Vaillant launches a new flat-plate solar collector
Advanced solar collection — Vaillant’s VFK 990 flat-plate collector.
Vaillant’s new auroTHERM plus VFK 990 flat-plate solar collectors can be connected in series in horizontal or vertical orientation to suit the available roof space. These collectors have a special anti-reflex coated toughened 4 mm-thick glass. The collector consists of an ultrasonically welded copper grid with a high selective absorber coating and 60 mm of rear and side insulation. As part of Vaillant’s total solar-system solution, these collectors can be used with the auroSTOR stainless-steel storage cylinder, managed by the auroMATIC 560 solar controller. A second coil in the cylinder is connected to a conventional heating source, such as a gas boiler. These collectors come with a 10-year warranty.
