Vaillant, a leading heating technology business company, has recently incorporated high performance and high durability thermosifon systems, even in environments with high corrosion levels, in its solar energy product range.

Its collectors include an absorber with selective coating, insulation in the back and side, as well as in the 4 mm thick security glass and the aluminium housing. The accumulator is made in vitrified steel, double coating and high insulation thickness to reduce losses in winter. As for mounting structures, they are specifically designed for quick and simple assembly, both for flat and sloping covers, which can adapt to any type of roof. All feature anti-corrosion paint, even for marine environments.

Three models are available, to select according to instalation needs: auroSTEP pro 150 (installations with domestic hot water consumption of 2-3 users), auroSTEP pro 200 (installations with domestic hot water consumption of 4-5 users) and auroSTEP pro 300 (installations with domestic hot water consumption of 6-7 users). Furthermore, all models can incorporate an electric resistance of 2 or 3 kW CE-approved with security thermostat, which avoids uncontrolled heating if the regulation thermostat fails, reveals the company’s press release.
