Greenhouse Heating. 



A CHANGE IN SIZE OF FIFE. 



We wish to replace some 4-inch cast- 

 iron pipe with 2-inch wrought-iron 

 pipe. Please tell us how many runs 

 of 2-inch returns will he required to 

 take the place of the following 4-inch: 

 Four 4-inch pipes under each of two 

 benches and five 4-inch under another 

 bench. We intend to use 2-inch for 

 returns under the benches. How large 

 should the feed be for each of these! 

 The first two coils are eighty-five feet 

 long and the other is 100 feet long. 

 All the flows will be taken off from a 

 large main flow at the end of the 

 houses. J. N. C. 



As a rule it will be advisable to 

 substitute two 2-inch pipes for each 4- 

 inch, so that there will be eight 2-inch 

 pipes under two of the benches and 

 ten under the other. A 3-inch pipe 

 will be needed to supply each of the 

 coils. If overhead flow pipes are run 

 through the house and connected with 

 the coils at the farther end, the num- 

 ber of the 2-inch returns in each coil 

 may be reduced by two. 



If 21/^-inch flows are used, there 

 should not be more than four 2-inch 

 returns in each coil. In that case, 

 five flows and five return coils of four 

 pipes each will be required. 



IN SOUTHWESTEEN OHIO. 



Please give me a heating plan for a 

 greenhouse of the following dimen- 

 sions: It is 30x50 feet, fourteen feet 

 to the ridge and has 6-foot walls, with 

 two feet of glass in the north wall 

 and three feet of glass in the south 

 wall. The east gable is glass; the west 

 end adjoins a stable, which will be 

 used as a boiler room. Hot water heat 

 will be used. The boiler pit is three or 

 four feet deep. The temperature de- 

 sired is 60 degrees when the outside 

 temperature is at zero. What size of 

 expansion tank will be necessary! 

 iShould it be put above the boiler or 

 can it be put in the greenhouse! The 

 house will contain five benches, three 

 of them five and a half feet wide and 

 the other two three feet wide. Will 

 a boiler rated at 3,050 feet be much too 

 large for a house of this size! E. S. 



The house will require three 2i^-inch 

 flow pipes and eighteen 2-inch returns. 

 One flow pipe can be supported on each 

 of the side walls and the other from 

 the ridge. Five or six of the return 

 pipes can be carried on each wall and
