As far as the feed goes, I'm thinking about putting the pellet bag silo in one place and building a rectangular box with a pickup and hoses in another place. That way, to switch from bulk to bags, say if I run out and want to bag it, I'd just have to switch some hoses at the vacuum unit. I'm going to try to take the vacuum unit off today and put on the cover: we'll see how that goes.
In another note, I managed to take the scrunched up foam from underneath the Froling Energy Tank. It's about 2" thick. I tried putting a cut piece of foam back in, but there was no way, with the braces and limited access. I stuffed fiberglass in there instead. The Energy Tank has 4" of foam, like a sponge, around the whole unit (except the bottom), that is covered with a plastic jacket that is held together with a zipper. It makes it easy to mount external sensors on a rail that is bolted onto the tank. There is a plastic cap that goes over the top, but that was a little problem too, since I left it off when I put the valves, fittings, etc on top of the tank, and there are only two holes on top of the cover. I cut a slit in it and managed to get it over the fittings without cracking the cover (which I felt was miraculous since the boiler drain valve and elbow and Hyvent protruded quite a bit.
