Building a water tank

[vpd66]

I have heard on hearth.com of people using old propane tanks. They usually purchase the 500 gallon ones and put two or three together. There is a lot of information on that site about boilers and adding storage.

I admit I did not read all the treads, so if this has been suggested before sorry.

Yes , I know about hearth.com, its where I got the idea. I'd use old propane tanks, but they don't fit in the shed I want to put it in. Thats is why I'm wanting to build my own tank to fit the space I have.
