Design
Collector frames X
Double-walled, powder-coated aluminium profile in anthracite with integrated glass holder. Welded at the mitre joints, making it particularly torsion-resistant.
Hail-proof collector glass X
The hardened, low-reflection and structured solar glass with a thickness of 3.2 mm is impressive and has particularly good radiation permeability.
Highly selective coating for absorber X
Full-surface absorber made of copper with highly selective coating is an impressive factor with high absorption (95%) and low emission (4%).
Rubber seal X
The 3-lip EPDM seal prevents moisture and dirt penetrating into the collector.
Insulation X
Insulated with rock wool which does not emit vapours. Rear wall: 50 mm thick, side: 20 mm thick.

Benefits
+ Save up to 70 per cent of the costs for hot water heating
+ Save roughly 50 per cent of the total costs for hot water and space heating
+ For on-roof or in-roof installation and also free-standing installations
SolarWIN
Hot water provision
With a solar water heating system, up to 100% of the required energy can be obtained free of charge in summer. Throughout the entire year, up to 70% of the hot water can be heated by solar energy, helping to save costs.
Integrating solar heat for hot water provision is very simple. All you need is an AquaWIN solar indirect coil heating tank. This solar tank is used to integrate the heat into the heating system via the collectors. This is regardless of which boiler is used for heating, whether with biomass or fossil fuels.
SolarWIN
Supplementing the heating system
Depending on the size and design of the solar heating system, the free solar energy can be used either only for hot water production or also to back-up the central heating. This can save another 30% of the costs for heating in addition to the 70% for the hot water costs!
All that is needed is a larger collector area and an accumulator tank to use the solar energy for heating as well. In principle, this is possible with any boiler, regardless of whether it uses biomass or fossil fuels, though it must be coordinated with the control system.
