Th^Weefcly Forists' Review.

Qreenhoflse Beating. 



The Kroeschell Bros. Co., Chicago, is 

 preparing to put on the market a new 

 size of «S W«ll-known hot water boiler. 

 They call it the Jumbo, because it is 

 built to heAt 50,000 feet of glass to 60 

 degrees wheil it is 15 degrees below zero 

 outside. 



HEATING TWO HOUSES. 



We wish to kn»w how many flows and 

 returns it will take to heat the follow- 

 ing houses:* No. 1, a north and south 

 house, 18x98, and ten feet to the ridge; 

 the side waJls four and one-half feet 

 high, glass ventilatord in the east wall 

 and a greenhouse on the west side. No. 

 2, an east and west house, 24x105, and 

 twelve feet to the ridge; side walls four 

 and one-half feet high, glass ventilators 

 in the south wall; the north wall has 

 no protection. The houses have a fall of 

 eighteen iifches from the end to the 

 boiler-pit. The boiler is two feet lower 

 than the lowest part of either house. We 

 have a lot of 2-inch pipe and would like 

 to use that if possible. We have 4-inch 

 flows and returns attached to the boiler. 

 Hot water is used. We wish to maintain 

 a temperature of 60 degrees when it is 

 10 degrees below zero. B. F. Co. 



To heat house No. 1 by the use of 

 2-inch pipe, twelve runs of pipe should 

 be installed. This can be supplied by 

 using a single 3-inch flow pipe or two 

 lines of the twelve can be used as flow 

 pipes, the remaining ten serving in two 

 coils of five each as returns. House No. 

 2 can be heated by the use of 2-inch 

 pipe if sixteen lines are installed. If a 

 single riser is desired a 3% -inch pipe 

 will be necessary. If 2-inch risers are 

 employed, three will be necessary. The 

 remaining thirteen pipes can be divided 

 into three coils, thus throwing the extra 

 pipe into the coil on the most exposed 

 side of the house. L. C. C. 



PIPING TWO HOUSES. 



I have two east and west houses, each 

 22%xl50 and ten feet to the ridge, with 

 cement walls and sixteen inches of glass 

 on each wall. Temperature outdoors has 

 dropped to 30 degrees below zero. The 

 north house is for carnations and sixty 

 feet of the south house is used for roses, 

 forty feet for ferns and fifty feet for 

 bedding plants. The boiler-room is at 

 the northwest corner of the carnation 

 house, and the sixty horse-power steam 

 boiler is set two and one-half feet be- 

 low the lowest heating coil. I have a 

 large boiler because I expect to add 

 more houses. My feed pipe is 3-inch and 

 return 2-inch. Can I use a reducing 

 valve on the feed and a check-valve on 

 the return with good results? I am 

 rather short on 1^-inch pipe, but have 

 plenty of 2-inch. Can I use the latter 

 with good results t How much less would 

 it take? E. K. B. 



To heat the house 221/^x150 with steam 

 by the use of 2-inch pipe, the house 

 should be provided with a 3-inch flow 

 under the ridge and twelve 2-ineh re- 

 turns, or eighteen IJ^-inch returns. The 

 main return is a little small to supply 

 the two houses. A 4-inch main riser would 

 be better, unless you carry an independ- 

 ent 3-inch flow from the boiler to each 

 house. You can use reducing valves on

Oentlehen:— You can strongly and unhesitatinrly recommend the 

 " Eclipse " piston type reducing valve to florists. We have two purchased 

 of you last year. We would not have them out for double their cost and 

 find them as sensitive as a watch. We will be in Chicaero soon to take up 

 the vscuum system with you. Yours truly,
