RADIATION. 



Will you inform me as to how many 

 feet of radiation a 1-inch, 1^-inch, 1%- 

 inch, 2-inch, 2yo-inch, 3-inch, 3y2-inch 

 and 4-inch pipe ought to supply, using 

 hot water? F. M. L. 



Pipes less than li^-inch are seldom 

 used as flow pipes or risers. The follow- 

 ing table will show the amount of radia- 

 tion a given size pipe will supply : 



" 1%-lnch pipe, 225 square feet radiation. 



2 -Inch pipe, 400 square feet radiation. 

 2^-lnch pipe, 620 square feet radiation. 



3 -Inch pipe, 900 square feet radiation. 

 3^-lnch pipe, 1,220 square feet radiation. 



4 -Inch pipe, 1,660 square feet radiation. 



The above table is on a hot water 

 basis. ^L. C. C. 



CONVERTIBLE SYSTEM. 



I have heard of changing from hot 

 water to steam by simply taking out a 

 part of the piping. Is it practicable to 

 heat by steam through 2-inch pipes? 

 My flows are 2-inch and 2 1/^ -inch and re- 

 turn 2-inch. The longest run, from the 

 boiler through the house and back to the 

 boiler, is 250 feet. F. W. F. 



Yes, it is perfectly practicable to 

 change from hot water to steam by re- 

 ducing the amount of piping; in fact, 

 many greenhouse plants are now being 

 constructed on a Convertible basis; i. e., 

 so as to use hot water during spring and 

 fall, while a mild heat is required, and 

 then, when severe weather sets in, to 

 draw off the water, close the valve to 

 the expansion tank and run the plant on 

 a steam basis. Two-inch pipe is not the 

 ideal for this plan, however, although it 

 is a satisfactory size for hot water and 

 can be used for steam. If you have suf- 

 ficient radiation for mild weather and 

 can work the plant on a convertible basis, 

 place a few gate valves in the system, so 

 as to cut out enough radiation to allow 

 working it on a steam basis. It would 

 be well to have the present radiation 

 figured up and the changes necessary ac- 

 curately determined before removing any 

 piping. L. C. C. 



HOT WATER OR STEAM. 



I wish to know which will be the 

 cheaper, to heat with soft coal and hot 

 water or with hard coal and steam. 

 Which will bring the best results in a 

 rose house? Can you give the names of 

 two of the best boilers, one for hot water 

 and one for steam? M. E. A. 



It is impossible to decide your question 

 without full information in regard to 

 local conditions. I know you are in a 

 soft-coal region and that soft coal or 

 coke are available. The size of the plant

to be heated, as well as the character of 

 the crops grown are important considera- 

 tions to be taken account of in making a 

 choice between hot water and steam. 

 As a general proposition, however, water 

 is more satisfactory for small plants, 

 say two or three houses 100 feet long, 

 while steam is cheaper to install and 

 more satisfactory for extensive plants. 

 Hot water with hard coal costs less to 

 manage, while steam with soft coal is 

 dearer as regards time of fireman, but 

 more satisfactory for extensive plants. 

 There are many good greenhouse boilers 

 on the market, both steel and cast iron. 

 Get the one with greatest surface for 

 the heated gases to come in contact with.

PIPE FOR HEATING. 



My new east and west house is 20x31. 

 The side walls are four feet high and 

 nine feet to the ridge. It has two feet 

 of glass on the south side, both sides 

 being exposed and both ends protected. 

 The outside temperature sometimes drops 

 to 25 degrees below zero. I wish to 

 maintain a temperature of 58 to 60 de- 

 grees. What size pipe should I use and 

 how arrange for hot water? 



I also have one house 20x24, nine feet 

 to the ridge, walls four-feet, built on the
