The boiler is from an old hotel. It was part of their hot water system. Think of a 55 gallon barrel, then make it about a 150 gallon barrel. That's basically what it looks like. Those things have been out of date for many years now. Grandpa was a great scrounger and got the thing for free. Cut in half, we ended up with two watering tanks for the cows. I think a lot of people use livestock tanks for water features. You can get them at any farm supply store and I'm sure there are plenty of those in Colorado.

This picture may show it a bit better. Please bear in mind I have no idea what I'm doing with this thing but I won't let that stop me.
