WHAT HAPPENS TO YOUR ENERGY BILL AFTER INSTALLATION OF AIR SOURCE HEAT PUMP?
Air source heat pumps extract heat from the outside air, then use the heat to heat warm air convectors, under floor heating systems, radiators and provide hot water in homes. The heat is absorbed from the air into a fluid, the fluid thereafter passes through a compressor where its temperature is increased. It then transfers its increased heat to the heating and hot water circuits of a home. Air source heat pumps use the same principle used by fridges to extract heat from the things inside them. The air source heat pumps have the ability to extract heat from air even at low temperatures like -150c. They come in two main types namely: air-to-water systems that distribute heat through a home’s/premise’s wet central heating system and secondly the air-to-air systems that produce warm air which is circulated by fans to heat a home/premise. Air source heat pumps have the ability to provide efficient heating and cooling more so during summer. When they are properly installed in a home or premise, they can produce up to one and a half to three times more heat energy than the electricity they consumes. Therefore, they use very little electrical energy to produce a lot of heat energy. They achieve this because rather than converting heat from a fuel like in combustion heating systems, they move heat absorbed from the air.
Initially air source heat pump systems did not perform well in extreme cold areas or during extreme winters, thus people were forced to have gas heating as backup plans. But in recent times, heat pumps have been designed to meet the heating needs of sub-freezing winter temperatures. They can now work efficiently during extreme cold seasons thanks to reverse cycle chillers. Modern day air source heat pumps are more efficient in the electricity usage than in the old ones because of a number of technological advancements that have improved their features and consequently performance. They include; they have improved coil and electric motor and two-speed compressor designs, better control of the refrigerant flow to the indoor coil using thermostatic expansion valves, variable speed blowers that are more efficient and reduce the effects of restricted ducts, dirty filters and dirty coils and presence of copper tubing that are grooved in the pumps to increase their surface areas.
They have energy guide labels that indicate their heating and cooling efficiency performance ratings; this allows people to choose air source heat pumps that can save a lot in heating expenditures. Their heating efficiencies are indicated by the heating season performance factor (HSPF) which is the total area to be heated during a heating season, expressed in Btu, divided by the total electrical energy consumed by the heat pump system during the same season, expressed in watt-hours. Most of them have one coil indoors and one outdoors and supply and return ducts connected to central fins which are located indoors, yet others are packaged systems-have both coils and fans outdoors. These increase their efficiency and lower the electric consumption.
