Short answer: switching to a gasification boiler can cut your wood use about in half.

One HeatMaster owner, "CountryBoyJohn" on YouTube, upgraded from a traditional HeatMaster MF10,000e to a HeatMaster gasification boiler. The MF Series is comparable to today's HeatMaster C Series.

With the new boiler, one stack of wood lasted him about a week at 15 to 30°F.
The same amount of wood lasted only about two days in his old boiler.
He figures he burns at least 50% less wood.

There's a little learning curve, but the time saved cutting wood is worth it for most people. See the G Series.
