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.

Are you certain about that?

Yep.



There are no mention of boiler connections and none are shown....

An indirect version can be specified, with either Part L or quick
recovery
coil.

Not mentioned on their web site that I could see. Do you have a
reference for that and the price?

Contact them. Price? A long time ago but it was cheaper than a Megaflow.
The combi was the same price as a system boiler. The water section of the
combi just replaced a noisy space taking power shower pump, and saved
money
again, giving a higher pressure shower.

I have used cheaper combi cylinders, with smaller tanks, "and " the cold
water was taken off the combi tank too by cutting a hole in it us fitting a
tabk connector. Most using combi cylinders have the cold off the mains. I
ran a 22mm cold water mains pipe to the combi cylinder (somnetimes called a
Fortric). A 3/4" brass ballcock was fitted, so the fill up was very fast.

Look at it this way. An unvented cylinder is a mains pipe in and a hot
draw-off out. This method is the same except it has an air break in the
mains pipe. It can still take the full flow of the mains pipe.
