All Sun Ray water tanks are made of long life marine grade stainless steel. Stainless steel acts as a natural barrier to corrosion. Marine grade stainless steel is used in marine environments and is more resistant than household stainless steels. This is the reason why Sun Ray's stainless steel solar hot water systems do not require a sacrificial anode and maintenance free.
A lot of NON Sun Ray solar water heaters' tanks are made from mild steel with vitreous glass lining which exposes them faster to corrosion once the anode has been mostly consumed.
Because of the superior qualities of Sun Ray's marine grade stainless steel solar water heaters, your system will last for a very long time.
Sun Ray has developed the Twin Pipes System. It drastically improves the performance of hot water systems. It works directly on the internal water circulation in the thermosiphon, so as to make the squeezing of the cold water (used to fill panels) happen at the bottom of the tank and the squeezing of the hot water happen at the top of the tank. That way it creates less water turbulences and optimizes the hot water capacity of the tank.
The Sun Ray philosphy is to provide to his valuable customers the longest life duration, to secure the return on investment of each consummer. It is the reason why Sun Ray manufactures all his tanks in marine grade Stainless Steel, cover by Clorbond sheet from Bluscope australia. The Solar panels in marine grade aluminium casing is connected to your roof with anodized aluminium assemblied with SS fastening screw as well.
