    Kickstart THIS!

    I'm curious to hear what other ideas people would consider supporting via crowd funding. Smart vents that ensure balance? Variable EDR radiator valves? ???

    What's missing from modern steam?

    How about

    an affordable outdoor reset control for single-family residential steam?

    It's coming. Anyone interested?

    The alternatives

    are quite expensive?

    Quite

    The outdoor reset controls currently available for steam are targeted towards commercial and multi-family buildings rather than the residential market. They're a bit pricey for the individual homeowner.

    In principle, there's no reason that outdoor reset shouldn't work on smaller systems. And in practice, the outdoor reset control on my residential system has been operating successfully for a couple of years now (even before the Midco burner).

    I'm ready

    Also, could your control system be adapted to a hot water boiler, for a wider audience?--NBC

    Hot Water

    It could, but there's a much wider selection of ODR systems out there for hot water, so it's probably not worthwhile to try to compete in that market space.

    Knowledge, of course! that's why we come here.

    actually, I believe steam has plateued because the market is shrinking. A 90%+ efficient boiler maybe?
  • ChrisJ ChrisJ @ 10:47 PM

    Fix that

    How can you make the market grow?
    How can you make a steam system that will compete with other cheaper systems?

    You would think a system with almost no moving parts, no pumps, no fans, could be made to be cheaper then forced hot air, some how.

    I'm all for an outdoor reset for systems like mine.

    well that microsteam system certainly sounds intriguing

    I dont know how I missed that thread.

    Mark, I think we have a great candidate in ChrisJ for a launch prototype! He lives a few towns over from me, so callbacks won't be brutal.

    Absolutely

    I'd be glad to be a test subject if the opportunity ever presents it self.

    That's great, ChrisJ, thanks. I'll put you on the list of potential beta testers.

    a code approved

    millivolt gas valve would be nice..steam boilers could be rated at higher efficiency i would think if they also used no electricity.

    The return of the

    Hoffman #10 main vent would also be nice..the only thing venting faster than that was an open 1/2'' pipe.

    3/4 inch mains

    I'm looking back through the SelectTemp brochures. The technology seems so relevant to today. Is there a design/install manual out there somewhere?

    Things I'd Like to See With Steam

    1) Hi-Lo firing in all size models.
    2) Accurate low pressure transducers in place of pressuretrols or even Vaporstats with direct digital read-outs of actual system pressures.
    3) A high temperature sensor in the flue gas stream to shut down boiler to prevent dry-firing in the event of LWCO failure.
    4) Sightglasses with ALL brass components and proper blow-down valves.
    5) A main vent with twice the venting as a Gorton #2.
    6) An affordable single pipe steam TRV.
    7) 3 small tube cast iron radiators made in the USA.
    8) Affordable firing cycle/outdoor reset t-stat (as others have said above)
    9) Add an O2 sensor in the flue gas stream, combine with the temperature sensor above add a processor (from an I-phone app) and get real time combustion efficiency...

    *sigh*
    Dream on, I guess.
