PIPING IN WYOMING. 



I am building a range of greenhouses 

 and intend to use a tubular, horizontal 

 boiler, which was procured from an elec- 

 tric light plant. I do not know the ex- 

 act dimensions of the boiler, but it is 

 rated at eighty horse-power. How many 

 feet of glass is it capable, of heating in 

 this climate? Last winter the thermom- 

 eter registered as low as 45 degrees be- 

 low zero. How many 1-inch pipes will 

 be required to maintain a temperature of 

 60 degrees, with steam, in a house 

 21x100, seven feet to the eaves, with 

 glass in each end and two feet of glass 

 in the south side? The north side is 

 boarded. L. M. B. 



A boiler with a rating of eighty horse- 

 power will heat 16,000 square feet of 

 glass, even under the severe conditions 

 mentioned. For a house 21x100 feet, 

 about 800 square feet of radiation will 

 be needed, and this can be supplied by 

 twenty-four 1-inch pipes. It will be bet- 

 ter, however, to use eighteen 1 14 -inch 

 pipes. 



While it is always advisable to have 

 a boiler of ample size, to use one so out 

 of proportion as in this case will not be 

 economical in the amount of fuel con- 

 sumed. 



A NORTH CAROLINA RANGE. 



I have three greenhouses and expect 

 to build another. House No. 1 is 16x60 

 feet and four and one-half feet to the 

 eaves, with a foot and a half of glass in 

 the west side. At the front, or north 

 end, of this house is a new addition, 

 14x16, with 6-foot walls and three feet 

 of glass all around. At the south end 

 of this house is the boiler-room. Extend- 

 ing south from the boiler-room is house 

 No. 2, which is 16x56, with a 4 14 -foot 

 solid wall all around, except that there 

 is glass in the south end. House No. 3 

 is a separate house, 21x48 and five and 

 one-half feet to the eaves. This house 

 is west of house No. 2, at right angles 

 with it, and has two and one-half feet 

 of glass in the north side and east end. 

 The proposed house will be south of house

No. 3 and will be 22x48 feet in size. 

 I wish to rearrange the piping and 

 should like to use about 400 feet of 1^- 

 inch pipe which I have on hand. How 

 many runs of pipe and what sizes would 

 you recommend, to maintain a tempera- 

 ture of 55 degrees when the outside tem- 

 perature is 18 or 20 degrees above zero? 

 What size of boiler would be needed to 

 heat this range, including the proposed 

 house? Would a coil built in bricks an- 

 swer for a boiler and how should it be 

 constructed? G. J. S. 



For house No. 1, 16x60 feet, if to be 

 heated by hot water, it will be well to 

 use two 21/^ -inch flow pipes and six 2- 

 inch returns. The flows could be run 

 along the purlins and extended through 

 the 14-foot addition. To furnish the ex- 

 tra heat required on account of the glass 

 in the side walls and in the ends of this 

 house, the coils should extend along the 

 end walls, beginning close to the door on 

 each side. The same number of pipes 

 will be needed in house No. 2, 16x56 feet. 

 For house No. 3, 21x48 feet, eight 2-inch 

 returns will be required, in addition to 

 the two 2^ -inch flow pipes. 



To supply heat for these houses and 

 for the proposed house, 22x48, it will 

 be well to have a boiler rated for 1,500 

 square feet. While the first cost may 

 be slightly higher, it is generally more 

 satisfactory in the end if one of the reg- 

 ular greenhouse hot water boilers is

used, rather than a coil such as G. J. S. 

 mentions. 



THREE CONNECTED HOUSES. 



We are building three connected 

 houses, each 20x100, twelve feet to the 

 ridge and four feet to the eaves. How 

 many lines of 2-inch returns will be re- 

 quired to heat these houses to 50 de- 

 grees with hot water, in zero weather? 

 We intend to run two 2^-inch flows 

 along the purlins and place the returns 

 on the sides. What capacity of sectional 

 boiler will be needed? We are located 

 in the state of Washington. B. B. 



Each of the houses will require seven
