When you do a job for the 1st time it is always best to ask 1st if you do not know the answer than to fail miserably. I have been researching this for about 3 months and have talked with a Heatas engineer who will come and check my work before i finish. I still dont know everything i need to...

what would you advise to use as the supplier of the stove were of no help at all

Do bsp fittings to multifuel boiler need sealant before i install as it would be easier, or do they seal when tightened?

I forgot i had a multi meter, tracked it back to just what you said Ban all sheds, a loose neutral, cheers for all suggestions.

Hi all, ive been crawling about in my loft on boards that i layed on top of the insulation doing some plumbing when my upstairs lights went out, ive checked that i have lives to my switches but the neutrals are also showing live on my screwdriver electric tester, all but one of the lights are...

Hi Norcon, the link shows error and i cant find it on their website.

Thanks all for the replies, i only want to heat the Rads and to keep it simple, i dont need to heat the hot water and i have only just bought a new cylinder so im not forking out for a twin coil or a Dunsly, Onetap gave me a link which shows easy ways to connect up via flow and return, this is...

Thanks for your suggestions but i do have free wood, so back to the questions at hand.

Hi, im looking to see how a multifuel boiler stove could be installed into my existing gas boiler system, with the minimum alterations as access is a problem to changing most of the pipework before i buy one. i have made a detailed drawing of the existing system and have added a proposed option...

Proposed system

Yes i crossed them over where i extended them and before anyone states the obvious, i did label them before disconecting them, they went back exactly the way they came off, if only i had made a mistake hey, i would have fixed it without even knowing it. Thanks again everyone, im sure some of the...

Are you lot just trying to get in a few more pages to get a record or something lol. Job done! i poured water through and to me at least proved the 28mm pipes were crossed when the water came out of the top pipe at the boiler, i then had no hesitation in switching them over. In hind site, this...

Looks like im on my own then, i will let you know how i get on. if it still does not work when i have it all back together i will run your test for the 3rd time Doitall though i dont know what is expected to have changed though by this time the 28mm pipes may be swapped over.

The problem is the pipes go through the chimney at 45 degrees almost side by side, by the time they get to the top they are front to back and are boxed in, i cant tell which is which. Can someone please tell me why pouring water down the 28mm pipe from the bottom of the cylinder wont prove that...

Any more pics will have to be front or back of the house lol, i have given pics of every bit of viewable pipe. Upgrademe's diagram of how the 28mm pipes are connected to the wrong ends ie flow and return has been the consensus since about page 10! Yes we have gained more of an idea with the...

Port B goes to the top pipe in cyl. The return pipe we thought was getting hot was the 15mm which teed off to 22mm towards the boiler, this is capped off. i can only make a reasonable guess as to which of the 28mm pipes is which when it goes through 8 inch of chimney, even so, from this point...

Yes i believe i pointed this out that i had both pipes get hot in different tests. this is why i proposed disconecting the pipes to find out which was which. i was told after these tests i needed to find out what was happening at the boiler, this i have now done, so what now?

ive done all the tests with the pump off and ive traced the pipes to the best that can be done by eye other than under the boiler, i have had 2 carpets up and been through 2 access holes to be blocked off by brick walls. if ive missed some new tests somewhere then what are they?

i've already put the 2 pics on my last drawing showing the capped off pipe. At the moment i have the gas fire out, if im going to do any tests i need to do them now because i need to put it back for my heating and hot water.

Thanks Doitall, at last an explanation i understand as to why testing with the pump on does not work, this could have saved me alot of time had i understood this earlier. Heres my solution to figure out which 28mm pipe is which, i will close off all rads, water tanks and valves, drain the...
