Hi all,
My mates recently bought a new old house and has had extensive work done including new bathrooms etc. We've got a few questions about the hot and cold water distribution. The house is supplied by cold water at around 3 bar, so decent enough pressure. The way it's set up at the moment is the cold for the kitchen sink and outdoor tap are fed off mains pressure, but everything else is fed from a cold water storage tank in the attic, so it's a vented gravity fed hot water cylinder. A pump is installed after the hot water cylinder which pumps the hot water and the gravity fed cold water to most of the house. Cylinder is heated by an oil fired system boiler.
First question is, would it theoretically be possible in the future (years) to have a high pressure hot water cylinder so therefore mains pressure hot and cold water throughout with an apparent mains pressure of 3 bar? Not sure what the flow rate is but definitely doesn't seem too weedy based on the kitchen and outdoor tap, anyway could always have a whole house pump fitted.
Secondly, when I say there is a cold water storage tank in the attic, there's actually 3 of them, and the way they're set up is only one of them has a mains cold supply into it, and the 3 are just linked by the feed pipes at the bottom if that makes sense. Now this seems very unhygienic to me as only one tank would really have the water regularly replenished and the other 2 would be fairly stagnant, thoughts on this?
Would a short term solution be to just do away with the extra 2 tanks and have just the one? And how hygienic would the water be from just one tank? Its not clear why its been done like this, perhaps the original tank wasn't big enough so two extras have been bodged on over time with more bathrooms or whatever, and I can't remember what the size of the tanks are but they're not small. I believe that a single tank would need to be 200-250l, is that correct?
Thanks for any replies!
