I had a new Potterton Suprima installed in February 2004. It has
operated faultlessly ever since and I'm reluctant to have it serviced
using the principle "If it ain't broke don't fix it". The burner
flames look the same as when the boiler was new (blue with small red
flickers at the top). Bearing in mind that natural gas is extremely
clean, is there really any need for frequent routine maintenance? I'm
not bothered by the cost but concerned that careless maintence might
to more harm than good. Any comments?

I've serviced my own boiler and it hadn't been done in at least ten
years. There seemed to be nothing wrong with it and it appeared to
make no difference to the operation. My current boiler will only get
opened up if something goes wrong.

Indeed. Servicing suggests replacing certain parts routinely - like
filters - and cleaning where needed, adjustment etc. Once upon a time this
was a yearly job - cleaning the heat exchanger of the soot brought about
by burning town gas. But for the past 40 years or so we haven't used town
gas but the far cleaner burning natural variety.

So it comes down really to an inspection of the system rather than an
actual service or any maintenance. And in most cases the costs of an
annual inspection would be better put into a fund for repairs if the
system breaks down.
