Ceramic enamel internally coated wall buffer tanks developed for heat pumps, the tanks do not include an internal heat exchanger. The ceramic enamel coating protects the heat pump heating system from the possible formation of rust sludge.

The tanks can be placed universally on the wall in both vertical and horizontal positions, as the tank also contains special internal pipe elements. The storage also has adjustable legs. The vapor-tight, closed-cell rigid foam insulation ensures trouble-free operation of the system even at +6°C. The corrosion protection of the tank is also ensured by the protective anode in the tank. The tank can be deaerated with a ball valve when placed vertically.

The buffer tank includes an extra 1 1/2” connection for the electric heating element. The maximum permissible operating pressure of the tank is 6 bar.
