Independent and integrated solar systems from Zane Solar Systems Australia Zane Solar Pool Heating Australia Zane Solar Systems Australia supply a wide range of solar systems. The Zane solar system pays for itself in just a few years. After the initial setup cost, the ongoing running costs are minimal as the heat is provided free from the sun. A Zane solar system can be installed either as an independent system or an integrated system. Independent systems In an independent system, the pool water is pumped directly from the pool to the solar absorber on the roof and then returns the heated water back to the pool. Independent systems require the pool builder to plan for solar, or to have the professional support of a Zane dealer from the initial stages. Independent systems are simple to install and do not interrupt the filtration system. Integrated solar system An integrated system involves diverting the flow of water after the filtration system. Generally a secondary pump pushes the filtered water up to the solar absorber on the roof and returns the heated water back to the pool through the existing pool water return lines. An integrated system can be easily retro-fitted without affecting any other part of the pool structure and it uses the filtered water of the pool to ensure that clean water is sent to the roof absorber.
