Vaillant uniSTOR RW cylinder for heat pumps

uniSTOR RW is a hot water cylinder with a large surface coil, designed to work with heat pumps. It suits homes that already have, or are about to install, a heat pump and need the right hot water storage.

Capacity: 200–500 L
Energy class: B

Heat pumps produce water at a lower temperature than boilers, so a standard cylinder transfers heat too slowly; the large coil area of the RW series solves that. The 200 litre model measures 1,222 × 596 mm and fits into tight utility spaces.

A B energy class and high corrosion protection keep the cylinder working efficiently for years. We commission the heat pump and the cylinder together and set the hot water priority to match your system.
