Highly compressed softwood pellets are great - better to use it, than lose it.
I heat my whole house with them from Dec 1 to about Mar 1
Do you have any chimney issues ?
The hardwood pellets throw out much more heat and are the same price. We’re using Walmart hardwood (U.S. made) at $224 per ton, Tractor Supply was $239 for “sawdust pellets” which turned out to be from Canada and were made from Pine sawdust. Not much heat from them. Hopefully this winter will be nice to us upstate NYers!
