If the Sanyo keeps working, I foresee using very little oil during the coming years.

With NStar charging about 20 cents per kWh, my single compressor Sanyo seems
to be burning up about 1/4 to 1/3 the money needed for oil heat alone.

It's April, but still cool around here. So we are still heating the house.

And, we are using less than 4 kWh per day..

So, even if NStar is someday forced by Cap-n-Tax to increase our rate to $0.40/kWh
we will still be saving money using the Sanyo mini-split.
(And, I'll bet that oil prices will not have dropped)..

Maybe by then, my wife will become more accepting of PV on our roof..

This week, we saw a local install by these guys..
Where We Work - Massachusestts and New England - SunBug Solar

It sure looked sweet to these old eyes..

I have a feeling that even a small array on my small roof would pay
for heating & cooling this small house..

IMHO, the inverter type mini-split ASHP is nearly the equal of GSHP
when used in the Boston area. But, it's the installer cost that makes
the old GSHP take a lot longer before break-even.
