That is why he is asking,alot of wasted heat.
I know the top loaders are diffeant. On my Heatmor the smokes goes up in the front,into a 4x6 inch piece of rectangle tubing,goes the full lenth of the OWB and than goes out the pipe.

Thank you for all the suggestions. I think the dart fan controller will probably be the best long term solution. It will allow me to easily run the fan off/on or anywhere in between. This boiler isn't designed for efficiency. It is made for ease of loading with a machine, long burn times and big heat loads. In a perfect world I'd feed it nothing but 5ft long 20in diameter green red oak logs. 20f outside and heating my house , kiln, barn and domestic hot water I can easily get two days between loads. On days where I have more time to mess with it I'd like to start working through my mountain of mill scraps. I'm hoping to get 24 hours of burn time with scraps or better. I really think if I can slow the flow of air by switching the fan off I can achieve that.

Which ever way you go you will definitely see a reduction in wood usage once you get things dialed in. Good luck with it.

You will find that in the long haul the money spent on the Dart controller will be well spent.
