The most common type of heat pump is an “air-source” system. “Split” air-source systems have an outdoor unit, which includes a compressor, outdoor coil, fan, and reversing valve. That unit is connected with refrigerant-filled tubing to an indoor component. The indoor unit contains a fan, indoor coil, which transfers heat between your house and the outside air.
Heat Pumps are ideal for climates with moderate heating and cooling needs, heat pumps offer an energy-efficient alternative to furnaces and air conditioners. Like your refrigerator, heat pumps use electricity to move heat from a cool space into a warm, 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; 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.
Heat pumps give off less heat at one time than does a conventional gas furnace.
This means that they offer a mellower type of heat, do not turn off and on with the same frequency as a gas furnace, and therefore circulate more air throughout the house.
They are controlled by the same type of thermostat used for forced-air systems.
If you heat with electricity, a heat pump can trim the amount of electricity you use for heating by as much as 30%–40%. High-efficiency heat pumps also dehumidify better than standard central air conditioners, resulting in less energy usage and more cooling comfort in summer months.
On really cold days, a heat pump must work especially hard to collect heat and the efficiency of most air-source heat pumps as a heat source drops dramatically at low temperatures, generally making them unsuitable for cold climates, although there are systems that can overcome that problem.
NOTE: Keep in mind, even with our state of the art, high efficiency, DC Inverter variable speed compressor systems, which have heating operating temperatures down to zero, the heating capacity drops dramatically at low outdoor temperatures, moving approximately 40% of the heating capacity at 10 degrees. We highly recommend, a supplement heater, perhaps
an oil filled portable heater with its own thermostat or installing a permanently mounted baseboard heater with high wattage outputs, for the colder climate areas.
