Thanks to their highly selective absorber they are efficient throughout all seasons

Rock wool insulation brings about reduced heat loss back to the atmosphere.

Harp absorber construction ensuring low flow resistance and economic energy consumption

Durasolar® P+ glass used on the front for optimum absorbtion of solar radiation and endurance.

UV resistant materials guarantee long lifespan

Certified by DIN CERTCO for compliance with DIN EN 12975:2006-06 and Solar Keymark








Water heater SunSystem
SUNSYSTEM family of solar water heaters

Water tank of low-carbon steel, coated with titanium enamel for a long service life.

Rigid PU insulation for efficient heat conservation

Heat exchanger coil / coils for use with solar collectors or/ and another heat source, i.e. BURNiT boiler.








Solar support systemSolar support system

Two versions available: for inclined and flat roof.

Durable lightweight construction of Aluminum withstanding severe climate conditions.

The support structure is resistant to wind speeds up to 150 km / h and snow mass up to 1.25 kN / m² according to ENV 1991-1-3 and 1991-1-4








The necessary fittings, expansion vessel, and heat carrier.

Solar station ensures forced circulation of the heat carrier fluid, performs basic system measurements, safety and maintenance functions. Employs energy efficient solar grade Wilo pump, designed to withstand the demanding conditions of a solar system. Smart insulating case of durable elastic EPP ensures thermal insulation of all elements and neat appearance.

Solar controller with pump speed control, drainback option, and 4 temperature sensors monitors the operation of the entire system and controls the function of the solar station for maximum yield.

Cross fitting 2 in 1 with sensor housing and manual air vent.

Propylene glycol is used to ensure flawless heat carrier even at negative ambient temperatures.

Expansion vessel. Fixed bladder expansion vessels are designed to absorb the volume increase when temperature rises. Working temperature tolerance -10°C +110°C. The products comply with European Directive 97/23/CE.











Connection schemes :




Attention! All schemes are examples.
It is recommended that sizing and connection of your system be carried out by an authorized service professional/specialized service shop.
