The Florists^ Review 



SoHtJAit 21. 1916. 



desirable for a sprinkling system, good 

 work can be done with a head of 

 twenty-five feet. 



For gravity steam heating it is al- 

 ways desirable to have the returns at 

 least two feet above the water level 

 iiji the boiler. If this can be secured, 

 the main return may be connected 

 directly with the bottom of the boiler; 

 otherwise a steam trap should be used 

 to handle the water, but in this case 

 a pressure of about five pounds will 

 be required. 



HEATED WITH COU. BOILEB. 



I am planning ; to build two green- 

 hduses, one of th^m 24x75, the other 

 12X75. The side walls will be 

 five feet high and will contain no glass. 

 The houses will be twelve feet and nine 

 feet high to the ridge, respectively. 

 1 am thinking of using six 2 -inch flows 

 overhead and two 1%-inch returns for 

 each flow, for the two houses. The 

 highest points will be at the end of 

 the houses farthest from the boiler. 

 The boiler will be built of fourteen 

 2-inch pipes, ten feet long, arched over 

 the fire-box, with seven pipes on each 

 side of the arch. Each side of the 

 boiler will supply three flows. What 

 size of grate do I need and will there 

 be enough pipes in the houses and 

 boiler, according to my plan, to keep 

 the temperature at 50 degrees when 

 the mercury outside stands at zerof 

 The location is southeastern Pennsyl- 

 vania. K. D. G. 



While it would be possible to heat 

 the house 24x75 feet to 50 degrees by 

 hieans of four 2-inch flows and eight 

 1%-inch returns, it would be more 

 .economical of fuel and labor if ten 

 returns were used. For the house 12x75, 

 I would suggest the use of two flows 

 and five returns. The foregoing sug- 

 gestions are made with the understand- 

 ing that there is pipe on hand of the 

 sizes mentioned. Otherwise I would use 

 three 2%-inch flow pipes and eight 

 •2-inch returns in the house twenty- 

 four feet wide, and two flows and four 

 returns in the 12-foot house. A grate 

 2x3 feet should be large enough for 

 the two houses. The heating surface 

 in the coil boiler is amply large; in 

 fact, a length of eight feet would 

 aimwer.
