Flat-plate solar thermal collector
The auroTHERM plus VFK 155 flat plate collectors, manufactured in Vaillants purpose built factory in Germany, have a toughened 3.2mm thick glass for improved durability, and special anti-reflex coated glass for excellent solar transmission.
The collector consists of a laser welded copper/aluminium grid with a high selective absorber coating and improved 40mm rear insulation. The whole assembly is encased in a black ionodised aluminium frame for a neater appearance.
The collectors are available in two models that can be connected in series in horizontal or vertical orientation to suit the available roof space. An extensive range of accessories are availably for pitched or flat roof installation, with the added option of in roof installation flashings means that the flat plate collector can be fitted in virtually any situation.
The auroTHERM plus VFK 155 and auroTHERM VFK 145 are Solar Keymark approved and therefore qualify for grant funding where applicable.
