I have an S-plan heating system in which the 2 motorised valves are failing to switch the boiler on. They are both returning about 40 volts when switched on.
Currently my heating system is set up to always have hot water on when heating is on but I would like to fix it so that they can both be switched independently.
Any help would be appreciated, even if it is just to confirm that the valves were probably from a "bad batch".
