Hmmm, Today's modern heat pumps are pretty efficient and can operate efficiently at much lower temps than twenty years ago. One working beautifully here near Seattle where at my home the last couple nights it was down to 7F.. Not a problem and because the air was so dry (very, very low humidity) it never went thru a defrost cycle. The next gen heat pumps coming out this year will use CO2 as a refrigerant. Allowing higher COP's at much lower OAT's. No fossil fuels needed...... Oh by the way, Bob doesn't have an engineering degree. Clueless E

Good post, longz. A heat pump isn't what it's cracked up to be. Sure, it might be more efficient in milder conditions. But the upfront cost is just too high. It's the same deal with these high-efficiency water heaters. Nice but certainly not worth the higher upfront cost. And anything that "pays for itself in 10-20 years" isn't worth getting, unless you're like me and you can afford the latest-n-greatest technology for the sake of being eco-chic. Plenty of people here in the SF Bay Area are like that, by the way. But then again, we can afford to be. (Well, kind of, but that's another story.) Tenchusatsu
