MENDING A BOILER. 



The hot water boiler installed in the 

 plant of Fletcher C. James, at Des 

 Plaines, 111., gave out in zero weather. It 

 was found that the inside shell was 

 rusted through and a hole was found in 

 the back of the boiler in such a position 

 as to make it impossible to patch it. The 

 following ingenious idea occurred to the 

 Garland boys. An opening was drilled 

 through the top of the boiler just over 

 the hole. After the water was let out 

 of the boiler a funnel was inserted and 

 several bags of dry cement were poured 

 in and water was immediately let into 

 the boiler. The cement was packed down 

 with a stick and the opening in the top 

 closed up with a wooden plug. The boil- 

 er was found to be perfectly tight and 

 heating wa§ resumed. 



BOILER CAPACITY. 



I have an upright boiler rated to carry 

 800 square feet of radiation heating my 

 dwelling house of four rooms, each aver- 

 aging 12xli!. In addition to this, can 

 I heat a greenhouse 20x40 and maintain 

 a temperature of 56 degrees in Kansas 

 climate? I have four runs of 4-inch pipe 

 on each siue of the greenhouse, or 350 

 feet altogether. W. P. E. 



If the boiler in question is rated to 

 carry 800 square feet of radiation and 

 the house is no larger than you say, the 

 boiler working at full capacity should 

 be able to carry the four rooms of the 

 house and the 350 feet of 4-inch pipe. 

 It will not be safe, however, to increase 

 the load. This amount of piping is am- 

 ple for the house in question. L. C. C. 



HEATING THREE GREENHOUSES. 



I am about to construct three north 

 and south houses, each 100 feet long. 

 The two west houses are to be connected 

 and the other one is to be partitioned off 

 for roses, etc. They will be heated with 

 hot water and the boiler-room will be a^ 

 the northeast corner. I would like to 

 know if I can run a 3-inch header the 

 width of the houses and run three 3-inch 

 flows, one in each house, off of the main 

 header, and if the water could be forced 

 up hill to the other end, the returns 

 gradually dropping to the boiler. This 

 radiation will be sufficient in our mild 

 climate. H. H. P. 



You will get greater satisfaction from 

 carrying each of the three flow pipes 

 direct from the boiler. You can arrange 

 it as you suggest, but trouble frequently 

 occurs with pipes so arranged; the cur- 

 rent of hot water gets started in one set 

 of pipes and actually passes the others 

 without heating them to amount to any- 

 thing, thus giving a very uneven distribu- 

 tion. If each flow is taken off the boiler 

 direct there is no chance for this uneven 

 distribution, provided the pipes are prop- 

 erly graded. L. C. C. 



TO IMPROVE CIRCULATION. 



My new greenhouse is 26V^x80, with 

 an addition 19x20 at the rear. There 

 are three and one-half feet of concrete 

 and three and one-half feet of glass on 

 each side. The houses are fifteen feet 

 to the ridge. The potting-shed and 

 boiler-pit are at the rear. A forcing

house 16x20, five feet high on the south 

 side and twelve feet high on the north 

 side, joins the potting-shed on the south. 

 I have five flows and seven returns in 

 the greenhouse, all 3% -inch pipes. There 

 are five open tanks at the east end. 

 There are two flows and two returns in 

 the forcing house and one tank. I am 

 obliged to cut off the heat from the 

 forcing house in order to heat the green- 

 house. When it is 4 degrees above zero 

 outdoors the thermometer registers only 

 40 degrees in the forcing house, the same 

 in the east end of the greenhouse, and 48 

 degrees in the west end. When it is at 

 zero outdoors it is only 48 degrees in 

 the greenhouse, with the forcing house 

 cut off. 



I have a Model No. 5 sectional hot 

 water heater, rated to heat 1,700 feet of 

 4-inch pipe. The boiler is in a pit seven 

 feet below the flow pipes. The stack is 

 12x12 inches inside, and twenty-four feet 

 high. There is a fine draught. I burn 

 enough coal to heat a larger building. 

 Must I get a larger boiler or put in more 

 pipes? I would like to turn heat into the 

 forcing house as soon as^ possible in or- 

 der to get lilies out for Easter. H.

Your boiler should be large enough to 



handle the piping you have upon it if it 

 is equal to its rated capacity. The 

 quantity of piping in each house should 

 maintain 60 degrees of temperature if 

 everything were properly arranged and 

 the circulation good. If you can take 

 each main flow off near the boiler, in- 

 stead of dividing the flows up some dis- 

 tance away from it, I think you will 

 get better service. I would also suggest 

 that the two side flow pipes which are 

 taken off at the jog in the main house 

 be converted into returns and that the 

 main flow be broken up only at the east 

 end of the house, there to return by five 

 returns instead of three as at present. 

 The circulation will be better with this 

 modification. The flows supplying the 

 side coils should each go back to the 

 boiler and be fed from separate open- 

 ings, or from a manifold close to the 

 boiler. There is too little opportunity
