I'm trying to determine the pros and cons of having a wood boiler

Anyway, I'm looking at a Heatmor boiler, and I'm now looking for
people who have experience with these. *The website says that the
boiler has a forced draft fan (75 cfm). *It also says that the boiler
can heat a 3000 square foot house. *I know a little about combustion,
and I calculated that with 75 cfm, you cannot burn more than 10 lbs of
wood an hour. *And if the wood is 45% moisture, then the available BTU
is around 40,000 BTU. *A 40,000 BTU furnace is very small for a 3000

So, has anybody dealt with these Heatmor furnces? *Can you tell me
anything about performance and maintenance?

If boiler is outside full of water , you must put antifreeze in the
water, antifreeze doesnt transfer heat as well as water, is that
included in their btu output calculation. Do you have to feed it every
hour that would become a hard full time job
