A heat pump is a machine that transports heat from one place to another using a mechanical system, where it can produce or sink heat. Current technology in pumping systems usually transfers heat from low-temperature areas to higher temperature areas.
Appliances such as refrigerators and air conditioners move heat from the inside to the outside while the cycle pump returns to transfer heat from the outside in providing thermal comfort.

Heat pumps provide an energy-efficient alternative to air conditioners and boilers in a climate that requires moderate heating and cooling. In summer, this type of pump transfers heat from the inside out which gives a cold environment inside.
Instead, the pump transfers heat into the house from outside during the winter. The most commonly used pump is an air source heat pump. These pump exchanges heat between the outside air and your home.
High-efficiency pumps can provide a cooling system that is better than standard central air conditioning. This ultimately results in less energy consumption and better cooling comfort in the summer.
Apart from these advantages, most high-efficiency cooling pumps have low efficiency at low temperatures, making them unusable in cold climates.
Pumps with higher efficiency can be achieved using a geothermal heat pump, otherwise known as a ground source pump. This system uses the land as a source for transferring heat.
