Which Unvented Indirect Cylinder

[besenzig]

Hi

I am thinking of changing from a vented system to an unvented system with a Worcester Bosch boiler. Can anyone reccommend a good quality cylinder and should I opt for a pre plumbed one. I currently have two heating zones and one hot water zome.

I'm sure my plumber will have some suggestions, just wanted a second opinion.

Thank you

Go for stainless steel as lined or coated cheaper tanks fail and can be seriously damaged inside by rough handling during delivery!
