Solar water collectors fixed in portrait style to gable hipped end of new pitched roof. Photovoltaic modules fixed landscape style above solar water collectors to gable hipped end of new pitched roof.

Solar buffer tank for domestic hot water, 200-litre capacity indirect open vented cooper storage cylinders.

The photo shows the insulated flow and return pipe work, and (red) solar anti freeze expansion vessel. This allows for the displacement of anti-freeze during normal operation and to accommodate anti-freeze under high temperature conditions.

Solar water collectors:
Primary heating to the solar buffer tanks located in the roof void. The Solar Collectors are located on the southern gable of the new-pitched roof. The buffer tanks supply back up hot water to the top floor 8 flats in lieu of electrical immersion heater.
