The question I would ask is if your gas bill is that much of a problem, what
have you done to reduce your usage??
where are you located??
what appliances are you running??
how old are they??
what are their efficiency ratings??
FWIW, I installed a 4ton 14SEER dual fuel/hybrid system with 2 stage w/ECM
blower 80%AFUE gas furnace in my home here in south Mississippi last
January. My power bill for last month was $125 and my gas bill was only $37.
Compared to last year before I installed the new system, my power bill was
$178 and my gas bill was $72. I also installed a new gas water heater over
the summer.... that helped a lot too.
With only the water heater and gas clothes dryer, my summer gas bills run
$17/mo.... down from $25
========================================Actually Steve I also have a dual fuel 4 stage system and that's part of the
problem. Because it's a 2 stage HP I oversized the unit (compared to a
single stage). Because it's oversized, I can stay on HP down to ~20
degrees. Because I use so little nat gas, I'm permanately stuck in the
$0.45 per therm distribution charge. So my gas bill is relatively high
percentage of my heating bill even though almost all my heat comes from the
HP. That's when I realized the cost of the actual gas could be zero and I
still have a high gas bill.
