Where There Is Condensation 



— 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 hoiler without 

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

 impulse— write now. . - ^ - J : •

enough for 20,000 feet of glass and 

 hence is not economical of fuel. 



Crude oil will not be found an eco- 

 nomical fuel except where the quantity 

 to be used is sufficient to warrant ship- 

 ping it in tank cars. 



FEEDING THE COILS. 



I have had trouble with lack of cir- 

 culation in the pipes and laid the trou- 

 ble to lack of depth in the boiler pit. 

 The boiler has now been lowered so 

 that it is considerably lower than the 

 level of the greenhouse. At present the 

 coUs, live pipes in each, are fed from 

 the top of the header. Before the top 

 of the boiler was on a level with the 

 top pipe in the coil. Will it be neces- 

 sary to change the headers, as a 

 plumber advised us, and feed from the 

 bottom of the header f E. C. S. 



The data given is hardly complete 

 enough to warrant a definite answer. 

 If the coils are connected directly to 

 the boiler, it wonld make little differ- 

 ence, and bottom connection could be 

 used, but if the flow pipe is carried at 

 a slight fall to the farther end of the 

 house, as would be preferred, the con- 

 nection should be at the top of the 

 coils. With this arrangement there is 

 less reason for keeping the boiler below 

 the returns, than when the coils are 

 closely connected with the boiler. 



RADIATION FOB FOUB HOUSES. 



We have a range of four houses 

 running east and west. The two south 

 houses are 28*4x100, then comes one 

 14x100, and one 15x100, with a lean-to 

 on the north side 5x100. The houses 

 are all six feet to the eaves or gutters, 

 with the outside wall of the lean-to 

 four feet ten inches high. The two 

 wide houses are fourteen feet to the 

 ridge, the others eleven feet, all con- 

 nected. We figure it as 10,300 feet of 

 glass. The potting shed is on the west 

 end. Will you please tell us how many 

 feet of radiation we need for steam or 

 hot water, to maintain 60 degrees in 10 

 degrees below zero weather? H. F. C. 



Whether the walls contain any glass 

 is not indicated. For the two houses 

 28%xl00 feet, if to be heated with 

 hot water, use five 2^4-inch flow pipes

RETURN TRAPS 



BECAUSE 



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.

Pipe Carriers 



We have a line that cannot be excelled. The 

 steel hook is neat, light, very strong, and stamped 

 from the best sheet steel. The prices are very 

 reasonable. 



Let us figure on your needs at least. However, 

 we know that a trial order will show you that our 

 pipe carriers are the beet. Get our prices.

and thirteen 2-inch returns, with an 

 additional return for each two feet of 

 glass in the south wall. With steam 

 one 2%-inch flow and eleven 1%-inch 

 returns will be needed. 



To heat the other houses, which are 

 respectively fourteen and fifteen feet 

 in width, use three Z^-inch flows for 

 hot water, with six 2-inch returns, or
