Heat Pump Systems - There are different types of Heat Pumps in use in both the commercial HVAC heat pump markets and the residential HVAC heat pump markets. The two main types of heat pumps are the air source heat pumps and the water source heat pumps (or geothermal heat pumps). Within the water source heat pump types there are several sub-categories. Mechanically and electrical speaking, heat pumps all work the same way but use different methods of moving the heat from one place to another. Regardless of the type of heat pump it is, heat pumps are based on the theory of heat pumps that says heat can be moved from a warmer place to cooler place. Air source heat pumps are popular in southern regions where the temperatures in the winter are considered to be mild while water to air heat pumps can be used in any climate as long as there is a moderate (temperature) and reliable water source to move the heat from one place to another.
Heat Pump Types - There are different types of heat pumps available on the market today. A heat pump is an air conditioning unit that cools when the temperature is hot and heats when it is cold. There are many different types of these heat pump systems available. There is the geothermal heat pump. It can either utilize a series of closed loop water pipes buried in the ground or other methods of heat exchange. This process removes or absorbs heat for heating and cooling.
Air source heat pumps can be configured differently. One type of air source heating will utilize electric heating for backup heating while another may use a gas furnace for back up heating. These types of systems can also be split systems or package units and nearly all share a similar heat pump sequence of operation. A description of the various types of systems and how they work is below in this article on heat pumps types. These systems utilize similar heat pump components but differ in how the heat pump works.
