Hope someone can help with the following... I had an issue with No Hot Water and after going to the boiler I noticed the Pressure was going all over the place 0.5, 0.8, 1.2, just cycling through different pressures and the fan was making a whirring noise. I turned everything off and removed the...

(Part of) my central heating is controlled by the wireless thermostat Honeywell HCW80 and the relay unit HC60NG which triggers the zone valve actuator. The two are linked (i have followed the instructions after resetting both to try to solve the problem and all is well). When i turn the...
