Outside wood boiler

Tom,
I intend to expand my wood burning from a Regency wood stove in my
cellar to an outside wood boiler. It's my intention to heat my home(3000
sq ft) with this boiler. I cut my wood on family property so, wood is
free. I would like to put in a boiler that's not going to smoke up the
neighbor hood. My neighbors are within 100' of me but, they are
seasonal. I do not intend to burn the summer months. Do you have a
recommendation on an outside boiler that will burn clean and
efficiently. My wood will be dry seasoned wood. My boiler will be kept
in a wood shed with a chimney 20' high. Any information would be a big
help. Thank you for your time.

Hi Bob,
Good question! Many of the original outdoor wood boilers tend to shutdown
and become rather smoky once the
system is up to temperature. One of the selling points of the outdoor
boiler is that they can hold a lot of wood. This
big capacity means that when they try to turndown once the house is up to
temperature, they get smoky.
A gasifier design might help, but a better solution might be to install a
storage tank in your basement to allow the
unit to fire out straight and dump all the heat into the tank for later use.

At any rate, check references of people who have used a unit for at least a
full year.
You can properly operate a unit without storage once you get a feel for
your home's heat load and how the boiler
works. There is a little bit of wood burning art here! And it will be a lot
easier to solve this problem in the dead of
winter!
