direenhouse Heating. 



SuBSCBiBEBS are invited to write the 

 Editor of this Department with regard to 

 any details of greenhouse heating that 

 are not understood. But please do not 

 ask The Review to make a choice of ap- 

 paratus for you. The greenhouse heating 

 equipment advertised in this paper is, we 

 believe, the best for the trade to buy, 

 and each article the best in the special 

 field of its adaptation. 



WHY THE LACK OF HEAT? 



I have one greenhouse, 20x50. One 

 end is attached to a shed. The side 

 walls are six feet high to the gutters 

 and the front is glass. The height to 

 the ridge is thirteen feet. I have a 

 1,600-foot, hot water. No. 2 Kewanee 

 boiler. Two 2-inch mains rise directly 

 from the boiler, slope to the far end 

 of the greenhouse and empty into six 

 2-inch coils on each side of the house. 

 These return the water by natural 

 gravity to the boiler. 



The circulation seems to be good, as 

 in thirty minutes I can have the water 

 boiling in the returns, but I have not 

 succeeded in carrying a temperature of 

 more than 40 degrees in zero weather. 

 Would a circulator cause sufficient im- 

 provement so that I could carry 50 de- 

 fees, or should I put in more pipes? 

 grew vegetables last winter, but in- 

 tend to grow more flowers this year 

 and should like to maintain 50 to 60 

 degrees of heat. I am planning to put 

 in two benches; would you advise put- 

 ting pipes under themf 



F. E. P.— Ind. 



As I understand the statement, the 

 house has no glass in the side walls 

 and can only be heated to 40 degrees, 

 although there are two 2-inch flows and 

 twelve 2-inch returns and the water in 

 the returns is boiling. 



With the amount of radiation men- 

 tioned, there should be no difficulty in 

 maintaining a temperature of 60 de- 

 grees in zero weather if the water in 

 the returns is at 160 degrees. The 

 boiler is two or three times as large 

 as is needed, and the boiling of the 

 water may result in retarding the cir- 

 culation. This, of course, may be cor- 

 rected by attaching a mercury genera- 

 tor. There is ample radiation, but, un- 

 less the generator is used, it will be 

 advisable to use one of the returns 

 in each coil as a flow pipe. Each of 

 the flow pipes should be connected with 

 the expansion tank. A part of the 

 pipes, at least, should be under the 

 benches. __^ 



TO HEAT HOUSE AND LEAN-TO. 



We have just completed a green- 

 house 20x60, with walls four feet six 

 inches high of wood. In the south end 

 the glass runs to within three feet of 

 ^e ground. The gable is eleven feet 

 high. We wish to grow lettuce and 

 carnations. In this section the tem- 

 perature seldom goes to zero, but ouce

"Kegarding the Eroeschell. it is the best vre have ever had and satis- 

 factory beyond our expectations. It heats up especially quick and hs^ saved 

 us considerable already in the price of fuel. When we are in need of another 

 boiler, we will give the Eroeschell the first consideration." 



(Signed) WM. W. EDGAB CO.. Waverley, Mass. 



The KROESCHELL has replaced hundreds of cast iron boilers. 

 In every case higher temperatures are secured with the KROE- 

 SCHELL with the same piping and with less fuel. 



The KROESCHELL is making the most wonderful gi*eenhouse 

 heating record in the world. Our boilers were installed to heat 

 2,304,450 sq. ft. glass in 1914. Florists who have used other 

 makes are constantly giving the KROESCHELL the highest praise. 



THAT CONTENTED EEELING 



When the KROESCHELL is on duty, your mind is at ease. The 

 longer you have it the more you believe in it. THE KROE- 

 SCHELL IS ITS OWN BEST REASON.
