Thanks All I think the ely one is more for a domestic hot water system but thanks for the input Alan!! I remember seeing a really simple one somewhere that had a hose connection on the bottom and an overflow connection at the top same as most Heat Exchangers, i just cant remember where I have seen it!! Beta Marine do something similar which is listed on there website but can I find a supplier? I was going to try Ludham Bridge Boatyard but Jasons website seems to be down for some reason so cant email him!

Ouch!!! Thanks for that option but cheaper and plastic would be better!!! The reason im saying plastic is because you can see the level without having to open it. Thanks

I am looking for a simple plastic coolant expansion bottle for my boat that has a radiator cap type fitting for the lid, there are many on ebay from cars but nothing that looks like it would be easy to mount to a bulkhead. Could any members suggest where I might be able to find a more marine orientated one, I have tried all the usual norfolk based suppliers websites to no avail! I only want to fit so I can monitor the coolant level without having to look into the Heat Exchanger and also give the system some expansion space. Many Thanks
