Mark,
I've been considering a heat pump HW tank. My current tank is close to
20 years old and probably will need replacing soon. Two big concerns I
have are
- how long is the heat pump mechanism warrantied?
- how noisy is it?
A third question is how long does it take to get hot enough for a
shower, if depleted? Assume 50F cold water.
In our case, the garage, where we have the HW tank, is under our living
space and very close to our master bedroom. I don't want to hear humming
through the floor.

Subject: [EVDL] Ot "heat pump" h20 heaters
Hi Lee etc
I have a GE GeoSpring "heat pump" hot water heater that uses 600w
instead of 4500w resulting in about 1/4 the monthly kWh usage for the
same btu h20 heating and dehumidifies the basement. It's used in any
climate as long as your underground basement is 12x12 or larger. GE
etc just takes their refrigerator compressors and puts them in
backwards so it's really not a heat pump, just marketing speak for
consumers. You have to hook up the pee line like on your a AC unit
outside or use a condensate pump. Typically a 3 year payback. AO Smith
and Siebel etc make also.
Have a renewable energy day
Mark
