how can i change the valves without driaing the system ? how do you drain a system ?

when should i think about changing the valves and radiators in my house as they were put in when the house was built in 1987, How long does a radiator last ? Also how often should the valves be changed ?

yep, doing black as im board with the white just goes yellow

my towel radiator is starting to rust and paint flake so i plan to strip the paint off ( back to metal ) and repaint Can anyone recommend a suitabel heat primer and heat black paint ?

no one stocks ss cable which is strange, its 2.5 mm, i ahve even called an electrician who would never use ss cable and use rr max can anyone shed any light on this ?

did you get this sorted and get the correct cable ?

hi can anyone advise me where i can purchase the h05 ss - f cable that my ceramic hob requires ??

established 1N, the next issue is the cable that samsung state to use - H05 ss - f ( 180 degrees ) i have been everywhere, even electrician wholsalers who dont stock this and find is strage that its required do i actually need this ? or is a 85 degree one ok which seems comonly used

i dont know the current ceramic hob is wired with the 6 wires, ( although this cable came with the original hob ) the over would plug into a 13 a socket

Hi i have just purchased a samsung ceramic hob and oven, the problem is how do i know if the hob is 1N or 2N ?? The hob i am replacing is an idesit and i was going to use the cable from that to wire the new samsung, I have checked the cable and its a 6 wire cable can anyone help me...

they are actually all in a case ( backing part from a plug socket ) i think the best thing for me to do to keep it neet and tidy is to track the grey wire from the honeywell valve and also track from the thermostat as everything is easily accessable, connect these and just run a new wire from...

thanks for the info, so - grey wire is not from the boiler thermostat, its from the honeywell valve ? how do all 3 connect together ? ie = thermostat to valve to HW off ?

so would this be correct - if i have 3 conductors on the boiler thermostat ( and an earth ) i connect the grey wire to the HW off terminal on the drayton lp522 ?? would this then mean that i have to change the timer to P ( pumped ) would this also mean that if i put CH on, the HW...

so what do i connect and where ?

that looks complicated and id be worried about messing it up ?

currently i have teh timer set @ G and its heating the water ok, should i change this to P even though the hw comes on with CH ? When i put the timer on, all wires were connected together etc by electrical blocks, there is no box so to speak ?

This all depends on how easy it is to run a new cable from the Drayton and from the HW cylinder thermostat i like the idea of the above is it as easy as running 1 wire ?? would this mean i still have a GRAVITY SYSTEM ?

sorry, just checked sm400 again and it has heating off terminal, not water off

its a V4073a just looked at the switchmaster 400 and it does have a terminal for hw off but no wires are left spare,

further to this, i have spoken to drayton again who think i have a gravity system as i cannot have the ch on without the hw ?
