Fitted about 18 months ago there seems to be a bang or thud when it turns on and off is this the gas valve ?? will a new one be any better. The fan seems to be loud as well, will a new one be any better ?? turning the temp up or down on the boiler makes no difference.

if the boiler was fitted 18 months ago you should have a warranty that covers the boiler contact glowworm direct for assistance
