I have a myson apollo fanfare boiler. There are 2 strange noises that concern me...
1. When the CH and HW is off the boiler seems to come alive every 4 minutes. It is not firing up like when the CH or HW comes on but rumbles away for about 30 seconds and then turns off but then comes on again every 4 minutes. Could this be anything to do with the pump?
2. The latest noise sounds like water dribbling into the HW tank - its very loud and its only just started doing it. Could this be air trapped in the system?
Any advice appreciated! Cheers
