flows and three returns of 4-inch pipe, 

 and two flows and two returns of a-rnchv 

 pipe. The next house has three flows and 

 four returns of 4-inch oipe. The middle 

 carnation house has nve &&nB gnd five 

 returns of 4-inch pipe." The north house 

 lias four flows and four returns of 4-inch 

 pipe. J^N_ . 



If the piping is in good order and 

 gives good service, it should do the work 

 in the new plant without addition or 

 modification. The rose house has radia- 

 tion which should hold a temperature of 

 65 degrees, and the carnation houses have 

 just about the right piping for a tem- 

 perature of 50 degrees. This is based on 

 good circulation and a temperature of 

 180 degrees in the boilers. You should 

 be able to heat the one large carnation 

 house more easily than three smaller 

 ones. L. C. C. 



HOT VATER FOR SMALL HOUSE, 



I am building a two-third-span house, 

 11x40 and eight feet to the ridge. The 

 frouth wall is four feet high and the north 

 wall five feet. I am going to keep a 

 general line of pot plants in it and will 

 heat it with hot water. I would like to 

 know if a "Wiiks heater, 20x42, will do 

 the work. I want to use a 2-inch flow 

 and IVj-inch returns. Please tell me how 

 to arrange the pipe and about what tem- 

 perature will be needed day and night. 

 I have 500 feet of liA-inch pipe and 100 

 feet of 2-inch that I bought cheap. I am 

 located in Tennessee. J. F. C. 



To pipe your house to maintain a tem- 

 perature of 65 to 70 degrees, which will 

 be desirable for a general collection of 

 plants, it will be necessary to use one 

 2-inch flow pipe under the ridge and ten 

 l^/L'-inch returns the length of the house. 

 If you wish to run cooler plants the 

 number of returns can be reduced to 

 eight, but ten will meet the conditions 

 for any plants that you will probably 

 wish to grow. If your boiler is rated to 

 ^arry 300 feet of radiation, it will be

ample. The plan above described con- 

 templates the use of an elevated expan-

 turn near the boiler. L. C. C. 



USING LARGE PIPE. 



Please give me information as to how 

 many 4-inch pipes I need to heat a house 

 26x118 in northern Illinois climate. I 

 want to heat to 60 degrees at 10 degrees 

 below zero. How should it be arranged! 

 The house contains two 4-foot benches 

 and two 6-foot benches. The house runs 

 north and south and the boiler-shed will 

 be at the south end. H. V. 



While I do not recommend the use of 

 4-inch pipe in houses over 100 feet in 

 length, unless artificial means of circu- 

 lation are provided, the following will 

 supply the necessary radiation with a 

 boiler temperature of 180 degrees and 

 normal circulation: Under these condi- 

 tions eight 4-inch pipes the length of the

house should supply the desired tempera- 

 ture. I should arrange to use two of the 

 pipes as flows and six as returns.

STEAM FOR SMALL HOUSE. 



I want to repipe my house. Can I run 

 a 2 V^ -inch flow about thirty feet through 

 a shed and across the end of the green- 

 house 11x90, taking off under each of the 

 two benches a 2i^-inch pipe to run to 

 the far end of the house and there divide 

 to feed three 1^-inch pipes under each 

 of the two benches? All six 1^4 -inch re-
