Electricity on New England Farms

Farm No. 7. This is also a circulation type heater connected to a 40-gallon in- 

 sulated kitchen range boiler, which furnishes water to the kitchen and bathroom. 

 It is used as an auxiliary and during the hot summer months. During the greater 

 part of the year the hot water is supplied from a water front in the firebox of 

 the regulation kitchen range. The current is controlled manually. 



Farm No. 6. As in the first case, this is a complete unit consisting of a 15-gal- 

 lon insulated tank with automatic and manual current control. The heater is 

 located in the basement and furnishes water to the kitchen and bathroom located 

 on the floor above. The run of pipe from the heater to both of these locations 

 is particularly long and. at the same time, these pipes are exposed to quite 

 cool temperatures the year around. Both intermittent and continuous opera- 

 tion have been employed, the latter to supply 24-hour service. This is the 

 severest test to which any of the heaters have been subjected, and is at the 

 same time typical of a type of service which many people have come to expect. 



Results are given in Table 13. 



The heaters have given a high degree of service and are considered very de- 

 sirable and efficient from the mechanical and electrical standpoint. 



The cost of operation for the type of service which the people are accus- 

 tomed to, however, is excessive. 



The circulation-type heater that can be attached to, and thereby make use of, 

 the present boiler equipment is favored because of its lower first cost and ap- 

 parently lower cost of operation. Insulation of storage tanks and possibly pipe 

 lines is an important point. 



Particular pains should be taken to locate the heater in a central position, if 

 possible, with respect to the points where the water will be used in order to 

 cut down the length of pipe exposed to radiation. Exposure of these pipes to 

 cold should be avoided.

Washing Machines. The washing machine is considered important on the 

 farm where washings are large and heavy and access to commercial laundries 

 often impossible. All farms in the experimental group are equipped with elec- 

 tric driven washing machines representing cylinder, vacuum cup and submerged
