Plumbing Question

Moving vented hot water cylinder into loft.

I am wanting to create some extra space in my airing cupboard so I am wondering if it is possible to re-site the cylinder up in the loft. The storage tank is obviously up there on the joists already. Can this be left where it is or does it need to be moved as well? Thank you for help

With a gravity hot water system, the water pressure from your hot taps is in direct relation to the difference between the water height in your Cold water storage cistern and the inlet point on your hot water cylinder, otherwise known as head (.1 bar per meter head I,E 10 meters =1bar)So even if you are able to raise the cold water tank above the cylinder in the loft, you are unlikely to gain sufficient head to give anything like a reasonable pressure from your taps.
You may be better off converting to a combi boiler, in which case you could get rid of the hot water cylinder AND the cold water storage cistern.
Hope this helps
