Yesterday's Energy Usage

OK...so here's the last couple days of energy usage for my home:

Can you tell when the heat turns on when I get up?  Yeah...pretty obvious.  Not to mention that it's been in the 20s outside the past couple of AMs (highs around 50).  To set the stage...I currently have air source 2 heat pumps for heating and cooling, one upstairs and one downstairs.  They are old...11-12 years old.  The air handlers are even OLDER....they were MFRed in 1984 (my house was built in 1986).  Well...air source heat pumps really don't work under 32-35F.  So they are equipped with electric heat strips (10kW) for days of low temperatures.  Well...these heat pumps are just killing me.  Over the last two days I've used the following amounts of power according to TED:
Tuesday 1/4:  84 kWh
Monday 1/3: 68 kWh
Sunday 1/2:  32 kWh (low temp ~40F, high temp ~64F)
So, when I look at where my power is going....it's nearly all going to heating...with a significant chunk by the auxiliary heat.  There's some going to hot water (electric again) after showers, but generally that's short-term, but that still adds to the peaks.  If you compare to Sunday...when we were home all day, we used half as much power because temperatures were warmer which meant there wasn't a need for the auxiliary heat.

And before you ask...I do use programmable thermostats.  My upstairs heating temperatures moves from 62F (away/sleeping) to 67F (home/awake)...while downstairs I'm a little more 'liberal' at 62F to 68F.  As my wife says every winter, "say goodbye to this" as she bundles up.  If we have company (which isn't all that often), I may splurge and bump up the downstairs temperature to 69F.

Anyhow, "luckily" my air source heat pumps are dying, according to my HVAC tech.  I've already spent around $600 on those units since I've moved in (March 2010).  This is one of the main reasons why I'm going to replace that system with a ground source (geothermal) heat pump.  These units are somewhere around 3-5x more efficient at heating, 1.5-2x more efficient for cooling, and they can produce my hot water.  For more information see:  http://www.geoexchange.org/.  Fear not...I'll keep you posted when this endeavor kicks off.
