Alternative energy path

Thermal solar panels Rehau – Solect of Rehau heat up the water safe for daily use for ex post facto, if it is necessary to use gas or electricity and are based on a simple principle: capture from heat of the Sun in order to make the most for the heating of the water and the integration of the installation of heating.

The thermal use of solar energy technology has reached a maturity and reliability such that today counts among the most rational and clean methods to heat the water for domestic use. Solar radiation, despite its low density (which is 1kW/m² only in the days of serene sky), is the energy source more abundant and clean on the face of the Earth. A square meter of solar collector can be heated to about 45 - 60 ° C between 40 and 300 litres of water in a day; efficiency varies depending on the climatic conditions and the typology of the collector.

The solar collectors of Rehau, perfectly integrable both in new buildings and in rehabilitation work, guarantee maximum flexibility thanks to the large number of possible variants which allow and the principle of the modular technique of components. With the use of Rehau – Solect systems, solar shortwave radiation is transformed into heat in the collector, while the transparent cover and the absorber (covered with a layer of high-quality) Act as Chamber of mirrors to prevent the passage of rays of wave long abroad.

Through a termovector circuit, and thanks to the use of a mixture of water and glycol that protects the interior of the circuit against Frost and corrosion, the retrieved heat builds up in order to satisfy the demand for hot water. Electronic regulation ensures that the solar circuit pump works only when the energy from the collector has accumulated in the accumulator.

Through the correct sizing, Rehau – Solect solar collectors, which cover up to 30% of the energy demand of the year, combined with radiant heating for floor, wall or roof of Rehau.
