Why heat pump is an economical machine


All machines manufactured to this day in order to generate heat are efficient less or equal to a unit. This means that a machine (a boiler, an electric heater, etc.) will consume at least 1 calorie of energy to generate 1 calorie.
As a heat pump removes heat rather than generates it, it will consume much less energy than 1 calorie in order to remove it from the environment into your house.
