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 Beview to make a choice of ap- 

 paratus for you. The greenhouse heating 

 equipment advertised in this par)er is, we 

 believe, the best for the trad^ ^o buy, 

 and each article the best in the special 

 field of its adaptation.

Will you kindly give me a little ad- 

 vice on the piping of my new green- 

 house for hot water! The enclosed 

 sketch shows the greenhouse and also 

 my residence, in the basement of which 

 the boiler is located. The basement is 

 four feet below the level of the green- 

 house floor. I intend to run a S^^-inch 

 or 4-inch pipe from the boiler to the 

 center of the greenhouse, over the 

 benches. From this main I would run 

 five 2-inch flow pipes to the other end 

 of the house, drop them down under the 

 benches and connect five li4-inch pipes 

 with each flow, thus having five return 

 pipes under each bench, or twenty-five 

 1^-inch pipes in all. Do you think this 

 is the right way to pipe the house? I 

 expect to grow carnations, pot plants 

 and some vegetables. H. 0. — N. D. 



The sketch shows the greenhouse to 

 be 25x100, with 3-foot walls of cement 

 blocks and apparently about the same 

 amount of glass wall above the concrete. 

 There are five raised benches, from 

 three to five feet in width. The boiler 

 house is located at the northeast corner 

 of the greenhouse. 



In an open hot water system we pre- 

 fer to use 21^-inch flow pipes and 2-inch 

 returns, in a house of this size. Unless 

 the boiler is ten feet below the returns, 

 we would not care to use l^/i-inch re- 

 turns in a house 100 feet in length, ex- 

 cept when it is run under pressure. 



The amount of radiation suggested in 

 the inquiry is fully fifty per cent more 

 than is needed for a temperature of 50 

 degrees, which will answer as a mini- 

 mum temperature for lettuce, and three 

 pipes in each coil will be sufiBcient with 

 a closed system. For an open system, 

 with the top of the boiler a foot or 

 so below the returns, we would use three 

 2%-inch flow pipes, running one on each 

 purlin or at a point about halfway from 

 the plate to the ridge, and the other two 

 or three feet below the ridge. At the 

 farther end of the house drop down 

 each of the flow pipes to a point a foot

 Gentlemen:— 



Now that the firing season is over, and after a long cold winter, the 

 coldest night being 6" below zero, I want to say I am well pleased with 

 the No. 46 Water Tube Steam Boiler and the No. 14 Hot Water Boiler. 

 They are doing all you claim for them and more. The No. 14 Hot Water 

 Boiler is heating that large house to 60^ with the greatest ease in zero 

 weather without the help of the steam boiler. 



Tliia steam boiler I think Is a ^ronder, a Quick steamer, and 

 holds the steam, the easiest boiler in the world to clean and to keep 

 clean. The double steam trap system is working fine, keeping all the 

 steam lines well drained. 



The boiler tube hot water system is the winner, the rapid circulation 

 and even temperature obtained from this system is wonderful. 



After being told repeatedly by other growers that roses could not be 

 grown with hot water heat, we are getting the best kind of results, not 

 only from the heating systems and boilers, but also from the roses. 



Yours very truly, 



(Signed) W, J. PILCHER.

Gentlemen:— 



I wish to report that I have use'd my No. 49 Kroesotaell Water 

 Tube Steam Boiler for the past two seasons, and will say I could not 

 compare it with my former boiler, as it is so far superior in every way 

 that there is no comparison whatever. 



It does the work of two tubular steam boilers- saves fuel, needs less 

 attention, as the fire lasts much longer— is easily cleaned, there being no 

 flues to clean every night, as was the case with the old boilers. 



If I should need another boiler, I would not think of buying any other 

 kind. Yours very truly, 



(Signed) S. E. MUNTZ. 



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. 



12,468,220 SQ. ft. 

 of glass was eauipped 

 with the Krceschell 

 Boiler during the past 

 five years. 



The KroescheD 



is used by hundreds 

 of Florists' Review 

 readers and mighty is 

 their praise. The year 

 of 1915 brought an 

 enormous number of 

 new customers who 

 saw our boiltrs in 

 operation at othar 

 places. We attribute 

 the largt sales of this 

 season to tha good 

 work the Kroeschell 

 Bailer is doing every- 

 where.
