Hep pipe near boiler....

[limerockconstruction]

Hi Guys - new to this part of the forum I hope you can help...

I've had a few issues with a plumber recently on a boiler instal. Longish story, but i've had someone else come in today to start finishing of some of the other work, new rads and relocated rads etc.

Anyhow, he's pointed out a couple of what he sees as problems, not massive but all add up I suppose;

He added a magnaclean without cleaning the system
Left a lot of hep pipework on show, and not levelled in at all, and left off a lot of clips (hence slacking?), ditto with the condensing pipe
One I was most concerned with - he has run hep pipework in very close to the boiler - the new plumber has mentioned that he doesn't think that Hep pipework should be run within 2 metres of the boiler.

Any help would be appreciated.

old Hep (grey) couldnt be connected within 1M of the boiler but the newer stuff (white) may be able to be connected closer all depends on which model the boiler is some manufacturers actually specify this in the installation instructions, have never heard of the 2M bit though

some boilers its just the heating pipes.

Its a viessmann if that helps?

I thought he said that the 2m rule was something to do with worcester? (may not be 100% correct)

 

[ianmcd]

No modern Worcesters say min 600mm as said I have never heard of a 2m rule,Hep say as long as the boiler has a pump over run and an internal overheat stat then the pipe can be connected direct to the boiler unless the manufacturer of the boiler states otherwise, just call HEP and tell them the model of your boiler and they will advise you

Any make of plastic pipe (PB or PEX) will reccomend a distance in their installations, but the boiler manufacturers installation instructions should take preference.

A number of years ago Potterton kept having issues with their Suprima boilers and plastic pipe, they went from 1 mtr of copper to 3 mtrs.

Some oil boilers said not to use plastic at all. So always check in the boiler manufacturers instructions.

Hmmm, i'll try and have a look, seems like this isn;t too much of an issue (I did just google the instruction guide and tried to word find, piping, copper, plastic etc. but didn;t find the answer!)

Is the magnaclean thing an issue?

So your first installer was incompetent enough for you to call someone else to rectify his work. Then you go on a forum to verify what the second installer has to say about the first.

Reminds me of the one about the lady who swallowed a fly.

Nope - you've got it wrong - his incompetence was mainly around his ability to turn up on the job in the first place, then to turn up without the boiler because his account was on stop, i then had to go and pay for it for him, then there was a problem following the install where he left the house un heated for 2 days and went AWOL......like I said its a long story. And as I said before the other guy wasn't in to rectify, he is there to finish the rest of the job that I can't get the other guy back to do.

He has pointed out a couple of things he felt should have been done differently, why should it be unacceptable for me to check this on a forum?

 

[Tibbot]

Not suggesting anything unacceptable. How can anyone be in a position not to accept your inclusion on a forum?

Why the need to question it then? I don't understand, I assumed posting in the Plumbing section of this forum would be a sensible place to seek advice as I have some conflicting information......

I was pointing out that the person you've employed, after the person before let you down, doesn't seem to fill you with confidence.

in an ideal world the magna would have been fitted during the flush with x800 whilst the old boiler was still in service. I have had great success using this method. So I add x800 with magna/tf1 on working system, pump on 3 gradually increase flow temp from a lower than normaland then shutdown all rads bar one then open another shutdown so each rad gets the individual x800 treatment. Then re-open all and let the x800 run round the whole system drain this off after a few hours. Refill adding f3 and leave this in for a week on the old system and boiler. During this week ensure that the magnet is cleaned regular as it will be picking up quite a lot still. Then on change of boiler day you hopefully have a nice clean system.

So your new guy is perhaps saying this, all he has done is now subjected your new boiler to the carp that it didn't really need to see. Viesmann state in there marketing that there waterways are not as susceptible as others in this area so you are lucky in your boiler choice. I have seen the cross section of this boiler and the waterways are quite large in the hex

Seems a better way of pointing it out - I am reasonably confident with him, but I was with the first chap as well, I just want to make sure that what I'm paying for is leggit really - gas is one thing that makes me nervous. Its hard when the information you get conflicts.

Ultimately it seems that there is nothing terribly wrong with the way it has been installed apart from the pipework looking a bit of a shambles
