STEAM FOR ONE HOUSE. 



What is the best way to pipe a house 

 27x64 feet, for heating with steam? I 

 have some 1-inch and 2 V^ -inch pipe. 

 Would the 2*4 -inch pipe do for the 

 flow? H. J. L. 



The 2^ -inch pipe will be large enough 

 for a riser, and if 1-inch pipe is used 

 for returns it will require about 1,300 

 lineal f eet^ to give a temperature of 60 

 degrees in your Indiana climate.

HOT WATER RADIATION. 



I am going to build an addition to 

 my greenhouse, 20x50 feet, running 

 east and west. I am heating with hot 

 water, and would like to know how much 

 radiation I must put in to keep th6 

 right temperature, from 55 to 60 de- 

 grees, in Wisconsin climate. P. D. 



An even-span house, 20x50 feet, piped 

 to carry 55 to 60 degrees at night in 

 your climate, should, if piped with 

 4-inch pipe, carry 400 lineal feet; piped 

 with 2-inch, 660 lineal feet ; and if piped 

 with 1%-inch pipe, 800 lineal feet of 

 pipe, for hot water. L. C. C. 



FROM STEAM TO HOT VATER. 



I want to change the heat in two 

 greenhouses, 20x80 feet, with glass in 

 the sides of the west house. The houses 

 run from north to south, with the pot- 

 ting shed and boiler house on the north 

 end. We have a tubular boiler, 36 in. 

 by 14 ft., with thirty-two 2V4-iDch flues. 

 The boiler is set in brick, and the top 

 of it is below the floor level of the 

 houses. At present we are using steam, 

 with piping as follows: In the east 

 house there are ten runs of 1%-inch 

 pipe, five on each side, with a 2-ineh 

 leader overhead to feed them; four runs 

 of 1-inch pipe in the center, all re- 

 turning direct to the boiler. The west 

 house has a 2-inch leader to the front, 

 branching in 1^4 -inch pipes to one radi- 

 ator on each side of six pipes, extending 

 the full length of the house. We want 

 to change to hot water and use as much 

 of the pipe we have as possible. 



N. a. N. 



If you add eight more runs of 1^- 

 inch pipe in the house piped with that 

 size, so as to make eighteen in all, and

Gentlemen:— You can Birongrly and unhealtatlnrly recommend the 

 "Eclipse" piston type reduclnr valve to flortsts. We have two purchased 

 of you last year. Ws would not have them out for double their cost and 

 find them as sensitive as a watch. We will be in Chicaro soon to take up

add another 2-incli riser to carry nine of 

 these pipes, you can heat the house with 

 hot water. The other house can be piped 

 with the same amount of pipe, or 2-inch 

 returns can be substituted for the 1 Cl- 

 inch piping, in which case you should 

 use two 2-inch flow pipes and fourteen 

 2-inch returns. I do not think it wise to 

 use the 1%-inch pipe in a hot water 

 system of this length, as the circulation 

 will be too slow; 2-inch pipe all through 

 will be an advantage. I should not dis- 

 card the 1%-inch pipe, however, but 

 treat the house as suggested. L. C. C. 



STEAM IN WESTERN ONTARIO. 



We have a two-span greenhouse, 43x 

 150 feet, practically one house, lying 

 east and west, and propose to put in a 

 furnace on the north side. Our boiler 

 is eight feet long by thirty-six inches 



diameter, and has thirty-three tubes. The 

 fuel is coaJ. What is the best way to 

 heat it, with the smallest pipe possible, 

 running two circuits, one east and one 

 westt We propose to ^ink the boiler 

 six feet, the flow pipe in that case be- 

 ing just about level with the ground. 



C. & C. 



The houses in question, 43x150 feet, 

 will require about 2,400 square feet of 

 radiation, which, if supplied by using 

 2-inch pipe, will require nearly 3,900 

 lineal feet of such pipe. The house can 

 be heated by using four 3-inch risers 

 from the boiler, one running under the 

 ridge of each house from the boiler, lo- 

 cated at the center, to the far end of 

 the house and each riser there dividing, 

 to return by thirteen 2-inch pipes. This 

 is equivalent to two 3-inch flow pipes 

 the length of the house and twenty-six
