FEBRUARY 19 56 business review I ■ FEDERAL RESERVE BANK OF PHILADELPHIA THE HEAT PUMP The heat pump is a climate machine that automatically makes your house a comfortable home through all kinds of weather. Using only electricity and air or water, it warms your house in winter and cools it in summer. It's safe, clean, and reliable. Yet to come is mass production needed to cut the cost and widen theimarket. THIRD DISTRICT BANKING— 1955 Record increase in bank loans partly offset by reduction in investments.

Like many other inventions, the heat pump had its origin in Europe where it appeared shortly after World War I. There the early in stallations were industrial applications, especially in certain chemical industries, in paper mills, and in sugar refineries where compressors were used to generate heat for drying purposes. The use of mechanical devices to heat or cool buildings had to await the arrival of low-cost electricity. Initial efforts were directed at sum mer air conditioning, and unit air conditioners cooling one room only made their appearance in the 1920’s. In the early thirties, engineers in cooperation with electric utilities, began experi ing up dealer organizations to bring the heat pump to the attention of the public. Precisely how many heat pumps are being produced or how many are now in use, no one really knows. One reason is the comparative youth of the product which still has no estab lished channels to collect reliable statistics, and another reason is the rapidly growing acceptance of the product. Prior to 1954 it was a simple matter to keep track of the relatively few instal lations; most of the companies knew where they were and followed them closely. However, with the tremendous expansion of sales during the past two years it was no longer possible to do this. Such records as there are show that almost two-thirds of them are in private homes and the menting with heat pumps for heating and cooling others in commercial establishments.

That includes not only the heat pump itself but also the necessary wiring and duct work for an air-to-air type of installation. In Florida, where watercooled heat pumps pre dominate, an installation for a small home costs only $1,700 including the NOTE— Map includes 2,076 installations for which exact locations have been re ceived by Joint AEIC-EEI Heat Pump Committee as of May 1955. well.

Preliminary tabulations, ad justed for bank mergers, show total income of $293 million, 8 per cent more than in 1954. More than half of this increase was absorbed by rising expenses— salary and wage payments, in terest on deposits, and other items of outgo— but a sufficient amount remained to add ma terially to current earnings after expenses.
