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 article adver- 

 tised in this department of The Review 

 is good, and the advertisers sell them on 

 their merits. 



rOUB CALIFORNIA HOUSES. 



I have four greenhouses, each 27x200, 

 with walls five feet high and the ridge 

 thirteen feet from the floor. What 

 amount of piping will be necessary for 

 these houses? S. M. 



The question does not give the use to 

 which the houses are to be put; hence no 

 really definite advice as to the amount of 

 radiation can be given. In the climate 

 of central California, a greenhouse 27x 

 200 feet, with a wooden wall five feet 

 high, will require about 800 square feet 

 of steam radiation, provided a tempera- 

 ture of 60 degrees will suffice. This 

 amount of radiation can be provided by 

 means of one 2%,-inch main overhead, in 

 the center of the house, and eight 1 14- 

 inch returns. The returns can be partly 

 on the walls and partly under the benches. 

 For four houses of this size, a 4-inch 

 main would answer. 



STEAM FOB LETTUCE HOUSES. 



I am building two iron-frame, trussed 

 houses, each 28x141, here in western 

 Iowa, and will heat them with gravity 

 steam. Please inform me as to the 

 right size and location of the heating 

 pipes. The height from floor to eaves 

 will be seven f«et. The houses will be 

 connected, without partition, and will 

 thus be equivalent to one house 56x141. 

 There will be four feet of glass in the 

 sides. The south end will be glass; the 

 north end will be boarded and papered. 

 The foundations will be concrete. The 

 houses will be used for growing lettuce 

 all winter. There will be no benches; 

 the lettuce will be planted on the floor. 

 There will be a walk all around, close 

 to the wall, and a walk through the 

 center. I think a temperature of 40 

 degrees in zero weather will be warm 

 enough. M. K. B. 



Each of the houses, 28x141 f^t, with 

 four feet of glass in one wall, can be 

 heated with steam for growing lettuce 

 by using two l^^-inch mains and eight 

 1^-inch returns. The flows can be on 

 the purlin braces and five of the re-
