Heating buffer storage without internal surface protection with vapor-tight hard polyurethane foam insulation. The wall-mounted version has a wall bracket, and a large electric heating element can also be installed in the system.

It can be used to increase the volume of the heating system, to facilitate the defrosting of the outdoor unit of the heat pumps, but it also has a hydraulic switch function.

When installing, we recommend the use of ERGAS inhibitor, which not only contains corrosion protection materials, but also contains biocide and gas-binding additives.
