Description

The HRPU is a potable water tank that sits upright on top of a buffer tank. Both are stacked one on top of the other, saving space in the utility room.

The potable water tank is internally enameled in accordance with DIN 4753. Its smooth-tube heat exchanger, made of 1 ¼-inch tubing, is simply coiled along the entire height of the tank. This makes it suitable for condensing boilers and heat pumps.

The buffer tank is made of high-quality S235JR steel in accordance with EN 10025. Both are directly foam-insulated with 60 mm of rigid PU foam, available in silver or white.

  • buffer tank: High-quality S235JR steel in accordance with EN 10025
