The Florists' Review 



June 29. 1922 



under the flow jiipes in the coils. Each 

 of the four coils consists of three re- 

 turns, except the one (in the exposed 

 wall, which has four pipes. As we un- 

 derstand it, the chanjfcs pro])osed will 

 consist of arranging the coils liorizon- 

 tally (all of the ])i]ies side by side at 

 the same level) insteail of in vertical 

 coils, as at ])resent. There is little to be 

 gained by tliis change and, in fact, ver- 

 tical coils for the side walls would be 

 preferable, tliese being less in the way. 



Another change is in taking out the 

 four 2-inch returns and substituting 

 one main 4-inch flow overhe;id in the 

 middle of tlie house, with .'i-inch ]ii])es 

 to conne<-t it with the coils at the farther 

 end of the house. This will change the 

 four coils from flows to retui'us and, 

 unless they now run uphill from the 

 boiler, it will be necessary to change 

 the grade so that as returns they will 

 run downhill. 



Es])ecially if the boiler pit is only 

 one foot lu'low the floor of the green- 

 house, we think it advisable to ele- 

 vate the l>ilies, aiul particularly the 

 flows, as much as ])OssiljJe. To heat the 

 house described to ol) degree's in zero 

 weather will re(juire over ],r)0() square 

 feet of radiation aiul this is rather more 

 than can be handled to advantage by a 

 4-incli main. We should ]irefer to use 

 five L"-j-iiich flow pipes and connect the 

 flows at the farther end of the house 

 with five coils, each containing fixe 

 2 inch pipes. 



It is noteil that the owner of the 

 house lives in San Francisco. If the 

 house is located near that city, there 

 would be no iiecessityfor planning radia, 

 tion for zero weather, as is stated 

 on the sketch, and in that case it is 

 ])robal)le that four 2i/i-inch flow pil>es, 

 connected with four coils, each con- 

 taining three 2-inch returns, would be 

 aiiii)le. The flows as well as the I'eturns 

 should run downhill. One reason for 

 using the five 2i/;-iiicli instead of one 

 4-inch l)ipe for the flows is that the 

 water in small pipes will cool faster 

 than in a large one and this will tend 

 to improve the circulation. In case the 

 flow j)ipes run u])hill, large i)i])es will be 

 better than small ones. 



PIPE and FLUES 



A LL SIZES of second-hand pipe, with
