Is it possible to relocate our HW cylinder into the attic from its present location in the old airing cupboard adjacent to the bathroom? I'm replacing the old cylinder with a new one at the same time as adding a new pump-assisted shower to the bathroom. The new cylinder will be near to the outside wall of the house with additional insulation around it. There is plenty of support for weight up there in that location. Will I encounter any problems relating to flow etc? Thanks for any advice.

JB,
What about the cold tank? Unvented cylinder? Appears a combination cold tank/cylinder is what you need. More info requirerd.

On Sun, 6 Feb 2005 16:37:29 -0000, "JB" strung together this:
If it's a standard gravity fed hot water system, no you can't. The tank will be above the header tank in the loft which provides the pressure for water to flow through the cylinder, water doesn't flow uphill!
To be able to relocate the cylinder in the loft you will either have to move the header tank to above the cylinder, which would be tricky. The best option would be to convert the hot water system to a pressurised system so it is at mains pressure and therefore doesn't need any header tanks. This requires a fair few addittional parts and some alterations to the system in general, and aso you may need to upgrade some existing parts to cope with the increased pressure.
Many thanks for the sound advice. My brain is not working well today! It looks as if the cyl is staying where it is. cheers, JB
No problem with moving the copper cylinder to the attic provided the cold water storage (supply) cistern is raised into the roof's apex above the height of the cylinder. Alternatively you could fit a combination water storage cylinder which has its own cold-water header tank fitted on top of the hot water cylinder in an all-in-one unit.

You'll also may need to make a larger loft opening to get a pressurised hot water tank with all it's fittigs up there. The combi tanks with the header tank above the cylinder might work though.
An alternative if you need the space is do you have an underfloor area downstairs. There are some flattish box like cylinders from Germany which are only a couple of feet high and could be used.
Not particularly: just a matter of constructing a (suitably sturdy) platform at the right height. One sees this from time to time to give a better head for a shower without using a pump (usually on older installations when, presumably, pumps were more of a relatively expensive option).
Or a thermal store (more d-i-y friendly as doesn't require qualified installer to comply with building regs)
You can buy side on cylinders, that have a short height.

I have seen DHW cylinders with header tanks on top.
I have a mains pressure oe in teh loft.
But it is not a cheap upgrade.
Yes you can put them in the loft. However, you still need a cold tank above it. Alternatively, a mains pressure system, such as an unvented cylinder or heat bank could be used. These don't require a cold tank mounted above them, and would provide excellent showers even without the pumped power shower. You would need to check that your mains cold water supply is adequete, though.
If you go gravity, the gravity flow may actually improve, as the tank you had to raise would result in an increased head. Also, you can pipe between the tank and the cylinder in low resistance 28mm pipework, so the cylinder should keep up with the pump.
