Hi All,
I have the above mentioned boiler linked to a Nest Thermostat. The problem I have is when the boiler is set to No.5 which heats the water to circa 67 degrees, it reaches temperature, the gas light goes out and it cools down to circa 30 degrees then heats back up again. This continues for the whole time that the the Nest is calling for heat. The issue is the house struggles to get to temperature.
If I set the boiler to between 6 and maximum (heating the water to circa 79 degrees) the boiler stays on constantly until the Nest Thermostat reaches the desired temperature.
I've spoken to Worcester and Nest but neither can understand why the boiler would be doing this.Ideally I want to run the boiler on the lower temperature which is sufficient to heat the house and water.
The boiler is approx 8 years old and has recently been serviced which did not identify any problems. The engineer did suggest there could be air in the system which I've checked and all seems fine.
Approx 2 years ago when we were having some work done, the builders drained the heating system which unfortunately meant that significant debris from the F&E tank got sucked down into the system amd meant the water could not flow from the boiler and it was cutting out. We had an an engineer at the time reverse flush the system and the boiler came on but could this have caused the problem? Could there be damage to the heat exchanger? This all happened when we had recently moved into the house in the summer time so I'm unsure how the boiler was functioning before.
Any suggestions would be gratefully received.
