Heat pump water heaters are fine during the summer when you need to exhaust heat from your indoor space, but in winter you need to provide heat from other sources to replace the heat sapped by the heat pump. So payout will depend on your client's location heating and cooling degree days.

Wanted me to confirm that it would save him kwh per year over a standard tank unit. Yes it will, or so all the numbers say for his area etc. But I cannot figure out ( or find out) how to compare the energy factor 2.2 in full heat pump mode vs the .91 in electric element mode? Anybody know how to do this? thanks, jay peltz power _______________________________________________ List sponsored by Home Power magazine List Address: RE-wrenches@lists.re-wrenches.org Options & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out participant bios: www.members.re-wrenches.org _______________________________________________ List sponsored by Home Power magazine List Address: RE-wrenches@lists.re-wrenches.org Options & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out participant bios: www.members.re-wrenches.org
