Hi,
Have been experiencing noise problems with gch system over past couple of weeks. New house. We have a volkera mynute boiler feeding 4 rads upstairs and 3 downstarirs. There is a wall mounted thermostat upstairs and another downstairs.
Whenever the boiler is on to heat the rads and the upstairs thermostat is set to anything above zero a loud vibration can be heard from one of 3 blue boxes fitted to the pipes leading to the hot water tank in the hotpress. The vibration stops as soon as the upstairs thermostat is turned to zero or the heating is turned off.
What exactly are the blue boxes on the pipes in the hotpress? Surely the extremely loud vibration is indicative of a fault? The noise is loud enough to wake you up if the timer is set to turn on the heating early in the morning.
Does anyone have any ideas?
Thanks
