I'm currently looking at CB CL 6048, I will be heating a 1800 sqft house and a 30×40 shop. I heat with wood now, I have a buck insert ZC51 in.my house it does a good job as long as I'm home to fill it. I'm in a toss up should I keep what I got or go ahead and buy the CB while they still make them. The buck stove has a small fire box. I work 12 hrs so house is cold when I come home. I do have central air and heat pump. But I choose to burn wood due to high cost of electricity.
