I am changing my hot water cylinder as the capacity is low .I am putting a new cold water tank first (high in the attic) and putting 2 hot water cylinders also in the attic. What is the MINIMUM height between the level of water in the storage tank and the bottom of the cylinder?
thanks

Right now I'm more concerned about the load you intend placing on your roof timbers than anything else. I'd suggest you get professional assistance.

Please amplify the question in your third sentence. That is to say what are you actually asking?

Cheers
