Solar thermal energy - Flat collectors

Flat collector RA 215

Efficiently convert solar energy into heat

Heating costs account for the largest share of energy costs. More than 80 percent of domestic energy consumption is attributable to space heating and hot water preparation. By including solar energy, this cost block can be significantly reduced. With its 2 m² surface it fits ideally also on smaller roof surfaces.

The advantages of the RA 215 flat plate collector at a glance:

Highest solar yields due to blue, highly selective Tinox vacuum coating
Langlebig durch hagelfestes Sicherheitsglas, doppelwandige Alurahmen und dauerhaft dichte Schneidring-Verbindungen
Optimum use of space due to horizontal and vertical installation

more than 525 kWh/m² per year

Use of minimum solar radiation through combination with the Oskar° stratified tank and/or a heat pump
A completely coordinated system with other ratiotherm components

It is more than a normal solar collector and represents an important building block in the overall system for the use of the free solar energy source, whose potential is only partially exploited. Unlike purely fair-weather solar systems, our RA 215 flat-plate collector can capture even the smallest ray of sunlight.

In combination with the Oskar° stratified storage tank or the WP Max-Air hybrid heat pump, additional heat gains can be achieved even at temperatures below 35 °C. The RA 215 flat-plate solar collector is the perfect solution for even the smallest solar rays.

The RA 215 flat plate collector has a meander absorber for easy installation and connection of collectors. Whether flat, pitched or saddle roof, we supply the appropriate mounting material. Installation as a high-quality and attractive facade element is also possible.
