A fireplace insert with fan is basic for getting some decent heating
performance.
Top Drawer: I have a large fireplace w/doors in the livingroom. It has
an integral fan forced heat exchanger that blows out the bottom of the
unit. The thermostatically controlled fan unit is mounted outside on the
side of the house. The exchanger is also ducted into the house's
fan-forced natural gas heating duct system. A shift of the duct lever,
and the fireplace heats the whole house.

Considering the projected high cost of heating this winter and to
supply an alternate heat source in case of fuel/electricity loss, I am
considering installing supplemental heating fueled by wood.

Since in the past this group has been a fountain of good information, I
thought I would ask for your advice.

I would like to hear of your experiences, recommendations for suppliers
and suggestions for installation.

Thanks in advance,

TMT

I don't know about the present models, but 20 years ago a good stove

only about 65% efficient...

"Efficiency" is a matter of how long you can keep the warmed air in the
space to be heated.

You are talking about something different. We might say that a heater's
efficiency is the ratio of the amount of heat released to the house to
the total amount of heat released when the fuel is completely burned and
the combustion products are cooled to room temperature.

"Combustion efficiency: (actual heat produced by combustion) divided by
(total heat potential of the fuel consumed)"

This is a very good resource about bioenergy.

I still read Ed as talking about stove efficiency, which is how much of
what's produced by burning is recovered to heat the space rather than the
chimney. Nick's definition.

Combustion efficiency suffers on oil burners as well, do to incomplete
atomization and combustion.
