Gas condensing solar centre
CSZ-2R

Eligible for subsidies, the CSZ-2R is the perfect combined solution for solar and gas. Perfectly matched, highly efficient and space saving.

Do you want to use free solar energy for most of the DHW heating in your detached house? Then the WOLF CSZ-2R gas condensing solar centre, combined with WOLF TopSon F3-1 solar collectors, is the efficient and resource saving heating system for you. All the components of your solar centre come from a single source and are perfectly matched. This makes them particularly reliable and efficient.

The CSZ-2R can provide up to 60 % of the energy required for DHW heating from the solar thermal side. This significantly reduces your gas consumption. Furthermore, the CSZ-2R is eligible for subsidies according to the Renewable Energies Heat Act [Germany]. Find out more on our Subsidies page.
Also good to know: despite the large 300 l DHW cylinder, the CSZ-2R requires a footprint of only around 0.5 m2, for example in the roof space or basement. The appliance operates extremely quietly, so you can pursue your hobbies or sporting activities without being disturbed.

Technische Daten

GAS CONDENSING SOLAR CENTRE CSZ-2R

The perfect combined solution comprising gas and solar for DHW heating.

The solar centre heats spacious detached houses and apartment blocks, and consists of the following components: WOLF CGB-2 gas condensing centre, BM-2 programming unit, 300 l solar cylinder, a high efficiency solar pump assembly including WOLF SM-1 solar controller, 25 l solar expansion vessel and the container for the solar fluid. The solar cylinder is sized for three solar collectors. You can control the entire system with utmost convenience via the BM-2 programming unit. In addition, the system can be very easily integrated into a SmartHome system via an extension module.

Solar cylinder with high quality thermal insulation, including floor insulation, prevents quick cooling down and unnecessary operation of the system
Highly efficient: in combination with a solar thermal system, energy efficiency class A+ is achieved for the entire heating system
Versatile siting options within the home: the appliance fits into any corner and features a stylish, compact design
Good access to all components for convenient operation and quick, time saving service
Energy saving thanks to solar boiler stop, i.e. the boiler switches off when sufficient solar heat is available
Equipped with the new SmartHome-enabled WOLF control system, allowing you to operate and monitor the system even while out and about
