Square hot water vessel?

[mjt]

Hi
Been asked to change an immersion on this cylinder (well it's not a cylinder as such as it's not cylindrical!!!) it's encased in insulation and a hardboard case!!!
It looks like some sort of combination unit as there is a warning pipe and cold feed on the top- anyone come across these before ?
Cheers

Looks like an old Elson tank, from Elsey and Gibbons.

Used to be common back in the eighties. A real earner when you come to scrap it.

There should be a label somewhere, and it will be the name of a gemstone - I think there was Diamond, Ruby, Emerald, Opal, Amethyst and a few others - all slightly different designs.

Thanks Ray appreciate the info.
It's all encased in this hardboard and tucked way high up the airing cupboard so couldn't see a label !!
Gonna have to drain it all to change the immersion which I presume is 11"
Oh joy

Just googled elson tank and it looks exactly like the one I've been to - thanks again Ray - you learn something new everyday and sometimes it's worth knowing!!!

Check around base for water marks on hardboard it's an older one by looks of it and they love to rot out . Also check the primary pipework / rocket inside as these can be a mess. Hope it's got a doc ! Or syphon it oot .

Yep it's got a doc but bet ya life the outlet is blocked with scale !!!
