Greenhouse Heating. 



CHICAGO FUEL MARKET. 



"There was no new business in the 

 smokeless coal trade ' ' at Chicago dur- 

 ing the last week in February, says the 

 Black Diamond, "with buying extreme- 

 ly light, contractors taking only their 

 minimum requirements and in some in- 

 stanced even less, Prices are still firm 

 at $1.40 on mine run among the bigger 

 operators, but smaller producers are ac- 

 cepting any reasonable offer. The Illi- 

 nois output is being limited to an aver- 

 age of about two days a week at the 

 mines and operators see no improve- 

 ment ahead for March. Circular prices 

 axe maintained, but no quantity of ton- 

 niage is moving. ' A few weak-kneed 

 diealers are quoting below circular and 

 have fairly well cleared up their stocks 

 by so doing, but even at that there is 

 almost no business, the bottom having 

 fallen out of the market." 



BUILDING AND PIPING. 



I am contemplating the building of 

 two greenhouses, one of them 20x100 

 and the other 25x110. They will have 

 concrete walls, eight inches thickj and 

 the side walls will be six feet high. 

 Would the houses be satisfactory with- 

 out any glass in the sides? I shall in- 

 stall an overhead system of hot water 

 heating. There is a 4-inch main pipe 

 through the shed, which is forty feet 

 long. Should there be a 5-inch main? 

 What size of flows and how many should 

 there be in each house? How many 2- 

 inch returns will be needed? The out- 

 side temperature here may drop as low 

 as 15 degrees below zero, but only for 

 jibout a week during the entire winter. 

 How deep is it necessary to dig for 

 the foundations of the concrete walls, 

 fio as to keep the walls from heaving? 

 - L. M. & S.— Nova Scotia. 



The letter does not state the temper- 

 ature desired in the houses, but for 

 about 60 degrees I would prefer to run 

 a 4-inch main flow to each of the houses 

 and would use returns of the same size. 

 This would be preferable to putting in 

 one 5-inch flow to supply both of the 

 houses. 



For the 20-foot house use three 2^2- 

 inch flow pipes and eleven 2-inch re- 

 turns for a temperature of 60 degrees, 

 while eight or nine returns would an- 

 swer for 50 degrees. For the 25-foot 

 house use three 2V^-inch flows and four-' 

 teen returns for 60 degrees and ten or 

 eleven for 50 degrees. Kun one of the 

 2%-inch flows on each plate and the 

 other about two or three feet below the 

 ridge, with about one-half of the re- 

 turns either on the side walls or under 

 the side benches, and the others dis- 

 tributed under the middle benches. 



It would be well to have at least 

 three feet of glass in each of the side 

 walls, in which case there should be an 

 additional return under each of the 

 side benches. As a rule it is not neces- 



whkN you buy-qit a kroeschell 

 the boiler of genuine erficibncy" 



Our Boilers were installed to heat 2,304,450 sq. ft. class in 1014 



The Kroeschell 



is making the most 

 wonderful greenhouse 

 heating record in the 

 world. Florists who 

 have used othermalies 

 are constantly giving 

 the Kroeschell the 

 highest praise. 



10,788,000 SQ. ft. 

 of glass was equipped 

 with the Kroeschell 

 Boiler during the past 

 five years. 



The Kroeschell 



has replaced hundreds 

 of cast iron boilers. 

 In every case higher 

 temperatures are se- 

 cured with the Kroes- 

 chell with the same 

 piping and with less 

 fuel. 



The Kroeschell is 

 sold direct from our 

 factory to users. This 

 eliminates the unnec- 

 essary greenhouse 

 builder's profit. 



Hundreds of Florists' Review readers are nsine the Kroeschell 

 Boiler, and niiehty is their praise. The year of 1914 broueht 

 an enormous number of new customers who saw our boiler in 

 operation at other places. We attribute the laree sales of this sea- 

 son to the srood work the Kroeschell Boiler is doine everywhere. 



With our policy— "the customer's interest first "—perfection of construction— factory-to- 

 user prices— honest and "true-blue" boiler ratings— you simply cannot lose.

A FAMOUS LONG ISLAND KSTABLISHMENT 



Durine the last cold wave, 6 above zero with a 90-mile eale blowinsr, 

 one end of houses was as warm as the other, no variation at all, which 

 speaks well for your heating phtn. 



There are no remarks or suKcestions to make resrardinc your boilers, 

 as we consider same the acme of perfection f«>r Kreenhouse hot water 

 heatint; in every way. 



The steam boiler you furnished us last summer for pumpine and heat- 

 inir piin)oses is certainly a "GK>I." An easier, more effective as well as 

 economical boiler as to fuel consumption I liave not seen.
