hi, yes I've just done that and it does heat up as I'd expect, I guess more pressure to pump the water in servicing just the one rad? However I've just now discovered what may be the problem, or certainly may not be helping, the fancy radiator valve is on the inlet side, all my other rads its...

Hi I have one troublesome rad that never heats up at the bottom, unless it's on for hours then eventually it does. Anyway took it off and flushed with hosepipe, put it back on and hey presto was great, heated up straight away and thought I'd fixed the problem. However the next day it was back...

Ah okay, but the N is safe to come down from the ceiling rose, i.e for the light that is being worked on? As it happens I'm trying a no N required smart socket so I'm hoping this works with any kind of N, it uses some little capacitor I'll call it in the rose to prevent led's flickering.

Hi, these switches that need the N (to power the wifi chip), can the N be taken from a plug socket which is closer and easier to route than from the ceiling rose (well i don't have a ceiling rose actually as they are outside wall lights)? I did read it has to be the same circuit but as I...

this is the new switch which from what you guys have said needs to be (right to left) wires 2, 1, skip, skip, 4 from the old unit. its a lamp in my back garden, house was a self build (not by me) so i can imagine they may have just used any old wires to fix it up, the power is from my meter and...

just had a quick test terminals 2, 3 and 5 are all live, terminal 4 only becomes live when the timer kicks in... 1 and 2 produce a link/reading when connected using a multi meter so i assume that confirms they are the L and N in...

the new timer is just how bernard has sketched his suggestion to wire it up, L and N in and same out... what would 3 and 5 be used for then, are they additional switched lives?

this is the whole thing, the new timer is just as Bernard has sketched, that grey wire I've highlighted in blue is what goes up to the lamp holder at the top and yes will take the neutral up there too, no idea what's going on at the bottom though, they have obviously just used red wires for...

Hi everyone, stumbled across this site whilst trying to work out how to replace an old immersion timer that is different to the new one i bought, hoping someone can point me in the right direction. It's actually used on a lamppost rather than a heater, this is just how we found it at the...
