90 



length of the pipe, if arranged as pro- 

 posed, will make the circulation ex- 

 tremely sluggish. It would be prefer- 

 able to run two 214-inch flow pipes, 

 supplying with each of them the radia- 

 tion in two of the houses. The size of 

 these flow pipes may be reduced to 2- 

 inch after the radiation in the first 

 house has been connected. Two-inch 

 pipe should be used for the radiation in 

 the houses, and the returns, instead of 

 running back and forth through the 

 houses, should be connected directly 

 with the main returns, which should be 

 of the same size as the main flow pipes. 

 Where more than two lines of 2-inch 

 pipe are needed in a house, one 2-inch 

 flow can be used to supply as many 

 as three or four 2-inch returns. 



Since the circulation to the highest 

 house will be most rapid, valves should 

 be provided to equalize the circulation 

 to the different houses. 



CHIMNEY NOT LARGE ENOUOH. 



Enclosed is a rough sketch of my 

 greenhouses. I am using a Wilks hot 

 water boiler, 42x48. I cannot heat the 

 small house with the six 2-inch returns 

 now installed. I am putting in another 

 boiler, 36x48, of the same make. Can 

 I use the present six 2-inch returns and 

 how many more will be needed to heat 

 the small house to a temperature of 60 

 degrees in zero weather! The chimney 

 has a flue 12x12 inches and is twenty 

 feet high; will it serve for both boilers? 



W. S.— 111. 



The sketch shows two houses 100 

 feet in length and twenty-seven and 

 fourteen feet in width, respectively, 

 with two feet of glass in one exposed 

 wall in each house. For the narrow 

 house I would suggest the use of three 

 2%-inch flow pipes, running one upon 

 each plate and the other two feet under 

 the ridge. As returns, use six 2-inch 

 pipes in three coils, connecting one of 

 the coils to each of the flow pipes. The 

 boiler for this house should be rated 

 for 900 to 1,000 square feet of radia- 

 tion. 



While the chimney is amply large for 

 one of the boilers, it would not answer 

 for both of them. The flue for a boiler 

 large enough to heat the small house 

 should be ten inches in diameter. A 

 taller chimney would give better re- 

 sults. 



A NEW KEROSENE BUBNEB. 



I have a small greenhouse, 12x25, 

 about eight feet high and containing 

 about 300 square feet of glass. Do you 

 think I could heat this house with a 

 coal oil burner that generates gas from 

 the oil, as told in the enclosed circular 

 from the Kero-Gas Co., of Kansas City, 

 Mo.t The circular, you will notice, 

 contains illustrations showing the use 

 of the Kero-Gas burner for both cooking 

 and heating. Would it be necessary to 

 run pipes from the heater under the 

 benches? C. F.— Kan. 



I have no knowledge of the Kero-Gas 

 burner described in the circular, but 

 kerosene contains more heat units than 

 most of the common fuels and, if the 

 burner described vaporizes it properly, 

 will be found economical and efficient. 



Unless some method of distributing 

 the heat is provided, it will not be pos- 

 sible to secure a uniform temperature 

 in cold weather, especially when high
