how to connect secondary return pipe for hot water?

[bluesky]

dear all, sorry for this silly question,i am not good at plumbing really, still at training, i am going to convert a conventional boiler to a combi boiler, there is a secondary hot water on the side top, i am thinking to just connect it with hot water from top of the old cylinder, is this ok? i dont quite know how secondary hot water works to be honest,

cheers in advance

your still at training ? you shouldnt be doing this work then

 

[bluesky]

i had the fast track training, i did spent 3 month in trainging center on plumbing, maybe they did mention this kind of open vented cylinder, but missed this part because my english is not so good, sorry for disturbing you if this is too silly question..

 

[GQuigley67]

i just dont think your competent to install this with your experience plus there is gas to deal with

 

[bluesky]

i googled it, think i can just put a stop at the end at ofcondary return pipe, is this conrrect?

Just leave it alone mate.

 

[GQuigley67]

"im not good at plumbing"

then how can you convert a conventional system to a combi system ? which is advanced plumbing work not for beginers

 

[WHPES]

No No No No No.

Just leave it alone until you have enough training and experience to actually know what you are doing.

Think of the words of wisdom that Alexander Pope once wrote - "A little learning is a dangerous thing"

Is this a wind up?

 

[SimonJohns]

3 month course. !!!!!!

Your more qualified than half of the "plumbers" on here.

Only seems to be a few of us who have completed an actual apprenticeship

 

[WHPES]

I don't think any wind-up merchant would actually post that as they would think it would be far to unbelievable for anyone to be duped by. By my logic it's gotta be genuine! :nonod:

Cut and cap it as far back as you can. Dead legs is what you should look up.

 

[dontknowitall]

If you're still in training, why not test (I mean ask) your trainers?

 

[bluesky]

FFS. Cut and cap it as far back as you can. Dead legs is what you should look up.

thanks tamz, own you one again...

If this property is large enough to have secondary circulation is a combi an ideal replacement?

my thoughts exactly

Never question what a customer wants, they always no best, at least, you get the job of going back and putting in a more suitable system..

 

[GQuigley67]

are you sure its a secondary return and not just a seperate hot feed ?

 

[bluesky]

are you sure its a secondary return and not just a seperate hot feed ?

not sure, might be a seperate hot feed because cannot see a pump for the pipe, i assume normally there is a pump for secondary hot water

 

[mikimac]

Just a small one...who's installing the combi?

 

[mikimac]

Maybe I've missed something but I'm slightly confused...you say you are in training yet in a previous post (hw doesn't work without central heating) in this forum you installed a megaflo & baxi system boiler. Are they GSR trainees now??

Normally but not always. They can work on gravity too. Sometimes found in older buildings.
