Hi
I've got to gain space in our small bedroom so I want to put the hot water
tank in the loft, how high above the top of the hot water tank should the
water surface of the cold water tank be. Has anybody got any links to
sites
with cold water tanks which will fit high up in the ridge - I've googled
but
can't find anything.
Any advice welcome - ps can't afford to change from the current open
vented
system ATM

Have the kitchen tap off the mains. For the hot and cold water for the rest
of the house use one of these, as it fits nicely in the loft.

You can take the shower off it The cold taps can be taken off it and the
hot taps too giving good mixing at the basins and bath. It is heated from a
normal system boiler. It is less than 6 foot high and takes about the same
amount of space as Megaflow. What is gives is high flow at atmospheric
pressures. All the
taps, except the shower mixer are low pressure. The kitchen mixer has to be
high pressure cold low pressure hot.

Cheap and highly effective, no cold tanks or high pressure cylinders that
may blow up and needing 28mm blow-off pipes. It can go in the loft out of
the way.

Then, when money is available, best to buy a condensing combi and only have
the shower off the combi water section to give a high pressure mains fed
shower. The shower is the only draw-off that requires high pressure, the
rest need "flow". The CH part of the combi will be the same as a normal
system with 3-way valve heating the cylinder and the radiators.
