Well I cant say enough about coal. Never got above 22 deg during the day yesterday, and got down to -5 deg last night and woke up this morning to a house that was a toasty 75 degrees! And the best part about it was from 6am the previous day to 6am this morning i burned only a little more than 1/2 a bag of coal. For years I struggled with a pellet stove burning 2 bags a day when it was cold like this only to wake up to a cold house. I really dont know why more people arent aware of the ease, cleanliness and warmth of coal. Coal Rules!!
