The heat pumnp is ia sense a solar device, ac- cordlng to the Air- Condltioming and Reëfri-." geration Institute (ARI) because it collects "free" heat from the outside air and converts it into heated air for. your home. This "free" heat is generated and renewed each day when the sun's rays strike the earth and - its .atmosphere.-. Thus in a sense:the ear- thi itself is» a-."solar: collector" - and the heat pump is an efficient meansof collecting the heat' generated 'by the' Sun. Because the heat pump collects heat from a low-temperature source <air or, water) rather, than a high- temperature' -source (fuel 'combustion) it's becoming an Important element'i .solar and other types of' nergy- conserving heating. syÉý- tems, says 'ARI.
