The US made, ASME rated pressurized tanks are made of carbon steel and delivered with a coating of primer. The vertical orientation of the tanks makes it easy to pass through most exterior doorways and stand vertical. This arrangement saves valuable floor space while allowing for desirable temperature stratification. Insulation is added after the tanks are placed for ease of movement and installation. Tarm Biomass has a wealth of expertise in the application of thermal storage. We provide conceptual installation diagrams for a multitude of installations. We stock most valves and controls for perfect integration of thermal storage with your wood or wood pellet boiler.
