Greenhouse Heating. 



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 boiler adver- 

 tised in The Review is a good boiler, and 

 the advertisers sell them on their merits. 



POCAHONTAS. 



Owing to the alarming shortage of 

 hard coal, the price of all smokeless 

 mine run is scheduled for a raise Au- 

 gust 1, according to those well posted 

 in the coal trade. The present quota- 

 tion for Pocahontas is $1.10, while the 

 first of next month the operators will 

 ask $1.25 and possibly more. The short- 

 age of anthracite is due to the inabil- 

 ity of the mine owners to obtain men, 

 as many left the coal districts when 

 the labor troubles began. As a result, 

 hard coal cannot be had at any reason- 

 able figure, and the surplus soft coal is 

 rapidly being used up. Egg and lump 

 Pocahontas have gone up, with no new 

 supply in sight. The operators, anthra- 

 cite and bituminous, are preparing for 

 a season of high prices. 



A LOUISIANA VEGETABLE HOUSE. 



Please give me information as to the 

 best way of piping my house so as to 

 heat it satisfactorily in this Louisiana 

 climate. I wish to grow seedlings of 

 peppers, eggplants and tomatoes. The 

 house is 9x25 feet, seven feet to the 

 eaves and ten feet to the ridge, with 

 four feet of glass in the sides and both 

 ends glass. The rafters are four feet 

 ten inches. I have a vertical boiler, a 

 Wilks No. 14, with a 10-inch grate and 

 a height of thirty-six inches. I also 

 have a lot of 1-inch pipe that I wish to 

 use. Where should the expansion tank 

 be placed! T. B. W. 



While a temperature of 60 to 65 de- 

 grees should be provided for the start- 

 ing of tomatoes, peppers and eggplants, 

 the amount of artificial heat actually 

 required in Louisiana will not be great. 

 For the flow pipe, a 2-inch pipe should 

 be used and this should be carried over- 

 head, about two feet under the ridge, 

 with a slight fall toward the farther 

 end of the house. The expansion tank 

 should hold about ten gallons and should 

 be connected with the highest part of 

 the flow pipe. It will answer if placed 

 just above the pipe, but it is always de- 

 sirable to have the expansion tank some- 

 what elevated if possible. If the 1-inch 

 pipe is to be used for the returns, ten 

 or twelve should be placed in two coils

under the benches, or on the walls. It 

 would be even better to use six 2-inch 

 pipes for the returns. These should be 

 connected with the flow at the farther 

 end of the house and should be given a 

 slight .fall. 



GREENHOUSE AND BESIDENCE. 



We bought an American sectional 

 boiler, No. 267. With it we expected 

 to heat our greenhouse, 36x50, and our 

 8-room residence, in this Utah climate. 

 We have a hot water system. The pipe 

 leading to the greenhouse, and the re- 

 turn, are 5-inch. There are coils of 3- 

 inch pipe under the benches, four pipes 

 to the coil under two benches and three 

 pipes to the coil under two other benches 



and under the side and end benches. 

 The overhead pipes, on entering the 

 greenhouse, are eight feet five inches 

 high, or thirteen feet eight inches above 

 the floor in the furnace room. The pipes 

 connecting with the dwelling are 3-inch 

 and run under the floor, with scarcely 

 any rise or fall. The furnace is in 

 about the center of the plant. 



The end of the greenhouse where the 

 overhead pipes are located is 10 degrees 

 warmer at night than the opposite end. 

 The front rooms of the dwelling, corre- 

 sponding to the north end of the green- 

 house, do not get much above 50 degrees. 

 There are twenty-eight feet of radiation 

 in the dwelling. The greenhouse heats 

 up nicely. A local architect says the
