Pete69, I talked to Larry Trainer, the designer of the Coal Chubby Stove, and this is his statement regarding using Bituminous coal in a Coal Chubby.
"The Chubby is designed for anthracite and bit is probably not a good choice for bit until the day we make some modifications to it to make it support burning bit, which could happen someday. The Chubby was never tested with bit. Because there is such a large variation in the volatility and types of bit I can’t make a blanket statement on burning it."
Here is the link to Larry's Coal Chubby website. http://www.google.com/url?url=http://ch ... OdeJxl192g
Notice in about the sixth paragraph down, it says "Our Chubby Stoves do not burn bituminous coal, the coal used in power plants to make electricity. The Coal Stove Chubby burns clean hard soot less American Anthracite coal used for residential home heating. Anthracite is cleaner than wood, will not cause chimney fires, is ok to burn if wet, and will give you twice the heat per pound as wood. A Chubby Stove is not like your grandparents old central coal heating system. Consider an American made anthracite parlor stove. Supplemental heating with anthracite costs about $325.00 per year."
Boy, I have to tell you that Larry's customer service department is number one. I emailed him this question after I read your question, Pete69, and when I checked my email this morning, I already had an answer. WOW!!!
Maybe more of us NEPA members should start emailing Larry to get him in the manufactures part of the forum.
Just an idea?
Thanks for the fast reply Larry!
