Greenhouse Heating. 



It is reported that if the rate war 

 among the Pocahontas coal dealers in the 

 Chicago district continues a week or two 

 longer there will be a further 10-cent 

 reduction in the list price. Looks like a 

 good time to buy. 



Subscribers are invited to write the 

 editor of the Heating Department, de- 

 scribing their troubles or asking any 

 questions regarding the heating of green- 

 houses, the piping or boiler-room. But 

 please do not ask us to make a choice of 

 apparatus for you. Each article adver- 

 tised in this department of The Review 

 is good, and the advertisers sell them on 

 their merits. 



ONE KANSAS HOUSE. 



I have a greenhouse, 24x80, and I 

 wish to install a heating system. I 

 have been advised to put in a st;3am 

 vacuum system. Would this be better 

 than hot water? I shall probably ex- 

 tend the plant. E. G. C. 



For houses up to 200 feet in length, 

 where the boiler can be placed below 

 the level of the returns, many growers 

 prefer an open tank hot water system 

 to any other. Use one 2% -inch flow 

 for three 2-inch returns in each coil, 

 and use as many coils as are needed to 

 furnish the temperature desired. In 

 shorter houses a larger number of re- 

 turns can be supplied by a 2V^-inch 

 flow pipe, but care should be taken that 

 there is no more than 400 square feet 

 of radiating surface, including that of 

 the flow pipe. 



About four coils, each consisting of 

 one 2V2-inch flow pipe and three 2-inch 

 returns, or three coils with four re- 

 turns, will heat a house 24x80 feet to 

 60 degrees. 



HEATED BY A HOT AIE FLUE. 



I am building a greenhouse, 12x25 

 feet and nine feet high to the ridge, 

 with 4-foot double walls. There are 

 two feet of glass in the south side and 

 the east end is glass. I wish to heat 

 it with a flue. What kind and size of 

 flue will be best and what size of fire- 

 box will be required! I want a tem- 

 perature of 55 to 60 degrees, with the 

 outside temperature sometimes as low 

 as 15 degrees below zero. The house 

 is fairly well protected from wind. The 

 location is New York state. J. E. 



To heat a house 12x25 feet to 60 

 degrees by means of a hot air flue, 

 build a furnace at one end, about three 

 to four feet long, fifteen inches wide 

 and eighteen inches high inside, and 

 then run a brick flue, about 8x12 

 inches, from the furnace to the farther 

 end of the house. Care should be taken
