Hot water cylinder linking out

[mthorniley]

I have moved into a new property and have recently pulled up the boards on the landing.

The House currently has a combi boiler and has had a hot water cylinder in the past.

I was wondering if anyone can provide a diagram of how the pipework is usually linked out when changing from a gravity system to a combi system. For some reason The shower in the bathroom has its own hot water supply in 15mm that I assume is linked out in the old pipework. The bath hot water and kitchen hot water are fed from the main 22mm from the boiler.

No such thing really. The hot is fed from the combi instead of the HW cylinder but how this has been done is anybody's guess. Are you having problems?

No problems, just curious. The pipework from the cylinder is still there but some is capped and the others look like they have been jointed. the main reason is that the feed from the shower comes from where the old cylinder was and runs direct to the shower whereas evey other hot tap is fed from the main HW from the combi

Probably just easier to covert it that way at the time. No real hard and fast rules.

Worked it out.
They'd linked the old expansion to the flow and used it as the new leg to the boiler
