Rinnai 5 Split Solar OIM
OPERATION PRINCIPLE
Split solar hot water systems are designed to have the solar collectors (either at plate or evacuated tubes) on the
roof and the storage cylinder installed at ground or oor level.
The system comprises a hot water storage cylinder, solar collectors, pump, controller and temperature sensors,
and either gas or electric boosting�
Water is pumped from the storage tank to the solar collectors when there is enough heat available from the sun�
The solar controller utilises information from the temperature sensors to manage this process�
Supplementary heating is utilised if insucient heat is available from the sun (such as during cloudy or rainy
weather or during winter months) either via an electric heating element(s) located inside the storage cylinder or via
an in-line gas booster located external to the storage cylinder�
Further detail on the system operation is included in the manual supplied with the controller�
The following diagrams illustrate the operation of the system as with both electric and gas boosting�
