I’m not trying to criticize but I just did a fuel cost comparison on coalpail.com and it looks like heating with wood pellets is more expensive than natural gas or propane and several time higher than geothermal. Even if your getting pellets for $200 a ton.
Funny you mention that...
We buy some pellets every year, and fuel oil every year. We filled all 3 oil tanks up early this Spring when everyone was Covid Crazy @ $1.79/gallon. Just this morning I ran the numbers - for us, this year, it's a 100% wash between oil and pellets as to which cost more or less to burn.
The benefit of the stove is for mornings like today - send the stove through 1 or 2 cycles and it's good for the day. The stove is off before the baseboards would start getting warm. We live in NNY, there is a reason we have more than 1 heat source.
Having said that, from 1992 to 1997 pellets were are primary heat source, with electric baseboard as the secondary. When the addition went on in 1997 a boiler went in. When we built the garage in 2001 an oil boiler went in that too and has worked well. It's insulated well too so it's pretty cheap to heat.
If we had natural gas available I'm pretty sure thats all we'd use, but we don't. I'm also not a big fan of a submarine tank in the yard holding enough propane either.
