Where There Is Condensation 



— there is need for a Morehead Steam Trap. Condensation in 

 steam lines is akin to matter out' of place — means wasted energy. 

 If your lines are sluggish — if your houses are not of uniform 

 temperature, write us. We guarantee to drain your lines per- 

 fectly — return the pure, hot condensation to your, boiler without 

 pump or injector or make no charge for the trial. Obey that 

 impulse — write now.

like to know. There is less than 500 

 feet of radiation. The trap used is the 

 Empire trap; the meter is the No. 2, 

 Model C, of the American District 

 Steam Co. L. M. F. 



The data furnished are not suflScient- 

 ly complete to indicate clearlv the 

 cause of the trouble. It is possible that 

 the supply main is not properly insul- 

 ated, so that most of the steam is con- 

 densed before it reaches the heating 

 coils, and it is also evident that the 

 amount of steam furnished is insufli- 

 cieut to heat the house. If the pipes 

 are cold, it seems likely that the trap 

 is not working properly and that the 

 water backs up in the coils as a conse- 

 quence. As nearly as can be ascer- 

 tained from the description given, 

 there are about 500 square feet of sur- 

 face in the mains and the same amount 

 in the coils, and even if the mains are 

 carefully insulated, the proportion of 

 surface in them is altogether too large. 

 A 3-inch pipe would answer the pur- 

 pose and, as it would contain only 

 about one-third as much steam, the rate 

 of condensation in the main would be 

 materially reduced. 



Of course the price paid and the 

 method of measuring the amount of 

 steam furnished will depend upon the 

 bargain that has been made. Ordina- 

 rily, only the amount condensed in the 

 coils is measured, aitU if any of the 

 water condensed in the main passes 

 over into the coils, a relief pipe should 

 be put in where the main enters the 

 house. 



THBEE CONNECTICUT HOUSES. 



Kindly inform me what size of hot 

 water boiler I shall require for a green- 

 house 35 X 100 and seven foct high to 

 ,the eaves, with 16 x 24 glass in the sides 

 land ends. How much piping will be 

 needed and how would you pipe the 

 house to obtain a temperature of 50 

 to 55 degrees in zero weather? Would 

 a horizontal boiler be more economical 

 than an upright one? The house runs 

 east and west, with the boiler house 

 at the northwest corner. I have also 

 two other' houses, each 20x50 and 

 eleven feet high to the ridge. These 

 run north and south at the west end 

 of the 100-foot house. Would it be 

 advisable to heat all three houses from 

 one boiler, providing the boiler is large

enough? If so, how large a boiler would 

 be, required? J. H. S. 



There will be no difficulty in heating 

 the three houses with one boiler. For 

 the larger house alone a boiler with a 

 rating of 1,500 square feet of radiating 

 surface will be required, or to heat the 

 three houses from one boiler a heater 

 with a rating of 2,400 square feet 

 should be used.
