Greenhouse 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. 



TWO BOILERS INSTEAD OF ONE. 



Will you please tell me what boiler 

 capacity is needed for my greenhouses, 

 which contain about 20,000 square feet 

 of glass? I have been heating them 

 with a 100-horsepower boiler, but I am 

 taking it out and wish to install two 

 boilers in its place. We seldom have 

 outside temperatures lower than zero. 



A. L.— Mo. 



Notliing is said regarding the tem- 

 perature desired in the houses, but for 

 an average of 60 degrees we would not 

 consider it necessary to have more boiler 

 capacity than fifty horsepower. How- 

 ever, we would not advise putting in 

 two boilers of twenty-five horsepower 

 each, since one of the boilers would 

 hardly be able to handle the radiation 

 except in comparatively mild weather. 

 With two boilers of thirty to thirty-five 

 horsepower each, it will be possible to 

 hold one of tliem in reserve, and with 

 the otlicr licat the houses to 60 degrees 

 except in the coldest weatlier. In fact, 

 if one boiler gets out of commission a 

 satisfactory temperature can be main- 

 tained witli tlie otlier, by a little extra 

 attention to firing. 



SIZE OF SMOKESTACK. 



I ;uii l)uil(liiig two greenliouscs, each 

 21^^x108, witli eaves seven feet high, 

 and 1 am installing a No. 2 Kroescliell 

 hot water boiler, set in a pit four feet 

 deep. Will you kindly tell me what 

 size of chin;noy I ought to erect? 

 Please state the lieight and width, giv- 

 ing both inside and outside diameter. 

 Would a chiiniiey of concrete blocks 

 be as satisfactory as a brick one? 

 There are no high buildings in the 

 immeiliate \icinity. W. B. l3. — Wis. 



Tlie size and lieight of a chimney 

 should dcji'^nd, of course, upon tlie area 

 of the <irate and the amount and ar- 

 rangement of the fire surface, whicli in 

 turn should be governed by the amount 

 of glass to be heated and the tempera- 

 ture desired in the houses. 



For greenhouses of tlie size men- 

 tioned, with not over thirty inches of 

 glass ill each of tlie side walls, to give 

 a temperature of 60 degrees when the 

 temperature is 20 degrees below zero 

 outside, we would use a hot water 

 heater rated for l,2.")tl to 1,500 square 

 feet of radiation, and this would, in 

 most styles, require a 10-incli smoke 



HEATING AND COOLING SYSTEMS 



Heating and Cooling are two branches of engineering on which we 

 specialize for the florist trade. 



Over thirty years have been devoted by us to the construction and de- 

 signing of boilers and refrigerating apparatus. 



During this period we have furnished and installed heating and cool- 

 ing systems for many of the most successful greenhouse men in this 

 country. 



The Boiler shown at left is designed for 

 steam plants lOO h. p. or less. 



For steam plants over lOO h. p. use the 



high pressure Kroeschetl, capacity 



lOO h. p. to 400 h. p. 



The Kroeschell Water Tube Steam Boiler 



NO MASONRY-NO TUBES TO CLEAN 



We manufacture every type of boiler from the smallest house heater to the 

 largest 600 h. p. steam unit. 



When you are in need of a boiler for your greenhouses, use one of the follow- 

 ing; they are best suited for greenhouse heating: 



The Kroeschell Hot Water Boiler. 

 The Kroeschell Tubeless Boiler. 



The Kroeschell Water Tube Steam Boiler. 

 The Kroeschell High Pressure Steam Boiler 



The Famous Kroeschell Hot Water Boiler 

 Made in twenty-two sizes. 



We call your attention to the Kroeschell System of Refrigeration installed 

 by us recently for the following greenhouse concerns. The high efficiency and low 

 cost of operation place the Kroeschell system in the foremost rank for florists' use.
