WHy do some boilers (most modern ones) have a permanent live feed as well as a switched live feed? What's the difference/benefits?
Most older boilers used to have a switched live, going to the wiring centre/junction box and being connection the the same terminal as the pump live and MV orange.
How do these new boilers wire? - Is it in the same way but with an additional L and N fed from the wiring centre L and N terminals or from a different feed?
