I have a Grant Vortex 36e, 36Kw keroscene combi boiler, used to heat the house hot water and radiators. I got it in 2008, so it's 8 yrs old now.

What does a service engineer do when he services such a boiler, and I can do this myself.

No are they expensive? What is he looking for and what does he change if they are out of range?

Hi Leakydave, I fixed a leak on the "prs-201 alco" system pressure switch this morning so I am fairly handy with it.
Why not look in the manual it's all there.

A flue gas analyser is about £700 and needs recalibrating annually. You'll also need a smoke pump, about £120, and the pressure gauge set is about £50

The above are used to check that the oil pump is working correctly, and that the boiler is burning correctly without producing excessive CO/CO2

Before this is done, the whole thing will be stripped, cleaned, checked for condition, nozzle replaced, supply hoses replaced, filters/gauzes checked and replaced as required, seals sealing correctly and that sort of thing

Can you do it yourself? No, not really.

If it's not been serviced for eight years it's likely to cost you more than a standard service as your service engineer is going to have a tough time cleaning it properly. You'd better hope that the lack of regular maintenance hasn't caused damage to the baffles as well, because if it has things are going to get very expensive
