Break Tank for Unvented Cylinder

[ln1234]

Can you recommend any makes/models of Break Tanks that can be used to store water and pump into an Unvented System (About 500 litres). Tank should have some sort of insulation as it will be placed in an area with no heating (but not open to elements). Is it possible to get tanks that keep the water 'wholesome'?

Thanks

what about http://www.polytank.co.uk/poltank454.html. That;s 100 gallons which is nearly enough. Or you could use sevaral and join them together.
