Hello,
Can anyone offer any advice on following. Towel rail in bathroom not heating despite no previous problems - all other rads are fine. Relatively new pump installed on boiler system (conventional) which is on same level as bathroom (bungalow). One pipe to rail is warm but no heat getting through. The towel rail has been removed and flushed by a plumber but to no avail. Rail has been bled several times but apparantly no air lock. Any advice or tips on identifying cause greatly appreciated.
