(ireenhoasi Heating. 



DO IT NOW. 



' ' A stitch in time saves nine, ' ' or even 

 ten, if it is in a greenhouse heating plant. 



In the last few years there has been 

 great improvement in the character of 

 the heating apparatus used by florists, for 

 it has come to be realized that the facili- 

 ties for warming are about the most im- 

 portant subject the grower has to consider. 

 In these days of close competition it may 

 easily happen that the efficiency of the 

 heating apparatus may spell loss or profit : 

 Without enough heat, properly distrib- 

 uted and controlled, the stock will not be 

 of its best quality; and the difference in 

 fuel consumed as between an economical 

 arrangement and an extravagant one will 

 eat a big hole in the receipts. 



It is a far cry from the primitive flue 

 to the up-to-date systems now used in the 

 big, modern plants, like that of W. H. 

 Elliott, who circulates steam by gravity 

 through a half mile of pipe, or the Craig 

 Co., who will heat a big new range with 

 hot water under forced circulation. The 

 big growers employ experts to plan the 

 heating arrangements and consider the 

 service so valuable that they are not only 

 willing to pay well for advice but expend 

 large sums in following it. To the small 

 grower the subject is of no less impor- 

 tance. 



This is the season at which the appa- 

 ratus should be overhauled from A to Z 

 and put in apple-pie order. Changes, if 

 needed, take time and the cool nights, 

 with their need for heat, will be here 

 almost before you know it. 



Hot water not only remains the best 

 medium for warming, under certain con- 

 ditions, but its range has been greatly 

 extended in the last few years and it is 

 now employed satisfactorily and econom- 

 ically in much larger units than hereto- 

 fore. Steam has been so developed, as 

 applied to greenhouse heating, that many 

 of the largest growers have found it a 

 profitable investment to concentrate the 

 entire boiler plant in one central station, 

 which may include pumps, dynamos and 

 even cold storage apparatus. 



While the best heating apparatus, small 

 or large, is the one with the fewest frills, 

 it is not always possible to employ either 

 water or steam in its simplest form ; con- 

 ditions in each case nui.st be met, and

almost always can be satisfactorily met by 

 study. It is not possible to say that any 

 one system is the best under all circum- 

 stances and it may require, and, indeed, 

 in possibly the majority of cases does re- 

 quire, the addition of one or more of the 

 mechanical aids to secure the right re- 

 sults. Especially are these needed in the 

 numerous establishments that have grown 

 from small beginnings without plan or 

 other reason than the need for "another 

 house" to care for increasing business. 



Nowadays there are half a dozen ways 

 of making hot water do things it would 

 not do before the inventors got to work. 

 And steam is assisted on its rounds by 

 regulators, condensation traps and me- 

 chanically created vacuums. Even pipe 

 joints at trifling cost may be made tight 

 with the guarantee that they will not rust 

 and become inseparable. 



By all means go over your heating ap- 

 paratus now. Study its defects and rec- 

 tify them; if not by such simple changes 

 as frequently accomplish the desired re- 

 sult, then by employing one or more of 

 the devices which are needed to make the 

 apparatus both efficient and economical. 

 Money spent in this way frequently comes 

 back quickly; growers using small coal 

 found a rocking grate with closely spaced 

 bars quickly paid for itself through the 

 saving of fuel that had dropped through 

 their old, wide bars.

 16x24. The boarding will be double 

 thick. The south wall is four feet high, 

 with two feet of glass. The house is 

 built with the long span to the 80uth. 

 The house rifns east and west, to connect 

 with another house at the west end, with 

 a glass partition where it connects. How 

 many runs of pipe will it taket What 

 size would you advise using: 1^4 inch or 

 2-inch? The boiler is located in the cel- 

 lar of the dwelling. The temperature re- 

 quired will be for carnations, say from 

 50 to 60 degrees, in Massachusetts cli- 

 mate. L. W. 



The house can be heato<l with hot 

 water by installing the following pipe: 

 One 2Vj-inch or 3-inch flow from the 

 boiler to the far end of the house, there 

 to divide and return by fifteen 2-inch 

 pipes. I would not advise the use of 

 114 -inch pipe for hot water unless you 

 intend converting the plant into a steam 

 plant some day. If so. install twenty-one 

 11/4 -inch pipes as returns.
