In reply to your request of Feb. 21 that we investigate the conditions of operation of the electric light, heat and power plant in Hull House, cor. Polk & Harrison Sts., we have to report as follows: -
From the data which we have been able to obtain, your estimate of 800 sq. ft. of direct radiation for the hot water tank in the basement coal room is approximately correct. The radiation for the dish washing and cooking apparatus, however, we estimate to be approximately 2500 sq. ft. instead of 400 sq. ft.
The question as to whether the coal consumption for the past four months has been extravagant for the work done is possibly an open one. We believe, however, that the amount of coal burned in order to heat and light the buildings was excessive.
Taking into consideration the facts that a temporary boiler was placed in the alley, that some of the steam pipes were uncovered, and that the return water of the heating system drained into the sewer for a time, we find a partial explanation of the large consumption of coal and consequent lack of economy in operation.
Now that the plant is completely installed, we believe that careful data, determined anew, will show that the plant is operating more economically than when the data, furnished us, was taken.
We do not understand that you desire us to go into an exhaustive, [page 2] quantitative test of the plant at this time, but rather to make a general investigation of the conditions of operation.
Hoping that the report submitted above will meet with your approval, we remain,
Yours very truly,
