I had an Ideal Response combi boiler installed 3 years ago. I am very
pleased with it, and after two years the manufacturer gave it a service
under the terms of the warranty. A year later I rang my local engineer
to book a service. I had used him for years on my old boiler. He told me
not to waste my money on an annual service, as combis didn't require
cleaning out like my old Potterton. If it was working satisfactorily, I
should leave well alone and only call him if there was a problem.
Is he right, or should I find someone who will do it? I have never had
reason to doubt him before.
