i've had a 25-pdvc for 4 years now, and decided to upgrade to a multi-fuel. this baby is a totally different animal than my old stove. i noticed an air blower box which i'm unfamiliar with and a chain and sprocket to run a stirrer with. seems a little more mechanical than my old stove. also another control module. i went with another englander because of the great luck i've had with my previous stove. hopefully this one will perform as good as the last. the model is a 49-SHCPML. i bought the unit at lowe's and they matched am fm's prices so it was a good deal. i guess with anything new i'm a little apprehensive. i will be installing this baby in the spring and should have some pics then. regards.
