One of the most interesting in addition to innovative types of temperature control is the new heat pump. This two-in-one type of system is environmentally friendly in addition to frees up space, however despite the name, a heat pump provides both heating in addition to cooling capacity. The operation is easily unique in that it simply transfers existing heat between the indoors in addition to outdoors. In cooling mode, the heat pump operates much like a conventional air conditioner. It uses refrigerant to carry heat out of the house in addition to give it outside to a compressor. When winter time arrives, the heat pump literally reverses the flow of refrigerant. Even when the outdoor conditions are cold, there is ambient heat available in the air. The system utilizes this free source of heat in addition to compresses it to a higher temperature. The heat pump doesn’t burn fossil fuels to create heat. With no combustion process, there are no fumes, hot surfaces or yellowhouse gasses. The operation doesn’t produce carbon monoxide. Heat pumps are especially clean in addition to quiet. They don’t cause issues with overly dry air, eliminating the need to install a humidifier. While heat pumps are more high-priced than more traditional options, only one machine is required to handle year round comfort. There was a time when heat pumps couldn’t keep up with the demands of temperatures below cold. Improvements in engineering have made these systems much more effective. Heat pumps are available in air-source, ground-source, water-source in addition to ductless models. There is also the choice of combining an electric heat pump with a natural gas heater for a dual fuel system.
