Been using just pellets (and my Pre Fab fireplace/ although it didnt do much) for several yrs. Only had the 30-NC for last season. But my pellet consumption went from almost 4.5 (225 bags) ton the yr before, to a shade over 2 ton (110 bags). But I used almost 3 cord of wood (heating 2,180 upstairs and 800 sq of a 2,180 sq ft basement / 4,360 together, w/ all doors open).
I have enough wood on hand for 3 yrs now and enough pellets for 2-3 yrs..... I will not go back the the "Pro-Pain" until I am forced to... Whether it be physical limitations, age, etc.... Going from about $3,600 a yr to the few hundred now ($400 in pellets and whatever my time, gas, oil, equipment, etc is worth/ you know.. Free Wood
).
I love Wood and Wood Pellets. The pellets are more of a Primary. As they have T-stats and actually act like a furnace (one is a furnace) lighting themselves when heat is needed and going out when heat isnt needed. But I still Burn wood all day and night to reduce the consumption. Although an uninsulated basement isnt ideal. Im saving about 50% in pellets. And the basement is 90° for Mama when she does the laundry.
The Propane man hasnt came here in 3 yrs (this Nov). We are still around 40% from that fill 3 yrs ago (still cook with Pain).... Lookin forward to keepin him at bay.
