Anyone have thoughts about heatpump water heaters which take teh heat out of the air to heat the water?
A heating system using a heat pump has the unit outside the home, thus removing heat from outside the home and bring it inside. Makes sense right? So why would you wish to heat water by taking heat out of the air INSIDE your home, thus cooling your home and having your heting system have to expend energy to replace the heat.? That makes no sense to me. Of course in the summer, it would be ok and might save you energy (money?) over a traditional hot water heater. But six months out the year, it would be a wash at best. If this is not that case why would you not put your heating heat pump unit inside the house. I think the answer is obvious.
