Solar domestic hot water cylinders

For heat pumps

WWSP 432 SOL

Solar domestic hot water cylinder made of steel (special inside enamelling) with protection anode, two integrated bare-tube heat

exchangers for solar and heating. Thanks to the temperature stratification, even small solar gains are sufficient to feed energy into the

lower cold water section of the cylinder. The upper part of the cylinder is kept at the comfort temperature. Thermometer, polyuretha-

ne insulation for low standby losses, colour white, flange TK 150/DN 110. An NTC 10 and an NTC 2 sensor are included in the scope of

supply.

Solar station for domestic hot water

Solar back-up for domestic hot water preparation

SST 25

DWUS 25 SOL

Heat exchanger solar station consisting of a solar separation system and pump assembly with insulation jackets for integrating solar

installations up to 10 m² into the domestic hot water heating system. The solar station enables efficient hot water heating via the heat

pump and the solar installation. Modules with a primary and secondary circuit consisting of: 2 circulating pumps (WILO- STAR-ST 25/6

and STAR-RS 24/4); 4 ball valves 1“ with thermometer, return inhibitor, safety module with safety valve and 0–10 bar pressure gauge,

connection options for expansion vessel (solar controller not included in scope of supply).

Solar collectors and accessories

Solar reversing valve

Three-way reversing valve for switching from solar energy systems to domestic hot water preparation or supplementary heating. Motor

operated for short switching times (set time open 12 s, set time closed 6 s); for a maximum volume flow of 2 m²/h; maximum differential

pressure 0.6 bar; temperature operating range for solar energy systems from -20–160 °C; maximum ambient temperature 50 °C.
