Rinnai Product Brochure

Rinnai Product Warranty



Flat Plate Solar Systems consist of a ground mounted storage tank that is installed separately to the collectors mounted on the roof. A small pump circulates the water from the cylinder through to the collectors to absorb the maximum available solar energy.

Solar Collectors mounted on the roof absorb the energy from the sun and heat cooler water that flows through pipes just beneath the surface.
