no, the "boiler on" light is on and that`s it.

He had it on 1 red, 2 black and 3 grey. I put it on 1 black, 2 red and 3 grey. Mine sounded better than his when i turned it on and off. I have now put it on your way. Nothing has tripped out. CH and HW is on, the boiler is on but it hasn`t fired up.

He put a new stat in and didn`t have his glasses on, it was dark, so not 100% sure. I know it sounds daft, but we took out the old one and wired it exactly the same as the new one, number for number. When we changed the stat we never touched the junction box, we just re-wired it inside the...

how do i check them. And on the boiler stat the 3 wires are black red and grey. One the boiler stat control there are numbers 1, 2 and 3. Do you know what colours go to what number ?

if i turn everything off, i can`t turn the boiler on. If i turn the HW on, the boiler wont come on. If i turn the CW on, the boiler comes on. If i turn both CW and HW on, the boiler stay on, but because it`s warm here with me keep having to boil water, the CH is to warm so the boiler light is...

No. 1 is live

You would think wouldn`t you, but with just the HW on, the boiler wont even start, no lights, nothing.

Yes 20 is live too

yes, no. 18 is live

No, there is no room stat. All of the radiators have a temprature control on them.

This is the wiring for my heating system as best as i could do it. 1. is top left through to 12. top right. 13. bottom left through to 24. bottom right. As shown on the previous photo shown on here. I will start with 1. then the colour of the wire then what it goes to. 1. RED - TANK 2...

if i could afford to get someone in, i would. But as it is, i have to do it all by myself.

Hi, i have checked my wiring with that one and it dont match. Here is what mine looks like http://i231.photobucket.com/albums/ee149/habbyworld/001.jpg On the top left of the pic, 3 lots of wires going in, the top white is the pump, the middle black is the port valve and the bottom white is...

ok ok, keep your hair on.

when i have just the HW on, the boiler goes off. I have a Baxi solo 2 pf.

if i turn the ch off, nothing will work.

if i turn the CH off in the airing cupboard, it switches off the boiler down stairs.

i dont think the boiler is faulty since it was happy enough just heating the HW. As soon as i turned the CH on, that`s when all hell broke lose.

the banging sounds like it`s coming from inside the pipes, i have checked everywhere and the pipes are not banging agains anything ?

so why do all the pipes make so much noise, banging and hissing and almost sounds like gurgling going through the pipes. i have bleed the radiators and turned the air bleed next to the hot water tank in the airing cupboard, there is no air coming out of any of them.
