Found this on Travis Industries site http://18.104.22.168/CostOfHeating_WkSht.asp?P=2 Try punching in some numbers. It's just not realistic. I came up with $20 to heat my home with electricity per month. HA! That's a good one! It's off by about $300-400. If it only cost $20 a month to heat with electricity, I would've been hard pressed talking wifey into a new wood burner. Wood was a slightly different story. I put in $150 a cord (going rate around here) and came up with $10 a month. Who can honestly heat their home on $10 a month???
