I had a Ferroli F30 boiler installed 18 months ago, which is great and i've had no probs at all with, but am unsure about draining the system, as i want to fit a heated towel rail into my bathroom. I have done all my own plumbing apart from installing the boiler, as i did 18 months as a youngster at college for plumbing. I knew how to drain my last system, but don't know where to start with this one. Please can anyone help. Failing that i guess i'll have to see a man about a boiler
