copper cylinder removal

[princeknight]

hi

removing old system boiler, replacing with combi.
exisitng copper cylinder has 6 connections, hot water, cold feed, central heating flow and return, and another 2x22mm pipes, i guessing these are secondary heating zone? what to do with this pipework when removing and insalling combi.

is it a primatic?

sounds like a twin coil cylinder, do you have a back boiler, aga or a rayburn there as well as an oil/gas boiler?

 

[david williams]

or solar /heat pump??

 

[princeknight]

no back boiler, no oil burner either, no solar panels. it has a system boiler wall hung natural gas, dont know which make, all makings have worn off and no data badge., has only one three port mid postion valve.

Do the fitting on the cylinder that the two pipes are connected ,look like they came with cylinder or added
The cylinder may have a secondary heat exchanger in it,to provide heat to somewere else or pipwork could have been pre run so maybe another heat source could be added later,just going to have to trace pipe runs

pipes have not been added. have sorted the installation, identified the heating flow and return, linked together. cold feed and hot water disconnected, the secondary pair of 22mm pipes, just linked them also. ran boiler, everything running A okay. problem trying to trace second pair of pipes was that there was hardly any room to swing a dead cat in. these clients just moved into property and had ALL SORTS of crap everywhere. but thanks guys for all your help... cheers
