PLEASE KNOW im not trying to put any installers down or offend anyones technical knowledge, just trying to figure this out. Moneys short but god knows, I don't want to ignore safety or any risk to us or the house.
That said, Im talking about saving ££ and doing some of the install work myself. I know some gas guys I called really really didnt want to comment much and wanted to do the whole job if installing a combi, their selves.
HISTORY: 3 bed end terraced home, right now have old Baxi back boiler, feeding heating water and hot water one end of the house up into the landing (2 pipe sys at 15mm) for the upstairs rads and T's off at the boiler to the downstairs rads, under floor (they channeled out concrete.) I want to replace these pipes fed from the landing level.
I want to cap off the first upstairs rad and install a combi (24-28kw) downstairs in a ''toliet only'' small room near the kitchen. Its at the opposite end of the house. That way, hw would be fed with least amount of pipe, the old gas pipe runs that way and is an easy run to the original pipes. Researcing online some people say I can run the water and flu, some not. some say that I wont get a guy ''just to do the gas''.
I understand there are flow considerations, people out there have spent a lot of money becoming approved to do this. Again, im not out to upset anyone.
I can see no updated (2011) info on here. What is legal for me to do and what is a no no (like the gas). I was going to run copper about 3 matres from the boiler, then use plastic.
I have Q's!
1) Why do people like B&Q and Wickes and Plumcentre allow you to buy combis / flues / gas spares etc if you can not do any work, yourself??
2) What can I run pipe wise, irrespective of efficiantcy or rad layout?
3) I live in Bristol, anyone know someone that can advise me or visit, tell me where and what piping to run, incl size, to save ££, test if after hooking up the gas for me?
I understand about flue candescent ''gasses'' have to be vented out and away from anywhere they might cause condensation on things, also that rads have to be balanced and pipes have to be put somewhere safely and tied in properly as to not move etc.
I just want to work with someone as budget is tight, of course, and just paying the mortgage is a big commitment.
Advice guys, be nice and HELP HELP HELP !!!!
