Notes For Buying Split Heat Pump Systems

Split heat pump systems
For climates with moderate heating and cooling needs, heat pumps offer an energy-efficient alternative to furnaces and air conditioners. The split heat pump systems are heat, air-conditioning and ventilation system (HVAC) divided between an outdoor unit and an indoor unit. Like your refrigerator, heat pumps use electricity to move heat from a cool space to a warm space, making the cool space cooler and the warm space warmer. During the heating season, heat pumps move heat from the cool outdoors into your warm house and during the cooling season, heat pumps move heat from your cool house into the warm outdoors. Because they move heat rather than generate heat, heat pumps can provide up to 4 times the amount of energy they consume. The two units are connected through the house by copper piping.

Heater during winter and cooler during summer
Freon gas absorbs heat from the air moving over the coil in the outside unit. The gas heats up to temperatures over 140 degrees F by moving through the compressor in the outdoor unit. The heated gas passes into the indoor coil via the copper piping. The fan housed in the indoor unit pulls the heated air through a grill. From the grill, the hot air moves through the coil housed in the indoor unit. The Freon gas absorbs the heat from the hot air moving over the coil. Moisture and heat are removed from the air inside of the home. Freon gas carries the heat through the copper piping to the outdoor unit's compressor. As the Freon gas moves through the compressor, it then passes through the coil. The heat moves through the coil in the outside unit, which then releases the heat to the outside air.

Studies of ground source heat pump cost
Studies show that approximately 70 percent of the energy used in a geothermal heat pump system is renewable energy from the ground. The earth's constant temperature is what makes geothermal heat pumps one of the most efficient, comfortable, and quiet heating and cooling technologies available today. While they may be more costly to install initially than regular heat pumps, they can produce markedly lower energy bills - 30 percent to 40 percent lower, according to estimates from the U.S. Environmental Protection Agency, who now includes geothermal heat pumps in the types of products rated in the ground source heat pump cost program. Because they are mechanically simple and outside parts of the system are below ground and protected from the weather, maintenance costs are often lower as well.
