The first heat pump was invented in 1948, when a homeowner decided to salvage the warm water from the operation of a deep frigid freezer, however within a year, the homeowner replaced his coal heating system with his heating innovation. However, heat pumps would become popular until the 1974s. They gained attention during the oil crisis because the system runs strictly on electricity. Heat pumps don’t burn fossil fuels to generate heat. Instead, the operation takes fortune of ambient heat found in outdoor air even during colder weather. This heat is pulled out of the air, compressed to a warmer temperature & delivered into the house. Heat pumps avoid problems with reddwelling gasses & combustion byproducts. They don’t produce carbon monoxide, carbon dioxide, formaldehyde or fumes of any kind. The operation doesn’t cause troubles with overly dry air. During the warmer season, the heat pump literally reverses the flow of refrigerant. The system acts much like a refrigerator in that it removes heat from the indoor environment & transfers it outdoors by way of refrigerant… Electric heat pumps are far more energy efficient than gas heating systems or conventional cooling systems. While they cost more to purchase & install, the savings on running costs abruptly helps to reuse the investment. Plus, the single unit fulfills two tasks. The heat pump handles both heating & cooling, supplying a year round solution. These innovations are especially safe, disinfect & quiet. They are beautifully environmentally friendly… Modern heat pumps feature something called adaptable-speed technology that allows an automatic adjustment of output someplace from forty to one hundred percent capacity. By supplying only the precise amount of heating or cooling necessary to maintain consistent indoor temperature, the heat pump minimizes energy consumption.
