I'm curious about what piece of European Technology you would like to see brought to the US boiler market?
Do you think is there a US manufacturer that could actually introduce these technologies and support them properly?

    Does it have to be

    European? One of the slickest things Ive seen lately is Navien tankless and that is from South Korea. I also think when fuel reaches the cost it is in Europe you will see a lot more innovation from all over the world.

    Not European

    but I'm really interested in MCHP hydronic units.

    I think these have a promising future here will far surpass geo/solar installs in 5+ years.

    I'll try to know a little more about them next week when I'm up in Utica.

    From what I've read the Freewatt system it uses a Honda motor which runs on natural gas. Be interesting to look at some real world figures and the bottom line. I always hear about how cheap they are to operate though I've wondered when you factor in the initial cost and then maintenance (the motor has to be rebuilt from time to time)what the real operating cost is.

    Freewatt

    Propane MCHP available also.

    The real elephant in the room IMO is what is the "real operating cost" to run a coal or NG plant supplying the grid .....

    One from long island

    Here is one I saw at the solar show. My bet is on water to water GEO powered by PV cells on a grid tie. http://www.geoenergyusa.com/

    More importantly is who will have money to pay for the latest technology?

    But internal combustion engines

    are only about 20% efficient. So 1 gallon of LP at 92,000 BTU/ gallon turns into 18,400 worth of shaft power? Then the friction loss of the generator. I'm not sure you can scrub enough thermal btu off the conversion to make it a very viable option. Even if it never did need to be overhauled.

    Freewatt

    claims
    Input of Honda MCHP at 18.5 MBH
    out of which - 12 MBH heat capacity is captured and 1.2 kW is generated. Total of 85+ effcient.
    The remaining btu's is generated by a mod/con.

    To me it seems like a very viable option over costly PV , definately far better than solar thermal for space heat (for my area), and the jury is still out on grid tied GSHP systems.

    I think the Freewatt module can also produce DHW. Hmmm

    Hope to see you next week.
