We've got an old gas-fired system with a mix of large and small bore pipework, school and 'normal' type radiators and get reasonable heat from the rads. However, the towel rail in the bathroom remains stone cold. We've bled all the rads (none or very little air in any) but this has not resolved it. The towel rail itself does not seem to have a bleed valve. I've checked (I think) all the main 'flow' valves on pipes and rads and these are all open. Neither inlet or outlet pipe to the rail are hot. Pipes disappear into deep airing cupboard and then down under floor so not sure where they go from there.
Interestingly, the people who owned the house before us left us a bleed valve key with a note attached saying 'bleed system from highest point i.e. the towel rail in bathroom'..........Without a bleed valve on it how do I do that?!
Anway, any thoughts as to why only the towel rail remains cold?
