loads will short cycle which leads to sooting, premature component failure (nuisance lockouts) and inefficiency. The Boiler Buddy tank is a factory insulated and jacketed storage tank, adding mass to the system and providing the necessary buffer to prevent short cycling.
