Because I live in a cottage with the corresponding low head for theDHW, I've been pondering for some time on the idea of converting thehotwater tank to a Heat Bank. Before anyone jumps in with the pumpsuggestion, I am under pressure from SWMBO to supply hot water to ashower and 2 taps at a considerably better flow than at moment - egflow at mains pressure would be liked!I've been reading the DIY Wiki entry on this subject and realise thatstratification control is an issue and would appreciate any input fromanyone who has undertaken this as a project.A couple of questions as starters :1 I've seen heat exchangers for combis advertised on Ebay - arethese the sort of heat exchanger one would use ?2 I take the tank is left vented to the atmosphere via a header tankbut that the working fluid is a closed loop viz. an unpressurised CHsystem.Any comments would be appreciatedRob

Another pointless exercise.

Total nonsense. Better if integrated of course. When the compensator is in the room stat circuit it works well.

It is clear, as an amateur, you haven't a clue about thermal storage or boilers.
