That's going to depend on a bunch of factors. I really don't have any idea right now.

If it ran 24 hours a day using 368 watts, that would be 8.832 KWh per day..
At $0.1661 per KWh, that's about $1.47 a day.

So if it runs 8 hours during a summer day? That's 49 cents..

If the average daily run time is between 8 and 16 hours a day, that would be nice.
Cheaper than burning $2 worth of fuel oil..

The cost of home heating oil here in MA has been slowly going up for years.
I don't expect it to get any cheaper over the next 5 or 10 years..


Even if the A7 wasn't useful during cold weather, we might still be
able to cut the amount of oil burned by a good percentage.
