I would like to install a square folding tank in my crawl space. I have about five feet of height, has anyone done this and is it possibe, is it a good idea to put one in a crawl space? This is the one way I can install one right now, I just don't have the room in my garage. I already have a Solo 40 in my garage. I got a rough quote of $4500 for all the parts and probably $500 for shipping to Alaska. Is there any members up here in Fairbanks with a square tank setup I can take a look at? Thanks Doug
 
My tank is 54 inches to the top of the cover. 49 inches top of tank w/out cover. The Hx's must be 18 inches in diameter? You'd have to put 2 layers together, put liner in, lay HX's in liner, slide top section, pull liner in place? Dunno? I would think you're going to have to have enough room to crawl into tank, just to get liner properly placed. One thing, and check with manufacturer, use pop rivets instead of the screws provided. The sections will slide easier.

What kind of floor do you have to set this on? Do you have a lot of room all around where you want to put it?
 
I plan on setting it on top of a platform made out of treated 4x4 and treated plywood. I may have to dig some material up to get proper clearance. I am curious if it will get humid or does the lid seal it pretty good. It stays around 50F all year down there. Thanks Doug
 
You can install on a PT deck, but need to have something separating the tank from the wood (6 mil poly is fine). The biggest issue is getting over the tank to screw the top down.
The tank will seal tight, but you do need to be able to get a cordless drill overhead and drive the long screws through the cover.

Phil explained the way to assemble very well.
I am always concerned if someone has to get into a tank for any reason, access is usually not necessary, but when it is, if the quarters are tight,
life sucks.

Humidity is not a big issue. The tank does have to be on a dry surface.

I've got two 500 gallon propane tanks in a 4' crawlspace that are working well. They would surely be less than $5k but would take a decent sized opening (~36") and some user modification to make work.
 
I'm near Denali. Love the setup...folks here provided a huge amount of information for planning and design. 'Bout time I posted with before, during and after pictures and results.

For a 2,400 sq ft 5 star plus (VERY well insulated) home the following is how my system is working. Currently my tanks are barely insulated while I fine tune some additional plumbing. I expect better results when I blow in cellulose around the tanks.

I burn 6 cu ft of dry white birch per day between 5-20* F.

Between -15 and 5 I burn ~9 cu ft.

Warmer than 20 and I'm burning 6 cu ft every day and a half or more.

Over the summer I'd burn 6 cu ft every 4-7 days.

This is my first heating season so more results coming as the temps drop.

I'm thrilled with the setup. It is very easy and fun to use. Now I'm studying up about 1-wire temp sensors, data logging and advanced controls. But I probably should just enjoy what I have!
