The Weekly Florists' Review*

Is Your Whole Heating Plant Ready To Pire 



Up At Short Notice ? 



Boiler tight ? All the grates sound ? No boiler parts lost or broken? 

 All pipe connections tight, and pipes fastened up securely ? 



Better drop us a line at once and we'll come and look over 

 the whole system, and put in whatever is necessary, or send it to 

 you and let you do it. Whichever way, get after it now — It will 

 save a lot of worry and needless hurry expenses when the first 

 cold spell hits your greenhouses.

(ireeohoase Heating. 



If subscribers will state clearly the de- 

 tails of their heating problems, the Ee- 

 viEW will give in this column the opinion 

 of a man thoroughly familiar with the 

 practical side of greenhouse heating. 



Growers will appreciate their interest 

 in the subject of railroad freight rates 

 when they stop to consider that many of 

 them are paying in freight twice what 

 the coal is worth at the mouth of the 

 mine. 



A GROWER whose stock did not produce 

 as it should invested in a recording 

 thermometer and said nothing to his 

 night man, whereupon the reason for 

 poor results became plainly apparent. 

 When introduced to the iron box with 

 the clock in it the average night man, 

 instead of becoming angry because he is 

 being watched, is pleased that he now 

 has the chance of showing what a really 

 good man he is, and proceeds to make 

 the machine mark a perfectly straight 

 line during the hours he is on duty. 



A RANGE OF FIVE HOUSES. 



I am figuring on heating a plant with 

 a hot water boiler. I have two houses 

 running north and south, 23x126. How 

 many 2i/>-inch flows and how many l^A- 

 inch returns will be needed for each of 

 these houses, one of them for roses and 

 the other for carnations? 



I have two more houses, 23x100, run- 

 ning east and west. In these I expect 

 to grow lettuce, in solid beds twenty feet 

 wide. The boiler is about twenty feet 

 away from these two houses. How much 

 piping will be necessary to keep these 

 houses at 50 degrees at 10 degrees below 

 zero? There is also a small house, 16x50, 

 at the north side of these. J. P. M. 



In order to maintain a temperature of 

 60 degrees for the rose house, it will be 

 necessary to provide about 1,200 square 

 feet of radiating surface. This will re- 

 quire three 2%-inch flow pipes and fif- 

 teen 11/^ -inch returns. For a tempera- 

 ture of 50 to 55 degrees in a carnation 

 house, three 2 ^^ -inch flows and eleven 

 li/^-inch returns will be needed. 



The lettuce houses can be carried at a

somewhat lower temperature. For those 

 that are twenty-three feet wide, three 

 flows and ten returns will answer. In 

 the house 16x50 feet, one flow and seven 

 returns can be used. 



PIPING IN EASTEBN NEW YORK. 



I have two greenhouses, running north- 

 east and southwest. One house is 13x25 

 and the other 25x120. The side walls 

 measure five feet six inches to the eaves, 

 with two feet of glass in the southeast 

 wall, but no glass in the other side. The 

 gables are fourteen feet high. The boiler- 

 pit, six feet deep, is at the end of the 

 small house. I should like to get direc- 

 tions for piping these houses for hot 

 water. D. R.
