Discover the BuffMax’s multiple applications and advantages by reading our product documentation below.

Buffer tank The tank that makes all the difference.

The BuffMax from Thermo 2000 is a 3-in-1 solution that acts as a buffer tank, storage tank and hydraulic separator. It is recommended to optimize the performance of several different types of heating systems: low-mass boilers, biomass systems, geothermal and heat pump applications, multi-zone systems, and solar energy systems. The BuffMax is synonymous with versatility. Thanks to even better polyurethane insulation, BuffMax standard tanks from 20 to 120 gallons (non ASME) are now compatible with heating AND chilled water applications. You get the best of both worlds, a versatile solution that meets all your needs without compromise and at no extra cost. The BuffMax’s tank comes with a 5-year warranty, and its mechanical parts come with a 2-year warranty.
