One pipe central heating

[benjamin31]

Hello,
Just a question regarding the pics posted.

It's currently a one pipe system. In order to make it a two pipe system, do I need to cut pipework on the flow and return, pipe up rads, then re connect the new pipework to the existing flow and return?

Thanks for any advice.
BTW I was going to insert an image, but can't sm to figure out how to!

if it's a one pipe system you haven't got an existing flow and return

How would I go about changing it to a two pipe system?

 

[corgiman]

wow thats a question and a half

I am sure someone will explain but I would suggest you get some quotes from some recommended pros

If I could ever work out how to post an image i'd show the picture!!!!

Er, no, not quite.

If you truly have a one pipe system, then you need to add a pipe all the way round the system, so that there's a pair of pipes going to/from each rad.

Depending on the number of rads and your pipework layout, and house contents, and house fabric, the work involved could range from a lot to an awful lot.

The job is for someone I know. The floor coverings are going to be changed, so running pipework, and accessing pipework under floorboards isn't such a big issue.

There is going to be 10 radiators. There's already a pump, two zone valves etc in place, which i'm sure can stay.

Thanks for any advice

This sounds like one of those jobs were it is easier to just start again. Rip it all out. Sell the copper for scrap and run a nce new two-pipe system using polypipe and copper tails.

ESPECIALLY if its a friends. reftro fitting when you are not 100% is just asking for friction.

Looks to me llike a nice fully pumped S plan. Are yopu sure its one pipe?!
And by the way its been maintained at somepoint by BG because the Blue ACL is one of theirs.

Try and take a look at the pipework under one of the rads. If both ends of the rad are supplied from one pipe then tough luck. If each end goes to a different pipe then you are barking up the wrong tree.
