|A Heat Pump to Warm Your House in a Healthy Way|
To begin with, the main task of a heat pump is to transfer a certain amount of heat energy from a source that is already at a lower temperature to a sink which is at a relatively higher temperature. In this case, the source is the exterior surrounding of the house, and the sink is the inside of the house.
This direction of heat flow, which is opposite to the natural spontaneous direction of heat flow, is carried out with the aid of mechanical energy, which in turn is derived from a source of electric energy.
A heat pump is energy efficient in the best possible manner, and expends two to three times more energy on the transfer of heat, than the amount which is actually supplied into the machine.
