Unvented hot water tanks

[Craig]

Hi all - sorry, I know this isnt a DIY forum, but you are pretty handy with your hands so...

Can anybody recmmend a supplier of sealed hot water tanks that are slim - ie not just a regular cylinder? We want to install them in a ceiling void in the extension, horizontally. A rectangular one would be perfect.

Many thanks!

They're always cylindrical with domed ends because the metal is only under tension and can be much thinner. You probably could get a square one made, but the copper might be 1/2" thick!

If you can't find one you could get one made. Newark Copper Cylinders spring to mind for no reason, or Telford http://www.telford-group.com/.

Telford used to do a Tribune horizontal SS unvented cylinder, but it's not listed.

You'd need to allow access to service the P and T&P relief valves and the jooists will need to be adequate for the load.

Thansk Aidan. They were very helpful. They do do a horizontal tank, but only make them round. One idea seems to be to have multiple tanks, so reducing the size.
