As promised, here are the cumulative electricity and heating costs for our home from the first-of-Oct 2009 through end-of-March 2010. We replaced our heating oil-fired boiler/radiator system with a WaterFurnace 5 ton ground source heat pump/forced-air system last September. Although I wrote previously I was going to burn some wood in my wood stove, after we got over 6 feet of snow in one week, I couldn’t even get to what little wood I had cut for this winter. The amount of wood I burned this winter was negligible, which should be taken into account since I burned typically 4 to 5 cords each of the past 2 winters [2007-2008; 2008-2009]. This winter’s total electric bill was $1405.84. Of course, I bought no heating oil since that system is gone. I saved $1440.02 over the same months last year. I saved $1723.00 over the same period 2 years ago. My total tax credit for the system was $9964. The heat supplied by this system all winter was the most comfortable this house has ever been. The humidity level did get low … we didn’t switch the option to increase the humidity, but did use an electric humidifier we already had which helped to stabilize it more comfortably. We are very satisfied with this system. Note: my previous post indicated our Dec bill at $208.85 for 3 ½ weeks. That was an estimate. The actual December bill for 31 days was $259.57 as shown below. Remember, 2007-08 and 2008-09 include the cost of heating oil !!

[maybe some day I'll figure out how to set tabs in these windows !!]
Again, I didn’t burn any appreciable wood in my soapstone woodburner. I’m already getting well-stocked with wood for next winter, so my total heating costs should go even lower.
