CreenhoBse Heating. 



Subscribers 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. 



FOUR-INCH FLUES FOR PIPING. 



Will you please tell me how to pipe 

 my greenhouse, which is 20x50 feet? 

 It has three feet of boards and sixteen 

 inches of glass in each side wall. The 

 north end is protected by an office and 

 boiler shed. A temperature of 50 de- 

 grees is to be maintained when the out- 

 side temperature is 15 degrees below 

 zero. Would 4-inch boiler flues be sat- 

 isfactory as piping for this house? 



H. M. G.— Ohio. 



While the house can be heated by 

 using two 4-inch boiler flues as flows 

 under each of the side benches, with an 

 equal number of returns, making eight 

 4-inch flues in all, I would prefer to use 

 ten 3-inch flues, and even better re- 

 sults may be obtained by using a still 

 smaller size. To distribute the heat 

 evenly through the house, I would pre- 

 fer to use a 2-inch wrought-iron flow 

 pipe upon each plate and another about 

 two feet below the ridge. With these 

 connect nine 2-inch returns, arranged 

 in three coils of three pipes each, either 

 on the walls or under the benches. Three 

 2^.-inch flows and ten li/j-inch returns 

 would also give good results. 



QUESTION IS NOT QUITE CLEAR. 



Please inform us how much piping to 

 use, and how to arrange it, to heat a 

 greenhouse 20x125. The height of the 

 house is about fifteen feet from ground 

 to ridge. It runs east and west and 

 has no glass in the north wall. We 

 have a 12-hor8epower boiler, which we 

 intend to locate at the east end of 

 the house. We wish to use li/>-inch 

 pipe and to maintain a temperature of 

 <50 degrees. The lowest outside tempera- 

 ture is about 20 degrees below zero. Is 

 it necessary to have heat under the 

 benches, or will it be just as satisfac- 

 tory to have the pipes run along the 

 walls? The house will be divided into 

 two parts, one for carnations and the 

 other for potted plants. 



E. M. & S.— 111. 



While the statements regarding the 

 house to be heated are clear and com- 

 plete in most respects, in two important 

 points the data are deficient and hence 

 it is not possible to give as definite a 

 reply as would be desirable. I am not 

 able to determine whether steam or hot 

 water will be used for heating the 

 house. The size of pipe mentioned, 

 which is the only clue, is rather large

The Kroeschell 



is making the most 

 wonderful greenhouse 

 heating record in the 

 world. Florists who 

 have used other makes 

 are constantly giving 

 the Kroeschell the 

 highest praise. 



10,788,000 SQ. ft. 

 of glass was eauipped 

 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. 



Florists in every State are usioK (lie Kroeschell Boiler, and 

 mighty is their praise. The year of 1914 brought an enormous 

 number of new customers who saw our boiler in operation 

 at other places. We attribute the large sales of this season to 

 the good work the Kroeschell Boiler la doing everywhere. 



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

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

A FAMOUS LONG ISLAND ESTABLISHMENT 



During the last cold wave, 6 above zero with a 90-mile gale blowing, 

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

 speaks well for your heating plan. 



There are no 'remarks or suggestions to make regarding your boilers, 

 ns we consider same the acme of perfection for greenhouse hot water beating 

 in every way. 



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

 ing purposes is certainly a "GEM." An easier, more effective as well as 

 economical boiler as to fuel consumption I have not seen.
