Overview

The auroTHERM plus range of solar thermal systems, area renewable technology range which can deliver up to 60% of your annual domestic hot water requirements, by installing premium flat plate collector panels on the roof of your property, which are connected to an indoor pump system, hot water cylinder and system boiler.

The auroTHERM plus range builds on all of the fantastic features of the auroTHERM range, and provides a more advanced solar thermal flat plate model.

The auroTHERM plus collector panels features toughened glass for improved durability, and special anti-reflex coating for excellent solar transmission – which creates exceptional performance. The collector panels also provide a sleek and subtle finish, being encased in a black anodised aluminium frame for a neater appearance on the roof.

Like the auroTHERM range, this advanced range can be used in vertical or horizontal installations for in roof, on roof or using a flat roof configuration.
