New heat pump saves some money..

We installed the Sanyo heat pump on 11/05/09 and have been using it to heat the house every day since.

I've been looking at the bills and just read the meter for December.
(Meter is read around the 20th to 23th every month).

Nov 2008 859 kWh $172
Nov 2009 632 kWh $129

Dec 2008 831 kWh $167
Dec 2009 745 kWh $150

No more resistance space heaters this year. Instead, we are using the Sanyo.

Plus, we are saving 2 or 3 gallons of oil a day too. The burner motor
is running a lot less and the circulator pumps never come on.

Oil Use:
We burn oil to heat the hot water. Our 76 gallon burner is rarely used for space heating.
The only time we have used the oil heat, is during heavy snow storms
and when the temperatures are going down below 15 degrees for more than a couple of hours..
Not using the circulator pumps, but just opening the Free-Flow valve on
the Taco check-valve. That allows limited amount of BTUs to flow up into the house.

Hybrid Mode: Oil & HP
Free-flow heating (baseboard feed using convection) works very nicely
with the Sanyo heat pump when the outside temperature is under 15 deg.

If the outdoor temp goes above 20F for a few hours at night,
the Sanyo goes into low-mode and the house starts getting
a little too warm for comfortable sleeping. (The new attic insulation is working?)
