Qreeahoase Heating. 



HOT WATER FOR LONG HOUSE. 



What is the greatest length of green- 

 houses that can be properly heated with 

 hot water, using 2-inch wrought iron pipe 

 as radiation? I have now in operation 

 one house, 38x200, heated with 2-inch 

 hot water pipe, using eight 2-inch flows 

 and eight 2-inch returns. \ should Uke 

 to add another 200 feet to this, making a 

 house 400 feet long, heated from one 

 end, as I am unable to heat both ways 

 from the middle. My idea is that I have 

 reached nearly the maximum to get the 

 proper benefit out of my radiation. One 

 man tells me to use two 5-inch flows out 

 through the middle of the 400-foot house 

 and return with sixteen 2-inch pipes as 

 radiation, and I think he is pretty nearly 

 right. Now, I should like to have your 

 advice in the matter, giving the proper 

 economical length of houses on both 

 plans of heating. "We use the open sys- 

 tem, but have our expansion tank up 

 thirty feet from the boiler. E. W. K. 



Even with your high expansion tank, I 

 do not think it wise to double the length 

 of your present heating system. The 

 use of the mains suggested would un- 

 doubtedly come as near solving the prob- 

 lem as it is possible to solve it without 

 the use of a circulating pump. We do 

 not advocate hot water nins of more than 

 100 feet under ordinary conditions, and 

 I doubt if you would have the success 

 you enjoy in your 200-foot houses if 

 you did not have the expansion tank 

 thirty feet in the air. L. C. C. 



PIPING IN OHIO. 



I have a house 29x44x10, and five feet 

 to the plate, with no glass in the sides, 

 but with the south end half glass. The 

 house runs north and south. I have the 

 furnace in a shed at the north end, built 

 in the ground, and a 10-inch smoke flue 

 running through the center to the south 

 end and out. Now, in the furnace I have 

 100 feet of 1-inch pipe, which connects 

 to a 2-inch flow, which runs to the south

Steam Traps 



iffiSonomy Fof StcaiTi Hcatecl Greenhouses 



**DetFoit** Traps will keep entire eyetem 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. 



A great coal saver. 



An economical boiler feeder. 



Worth double the price. 



Ask Mr. Geo. Reinberg, flo- 

 rist, Chicago, 111. He has 

 used other maizes, also. 



Write us size of boiler and number of square feet of glasB in your greenhouse. 

 It will pay you.

 give me all the heat I need, but I wish 

 to take out the flue and put in a boiler.
