A 40 lb bag of wood heating pellets will usually give you 24 hours of heat and burn time depending on how large of a wood pellet heater you're using.
It usually takes around 100 to 150 lbs of wood pellets to heat a home for the winter depending on how big or small your home is and how cold of a winter your location has.
So it costs around $200.00 to $300.00 per month to heat your home with wood pellets.
