The COMBI solar systems were designed and developed for the cases in which there is simultaneous need of domestic hot water generation, space heating and swimming pool heating.

The production of the NOBEL COMBI forced circulation solar systems is held in two self-owned ultra-modern autonomous facilities of verticalized production lines, which are equipped with robotics machinery.
More than 100 highly skilled employees . are employed in the said facilities. The company holds ISO 9001:2000 certificate for the design, production and trading of solar & electric water heaters.

The production processes and the raw materials used are eco-friendly. The final product is 100% recyclable.

The quality of the produced products is guaranteed both through strict quality controls during all the production stages and measurements executed by esteemed laboratories in Greece and abroad.

Produced with the most refined raw materials , always according to the international standards, they hold all the certificates which guarantee their quality.

They save energy all over the year , even in areas with very low sunlight hours, in which case the water is preheated, something that contributes significantly to the reduction of the conventional energy consumption

The NOBEL COMBI solar systems consist of: the high quality sun selective Apollon collector, with external one piece aluminium trough of special naval aluminium alloy, robust construction which ensures perfect tightness, double water storage tank of cold rolled steel, with a double internal layer of enamel, baked at 860 °C according to DIN 4753, external housing of special PVC &ABS high resistant caps of excellent aesthetics and the hydraulic kit, which is equipped with all the necessary safety devices & accessories for its smooth operation and performance optimization.
Ecological thermal insulation, double anticorrosion protection against electrolysis.
The automations of the system constantly check the temperature difference between the solar collectors and the storage water tank and send orders accordingly, in a way that the constant hot water generation is ensured, always according to the system settings. The differential thermostat is electronically programmed to control the differential temperature and is equipped with buttons and a screen, in which parameters and messages are displayed.

They are also equipped with:
• Anti- frost protection for the closed loop.
• Overheating protection of the closed loop.

In case of non-adequate solar radiation, there is the possibility of function of an auxiliary energy source.
