Boiler Buddy Full Size Logo

Your Boiler’s Best Friend!

Boiler Buddy tanks are 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 that adds mass to the system and provides the necessary buffer to prevent short cycling of the heat source. It also serves as a hydraulic decoupler, separating the boiler loop from the system loop and provides an excellent location to eliminate unwanted air.

Made in the USA!
