ADDING A OABNATION HOUSE. 



Last fall we received instructions 

 from you for the heating of one green- 

 house, and the plan you suggested 

 worked excellently; so we will now ask 

 you to give us your idea as to the 

 piping or a new carnation house that 

 we are putting up. Enclosed you will 

 find a sketch of the houses. The new 

 house is to run in the same direction 

 as the other one, north and south, and 

 will be 25x112. The walls will be 

 seven feet higk to the gutters and will 

 contain foue fe«t of glass over three 

 feet of concrete. We wish to heat this 

 house with the hot water boiler which 

 is already in use for the other house, 

 «s the boiler is amply large enough for 

 fte entire space. We wish to run the 

 new house at a carnation temperature. 

 The new house will be divided from the 

 other by a glass partition and will have 

 glass in both ends. The boiler is at 

 the south end of the houses; the uorth 

 end is partly protected by a store- 

 room. Th« location is central Indiana.

For heating a carnation house 25x112 

 feet, with hot water, in central In- 

 diana, I would advise the use of three 

 2% -inch flow pipes, one of which would 

 be placed upon each plate and the 

 other three -feet below the ridge. For 

 the returns I would use three 2-inch 

 pipes on each of the side walls or under 

 the side benches, and four returns 

 under the middle benches, the latter 

 to be supplied by the middle flow pipe. 

 The main returns should be of the 

 same size as the flow pipes. For this 

 purpose a single 4-inch pipe could be 

 used, or the 2%-inch flow and return 

 pipes could start at the boiler. 



EXTRA BOILES FOB BOSE HOUSE. 



I am heating my greenhouses with 

 hot water, but it seems difficult to keep 

 mildew off roses without steam heat. 

 I am figuring, therefore, on buying a 

 small steam boiler for occasional use 

 in the rose house. I can buy a second- 

 hand steam boiler, in good condition. 

 It has been used for running a con- 

 crete mixer. It is an upright boiler, 

 of six horse-power, and contains thirty- 

 one 2-inch flues, twenty-nine inches 

 long. The grate is nineteen inches in 

 diameter and the fireplace is seventeen 

 inches high from the grate to the flues. 

 Can this boiler be used for heating 

 purposes by having a hood made at the 

 top and bottom t If so, how many feet 

 of 1-inch or 1%-inch pipe can be con- 

 nected to the boiler, running ten or 

 fifteen pounds of steam? Would it be 

 advisable. to buy such a boiler? I am 

 located, you will notice, in northern 

 Colorado. P. O. H. 



There should be no difficulty in grow- 

 ing roses free from mildew in green- 

 houses heated with hot water, if proper 

 attention is given to firing and venti- 

 lating and if the radiation is ample 

 and properly arranged. In a small 

 house, hot water heat is preferable to 

 steam, especially when a boiler as small 

 as the one described is to be used for 

 steam. With a boiler having a 19-inch 

 grate I would not care to risk more 

 than 200 square feet of radiating sur- 

 face and would only use IV^-inch pipe 

 for the overhead flow, putting in 1^-
