3. Certification 2733 to AS2712 2 INTRODUCTION Traditional solar water heaters consist of two separate items a collector panel collects the radiant energy from the sun and transfers it in the form of heat to the water in the collector panel b The hot water storage tank stores the water that has been heated in the collector panel The SOLCO SOLARTECH Genius is unique in that a It utilises a fully flooded collector panel that contains no channels or pipes but instead provides a water filled cavity over the complete collector area b It utilises a design in which the collector panel and the storage tank are fabricated in one piece moulding removing the need for joints seals or gaskets all of which are a major potential source of leaks and corrosion From your water supply cold water is introduced into your solar unit that is installed on the roof of your home or workplace Energy from the sun is then absorbed by the solar panels converting the sun s radiation into heat energy providing you with solar heated water The SOLCO SOLARTECH Genius operates as a oS constant pressure system The main supply coun mier Hume gt water is fed directly into the collector panel via transfer chute located in the storage tank This means that the SOLCO SOLARTECH Genius prevents cold water jetting into the storage tank and significantly reducing the temperature of the stored hot water In independent tests it

24. verage family s hot water usage around 150 litres per day you can expect to have up to 80 of your annual hot water requirements met by your SOLCO SOLARTECH Genius Solar panels operate by converting the sun s radiation to heat energy In other words you should not expect to receive free solar heated water on rainy dull or overcast days As a general rule on clear sunny days with high levels of radiation your SOLCO SOLARTECH Genius will operate at approximately twice the maximum daily outside air temperature For example on a clear day with air temperature of 25 C your water will be heated to approximately 50 C On high solar radiation days your electric booster or other supplementary heating system should be switched OFF particularly during summer Due to its construction and design the SOLCO SOLARTECH Genius will not boil during prolonged periods of hot weather On medium solar radiation days when it is cloudy or overcast the electric booster or other supplementary heating system may need to be switched on The electric booster should be left on for approximately 3 hours without hot water usage to generate maximum stored hot water capacity and the most efficient operation On low solar radiation days it is recommended that the electric booster which is thermostatically controlled and factory set at 60 C should be left on Alternatively if your SOLCO SOLARTECH Genius is connected to another supplementary heating source for example
