solar water heater--domestic solar water heater

Solar water heater: Solar water heater systems can be a to generate hot water for your home. They can be used in any climate, and the fuel they use-sunshine-is free. We have CE, CCC, ISO9001:2000, Solar Keymark certificates.How They WorkSolar water heater systems include storage tanks and solar collectors. There are two types of solar water heating systems: active, which have circulating pumps and controls, and passive, which don't.Most solarsystems require a well-insulated storage tank. Solar storage tanks have an additional outlet and inlet connected to and from the collector. In two-tank systems, the solar water heater preheats water before it enters the conventional water heater. In one-tank systems, the back-up heater is combined with the solar storage in one tank.The splitpressurizedsolarwater heaterincludes five parts as follow:1. Solar collector 2. Water tank 3.
