It burns longer, too. Case in point: A small town close to here in Pa. called Centralia, has "anthracite" under ground veins burning that weave under the town. Since May of 1962! The government bought the town and made everybody move out, except for a few old-timers that won't budge. They're still burning strong and every once in a while, smoke bursts come up throught the ground to the surface. Wouldn't that be an exciting place to live !!! :?Kodiak":104rwy3h said:The Anthrocite coal that Carl mentioned is the best for heating as it packs more BTU's.
I have a 7"x12" flue chiminy. The gas hot water heater and furnance use it too.
