If I consider my house was in Huston (1900 sq feet 1972 ranch with loft), and I base it on the last 12 months weather performance from the Huston Airport..
If I use my utility rates:
$1.11 per therm for gas
$0.093 per KWh for electric
Total cost for heating per year with HP plus Gas Backup is $165
Total cost per year for pure 92% gas heat is $250
Total cost per year for pure baseboard electric heat $564
Total cost for HP plus Electric Backup is $196
Now in my area (Portland OR) We do much more heating during the year than Huston. I spend $607 per year on my 14 SEER HP + 92% Gas setup and I was spending $928 on pure 92% gas setup. So in my area heat pump makes a lot of sense $320/yr pays stuff off a lot faster..
In Huston, you are going to have the occasional 20 degree day in the winter and you'll have to use some kind of backup heat. So you'll need resistive or gas/oil backup heat anyway for those couple days a year. So you can't get by just installing a heatpump with no backup heat. That is probably why no one installs heat pumps there, because you're only saving $85 a year owning a heat pump. But with everyone freaking out about energy these days, I'd think you'd have some more people going after that 85 bucks a year..
