    Yeah. They are staying there forever. Tanks are 13' and bottom of truss is 12.5' so we had to line things up just right. Spray foam insulate. Them and the trench and the boiler room in barn.

    Oh I remember. Mine barely fit. Had to lift them a half after I had them stood up, just so I could thread on fittings.

    That looks great. When the weather breaks I'll have to take a ride down and check it out in person.

    Do you know what brand or method of foam you will use? I use a DIY product called Foam-it-Green....it works great but is very pricey!

    That is comparable to the price of the DIY kits I always have a place to to put any extra...The closed cell foam is the best way to insulate the tanks though.

    The foam is not cheap but very effective...The kits that I buy are 602 bd/ft for $680.00 shipped. That includes a $50 discount since I have bought from them before. If you decide to go this route I can get you the coupon code.

    No problem... when I figured the amount I did not consider that the foam on the tanks was 4" thick...that makes a big difference.

    CR, what did you do to prepare or purge the tank for welding? Nice job BTW.

    Ahhh.... Once you cut that big hole it was easy to get inside to pressure wash or vacuum. I presume you blew fresh air in before you hit it with the hole saw or is that 2" hole from a torch. I've heard of the propane like being absorbed in the metal or something but don't know how dangerous that can be to my welder. The link to your post is helpful. Thx

    i did not blow air in before hole saw (i wish i could cut that good with a torch!) in my limited research on leftover propane gas in the tank, its seemed the only repercussion was a flame out of the other holes for a few seconds so i did not invest much time preventing that. no problems, no flame. it wont explode if not contained. i was not worried much after discovered holes in the bottom. with all the scale in the tanks i imagine it had more than adequate time to vent out.

    Foam insulation is pricey, but very effective. Closed cell is the best. Another alternative is to build a box out of rigid foam. I used double layer of 3" thick ureathane roof deck insulation gapped an screwed with self tapping screws with plastic washers to metal studding. Before using rigid foam I wrapped the propane tanks with fiberglass insulation, then rigid foam panels then spray can foam the cracks. I don't know how it fares to srayed foam. I do know my heat standby loss with no load is about 20 degrees in 24 hours. Is this excessive?

    Does seem excessive. You have 1000 gallons, right? That would be 8,330 btus per degree x 20 degrees=166,600 btus over 24 hours or 6,942 btus/hr.

    i hope i dont see that much, especially since the barn where the foamed tanks will be is uninsulated and its cold to begin with in there. i am doing spray foam because the guy will be here for the trench anyway. i hope 4" is adequate but if it is not i will box them in with foam board.
