My sister has just bought a small country cottage on a hill which is on mains water but due to poor pressure in the mains a system of pumps and gathering tanks are used to get the water up to the property.This provides adequate pressure on the cold water but we need to improve the HW system and this is where the problems start.
Currently the HW system is a conventional indirect cylinder heated by an oil boiler.The header tank is situated on the first floor landing so flow to the taps downstairs is pretty poor. My sister would like to install an upstairs toilet so we need more head to get HW up to the upstairs.
It would seem obvious to raise the header tank to the loft space but the cottage is so small that the space in the apex of the roof is tiny - not nearly enough to accommodate a normal sized tank. In normal circumstances it would have made sense to change to a pressurised HW system such as a Megaflow or perhaps a Combi but because we're receiving the cold supply via two gathering tanks and two pumps it's unlikely that any sort of pressurised HW system would be a success. The cottage is also so small that there isn't really much room for a Megaflow anyway.
The only solution I can think of is to locate a 'string' of 4 gallon header tanks along the apex of the roofspace. There is JUST enough room to sit one of these between each pair of joists all the way along and I was reckoning we'd need about 8 of these tanks to provide a half reasonable amount of storage.
My question is simplE really - would a string of interconnected little tanks work? and what is the best way to interconnect - ie two tank connectors on each tank linking no1 to no2 and so on - OR possibly a run of 22mm pipe with a series of tees and each tee going into one tank connector in the bottom of each tank (a bit like a manifold) Hope that makes sense!
I realise this is a rather daft - even desperate- solution but these little tanks are fairly inexpensive so it's more a matter of time spent linking them together.
Any suggestions lads / lasses?
