I have an ideal isar he24 condensing combi boiler with a heating fault.
the hot water is fine- no problems. but when the heating is due to come on the 'c' appears in the window but the light just flashes, you can hear and feel the valve open and release the hot water that the domestic water as heated into the central heating line. There are no fault codes and the water pressure is set to 1 bar as stated in the book, and the room thermostat is working fine. Any suggestions.
