What is a Closed Couple System…?

A close coupled solar system is where the storage tank and the solar collectors are coupled together and the installation is on the roof.

Rinnai close coupled solar systems use the thermo-syphoning principle (i.e. hot water rises because it is less dense) to circulate the water through the collectors and then to the storage cylinder without the need to consume energy.

Supplementary heat is available from an electric element booster if insufficient heat is
available from the sun (such as during cloudy or rainy weather or during winter months)
