The tanks of solar heating systems, Boiler, Sollerman are installed in solar heating systems that use flat solar collectors for water heating. They are manufactured according to the European standard EN 12976, from sheet metal EN 10130 AI 1998 DCP.

The insulation is made of ecological polyurethane 53kg/m³ with a thickness of 50mm. They have anti-corrosion protection of liquid enamel according to DIN4753-3 with thermal treatment at 850°C, Double Titanium Glass, and a magnesium anode according to DIN12438-2.2, for protection against salts and electrolysis.

The electric resistance is 4KW with an adjustable safety thermostat. The external surface cladding is stainless steel, providing high resistance to weather conditions, offering a steady and immediate supply of hot water.

The design is functional and allows for easy and quick installation, while it is constructed for space saving.
