Heat Pump Problems | HVAC Heating & Cooling - Heat Pumps are very popular especially in the South where air source heat pumps are mostly favored over straight air conditioners with a gas furnace for heating. With a heat pump, one system can provide heating and cooling. Some people rely on a geothermal heat pump system or a water source heat pump. A geothermal heat pump extracts heat from the ground instead of the air like an air source heat pump works. (more…)
Geothermal heat pumps use ground water or water circulated through pipes to exchange heat with the earth. Geothermal, versus air source heat pump systems, use the earths natural temperature to exchange heat and provide heating and cooling. The temperature of the air varies widely with the weather. Whereas the temperature of the earth is nearly constant. This makes the use of a geothermal system ideal for heating and cooling. It also costs less in energy use because of the constant earth temperature versus the widely varying temperature of the outside air. Consequently, geothermal systems make sense and can save lots of money in energy use.
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.
