The IBT buffer tank is designed to reduce burner short cycling with low mass boilers when the heating system zone load requirements are less than the minimum  thermal output of the boiler.  

Reduced burner cycles improves efficiency and comfort as well as decreasing wear on boiler components.

The IBT also provides a thermal buffer as well as hydraulic separation, to decouple the heating distribution system water flow from the boiler water flow. The result is consistent water flow rates on both sides of the heating system.

Quality Construction

• 444 grade Stainless Steel vessel
• 316L grade stainless steel connection fittings

                 Two 1.5” NPT ports for the boiler circuit

                 Two 1.5” NPT ports for the system circuit

• 3/8″ ID thermal well for temperature control
• 2″ thick High Density foam insulation
• Galvanized and Powder Coated steel jacket

Durability

• All welds are made by a high quality, automated TIG welding process, eliminating the possibility of crevice corrosion. The entire tank is then pickled and passivated both inside and outside improving overall corrosion resistance. There is no substitute for stainless steel when it comes to water heating and storage.
