Your welcome, J5.
Since William first extolled the benefits of base heaters, there are now dozens of us with a Glenwood #6 and #8. And there are many of the Wings Best 116X and Harold #6 equivalent base heaters.
Anthracite is what they do best with. But we have a few owners that use wood in the warmer "shoulder months",.... and even a couple of owners that use Bit coal successfully. But shhhhhh,.. don't tell William !
In case you haven't seen William's six, wonderful You Tube videos of his #6 in action. https://www.youtube.com/watch?v=mWL5DuMWw4U
