The Florists' Review 



AUGDST 1, 1912. 



is to be used, run one 4-inch pipe to 

 the greenhouse and take off a 2% -inch 

 flow to run along the plate. Then, by 

 means of an eighth bend, extend the 

 flow pipe to a point under the ridge and 

 then, make a square turn to the east. 

 Take off a 2^ -inch flow to be carried 

 down to the plate on the south side and 

 extend the main under the ridge to 

 the east end of the house, after reduc- 

 ing to 2% -inch. Just before reaching 

 the partition, take off a 2-inch flow 

 from each of the flows on the plates, 

 to be dropped down to feed a coil of 

 six 2-inch pipes, which will be required 

 to supplement the radiation coming 

 from the other house in order to raise 

 the temperature to 70 degrees. 



There will then be three 2 ^-inch flow 

 pipes passing through the house to the 

 extreme east end. In addition to these 

 pipes, it will require eighteen 2-inch 

 pipes to maintain a temperature of 60 

 degrees in zero weather. Six of these 

 should fee fed from each main. Those 

 connected with the flow pipe on the 

 plates should be on the walls under- 

 neath and the others can be under the 

 two middle benches. When the parti- 

 tion is reached, the returns in the mid- 

 dle of the house should be united into 

 one 2%-inch return. This should be 

 carried back to the point where the 

 -4)ipe8 enter the house, either through 

 the west room or under the walk and 

 along the north wall, as will be most 

 convenient, and there connected with 

 the main return. The other returns 

 should also be united at the west end 

 of the greenhouse and connected with 

 the main return. 



A NORTH DAKOTA OREENHOXJSE. 



I am building a greenhouse, 20x115, 

 four feet high to the eaves and twelve 

 feet to the ridge. How many pipes and 

 what size should I usef State the 

 size of the supply and returns for steam. 

 I wish a temperature of 50 degrees at 

 night. The outside temperature in this 

 part of North Dakota occasionally drops 

 to 40 degrees below zero. I can get a 

 small steel boiler, upright, with nine 

 square feet of grate surface. Will tBis 

 be large enough to heat the house f 



M. B. 



Judging from the size of the grate, 

 the boiler described is amply large 

 to heat the greenhouse. For heating 

 pipes, use one 2-inch overhead main 

 and nine 1%-inch returns. Three of 

 the returns can be upon each wall and 

 the others under the middle bench. 



YOKING TWO BOILEKS. 



I have two cast-iron steam boilers. 

 One is a round boiler, with a grate 

 twenty-eight inches in diameter, and is 

 rated at 700 square feet of radiation. 

 The other is a sectional boiler, with 

 grates 28x43 inches, and is rated at 

 1,700 feet of radiation. Will the two 

 boilers heat my two greenhouses to 40 

 degrees in this Massachusetts climate! 

 One house is 30x200 and five and one- 

 half feet to the plate, with three feet 

 of glass in the south wall. The other 

 house is 40x135 and six feet to the 

 plate, With two feet of glass in the 

 north and four feet of glass in the 

 south wall. I shall use a gravity, low 

 pressure system, with the returns thred 

 feet above the boilers. How large a 

 supply pipe do I need for the 135-foot 

 house f I want to extend the house to

WHICH SHALL IT BE? 



CAST IRON BOILERS-FOOL ECONOMY (false ratings, fuel 

 waste, danger of breakdowns, dealers' profits), OR 



KROESCHELL BOILERS-FUEL ECONOMY (honest ratings, 

 safety, quick heat, no boiler pita, no dealers' profits)?

Banffe of Adun Lanb & Son, HnghsonTille, K. T. Their letter tpeakt for itself. 



We purchased of you this spring a No. 6 Kroeschell Boiler, which yon guaranteed would 

 take the place of three caat iron boilera. Well, the whole thing In a nutshell Is thl»— your 

 word is as good as gold. Night before last we had a severe 

 storm of snow and sleet and a very high wind; we had not the 

 least bit of trouble. We fired the last at 10 p. m. Nov. 24, and » - - . - 



the next morning at 7:00 o'clock we looked at the houses and /g V) yf 



found It only 1 degree less than when we fired the last coal, 

 9 hours earlier. If this isn't magnificent work and a good test, 

 we would be pleased to hear from anyone else that could furnish 

 a better boiler. 



We know if parties wishing a boiler would 

 get one from you they never would try any 

 other. We think in five years' running of 

 this boiler we will have the price saved in 

 the difference in our coal bill. 



Wishing you the best of 

 success, we remain, 

 Very truly yours, 

 Adam Laub & Son, 

 Hughsonville, N. Y.
