TO MAINTAIN AN EVEN TEMPERATURE IN YOUR GREENHOUSES, USE A 



Foster Pressure 



With this simple device attached to your steam main just inside the greenhouse the pres- 

 sure on the heating coils will be absolutely constant, anywhere from 1 to 16 pounds (whatever 

 the grower sets the Regulator at), no matter how the pressure on the boilers runs up and down. 



If the weather chantres. or the sun heat varies. Instead of turning oh more pipes, just turn a nui on the 

 Regulator, and get more steam, or less steam, at once. Made in sizes from %-inch to IMnch just for this work. 



" The Poster Pressure Regulators which have been installed In our greenhouses are giving 

 perfect satisfaction."— Peter Relnberg, Chicago. March 16, 1910.

The boiler is a traction boiler and is 

 rated at twelve horse-powor. It holds 

 three ban-els of water. Is it large 

 enough for the two liousesf It is tapped 

 in the dome for a 2i/.-in('h pipe, and 

 there are two taps for 2-in('h returns. 

 If I tap tlie dome for a 4 inch flow, will 

 the two 2-inch taj)s liavo to be enlarged? 



To heat the house llxT.! feet, use 

 one 2i/L'-inch flow pipe and six 2-inch 

 returns. Or, if it is preferred to use 

 2-inch pip;> for the flows, two should be 

 run on the plates and each will feed 

 three 2-inch pipes, under tlie benches or 

 on the walls. 



Unless the returns are several feet 

 above the top of the boiler, it will not 

 be advisable to change the piping in the 

 large liouse as proposed, as the circula- 

 tion in the small house would then be 

 poor. Moreover, if the 4-inch main is 

 run along the north wall, it would only 

 take the place of two of tiio li^-inch 

 returns. 



There is nothing which in any way 

 indicates the ssize of the larger house, 

 but the boiler will be able to furnish 

 heat for 1,200 to l.oOO square feet of 

 hot water radiation, except that it 

 should be tapped for another 2i/^-inch 

 rtdw pipe and an additional 2i/>-inch 

 return. 



THE BOILEB ABOVE GBOUND. 



I have under way here, in eastern 

 Iowa, a new greenhouse, l(5xoO. The 

 boiler will be on a level with the house, 

 which runs east and west. The side 

 walls are six feet high, with three feet 

 of glass, and the height to the ridge 

 is ten feet. Both gables are glass. 

 How many 2-inch pipes will be needed 

 on each side wall, to heat the house to 

 not less than 50 degrees, night tem- 

 perature? What size of flow pipe will 

 be required ? C. P. 



While it would be better if the 

 heater could be below the level of the 

 greenhouse floor, it will answer if two 

 2iA-inch flows can be run, with a slight 

 slope, eighteen inches below the ridge 

 to the farther end of the house, where 

 they should connect with coils contain- 

 ing four 2-inch pipes on each wall. The 

 coils should be kept up as near the 

 ., ^. ., level of the plate as possible. If the 

 ^'f ''^AT'-tjstem is run under pn'SBure, it will 

 answer if only one 2i{, inch flow is 

 used, with eight 2-inch returns.

No loss from sudden drops in 

 temperature if you use the 



Hughson Regulating Valve 



In connection with a steam heating plant. Carry 40 or 

 50 pounds pressure on the boiler and set the valye for 6 

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

 worry this winter, if you follow this advice: " Ingtall a 

 HuKhson RearulatlnK Valve when making your
