I have recently added a new radiator to a hairdressers I do some work in. They use the combi boiler for hot water in the salon and a hot water tank running on zone valves from the central heating to heat a tank for the staff kitchen. My problem is since the new rad was added the tank wont heat up. What do I need to check to get it working again? Is it a case of further bleeding? as all the rads heat up fine.
Thanks in advance.
