USEFUL ADVICE close to 3 bars. In this case, temperature rise in the circuit can cause the pressure relief valve to open. So that this does not happen and to decrease the pressure to a normal value, it is advisable to vent some of the water in the appliance through the bleed valves present in the radiators. -
