    How do you guys insulate the supply and return lines of a closed loop system when the lines must come above ground to enter into the building?
    This is a NJ job where weather of extreme heat and freezing could be an issue.

    Depends

    On how above ground they need to be and the distance of the run.

    A concrete box full of insulation for example. Some foreshore work has involved some fancy concrete work to blend it in to the rocky coastline.

    We do a lot of this and typically the general gets the carpenter to frame it out and the insulator fills it with closed cell or other expanding insulation from the penetration to below the frost line. YMMV

    Not in my world. Wasting bales of wheat straw means that someone is not getting their adult bevrage...:eek: just saying?

    DUH

    The straw is what is left over after they make the beer.

    Here the spent mash is feed to dairy cows so all the kids in Ohio have one foot on the bar rail when they eat their free lunch. No wonder we have issues with substance abuse.

    This is all just a difference in local codes, no doubt.

    Your right Mark, local codes are the differance. Here we re-pitch the yeast add some sugar and make high test.

    Wheat straw remnants

    For those of us who may be "dirt poor" the term came from when you could only afford a dirt floor. When you would thresh the wheat, after removing the grains, you could cover your dirt floor with the remnants. So as not to lose it to the outside, someone came up with the idea of a threshold.

    You do realise we are talking about untaxed adult beverage production, and not insulation?:D

    Thanks for all the help about the lines guys. This bread has helped me clear things quickly.
    On the brighter side of things , I've learned a few new uses for bales of hay.
