Rinnai’s Flat Plate Solar Systems use highly efficient aluminium fin solar collectors. The system consists of a ground mounted storage tank that is installed separately to these collectors. The collectors are mounted on the roof and have minimal impact on the aesthetics of your roofline. A small pump circulates the water from the cylinder through to the collectors to absorb the maximum available solar energy. Rinnai have been a trusted brand for over 45 years who design their products with the environment in mind.
