Safety group GSE3000 GSE3000 is specifically designed to protect water boiler tank with a power up to 10 kW. This device allows 4 main functions: protect the boiler against excess pressure, this function is assumed by the safety valve set at 8 bar (800 kPa); isolate the tank from the main water supply, this function is assumed by the ball-valve; to forbid the backflow of the hot water inside the cold main water supply, this protection is assumed by the integrated check-valve (KIWA and Belgaqua approved); flush the boiler: in case of need the safety valves authorize the total blowing off of the boiler.
