hi guys we have the above fitted on our house which is a y plan system with hw cylinder.
The boiler works great the only issue is everytime the ch fires up we get a bass/humming/phone vibrating noise which happens 3 times in a sequence lasting approx 5 seconds, then once the boilers fired everything is normal sounding on high or low burn.
The noise can be heard throughout the house and sounds like a pump or fan self testing maybe.
I had the boiler serviced 3 months ago when we moved in the house. And just wondering if this is something i need to have looked.
Thanks guys and happy new year.
