— thwe^Tneed for a Morehead Steam Trap. Condensation in 

 steam lifl^s is akin to matter out of place — means wasted energy. 

 If your J^ines 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

greenhouse, 18x50, to 55 degrees in this 

 Ohio climate f I have a quantity of 

 1%-inch pipe which I want to use. The 

 house is tightly built. R. B. K. 



The letter does not state whether 

 steam or hot water is to be used. For 

 steam put in one 2-inch flow pipe and 

 six 114-inch returns. To use 1%-ineh 

 pipe for hot water, put in twelve re- 

 turns, in addition to two 2%-inch flow 

 pipes on the plates. It would be better, 

 howeyer, to use eight 2-inch returns in- 

 stead of the twelve 1%-inch returns, 

 for hot water. 



IN NEW YORK STATE. 



We have one old house, 30x100 and 

 ten feet to the ridge, with the eaves 

 close to the ground. One end is glass. 

 The house is fairly tight. It is heated 

 with a Florida steam boiler, No. 225. 

 It contains two 2%-inch flow pipes and 

 fourteen li4-inch return pipes. Eight 

 of these returns are badly split; so we 

 shall have to take them out. We are 

 going to grow lettuce and violets. Can 

 we change from steam to hot water, 

 and how many 134-inch return pipes 

 would we need! 



We are also building three new 

 houses. Two of them are connected 

 and are each 25x100 and five feet to 

 the eaves, with two feet of glass and 

 one end glass. The height to the 

 ridge is eleven feet. In these houses 

 we want a temperature of 50 degrees. 

 We intend to put in two 2%-inch flow 

 pipes and eleven 2-inch returns. Would 

 that be enough, or would you advise us 

 to get larger flow pipes and more re- 

 turns! The other new house is sep- 

 arate; it is 20x90 and ten feet to the 

 ridge, with two feet of glass in each 

 side and one end glass. In this house 

 we want a temperature of 60 degrees. 

 We have one 3%-inch flow pipe and in- 

 tend to have 2-inch returns. How many 

 returns do we need? O. S. M. 



To heat the old house, 30x100 feet, 

 with hot water, use two 2i^-inch flow 

 pipes and eight 2-inch returns, in addi- 

 tion to using the six uncracked 134- 

 inch returns. If it is desired to use all 

 134-inch returns, eighteen will be re- 

 quired. 



In the new houses 25x100, the plan 

 of piping proposed could be used, but 

 it would be better to put in three 234-

they drain all the condensation from all the steam coils and 

 automatically return it directly to the boiler hot. Not a 

 drop is wasted. None of the heat is lost.
