A close coupled system is where the Storage Cylinder and the Solar Collectors are coupled together and the installation is on the roof.

Rinnai Close Coupled Solar System use a 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 for a pump.

Supplementary heating from the electric element will generally turn on overnight to bring the water up to temperature if insufficient heat is available from the sun (such as during cloudy or rainy weather or during winter months).

Features

• Low heat loss due to greater insulation
• Supplied standard in Titanium colour
• Wide range of Colorbond® colours available including
  Silver Prestige. Ask your Wollongong Water Tanks consultant for the full colour selection
• Choice of two selective surface Collectors

Benefits

• Technically very efficient, economical to install and low maintenance
• No recirculating pumps and pipe runs – reducing heat losses and improving running efficiencies
• No electricity required to operate pumps to recirculate the water through the panels
• Space saving in that it eliminates the need for a storage tank at ground level – ideal for courtyard
  homes or small blocks
