Mains pressure cylinders.

[Ian]

Are there any really small diameter tanks? I've go 470mm to play with (including pipework.)

Hi,

What sort of capacity and heating method are you looking for? Albion have marine calorifiers that are good for 3 bar and tested to 5 bar.

cheers, Pete.

DPS do a 480mm heat bank. Are you sure you have only 470mm?

You may find greater difficulty finding a small unvented cylinder than a heat bank. Unvented cylinders have greater regulatory burdens associated, so there is usually less in the way of choice as every design and size has to be expensively type approved.

See thread "Pandora too wide" above. Elson claim to be able to manufacture one off designs to individual specifications. Also, rectangular shapes are available, so a narrow, but deep space might be usefully employed. You'll need to speak to them directly to see if a suitable size might be manufactured.
