Greenhonse 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. 



PIFIKG A HOUSE 30x50. 



I am building an addition to my pres- 

 ent place, 30x50 feet. The side walls 

 are five feet in height — three feet of 

 cement and two feet of glass. The 

 house runs east and west. The west 

 end is glass and the east end is 

 connected to the office. The house is 

 an even-span one and is thirteen and 

 one-half feet to the ridge. The boiler 

 is under the office and set two feet be- 

 low the level of the greenhouse floor. 

 How many 3-inch flows shall I need 

 and where' shall I place themt I have 

 a supply of 2 and 1%-inch pipe on hand. 

 "Which is the better size for returns and 

 how many returns shall I need to main- 

 tain a temperature of 50 degrees in 

 zero weather? I want to place the re- 

 turns on the side walls and in the cen- 

 ter walk. We are located in the center 

 of a city and are well surrounded by 

 buildings. The form of heat to be 

 used is hot water. Where shall I place 

 my tank to get the best results, and 

 about how much grade do I need in 

 the piping! W. F. B. — Mass. 



In order to heat a greenhouse 30x50 

 feet, which ha« two feet of g;lass in 

 the side walls, to 50 degrees in zero 

 weather, we would use three 2%-inch 

 flow pipes, placing one upon each plate 

 and the other three feet below the 

 ridge. There is no special objection to 

 using 3-inch pipe for the flows upon 

 the plates, but we prefer a smaller size 

 for the middle flow. 



For the returns in a house not more 

 than fifty feet in length, it makes little 

 difference whether 2-inch or 1%-inch 

 pipe is used. For the house in ques- 

 tion, twelve 2- inch or fifteen 1%-inch 

 pipes would be required. These should 

 be arranged in three coils of four or 

 five pipes each. 



The highest part of the flow pipes 

 should be near the heater, and they 

 should be given a gradual fall. One 

 inch in ten or fifteen feet will be ample. 

 The expansion tank should be con- 

 nected with the highest point of the 

 flow pipes.

KROESCHELL TUBELESS BOILER 

 For Steam, Hot Wator, Vapor or Vacuum Haating Systame

Chicago, IlUnola. 

 Gentlemen: — 



Now that the flringr 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 

 IVat«r 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. 



This steam boiler I think is a wonder, 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 flne, 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.
