Greenhouse Heating. 



CAPACITY OF BOILBE. 



We are planning to build one more 

 greenhouse, 28x80, here in eastern Kan- 

 sas. We now have four houses, of the 

 following dimensions: two, each 18x100, 

 one 22x85 and one 15x65. Our boiler is 

 a 40-inch steam tubular, with thirty-two 

 3-inch flues, each twelve feet long, and 

 a 21^ -inch steam outlet. Can we heat 

 the fifth house also with this one boiler, 

 carrying a carnation temperature, in 

 weather about 5 degrees below zero? 

 Last winter we went through weather 

 18 degrees below zero, with our four 

 houses, and this seemed to be no load 

 at all for the boiler. J. W. P. 



From the description the boiler seems 

 to be of about thirty-two horse-power, 

 and it would appear to be amply large 

 enough to furnish a carnation tempera- 

 ture for the houses described, even at 10 

 degrees below zero. While it would be 

 better to have a 3-inch opening, the 

 smaller size will answer if the distance 

 is not too great from the boiler to 

 where the feed pipe for the first house 

 is taken off. 



TO IMPBOVE THE OntOXJI.ATION. 



I have installed a Honeywell genera- 

 tor in my hot water system and I have 

 put it on the return pipe, close to the 

 boiler and between it and the expansion 

 tank. In house No. 1 the pipes run on 

 an up grade around the house and re- 

 turn the same way, with the same grade 

 down for the returns. At the return 

 elbow a 1-inch pipe is attached, leading 

 to the tank. 



In house No. 2 the flows run overhead 

 to the farthest and highest point, where 

 there are two air-cocks, and return in 

 manifolds. It is on the return in this 

 house that I have put the generator, and 

 I find that the 1-inch pipes from the 

 highest point in house No. 1, which 

 are under the beds, give great expan- 

 sion. Can I feed the boiler with the 

 pipe the generator is on? If so, I can 

 get along all right. If I cannot feed 

 the boiler on this line, will it be satis- 

 factory to plug up the 1-inch pipe in 

 house No. 1 and put in a pipe from the 

 tank to the bottom of the boiler t My 

 boiler is a sectional Peerless. The cir- 

 culation is fairly good, but I think — 

 in fact, I am sure — that I can get 

 better results. C. W. B. 



The circulation in both houses will be 

 improved if the flow pipes can be raised

No loss from sudden drops in 

 temperature if you use the 



Hughson Regulating Valve 



In connection with a steam heatinsr plant. Carry 40 or 

 50 pounds pressure on ttie boiler and set the valve for 5 

 or 10 pounds— it will do the rest You'll be free from 

 worry this winter, if ynu follow this advice : " Install a 

 HuKbson Resrulatinc Valve when making your 

 repairs." Ask Tor our Catalogue, which also shows 

 Steam Traps and other devices.

80 that the highest point will be near 

 the boiler. This should be an easy 

 matter in house No. 2 and can probably 

 be arranged without much trouble in 

 house No. 1. If this is done, merely 

 connect the highest point of each flow 

 pipe with the expansion tank. It will 

 answer, however, if one pipe only is 

 connected and an air-cock placed on the 

 highest point of the other flow pipe.
