Over the last couple of months i have started to notice when my central heating system switches off i sometimes get a couple of loud thumps come though my sub-woofer.
My heating system is a normal boiler (Worcester 15Ri) coupled with an unvented hot water cylinder. Both hot water and heating are pumped around with a Grundfos Alpha2L pump.
Really struggling to try and find a cure to the rumble that affects the sub-woofer? Any suggestions would be most grateful.
