Thermal Storage


Thermal storage is essential for biomass systems, particularly firewood boilers.  An adequately sized heat storage tank will add efficiency to a system by reducing short cycling and optimizing combustion.  The storage tanks we supply are all equipped with enough ports for boiler supply and return, heating system supply and return and at least two ports for temperature probes.

Please contact us to have us help you determine what size of heat storage you’ll need for your Fröling boiler system.
