Greenhouse Heating 



SuBSCBiBEBS are invited to write the 

 Editor of this Department with regard to 

 any details of greenhouse heating that 

 are not understood. When information 

 is desired regarding the capacity of boil- 

 ers, or the amount of radiation required 

 for a greenhouse, the needed temperatures 

 ehould be stated in the inquiry, as well 

 as the amount of glass in the side walls, 

 and the dimensions and general arrange- 

 ment of the greenhouses. It is often help- 

 ful, also, to have a sketch showing the 

 location of the houses. 



SEEKING HEATING EFFICIENCY. 



"How to increase the eflSlciency of 

 heating systems — to lower fuel consump- 

 tion and keep the steam-heated ma- 

 chines at uniform, maximum heat— is 

 receiving as much consideration today 

 from florists as a year ago when a coal 

 shortage existed," asserts A. Fitzger- 

 ald, general manager of the Morehead 

 Mfg. Co., of Detroit. "With the pres- 

 ent prices of fuel prevailing, florists 

 are confronted with a serious problem. 

 Their coal bills will be far above the 

 average, unless their greenhouses can 

 be heated with less fuel than was re- 

 quired in previous winters. As a result, 

 we are receiving more requests for in- 

 formation from florists than ever be- 

 fore, and when we refer them to green- 

 houses that have lowered their fuel 

 consumption fifteen to twenty per 

 cent after installing traps, orders are 

 forthcoming from practically everyone 

 who makes inquiry. 



"Florists are pretty well satisfied 

 that fuel prices will not drop and if a 

 saving can be effected, they are suf- 

 ficiently progressive to take advantage 

 of the opportunity. We expect to do 

 twice as much business with greenhouse 

 operators during the next few months 

 as during all of 1918, which was a rec- 

 ord-breaking year for us. ' ' 



BOILEB IN RESIDENCE CELLAB. 



Please give me some information in 

 regard to the heating of a small green- 

 house which i am about to build. En- 

 closed is a rough sketch which shows 

 the location and other particulars. I 

 desire to erect the greenhouse near the 

 street, as shown in the sketch, and heat 

 it from the basement of my residence. 

 The temperature required will be 55 to 

 60 degrees when the outside tempera- 

 ture is 10 degrees below zero. I have 

 hot water heat in the residence, but in- 

 tend to install a separate boiler for the 

 greenhouse. Do you think I can get 

 satisfactory results from this plan, or 

 will it be advisable to build a boiler 

 house at the north end of the green- 

 house? 



Please describe the proper arrange- 

 ment of the pipes in the greenhouse, 

 stating the size of the pipes and the 

 number required. Raised benches will 

 be used. I intend to grow vegetable 

 plants and a few flowers. The base- 

 ment is six and one-half feet deep. Will 

 it be necessary to run the flow pipe over- 

 head or will it answer if placed under- 

 ground? What size of boiler will be 

 needed, using soft coal?

The sketch shows the proposed loca- 

 Hon of the greenhouse to be directly 

 north of and about fifty feet away from

TO THE MAN WHO DOES NOT OWN A KROESCHELL-Posslbly you may have 

 wondered why KROESCHELL Boilers are not sold by any of the Greenhouse 

 Buildinc or Construction Companies. If so, we feel it is our duty to state, in 

 fairness and Justice to all concerned, that KROESCHELL Boilers are never sold 

 by anyone but KROESCHELL BROS. CO. We do not quote anyone dealing in 

 Greenhouse material or boilers, special resale prices. We have no Agents, and 

 therefore our prices are based on sales direct from Factory to user. 



Our stand in this matter has brought out a lot of rivalry; nevertheless, the great 

 efficiency of the KROESCHELL Greenhouse Boiler cannot be disputed, and in 

 spite of the increased competition, the KROESCHELL Boiler is heating more 

 glass than any other make. 



Our business (ESTABLISHED 1879) is to build boilers of all types, from the 

 smallest house heater to the largest 600 H. P. Water Tube Steam Boiler. For forty 

 years we have confined our entire efforts to the designing and construction of 

 high-grade boilers, and during this time have served the Florists' Trade of this 

 country and Foreign Countries, to the full satisfaction of every one of our customers. 



"The customer's interest first"— is the basis of the KROESCHELL standard. This 

 principle makes the KROESCHELL Policy the most liberal of all in the Green- 

 house Boiler business. The great variety of boilers that we make places us in a 

 commanding position. It is tne KROESCHELL principle to supply only the type 

 of boiler best suited for the conditions. For this reason we always furnish the 

 most efficient boiler unit in every case.
