• It is made of copper welded with LASER technology and black paint (electrostatically) for immediate heat transfer to the thermal fluid.
• Selective collector surface with additional coating of special chromium and nickel alloy achieving maximum penetration of solar radiation with an absorption coefficient of α=0.95 and emission ε=0.05.

External Cladding:

• Made of anodized aluminum
• ECO GLASS from pre-painted sheet metal

Thermal tank made of 3mm thick steel sheet D.C.P, with two layers of protection from special type Glass enamel (Glass) baked at 850°C, highly resistant to electrolysis and corrosion. Suitable for drinking water.

Heat Exchanger:

• Made of 1.5mm thick sheet metal type Jacket
• Made of enameled pipe for connection to central heating (upon request)

Additionally:

• 6cm thick polyurethane insulation, density 40kg/m3
• Anodic protection, magnesium rod for protection against rust, salts, electrolysis,
• 4kw chrome-plated electric resistance, with safety thermostat for operation with electric power.

It is dual-energy, meaning it can operate in two ways: with solar or with electric energy. This means that inside the water tank there is an electric resistance, so on days with little sunshine due to cloudiness, you can operate your solar water heater with electric energy and always have hot water.

Regular maintenance of the solar water heater optimizes the quality, hygiene, and operational performance, while also saving on energy consumption. For the smooth operation of the solar water heater, regular maintenance by a specialized team is required. The necessary actions during the maintenance of the solar water heater are:

• Checking the level of solar fluids & refilling where necessary.
• Inspecting and repairing the insulation on the local solar pipes.
• Checking and replacing the magnesium anode to prevent the formation of salts inside the solar water heater.
• Inspecting and cleaning the electric resistance.
