I've got a 125,000 btu rated boiler that's over twenty years old and the OEM is out of business.

Anybody have an idea how one could get an estimate on it's efficiency? I'm reasonably sure it's nowhere near 80%. But it works and was cheap.

Thanks!

As for the "chopper axe", I'd have to borrow one before I plunked down 70 bucks for it.

Back in the 1970s or 80s, when the "Chopper" axe was being marketed heavily, I worked in a hardware store that stocked and sold them. No one that split much wood liked them. They would jam, parts would break, etc. A regular maul works well, and the Monster maul with the pipe handle works okay for stuff that might be too hard to split otherwise.

Here's a new Oil Drum article about wood as an energy source in America. As already pointed out, wood has limited potential as a thermal energy source, but its role shouldn't be neglected, especially in the more densely forested regions. There's also some interesting discussion about wood stove efficiency.
