Electric and solar water-heater supply and relief system

摘要: Relief system of water-heater and hydraulic system, whereby the cold water inflow pipe (11) is placed above flow level (14) at which spot a multiple-­relief valve (17) fitted introduces atmospheric air in case pressure drop network below pressure, thus maintain fullness water-heater, while same time allowing relief overpressure when it exceeds certain limits. Then, supply directed towards bottom through single-pipe connection. The multiple-relief on network, located upper water-heater. membrane (29) opens safety levels relieves system. (37) there preventing depletion. benefits this invention regards 100% protection offered against due to communicating vessels effect prevention depletion, that may have uncontrollable disastrous consequences. Also no or spring neither inlet nor outlet water, excluding all possibility salt-formation obstruction its operation.
