I heat my home which is 1,500 square feet with a wood pellet stove and I use 1 40 lb bag of wood pellets in a 24 hour period.
A bag of wood pellets here costs around $5.00 to $6.00 which isn't too bad and cheaper than heating with propane.
So my heating cost depending on prices of wood heating pellets ranges from $150.00 to $180.00 per month which is much cheaper than what I was paying for propane per month.
