Thanks do it all. Space not a prob for the cylinder, it will go in the end of the garage with enough space left to fit a car. I'm lucky in that I have a modernish house with an integrated garage that is more than big enough to fit a car in. kitchen backs onto one wall of garage, cylinder...

Thanks all, from the start i have maintained to those that have come and quoted that I wanted an unvented system with boiler and tank in garage, some have talked me away from that, some have offered alternatives. Hence me asking for an opinion. I guess those that talked me away from that...

from the quote Hot and Cold water conversion to sealed system and install 22mm copper cold supply and hot water retern to new cylinder. So mistake in my terminology??

thanks Quote from the second guy include upgrading water supply from 15mm to 22mm from incoming potable water main to boiler.

I've had 4 guys round and to be fair to the last 2 that came their advice and also quotes have been the best. Out of these two first guy said I could probably get away with the storage combi as the increased cost of unvented may put me off. Second guy quoted both before making a...

Thanks for that. Going to ask the guy to requote for 24kw boiler and larger capacity tank.

What about the combi storage option that has been quoted for?

I realise this question has been done to death so apologies for asking it again. I know that the answer in this case will be unvented but I just wanted to have another opinion as I have been given conflicting advise from people who have quoted. Changing the boiler to get rid of the hot water...

ok thanks. im going to try fault finding on the ignition circuit first from the pcb up to the solenoid. i'm assuming that if the solenoid has 240v across it and isnt working correctly then its faulty. If its something inbetween it should be easy to isolate the fault. after that i'll be...

Hi all, Some help would be appreciated. Boiler fires up, then goes out, then fires up again, then goes out, etc etc. I can hear the gas solanoid opening and shutting. before i did out the fault diagnosis sheets does any one have an opinion? Could it be the air pressure switch...

hi. it was the pcb. replaced it and all is well. thanks to everyone who posted on the thread, i've thanked you all individually as well. regarding all the "you're not a rgi, you're just diy" I intentionally stayed away from all the gas workings of the unit. Before going near any of the...

its a 3 switch mate. i think the aps gets its power at the same time as the fan. the boilerover heat stat comes before them both in the wiring flow diagram. i think the stat is ok as there is continuity across it with the terminals removed. what it doesnt have is any voltage going to it when...

hi all, thanks for the comments. i was very gentle with the aps, didnt disconnect it, only removed the air hose from the venturi and gently, very very gently blew into it to see if it was stuck open as someone said it might be. where i am at present is i think the pcb is at fault. i...

all ive done re the aps is gently blow into it to see if i could hear the microswitch.

i'm checking the thermocouples, should there be a voltage going to the boiler overheat cut off? there is one going to the low and one to the high but nothing to the overheat cutoff.

Thanks namsag, i'm sure he would have considered this, if i was to check it myself what would i be looking for? off to google to study pressure switches.

ok, ive got the part number off the pcb, it was superceded by another pcb so thats what ive hopefully got. namsag, When the programmer calls for heat the pump starts up, the divertor valve switches across to whatever is required, the boiler does nothing. When the plumber first looked at...

Right, have spoken to the plumber. This is how i understand the situation. The switched live in the terminal block is not switching, this is not giving the call for heat. He has said even with a permanent live connected into it. it is still not giving a call for heat. He says that he spoke...

it is my boiler. when i said "its not my boiler im asking about" i meant that my original post was asking questions about the plumber. and the only reason i brought up the plumber paying for some of the cost of replacing the boiler was because he said he broke the loom whilst replacing the...

ok do you think its worth looking for the fault or just go ahead with the new boiler?
