| Nov 13, 2012 at 20:58 | comment | added | mac | @MattAdams: a heat pump and a dedicated A/C are so similar in "cooling" operation as to not warrant any further thought. | |
| Nov 13, 2012 at 20:57 | comment | added | mac | @bcworkz indeed. Ground source or geothermal heat pumps are fantastic, but not yet in widespread use, therefore my assumption was that the OP was contrasting a "conventional" air source heat pump with resistive electric heat. There are certainly alternatives that are more efficient than either of these two options. | |
| Nov 13, 2012 at 20:56 | comment | added | Matt Adams | Good notes here. Now any thoughts as to the AC unit in the summer? Would a combo unit be less efficient than a dedicated AC? or is not that different? | |
| Nov 13, 2012 at 20:37 | comment | added | bcworkz | Cold air will not be an issue in Phoenix, but generally speaking, let's not forget there are other sources of free heat than outdoor air. It will obviously cost more to access it, but can be less expensive than relying on resistive backup heat. I'm thinking primarily ground water or the ground itself as heat sources, but solar heated mass could be a possibility. | |
