INSUFHCHENT RADIATION. 



I have a greenhouse 23x43 feet and 

 twelve feet to the ridge. It is located 

 in Illinois. I use a Wilks No. 20 hot 

 water boiler. I have one 3 -inch flow pipe 

 from the boiler and ten 2-inch returns, 

 all connected with one 2-inch return run- 

 ning into the boiler. The length of the 

 hot water pipes in the greenhouse is 

 forty feet. They are under the benches. 

 The boiler is four feet underground and 

 four feet lower than the returns. My 

 expansion tank is thirteen feet higher 

 than the boiler and three feet higher 

 than the highest hot water point. 



In cold weather I can only hold the 

 heat in my greenhouse to about 52 de- 

 grees above zero. I want to add one 

 more 2 -inch return into the boiler, or I 

 could add two more if needed. Would 

 I thus have better service from my hot 

 water pipes? Where is my trouble! I 

 am a beginner and did my own plumb- 

 ing, as we had no plumber here. 



E. T. O. 



Tour trouble is mainly inadequate 

 radiation. If you had fifteen 2-inch re- 

 turns you would have about the right 

 amount of radiation for roses. Twelve 

 pipes will answer for carnations and 

 lettuce. Your plan seems to be all right, 

 but you do not say that the expansion 

 tank is connected to the main return 

 close to the boiler. It should be, and 

 should be elevated six to ten feet more 

 than at present. It would be better if 

 the return were the same size as the flow 

 for hot water. L. C. C. 



PIPING IN OHIO. 



What would be the best method of 

 heating a greenhouse 27x200, running 

 east and west, with walls seven feet high, 

 three feet of glass in the north wall and 

 five feet in the south wall! There will be 

 no benches. I want a temperature of 50 

 degrees when the outside temperature is 

 15 degrees below zero. Would it be bet- 

 ter to locate the boiler in the center of 

 the house on the north side, or at the 

 northeast corner? I expect to grow 

 chrysanthemums, lettuce, etc., at present, 

 but hope to try carnations later and add

**Detroit" Traps will keep entire eystem free from water at all times, making 

 every foot of heating surface hot and efficient, returning automatically all water of 



condensation directly into the boiler — hot— 

 and without a pump or injector.

An economical boiler feeder.

 It will pay you.

 night-firing at first. 



Would hot water be better than steam? 

 Kindly state both methods, giving the 

 size and number of pipes for each sys- 

 tem. Can hot water be used where the 

 boiler is on top of the ground t If not, 

 what is the lowest type of practical 

 boiler for hot water and about what 

 price? Please give details of piping, so 

 I can direct the work myself.

My preference would be to establish 

 the nucleus of a central heating plant, 

 if I contemplated adding to the plant. 

 While steam will require more attention 

 and a little more night firing, I should

 can, with proper traps and circulating 

 pumps, work either steam or hot water 

 boilers above ground. If you decide to 

 use hot water, it would be preferable to 

 locate the heating plant 100 feet from
