We have a heated towel rail in the bathroom that runs off the central heating system. I am forever having to bleed it as for some reason the warm tubes get lower and lower in a matter of days. In this cold weather stripping off in the bathroom is not pleasant!
Should I be looking for an actual leak in the system? Is the system not powerful enough to run the towel rail properly? Anybody an idea of what I should do about this apart from wait till summer when it's no problem at all!
Thanks
