My primary heat source is a heat pump. In SE pa (PECO Electric) you get a discount on electric during the winter if you have electric heat, and a heat pump qualifies as electric heat. My electric bill peeks in july/Aug, then Dec/Jan, both around the same amount. The heat pump does not have Electric backup elements, the backup is Oil heat. I have the cut over set at 20deg, but once it's getting that cold I use wood or coal. Wood is free, but as others say it's work cutting/splitting it, plus the storage requirements are pretty large if you plan on having dry wood during the winter.
When I was just oil heat, I used to burn 400-500 gallons of oil to keep the house at 68deg. Since I installed the Heat Pump I am only using 75 gallons per year. I have always run computerized thermostats, cutback 62 in day (nobody home) and 65 at night. in the peak of winter, my electric bill is maybe $100.00 higher then the spring/fall. Since my heat pump/AC coil is mounted on top of my Jenson 24 stove, my electric savings by burning wood/coal is only from not running the outside AC compressor. Out of that $100 extra per month electric cost, can I assume the fan cost $25.00 to run, and compressor cost $75.00?
Now I have been burning 50 lbs of coal per day (and could use more if I put my mind into keeping it running)
50 lbs @ 7.50 bagged x 30 days $225.00 + the above $25.00 to run the stove fan = $250.00.
anyway I look at it, it cost me more money to burn coal then use the heat pump/oil backup.
what am I missing? Sure I could buy coal by the ton by picking it up (I live just south of coal towns), but even at $140.00 per ton that's $105 per month for coal and $25.00 to run the fans = $130.00. Sound like break even if you add a couple gallons of oil in the mix.
Now once electric deregulation screws us all, coal will be the king!
Coal at 140 a ton
# 2 Fuel Oil would need to be 80 cents a Gal
Electricity would need to be 2.50 A kWh
Propane 55 cents a gal
Natural gas 60 cents per therm
Corn 1.90 per 50lbs
Wood pellets 95.00 a ton
Fire wood 105.00 Per cord you need 24 x 10 x 6 of wood to match a ton of Anthracite coal
Your paying 7.50 a bag 50lbs that is 300 a ton
Now oil will have to be 1.70 a gal
Electricity would need to be 5.25 A kWh
Propane 1.20 per gal
Natural Gas 1.30 per therm
Wood Pellets 205 a ton
Corn 4.05 per 50 lbs
Fire wood 222.50 Per cord Don't forget 24 x 10 x 6 to equal one ton of coal
