ON PA6E 



565, Jan. 10- 



issue of this publication there appeared 

 an advertisement for the sale of a green- 

 house. One of the first things said about 

 the plant was that 



Morehead 

 Steam Traps 



WERE INSTALLED 



When the fact that Morehead Steam 

 Traps installed in a plant is used as one 

 of the first talking points in order to 

 effect a sale of the plant, illu.strates in a 

 most convincing way what the user thinks 

 of the MOREHEAD. 



Are you satisfied with the operation of 

 your fcteam system ? 



Have you condensation troubles ? 



We have the remedy for your heating 

 troubles. Write us for our Florists' Cat- 

 alogue.

the harder you fire the worse it is, as 

 the hotter the water the more ready it 

 is to escape through those openings and 

 return to the boiler. 



If this is about the way the pipes are 

 laid out, the tees from the main to the 

 flows should be on their sides, with a 

 piece of horizontal pipe eighteen inches 

 or two feet long with an elbow to the 

 riser. I would also reduce tnis piece of 

 horizontal pipe to three inches in the 

 first three branches and shorten the other 

 two to twelve inches, and let the last one 

 be a mere nipple; or let the outlet be on 

 the upper side. I have found it bad prac- 

 tice to take branches from the upper 

 side for hot water without reducing them 

 by at least one-half or putting on a 

 valve in the riser to control the flow 

 when there are branches taken off be- 

 yond on the same main. 



A valve between the boilers is not nec- 

 essary. They can both be connected up

to the main flow and return, and either 

 or both boilers be used at the same 

 time. His boiler-room will not be so 

 warm if a proper circulation is obtained 

 in the pipes, which this arrangement 

 should give. R. G. Milford. 



ELEVATE EXPANSION TANK. 



I would like to say a few words in 

 reply to the article by E. G. Milford in 

 the Review of January 10. When he 

 says that the height of the expansion 

 tank has no bearing on the efficiency of 

 the heating plant, I have to differ with 

 him. I do not mean that it has any 

 effect on the circulation ; but with a 

 high tank it is possible to heat the water 

 to considerably more than 212 degrees, 

 which is of great importance in a very 

 cold spell. 



Where a water supply tank is neces- 

 sary, as in most country places, it is 

 by far the best expansion tank that 

 could be devised. Sline is something 

 over forty feet above the boiler, giving a 

 pressure of about twenty pounds, and, 

 in consequence, we have several times 

 run all night with the hot water ther- 

 mometer showing 230 to 240 degrees. 

 If any one thinks this is not greater effi- 

 ciency than a low tank could give, let 

 him try it in unusually cold weather. 



My connection is as follows: The tank 

 is at the farther end of the greenhouse 

 from the boiler, about 150 feet. The 

 1^/^-inch main supply pipe from the tank

runs under the first bench to the boiler- 

 pit and into a return near the boiler, and 

 is tapped in several places for water 

 pipes to run through the various houses. 

 A %-inch pipe is taken from the flow on 

 the heating coil nearest the tank and 

 runs up and into the tank beside the 

 supply pipe. Thus I have a constant 

 circulation of hot water from the boiler 

 to the tank and down to the supply pipe. 

 On the %-inch pipe to the tank there is 

 a brass stop-cock which is nearly closed; 

 only an opening is left about the thick- 

 ness of a knife-blade. This is ample 

 and prevents waste of heat. 



The principal advantage of this circu- 

 lation is, that there is no danger of any 

 pipes to the tank freezing in any weather, 

 even if they were entirely uncovered ; 

 and your tank water is always warm for 

 watering plants. W. E. Gray. 



PIPE FOR HEATING. 



I intend to build a carnation house 

 14x90. The mercury sometimes reaches 

 5 degrees below zero. How many 1^- 

 inch returns should be required to main- 

 tain proper temperature? Would 2-inch 

 flows be enough to supply required 

 amount of returns. L. H. 



Yes, two 2-inch flow pipes will be suffi- 

 cient to provide for the radiation in the 

 house 14x90 feet. The piping should 

 consist of two 2-inch flows and twelve 

 11/4 -inch returns. If these can be ar- 

 ranged in two manifolds it will be satis- 

 factory*. L. C. C.

Braceville, O. — Florists here all re-

I THINK the Review is the best paper
