PFW-R Multifunction Tank, incl. Insulation
Complete solution for heating, domestic hot water, and solar energy for single-family, two-family, or multi-family homes.
They ensure a constant supply of hot water without temperature fluctuations for drawing fresh water using a fresh water station that operates on the flow-through principle.
The fresh water station and the two heating circuit stations can be mounted directly on the storage tank. The internal piping ensures ideal stratification within the storage tank. Our PWF-R multifunction tank was developed in collaboration with Tuxhorn. You can find the corresponding components in Tuxhorn’s product portfolio.
Buffer tank for all hot water central heating systems. Suitable for: solid fuel and oil-fired boilers, heat pumps, solar systems, and gas or electric instantaneous water heaters. Manufactured from high-quality S235JR steel in accordance with EN 10025 and EC Directive 97/23/EC; exterior with anti-corrosion coating, interior left unfinished. Includes a sensor terminal strip for variable positioning of the sensors.
