Just out of interest I have just replaced my Gloworm boiler after 16 years service in favour of a combi. Just before I took it out I checked it over. The flame was nice and the inside of the combustion chamber exceptionally clean. In 16 years the boiler was serviced just once (end of first year - FOC!) and it's had one new thermo-couple. It has never let me down. Just proves that these annual services are sometimes a pure con and are not always necessary.
