    Recommendation on a new burner?

    I have a WM gold SGO7 oil steam boiler that is about 8 years old with a becket burner. Can anyone recommend a replacement burner which might be a more efficient all around? Thanks in advance everybody.

    Not really

    The one you have now is a good one. You could ask your service technician if it needs improvements
    (ie; oil delay valve, better primary control). More important is proper set-up and testing of burner.
    With that said next would be proper boiler piping, insulation, and venting too really save money on operating costs

    I agree

    remember, once the SGO has generated the steam, its job is done. From that point, the system must move the heat to the radiators. Look there for ways to improve your overall system efficiency.

    Are you having soot problems or hard starts?

    Make sure... (corrected)

    the servicing technician leaves a record of what his test instruments read after he made the burner combustion adjustments.

    If it takes between 20 minutes and a half hour for a dead-cold start for steam to make it to a few rads, the nozzle size selection is excellent. If it takes more than 30 minutes, the nozzle may be too small, wasting fuel. If under 20, the nozzle is too big - also wasting fuel. Either will cost you an added 10% at least.

    The boiler should get at least 84% steady-state combustion efficiency with instruments. If it doesn't, it is either dirty inside, or the burner not setup properly. Either way, you lose yet again.

    A day/night stat could save another 10%. Just don't buy one of those gypsy-good-time units from Homey.

    Let us know what you learn and how it works out.

    If

    your current burner has a PSC motor,electronic igniter and interrupted ignition you will not gain anything by retrofitting a new burner.If you don't have these features I would consider a new burner.Electrical consumption is much less and the boiler will stay cleaner increasing the efficiency.

    And don't forget

    valve-on and motor-off delay, which really clean up the starts and stops.

    As of 2005, Beckett AFG burners built to SGO spec had all the features Robert and I mentioned.

    a new burner is not always necessary. You can upgrade the controls to any Beckett burner. A new Beckett primary control is coming out in the fall which looks really good. I can't wait until it is available.

    My current primary is a R7184B1032 would it be beneficial to go to a R7184P1072? 3lees what exactly will be the upgrade to the one due out in the Fall? Thanks

    I would have a pro make that change

    the R7184 P or U controls also feature motor-off delay for cleaner shutdowns.

    Does the burner have a CleanCut fuel unit (oil pump)? If not, I'd have that installed too. It has the solenoid oil valve built-in that is operated by the R7184 B, P or U controls. This unit is now also standard on current Beckett burners sold with SGO boilers.
