    BioWIN260 in combination with existing oil burner and DHW tank.

    3.5 ton wood pellet storage bin from Vermont Renewable Fuels Inc.: http://www.vermontrenewablefuels.com/bulk-storage.html

    The storage is not fully finished. The 4" lines to fill pellets from a pellet delivery truck need to be installed. Will post pictures later.

    Nice set up. How many sq ft are you heating? Good system for those who don't have time to find wood. 4 cords wood/year free; well, gas and oil for the chainsaw, truck, already own the land, and the biggy: TIME. But I like it, fun for me. I was concerned about moisture getting into the pellets and swelling. Any issue there? Best to you!

    Around 3,000 SF
    The BioWIN260 is 88,000 BTU/hr
    Should be just enough in 99% of the weather conditions up there.
    It's in a basement that has seen flooding in the past.
    That the reason of the metal pellet bin storage instead of a wooden pellet bin construction.

    It looks like the vent takes a pretty good jog before it goes up. Could you approximate how long a jog, and how high the chimney is?
    I'm (totally!) not sure you could do that with a wood boiler. Would seem to add flexibility in location.

    Do you get any sizable nugget build-ups? Any back up power for the fan in case of outages?

    The chimney is around 25' high,
    The horizontal section is around 6' long.
    During commissioning we recommended to change this to double wall chimney pipe or insulate this section to prevent condensation.
    Also the chimney itself is not insulated at this point in time what can lead to problems with condensation.

    The flue gas temps during commissioning where running between 185F at 60% modulation output and 215F at 100%.

    The reason it works is that the fan on the BioWIN pulls the combustion air trough the firebox and there is a little bit of a push of the flue gasses into the chimney system.
    This fan is not at all to be considered a power vent, but it helps to work in situations like this, although it's not optimal.
