Are heat pumps new?
No, they share the same basic technology as refrigerators and air conditioners which were invented over 100 years ago. Heat pumps were first manufactured over 50 years ago and in many regions of the world such as the Southern United States and Italy, heat pumps have been popular and well known for decades. Natural Resources Canada’s 1993 Survey Of Household Energy Use estimated that 2.9% of Canadian households used a heat pump as their primary heat source at that time, while the 2003 survey estimated that over 4% had heat pumps. And it has been in the period between 2003 and the present that the greatest increase in the popularity of heat pumps has occurred.
