Twin coil unvented cylinder + solar collectors?

[Mike2007]

Does anybody know a good internet based stockist for a 300litre unvented + a couple of water panels?
I have had a quick look on ebay for cheapest retailers, but wanted the crack from you guys before diving into buying all my kit.
Sometimes having a "trade account" at a local merchant can still be more expensive than buying "full price" over the internet! :/

Cheers

Best to use a vented thermals store in case of overheating. Try Navitron for starters
