Gentlemen:— You can strongly and unbesltatinrly recommend tht 

 " Eclipse " piston type reducing valve to florists. We have two purchased 

 of you last year. We would not have them out for double their cost and 

 find them as sensitive as a watch. We will be in Chicago soon to take ur 

 the vacuum system with you. Yours truly,

BO great importance, but with hot water 

 in a cold country hold the length of the 

 flow pipes within 100 feet, if possible.

AMOUNT OF RADIATION. 



I have three east and west, three- 

 quarter-span greenhouses to be heated 

 ■with hot water. Each house is 22x200 

 with walls five feet high. The north bar 

 is eighteen feet and the south bar nine 

 feet. Two houses are for carnations and 

 one is for roses. "What kind of boiler 

 do I need to maintain a temperature of 

 60 degrees in the rose house and 52 de- 

 grees in the carnation houses where 

 zero is the coldest weather? I use wood

for fuel. How many feet of radiation 

 will each house require? How many feet 

 of pipe should I use and what size for 

 overhead and under benches, also size of 

 the main? The boiler will be set up at 

 the northwest corner of the north house 

 and on a level with the houses. G. B. 



Your plant with boiler set as suggest- 

 ed can be heated by steam more easily 

 than in any other way; but with wood 

 for fuel hot water heating would be 

 preferable if the boiler can be located 

 so as to reduce the length of the flow 

 pipes to practically 100 feet, which is 

 about the maximum length for hot water 

 on a gravity system. Whatever the type 

 of the boiler used, it should have capacity 

 to heat 5,500 square feet of radiation. 

 If a horizontal nibular boiler is selected, 

 one rated at sixty h(frse-power will be 

 about right. If you locate the boiler 

 on the surface and at the point men- 

 tioned it will be necessary to use a cir- 

 culating pump for hot water, and a 

 pump to return the water of condensa- 

 tion back to the boiler if steam is used. 



Each house requires about 1,650 square 

 feet of radiation, which can be supplied 

 by 1,400 lineal feet of 4-inch pipe; 1,650 

 lineal feet of 3-inch pipe; 2,640 feet of 

 2-inch pipe or 3,795 feet of 1^4 -inch 

 pipe. If you use steam each house 

 should have two 3-inch flow pipes and 

 eighteen I'/i-inch returns. L. C. C.

ELEVATION OF EXPANSION TANK. 



Which is the better way to feed a hot 

 water boiler, direct into the boiler or 

 into a return near the boiler? Would 

 it be a good plan to connect the 2-inch 

 feed pipe to a water ttink twenty-one 

 feet above the boiler, the tank six feet 

 high and ten feet ir. diameter? The 4- 

 inch heating pipes are connected by ce- 

 ment joints. What is the proper height 

 to place the tank above the boiler and 

 what size should it be. W. W. T. & S. 



I doubt if the cement joints of the 

 cast-iron "pipe will bear the pressure 

 from a tank elevated twenty-one feet. 

 If they will, this will greatly increase 

 the efficiency of your system. The feed 

 pipe, connected pyeierably to the main 

 return near the boiler, need be no more 

 than %-inch to care for the expansion 

 of a system of good size. The expan- 

 sion tank should be large enough to 

 hold all the water driven out of the sys- 

 tem by heating it. A 50-gallon tank is 

 sufficient for a boiler suitable for heat- 

 ing two houses 20x100. If wrought- 

 iron pipe with screw joints is used the 

 tank can be elevated fifteen to twenty 

 feet, but with cast-iron pipe and ce- 

 ment joints the tank must usually be 

 kept below ten feet. L. C. C.
