Heat Storage - Water Tank - Setup for domestic HW and space heating

[TarmMBSolo55]

If you had to "just buy one" what would you buy and where? I know that Tarm sells a setup that you can squeak in through a basement hatch, but I have a 80" high x 8 foot wide door I can bring one in through to my cellar. I live in Western, Mass.
I am heating 1,900 sq ft of cellar slab, 2,300 sq ft of baseboard high ceiling house, and eventually a 900 sq ft garage slab.
Thanks

Because of the transportation costs, storage tanks are not a commodity item. If I had to start from scratch, I'd look to see what my friendly local scrapyards and farmers had. A stainless milk bulk tank is good. I'd also see if I could find a pair of 500 gallon propane tanks. While we don't have the 20 year experience with using propane tanks as pressurized storage, my gut says that's a good way to go. Bottom line is that the best deal is likely a used tank that's nearby.

One of the reasons I like the two 500 gallon propane approach is that it would allow you to achieve a greater degree of stratification. That's extremely important in my application.
