I just took another look at that NStar bill, ( I like to bore my wife with numbers).
using last June as a baseline shows that non-Sanyo use is about 5496 kWh per year (458 monthly).
Adding up the real use during the last 12 months, the total is 9,353 kWh..

The Sanyos seem to be using up 3,857 kWh per year.
At 16.61 cents per kWh, that's about $640.65 per year ($53.39 per month).

So, we are living in comfort for about $1.75 a day..

It seems this also includes heating our hotwater since August 2012..
(The A7 ASHP is not included in the June 5496 baseline calculation).
