Due to very limited loft space I want to fit the smallest possible header tank on my new hot water system. It feeds the hot taps in a 4 bed house, but not the cold ones. Can I use an 4 gallon tank or is there some Bylaw or Regulation that demands a bigger one? Does the 4 gallons refer to the total size of tank or the capacity to the nominal waterline?
I guess the risk is that a water demand of more than one tap or a fast bath tap will rapidly deplete the header leading to low pressure and maybe drawing air into the cylinder but is this 'against the law'?
A direct mains pressure system without a header is not possible in this case.
