2 Stage Residential Oil Burner ?

I had heard Carlin and others were  working on a 2 stage or a modulating oil burner suitable for smaller residential boilers. Anyone heard where this stands at the moment?  Is there any chance of a residential 2 stage steam boiler coming in the near future?

    The Last I heard

    The last I heard the Carlin burner was certified with a few boilers but had to be direct vent, the reason stack temps are too low for a chimney.

    Leo- Thanks for the reply. I can see where there might be a problem with low stack temperatures. As oil prices are bound to go up again, I'm hoping for  a way to make oil fired steam heating more economical. 

    While it might be a small volume market, I would have thought that one of the boiler manufacturers would have pushed this more. I think you could control the residential market if you had  a high efficient steam boiler with a 2 stage oil burner.

    I think it was Boiler Pro who was working on something like this last winter  I wonder how that worked out?

    It all depends

    on how far you turn down.



    Typically on a steam system you're just shedding the pickup factor once the system is warm. If the boiler is not grossly oversized, the stack temp would probably be OK. Of course you would have to verify this with a digital combustion analyzer.
