Show MORE COMFORT FOR LESS ' Hidden in the cold air is enough warm air to heat your house. Even when the temperature outside is well below freezing, the air contains con-tains heat that can be extracted from its icy surroundings sur-roundings and brought into your house. All it takes is a heat pump. The principle that makes a heat pump work is essentially essen-tially the same one that makes your refrigerator work. A heat pump requires certain cer-tain basic components: a coil and blower inside your house and another coil plus a compressor and fan, outside out-side your house. What circulates within the coils is a "refrigerant" that also acts as a heat-transfer medium. This refrigerant, circulating continually within the system, sys-tem, permits the heat pump to warm or cool your house automatically. In winter, outside air is drawn over the outside coil, where it is heated to a comfortable temperature and circulated throughout the house. You've probably noticed that your refrigerator gives off a little heat on the outside even though it s keeping things cold on the inside. That's because the circulating refrigerant is absorbing heat from inside the refrigerator and transferring transfer-ring it out into your kitchen. Now think of a heat pump doing the same thing, on a larger scale. Being reversible, the New Day Heat Pump made by City Investing's Rheem Air Conditioning Division also works in warm weather to remove hot, humid air trapped inside your house while circulating cool air.
