Reply to comment by modernhomeowner in Does anyone have a ground source heat pump? What is your experience like? by Theredsoxman

One extra thing I noted in my research. My gas furnace is fairly efficient, but it's using plenty of power too. Using June as a base for least amount of energy used, I estimate it cost me about $148 last February (573 kWh) just to power the furnace not including the gas. Ironically, our window ACs jump to similar number in the summer. It's very hard to lock down a super accurate number, but I'm confident it's in that ball park.

Electric for me is about $0.25 per kWh (even being partly sourced by National Grid)

Gas is $2.15 per therm when you stack delivery and usage.

We'll see how it goes. Thanks for the math and insight.

If you have a condensing gas furnace, I would not replace it until it reaches the end of it's life. They're fairly efficient. MassSave is doing a good job but with the increasing price of energy I wouldn't want to be locked in until things settle down. Oil I would switch in a heartbeat. I have heard at a convention that restrictions will increase for commercial usage at some point.
