Greenhoase Heating. 



SLOPE OF STEAM PIPES. 



We are heating our greenhouse with 

 steam. The pipes are four feet above the 

 boiler at the farther end and the returns 

 are six inches above at the main return. 

 Will any valve or trap be needed to put 

 the water back into the boiler! If so, 

 what kind? B. B. & C. 



If I understand your statement cor- 

 rectly there should be little diflSculty in 

 returning the water in this system, al- 

 though it would be better if the returns 

 near the boiler were at least two feet 

 above it. If the returns are four feet 

 higher than the boiler at the distant end, 

 will it not be possible to lessen tne grade 

 in the returns and increase the vertical 

 drop to the main return near the boiler 

 to at least two feet, or two feet and a 

 half? This would be a great safeguard. 

 In any event, place a swing check valve 

 in the main return. If the system does 

 not work well, give a more complete de- 

 scription* of the plant and we will en- 

 deavor to give you further assistance.

PIPING IN PENNSYLVANIA. 



I will build a propagating house at 

 once, 16x40 feet, ten feet to the ridge, 

 and exposed on all sides. I should like 

 to get your advice in regard to heating it 

 with hot water or steam. I will add 

 sixty feet more in the spring and will 

 heat from another building then. 



What size of grate surface will I need 

 to heat to 50 degrees, with zero tempera- 

 ture outside, 6,600 feet of glass, ten feet 

 to ridge, houses 66x100 feet? 



J. G. S. 



If you heat the propagating house 

 with steam, install a 2-inch flow or riser 

 under the ridge and twelve 1%-inch 

 pipes as returns under the benches. If 

 you use hot water, use a 2-inch flow un- 

 der the ridge and twelve 2-iuch returns 

 under the benches, or use one of the 

 pipes under each of the three benches 

 as a supply and three as returns, thus 

 making three flows and nine returns in 

 the house. 



To heat the bank of houses 66x100, it 

 will be necessary to install twenty-six 

 lines of li4-'nch pipe, supplied from a 

 2-inch flow under each ridge; or, if hot 

 water in 2-inch pipe is used, install 

 twenty-four 2-inch returns, to be sup-

Steam Heating on an 

 Economical Vacuum Principle 



The Simonda Automatic Vacuum VaWe has 



MANY advantag^es over any other vacuum 



vaWe in the world. 



Thlnlc of a ^-inch valve with a ^^-incb clear dlBCharKe opening 

 under the valve. They won't easily clog with dirt or ruat. will they? 



Of an air disrbarire valve Above the water JId" and tlcht on its 

 seat, except while water discharge valve Is open. Can't ivaste steam 

 when not open, can ii? 



Of an adjustment to tbi< air discharge valve that allows of reduc- 

 ing the dlRcaarge to a piu point. Won't waste steam when discharg- 

 ing, will it? 



Of no Kulde winar* or pins under water discharee valve.

 ■eats after all is heated up. and expansion has taken 

 place. 



Pretty near tbe correct principle, ain't it? 

 Our ompnund Vacuum Steam Heating System com- 

 bines with the valve to secure tbe higbe»t economy in 

 steam, and complete circulation >n even the largest

 have a rated capacity for 1,800 to 2,000

PIPING IN MISSOURI. 



I am erecting an addition to an old 

 house. Will you please state how much 

 1-inch pipe I will need for heating, as I 

 would like to run l^^-inch pipe for feed- 

 ing overhead? The new addition is 18x 

 36 feet. The side walls are five feet high 

 and it measures eleven feet and one-half 

 to the ridge. The house runs east and 

 west ; the northern exposure is all boards 

 up to the gutter. Both gable ends are 

 glass and the south side is partly glass. 

 I will carry twelve pounds of steam and 

 would like to keep the house at 60 de- 

 grees in zero weather. M. H. 



i To heat the room ]8x.36 with steam, 

 ■using 1-inch pipe, it will be necessary to 

 install seventeen returns, which can be 

 supplied from the ]i/4-inch flow under 

 the ridge. It will be well to provide 

 valves on some of the returns, so as to 

 throw them out of commission during 

 mild weather. L. C. C.

 you answer my question as to how much 

 4-inch pipe would be required to heat a 

 propagating house 12x90, and state that
