What part of GA are you in? Have you identified a dependable source for coal? I ask because I'm originally from the Atlanta area and my Mom still lives in Blue Ridge - North GA. I spent quite a bit of time looking for a local coal source for her in the past and was unsuccessful. At that time, in order to make it financially feasible we would have had to order a truck load of coal at a minimum or drive north to pick it up ourselves. That issue maybe moot now since The Tractor Store is now offering coal at their stores. Maybe your local store would stock it if you asked.
We were looking for anthracite. Bit coal maybe available but it still would be a haul from the dealer to your stove. My suggestion would be to lock in the cost of coal, the type and source of coal that's available before you decide on a stove. You will need a stove designed to burn the type of coal which is available.
I'm not sure the Chubby can burn Bit. It will be very frustrating to try to burn bit in a stove not designed for it. The same as trying to burn coal in a stove designed to burn wood.
Another issue is the chimney. Many of the homes in GA are built with Class B chimneys that cannot stand up the heat of a coal fire. Those chimneys are meant for low heat wood fire, more for looks than heating up a house. With GA's typically warmer winters heavy duty chimneys just aren't needed. To burn coal you will need a Class A triple wall stainless steel chimney or a brick and mortar chimney? You will need to meet or exceed the stove's installation instructions and space setbacks to a T.
I would like to encourage you to use a coal burning stove to heat your house, but I want you to realize that you will face several obstacles to do so in GA. The biggest will be finding a dependable, cost efficient source of coal. With the cost of propane and natural gas today, you may find yourself spending more to heat your house with coal due to the cost of transportation.
I'm glad you found the forum early in your coal burning adventure. The folks here will be able to help you avoid the many pitfalls of getting up and burning. Don't hesitate to come back and ask any questions you may have. Lisa
