Greenhouse Heating. 



The market for smokeless coals is not 

 only strong but getting stronger; at least 

 the coal trade is so confident that there 

 is to be a big demand for this class of 

 fuel this winter that scant attention is 

 paid to the buyer who thinks he should 

 get a concession in price. 



CAPACITY OF BOILER. 



V. 



What is the capacity of a tubular 

 boiler, 3x15 feet, with a 24-inch dome, 

 twenty-four 3-inch flues and a grate 30x 

 48 inches. How many square feet of 

 glass will it heat to 50 degrees when 

 it is zero' outside, using ten to fifteen 

 )iounds of steam, with a gravity sys- 

 tem* .T. W. C. 



The boiler can be safely rated at 

 thirtv horse-power, and it should heat 

 from' 12,000 to 15,000 square feet of 

 glass to 50 degrees under the con- 

 ditions named. 



A HORIZONTAL SMOKE FLUE., 



The boiler for heating my green- 

 houses is in the basement of my dwell- 

 ing. 1 am planning to build a new 

 chijnney, about thirty feet away from 

 the boiler. What size of chimney and 

 what size of flue would I- need? My 

 neighbor's house is about six feet 

 higher than mine. The smoke pipe of 

 the boiler is eight inches in diameter. 

 P. H. 



It is a difiicult matter to carry a 

 smoke pipe for thirty feet horizontally. 

 Therefore, to improve the draft, the 

 chimney should be larger in diameter 

 and higher than would otherwise be 

 required. I would suggest that in ease 

 the 8-inch smoke pipe is large enough 

 for the boiler, the chimney be made 

 twelve inches in diameter and thirty- 

 five or more feet high, or at least five 

 feet higher than any of the surround- 

 ing buildings. 



IN SOUTHERN INDIANA. 



I am building a greenhouse eighty 

 feet long and eight feet high to the 

 lidge, with 4-foot wooden side walls. 

 It is joined to another house, but the 

 east side and north end are exposed. 

 Will you kindly inform me as to the 

 best way to pipe this house so as to 

 heat it ' to 60 or 65 degrees in zero 

 weather? F. H. H. 



The letter does not appear to give 

 the width of the new greenhouse, and 

 without that no definite suggestions 

 can be made. Neither does it imply

whether the building is to be heated 

 with steam or hot water. 



In case the house is 20 feet wide 

 and hot water is to be used, it is sug- 

 gested that three 2 '/.-inch flow pipes 

 be used. One of these should be on 

 each wall and the other under the 

 ridge. In addition to the flow pipes, 

 nine 2-inch returns should be used. 

 Three of the returns can be in coils 

 upon each side wall and the others un- 

 der the middle bench. For steam in 

 a house of the same width, take one 

 2-inch flow pipe and nine lV4-inch re- 

 turns. For houses wider or narrower 

 than twenty feet, use proportionately 

 more or less pipe. 



THBEE HOUSES AND A FBAME. 



We are going to build two green- 

 houses, here in southeastern New Hamj)- 

 shire. The dimensions of the houses 

 will be as follows: No. 1 will be 

 15x75 and nine feet to the ridge. One 

 end will be glass, except three feet, 

 which will be boarded. The back wall 

 will be five feet high, the front wall 

 four feet, all boarded. The houses will 

 run east and west. House No. 2 will 

 be 13i/L.x75, with a gable the same as 

 No. 1. The walls will be four feet 

 high, and boarded. At the west end 



will be the boiler, in the service house, 

 which will run across the ends of the 

 two houses. ; 



Please state the-b'est way to heat the 

 houses to a temperature of 50 to 55 de- 

 grees when the fi):^ide temperature is 

 at zero. We sha© Beat with hot water. 

 We have been thinking of using a 

 2iXj-inch flow under the ridge and 2-inch 

 returns under the side benches. If 

 there is a better way, please describe 

 it. Also state the number of feet of 

 2-inch pipe required, and the size of 

 boiler, to heat these two houses and 

 another one, 18x75, which will be added 

 next year. The 13 Mj -foot house will 

 be in front of the 15-foot house, and 

 we should like to know whether we 

 could heat a frame, 6x75 feet, by run- 

 ning two returns from the side of the 

 ]3V_>-foot house. The frame will be 

 used for bedding plants, and not until 

 about March 15. Please state the right 

 size and position of the expansion 

 tank, and the height and diameter of 

 the smokestack. The boiler pit will be 

 seven feet deep. 



A. H. C. &. S. 



The houses are rather large to be 

 heated by a single 2M'-inch flow pipe, 

 and it will be better to use two 2^{.- 

 inch flows or three 2-inch flows in ea«h
