 Will two flows be sufficient, or would it 

 bo better to use three to increase the 

 circulation? 



1 am using- a G-section Mills water 

 tube boiler rated at 1,875 feet of radia- 

 tion, more than I need, but it is said 

 to be easier on the coal pile as well as 

 the fireman. The top of the boiler is 

 eiglitreu iinlie.-i below the fireenliousc 

 floor; so there will be at least a otiinch 

 droji from the east end of the house to 

 the boiler. The reason I don't want 

 lieat under the center bench is because 

 I wish to use that section for mums, 

 followed bv sna])dragons.

Fiom the dat.a furnished we estimate 

 that fully 440 scpiare feet of radiation 

 will l»e required to maintain a tenijx'ra- 

 ture of ()0 degrees in zero weather with 

 hot water. Tlic pipe listed will only 

 supjdy about 235 square feet, and as jht 

 hajis fifteen to twenty feet additional 

 will be needed to connect with the 

 boiler it will be necessary to ])urch;ise 

 more than 2(ii) sfpiare feet of radiation. 



That being the case, we reconnuend 

 tliat 2Vi'-iiich pipe be used for the main 

 flows and returns. 



Instead of running the flow pipes on 

 tlie plates, we should support them on 

 tlie juirlin posts near the sashbars, and 

 aftci- dropjiing them down at the far- 

 ther end of the liouse to a point bcdow 

 the benclies, we should start the wall 

 coils at those points and run them to 

 the corners of the house and then along 

 the side walls. 



On the north side of the house we 

 sliould use a coil of six IVi-inch returns, 

 with the west end of the coil near the 

 door. For the south coil use the re- 

 mainder of the IJ/i-inch pipe for two I

Help Save the "White 

 Coal of Industry" 



The boiling hot water resulting from condensation in 

 your steam lines is worth money. You have paid for 

 it in terms of coal. It contains valuable heat units. 

 It is the ''White Coal of Industry" — it should not 

 be wasted. 



And it need not be wasted. The Morehead Back- to - 

 Boiler System will save it for you by returning it to 

 the boiler at temperatures as high as 400 degrees 

 Fahrenheit. It reduces coal consumption an average 

 of 20%. At the same time your steam will be 

 "drier" and more eflScient; your production speeded 

 up and profits increased. 



Write today for facts and figures on what the More- 

 head System will do in your plant.
