Greenhouse Heating. 



SuBSCRiBEEs 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. 



A SMALL, COOL LEAN-TO. 



One of my customers has a small 

 lean-to in which he wishes to grow an 

 assortment of plants, and he wants to 

 know the best method of heating it, 

 with the minimum of attention, with- 

 out . harming the plants and without 

 going to the expense of piping the 

 room. Would a stove, burning coke, 

 be injurious to the plants t He would 

 use an oil stove, but is afraid of fire. 

 Any suggestions from your heating ex- 

 pert will be thankfully received. The 

 outside temperature here, in the ex- 

 treme south of Illinois, seldom drops 

 lower than 15 degrees above zero, and 

 he just wants to keep thet place above 

 the freezing point. 



Had the size of the lean-to been 

 given, a better idea of the require- 

 ments would have been furnished, but 

 if the house is not more than ten feet 

 wide and fifteen feet long a stoVe 

 would more than keep out frost, and 

 coke could be used without danger of 

 injuring the plants. Even if the house 

 is twenty- five or thirty feet in length, 

 if the smoke pipe can be carried to a 

 chimney at the farther end of the 

 house, it would be possible to main- 

 tain a temperature of 40 to 50 de- 

 grees in cold weather. Provided the 

 floor is of earth or concrete, there 

 would be little danger of fire from 

 using an oil stove, of modern construc- 

 tion, if it is kept away from the walls 

 and benches. 



THBEE PARTITIONED HOUSES. 



Kindly let me know how to pipe the 

 three houses shown in the enclosed 

 sketch, for low pressure steam; also 

 please say what size of boiler will be 

 needed. Our location is western Penn- 

 sylvania. C. B. 



The sketch shows three parallel 

 bouses, with the boiler at one end. 

 House No, 1 appears to be 20 x 100 

 feet, and a temperature of 60 degrees 

 is desired at one end of this house and 

 56 degrees at the other. House No. 2

By automatically returning the condensation directly to boilers at almost 

 evaporation temperature, "Detroit" Traps effect a great saving in coal.
