Where There Is Coodeosatioo 



— there is need for a Morehead Steam Trap. Condensation in 

 steam lines is akin to matter out of place — means wasted energy. 

 If your lines are sluggish — if your houses are not of uniform 

 temperature, write us. We guarantee to drain your lines per- 

 fectly — return the pure, hot condensation to your boiler without 

 pump or injector or make no charge for the trial. Obey that 

 impulse — write now.

ature in this part of Ohio seldom falls 

 lower than 10 degrees below zero. I 

 have a east-iron boiler, rated for 700 

 square feet. Will it heat all the houses? 



J. E. S. 



It will be well to run a 2i4-inch flow 

 pipe from the boiler to the middle of 

 the east end of the carnation house, 

 where a li/2-inch flow^hould be taken 

 oflP for that house an5 the main con- 

 tinued as a l^^-inch flOw fo supply the 

 lettuce house. To supply the begonia 

 and rose houses, a 2V2-inch flow should 

 be carried overhead in the begonia 

 house and, after being reduced to iy2- 

 inch, should be continued through the 

 rose house to the south end. 



In addition to the overhead flow pipes 

 in each of the houses, the following 

 returns will be required: For the let- 

 tuce house use four iy2-inch; in the 

 carnation house use four returns; for 

 the begonia house four returns will 

 be sufficient; the rose house will re- 

 quire six 11/^ -inch returns, in addition 

 to the 1%-inch flow pipe which passes 

 through each house under the ridge. 

 A boiler of the size mentioned should 

 be amply large to heat the houses. 



HOT WATEE OR STEAM. 



I expect to erect a greenhouse 28x125 

 near a river. On account of striking 

 water, I can not dig deeper than four 

 feet for the boiler pit. Is it possible, 

 with this depth for the pit, to put in a 

 hot water system? If not, is steam 

 heating practical for this size of green- 

 house? The location is southern Wis- 

 consin. H. W. W. 



While a deeper boiler pit would be 

 desirable, a good circulation can be se- 

 cured with hot water, under the con- 

 ditions named, by using overhead flow 

 pipes and keeping the returns as high 

 as possible. 



The temperature desired is not given, 

 but for 60 degrees five 2i/^-inch flow 

 pipes and thirteen 2-inch returns should 

 be used. For 50 degrees put in three 

 flows and ten returns. In case there is 

 glass in the side walls, use an addi- 

 tional return for each two feet of glass. 

 Bun one flow pipe on each plate and one 

 under the ridge. If five flows are put 

 in, the others should be under the 

 purlins. 



The size of the main flow and return

insure a more uniform tem- 

 perature in the houses by 

 keeping all steam lines free 

 and clear of condensation. 



Sluggish lines sap the real 

 heat value out of the new 

 steam and add dangerously 

 to the general inefficiency 

 of the plant. 



Avoid this condition in 

 your system by installing 

 a "Detroit" Return Trap. 



Bulletin No. 326-WF gives details of construction, operation 

 and application of Detroit Traps. Yours upon request.

 selection of the proper size " Detroit " Trap for your requirements, write us.
