Hello
I'm in the process of having to run a new heating circuit for my downstairs rads as the existing pipes are buried under concrete floors and their developing leaks.
I could T-off from the upstairs circuit but the way the pipes are run its actually not too much hassle just doing a separate circuit back to the pump cylinder etc. So I'm going to run the new circuit and take the opportunity to zone off up / down stairs circuits - plan is to get a professional in to do the final connections in the airing cupboard.
I want to do my homework and take the time to understand the job properly so I managed to trace a lot of the pipes and I think I figured a lot of it out. I am sure much more clever people on this forum will correct me....
I think I have what is called a Y plan, vented indirect system which uses a heat only boiler.
I'm trying to figure out some of the pipes that lead away from the cylinder following the numbers on my diagram do I have this correct?

- Hot water to the kitchen and bathroom taps around the house
- Unsure, but I am guessing that this will connect up with the return from radiators and go to the boiler and loop back round on pipe 5?
- The red highlighted pipe I couldn't physically reach around the cylinder to trace but my best guess is that this connects to the bottom of the cylinder at the back feeding in cold water as hot water is drawn from the top.
- Hot water going out to the radiators.
- Heated water from boiler? which before that came from radiators (which came from #4) and came from hot water cylinder (which came from #2)?
Does that mean the pressure relief valve only allows water to pass downwards when pressure gets too high, a bypass? - Similar to #1 but just the cold un-pressurised feed to taps around the house
- Same as #1
- Same as #6
- Mains cold water feed
