has anyone had excessive noise from these simple little boilers.
noise when on heating i think the heat exchanger is partily blocked,its only 3 years old,max.
sentinal x200 was added 4 weeks ago but now even more noise.
boiler stat is set very low,has correct gas burner pressure,no blockages in visable boiler water parts and a new (complete)pump fitted 4 weeks ago.
hot water there is some slight banging noise but its acceptable.
thanks.
