A heat pump is an electric cooling and heating system applied to compress and decompress gas to heat or cool a house. This mechanical device pumps heat from a cooler to a warmer emplacement and may extract heat from air, water or the earth. Heat pumps functions like an air conditioner in the summer and an electric furnace in the winter, thence encompassing both a heating and cooling unit in one device. The COP, or coefficient of performance, which calculates the symmetry of heat output to electric power consumption, measures the performance of a heat pump. Heat pumps are the most resourceful form of electric heating in moderate climates, and cool a house by gathering the heat inside the house and efficaciously pumping it outside. There are three types of heat pumps that one may install: air-to-air, water source and ground source. Heat pumps may gather heat from air, water or ground and may implement the same to heat or cool your home. When installing a heat pump at home, one will have to consider using an energy-efficient heat pump system, keeping in mind the climate of the region. For instance, air source heat pumps are a good option for mild and moderate climate regions, and ground source or geothermal heat pumps are effective in climates with similar heating and cooling loads. The most mutual types of heat pumps are the air-source and ground-source heat pumps. Although ground source heat pumps are more highpriced to install, they are more effective and less noisy. However, to make heat pumps work efficiently, they must be installed properly, and one ought to choose the right sized pump that may fulfill the heating and cooling demands of the house. While selecting a heat pump one must buy a device with a higher Heating Seasonal Performance Factor, or HSPF. The pumps ought to likewise be fitted with demand-defrost control, which minimizes the defrost cycles and reduces supplementary and heat pump energy use. Heat pumps are much more cost-effective then other traditionalisti heating devices, and are also getting more normally applied to heat swimming pools, and hot water for household use. |
