Heat pumps, as the term implies, transfer heat from outdoors to indoors. Really, it is that simple. Nothing magic here folks.
The problem with heat pumps is that is there is a severe shortage of heat, for instance, when it is 0 degrees outdoors, there is very little heat to pump indoors. Hence while heat pumps have marginal success in many of the southern states, NOT SO MUCH IN MAINE OR MONTENA. I really don’t think they will be so effective in places like major ski resorts.
And all these brilliant scientist are baffled at why people insist on choosing systems that work, you know, like oil, LP and natural gas.
I have a brilliant idea. Make these scientist spend two winters in north Idaho in houses heated with nothing but heat pumps. No cheating now. No heating elements, gas or electric. No fire places with the proverbial yule log on it. Well, maybe a couple for Christmas. Then ask them how much they like the heat pump idea.
