Hello
Just a query really. I work on oil boilers/Rayburns and use an analyser on a daily basis.
I worked on a relatively old Trianco Eurostar earlier which hadnt been serviced in years. Did all the usual, replaced nozzle (with a 'W' as didnt have the correct 'S'), checked oil pressure and set Co2 to 12.5% as advised by the literature. When I printed off the readouts I noticed that the efficiency was 91% ?? How can this be possible on an old, non condensing boiler ? Are these efficiency readings reliable in the slightest ? oh I had a flue temperature of around 220 degrees also so I just cant see how that would be possible ?
Analyser calibrated around a two months ago
Many thanks
