The introduction by FAKRO
of its SKW in-roof solar thermal system enables a modular approach to be taken using FAKRO roof windows of the same size. Systems for 2, 3, 4 and 5 person homes provide up to 70% of a household’s hot water needs using low iron, toughened, optically efficient prismatic panes. Heat is transferred to a copper absorber sheet and a water / glycol solution which passes through a dual core cylinder with heat exchanger. Of four low profile panel sizes, the lightest weighs just 21kg and by using roof window flashings panels can even be installed with Duet high pivot windows. Suitable for pitches of 15° - 90° (with optimum efficiency between 35° - 55°) a patented fixing system allows site adjustment to suit rafter / batten spacing. Couplings are housed neatly in a specially designed upper cover plate.
