I'm located in West Michigan and use a 2006 Central Boiler 6048. My house is approximately 1400 sq ft with a full basement. I do not heat dw as I have natural gas service and there is a minimum charge so I may as well use it while paying for service. I have approximately 5 acres but live in a village. I use approximately 8 full cords for heat. I'm extremely pleased with the CB and would recommend it to anyone that lives in a rural setting but I am going to "up-grade" to an EKO gasifier within the next two years as there is talk in town about outdoor boiler ban in the village. I'm extremely careful to burn dry good wood and I'm not having an issue with the smoke output, but I'm sure at somepoint someone else will put an OWB in and not take care of how they will burn it. I only fill it once a day, and always at night. It really irritates me that OWB are getting such a bad rap, but it's the owners that are screwing it up for everybody. I was talking to someone the other day and they were bragging about only having to fill there OWB everyother day. They stated that they fill it as full as they can with green wood and it would hold a fire that long. I asked how much smoke he was producing and he laughed and said that sometimes he couldn't even see the woods through the smoke. I suppose we have to pass Laws to protect the stupid.
