Here is an interesting article on heat pumps, primarily in Norway. Important points are that Norway trained workers to install them, that heat pumps work reasonably well at low temperatures, and because they act as an energy multiplier there are reduced emissions even if fossil fuel is the energy source for electrical generation. Norway prices fossil fuels so that heat pumps will be the cheapest way to heat your house. Canadians reading this will recognize this as a carbon tax.
We've had a heat pump for at least 5 years and think it's great. Our coldest nights here are occasionally -10C (14F) and it's still working fine. Our electricity is primarily from water power.
