Hopefully the final question...! I believe the problem valve to be one usually turned with an un-marked top (as opposed to the other side, which clearly has a + mark on it...). Underneath the top is a short cylindrical spindle, and then a small grubscrew, with room for the spindle to pass...

Of course, looking at a typical system diagram, it occurs to me that if I'm draining the return side of the system, it doesn't matter what position the y valve is in.... what a learning experience this is! :)

Thanks for the help so far... will have a crack at the open valve with a bigger and better pair of pliers.... :-) One question remains - I am draining the rad, and also it seems, the rest of the system, including the expansion tank. Surely however, I should only be affecting the 'rad' side...

Came home to find a 'burst' radiator (water spewing from a very small, but nevertheless annoying, hole). Have checked the system as best as possible - appears to be 'y type' or similar, so have set the boiler to provide hot water only and no heat, as it doesn't seem possible to turn off both...
