SIZE OF PIPE. 



Please let us know if ^^inch and 2- 

 inch pipe can be used for steam heating. 

 We now have hot water under pressure 

 but, as we cannot get the required tem- 

 perature, we would Uke to change it to 

 steam, if possible, with the same pipes. 

 Of course, we will have to get another 

 boiler. The one we have now is a coil 

 boiler, a regular coal eater. "We intend 

 to rebuild next spring, two houses 18x60, 

 and change the system also. 



J. J. V. 



While 4-inch pipe is only used in 

 steam heating as a main or flow pipe in 

 large establishments, there is, so far as 

 I know, no decided objection to its use 

 for other purposes. If the 4-inch pipe 

 which you have is cast-iron pipe it can- 

 not be used for steam heating, as the 

 joints cannot be made to stand the ex- 

 pansion and contraction of this form of 

 heating as usually arranged. If the pipe 

 is wrought iron, threaded, it will be sat- 

 isfactory for use with steam. 



The reason that large pipes are not 

 more frequently used for radiating pur- 

 poses in greenhouse heating is that the 

 cost per unit of radiation in large pipe 

 is much greater than in i small. A 4-inch 

 pipe gives 1.17 square feet of radiation 

 for each foot of length, while 1^4 -inch 

 pipe gives .49 of one square foot for 

 each foot of length. The 4-inch, there- 

 fore, gives only about two and one-half 

 times as much radiation per running foot 

 as does the lV4-inch pipe, yet tbe 4-inch 

 costs about five times as much per foot. 

 Badiation in 4-inch pipe would, there- 

 fore, cost about twice as much as in 

 1^4 -inch pipe. Not only that, but the 

 labor and expense of installing the small 

 pipe is only a fraction of what it is 

 with the large. 



If you have a quantity of 4-inch pipe 

 it would be economy to dispose of it and 

 buy 1*4 -inch pipe if anything like its 

 value can be obtained. The . same re- 

 marks apply to the 2-inch pipe, but to a 

 less degree. In a plant the size of - the 

 one mentioned heated with steam there 

 should be no occasion to use 4-inch pipe; 

 2-inch will be ample for all mains. 



Please discontinue my advertise* 

 ment of geraniums, as the plants are all 

 sold; am highly pleased with results. — ^A.
