786 CHAPTER 56 1960 Guide pump installation, or may be a self-contained domestic-water beat pump. Various designs of self-contained domestic water heat pumps are available, and one particular arrangement is shown in Fig. 17. Hot water beating by means of a beat pump is not yet ad visable where high water temperatures are desired. This is due to the fact that higher water outlet temperatures result in lower coefficients of performance. For coefficients of performance of 4 or higher, the heatpump water heater may be more economical to operate than a conventional water heater. Although the first cost of domestic hot water heat pumps is somewhat high, they have the advantages of operating with out products of combustion, odors, soot, or chimney. A further advantage is that they may be used for cooling pur poses. With a coefficient of performance of 214 to 3, water temperatures of 140 to 150 F may be obtained.' REFERENCES 1R. B.
