I have a Potterton Kingfisher CF50A boiler which is older that the 23 years we have lived in the house, and which has been serviced annually by a gas-safety registered engineer and has worked very reliably all that time. This year I had to ask a different registered gas man to do the service, which he declined to do, instead telling me that I need a new boiler. He pointed to a white powder which has appeared down the edges of the heat exchanger gaskets, said that this will lead to leaks, and that a repair is no longer feasible due to the boiler's age.
Does this seem reasonable, or am I being persuaded to spend a small fortune unnecessarily?
