CHANGING THE HEATING SYSTEM. 



Having decided to change the heat- 

 ing system in my greenhouse from 

 steam to hot water, I should like to get 

 some information on the subject. I 

 shall install a sectional boiler. The 

 house is 21 x 100 and has 12-foot sash- 

 bars. It has one glass gable. The sides 

 are four feet high and contain two and 

 one-half feet of glass. What should be 

 the rating of the' boiler? Could 1,000 

 feet of 1^-inch pipe, which was used 

 for steam, be used satisfactorily for hot 

 water! State the number of flows, their 

 size, and how theyr should be placed. 

 Could the pipes for the side benches be 

 placed on the walls, so as not to inter- 

 fere with raising chickens under the 

 bench? 



How many more feet of l^/^-inch pipe 

 will be necessary, besides the 1,000 feet, 

 to heat the house to a temperature of 

 50 to 60 degrees in zero weather? What 

 valves and couplings should be used and 

 where should they be placed so as to 

 make a safe, reliable system? How 

 deep should the boiler pit be? Where 

 and how should the expansion tank be 

 placed? Are hot water systems ar- 

 ranged with valves, so one part of the 

 system can be cut oflf and the other 



{>art . used, in case of breakdowns or 

 eaks? The greenhouse extends north 

 and south and the boiler room is at the 

 north end. There are two side benches 

 and two in the center. 



G. R. S.— Pa. 



For a night temperature of 60 de- 

 grees, not far from 900 square feet of 

 radiation will be required and this will 

 need a boiler with a grate having about 

 six square feet of surface, or a capacity 

 of ten horsepower. 



To heat the house, we would place a 

 2%-inch flow pipe upon each plate and 

 another three feet under the ridge. The 

 1,000 feet of 1^-inch pipe will make 

 ten returns, four of which should be 

 placed upon each wall, and the others 

 should be under one of the middle 

 benches. In addition, four 1^/4 -inch or 

 three 2-inch returns will be needed to 

 give the required radiating surface. 

 These, with the two returns already 

 mentioned, should be distributed under 

 the middle benches and connected with 

 the overhead flow pipe, while the re- 

 turns on the walls should be joined with 

 the flows located on the plates. The 

 flows should be given a fall of one inch 

 in ten to fifteen feet, or just enough to 

 keep the air from pocketing, and the 

 expansion tank should be connected

TheKroeschell 



is making the most 

 wonderful greenhouse 

 heating record in the 

 world. Florists who 

 have used other nflikes 

 are constantly giving 

 the Kroeschell the 

 highest praise. 



1S.468,S20 SQ. ft. 

 of glass was equippea 

 with the Kroeschell 

 Boiler during the past 

 five years. 



The Kroeschell 



is used by hundreds 

 of Florists' Review 

 readers and mighty is 

 their praise. The year 

 of 1916 brought an 

 enormous number of 

 new customers who 

 saw our boilers in 

 operation at other 

 places. We attribute 

 the large sales of this 

 season to the good 

 work the Kroeschell 

 Boiler is doing every- 

 where. 



With our policy—" tlie cnstomers* interest first "—perfection of constrnction 

 —factory to user prices- lionest and "true bine" boiler ratings— you simply 

 cannot lose. 



READ WHAT THE USERS SAY: 



Dubuque. Iowa. Nov. 28. 1916. 

 Gentlemen:— I wish to report that I have used my No. 45 Kroescliell 

 Watar Tuba Steam Bollar for the past two seasons, and will ^ay 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 boil- 

 ers—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. With best wishes, I remain. Yours very truly.

Walton, N. Y.. Jan. 4. 1916. 

 Gentlemen:— Your N«^7 No. 46 Water Tube Steam Boiler is the finest 

 steam boiler we have ever fired, and have fired eleven different makes before. 

 Your boiler keeps steam from 9:00 p. m. to 6:0« a. m.. without attention on zero 

 nights. Before we had three boilers and could not control temperatures so easily 

 as we can with yours. The little time consumed in cleaning same is wonder- 

 ful, and we are very well pleased. The water line is steady and it holds its 

 steam well. If we ever install another boiler, you can rest assured it will be a 

 Kroeschell. If I can be of any assistance to you in showing your boiler to 

 anyone, would be pleased to do so. or if anyone in your locality wants local 

 reference, I will gladly give same. 



Walton. N. Y.. Jan. 10. 1916. 

 Gentlemen:— Since writing you on Jan. 4th, the other morning it went down 

 to 4<' below zero, and I flted the No. 46 boiler at 11:10 p. m.: had 10 lbs. of steam 

 on with the draft half open, the houses all registering iS" to 52° and the No. 4 

 house 60''. We bricked in our boiler, so we lose no heat in the boiler room: we 

 find it a great saving. Any other information cheerfully given. 



Yours respectfully. (Signed) TRIPP FLORAL CO.
