    The boiler was new 2014, we moved into it in 2015 with no paperwork for anything and we started hearing gurgling/ knocking noises after hot water was drawn off for up to 45 minutes afterwards. We have had the following work carried out:-
    • New heat store thermostat
    • New circuit board
    • New hot water pump
    • Power flushed the heat store
    • Modified auto air vent supplied from Firebird as a possible solution
    • Smaller oil nozzle down to 0.75 from 0.85
    • The above has cost us £650
    • Mag filter fitted to inlet as a measure to clean system
    Still no improvement whatsoever and Firebird have washed their hands of us as the boiler is out of warranty, although only 4 years old the only solution we can think of is total replacement for a more reputable brand.
    Any suggestions or similar stories gratefully received, I've contacted the WHICH.co.uk legal team and we are discussing possible options.

    I would advise you replace it with a non combi oil boiler (system or standard boiler) and an unvented hot cylinder, if possible. Grant Vortex my preference.
    Pity you have already spent £650

    Need to get hold of somebody who knows what they are doing. Nothing much wrong with a Firebird, but somebody's had your eyes out.
