[QUOTE="Evans Electric, post: 501697, member: 1408"] With reference to my ...Right decision on EICR Thread..... we upgraded the board to an RCBO 14 way . Three ways are separately switched for E7 Storage htrs & big Steinel water heater with E7 plus 24hr boost . Bloody thing has a linked neutral in it which knocks the RCBOs out . We jump wired the E7 contactor coil to get the off peak supply on to the boiler . Two DP switches at the boiler , 24hr Boost & Off Peak . I presume they feed the same element in the heater , no info ,,also not our remit to pee about with pressure vessel type thingys . The E7 out from the board passes through the contactor N/O which would prevent the 24hr Boost switch from powering the storage htrs at the same time as the W/Htr . If 24hr is switched ON at night it back feeds through the E7 DP switch . [/QUOTE]
