Greenhouse Heating. 



A MICHIQAN BANOE. 



I have two new houses, each 22^^x150 

 feet, five and one-half feet high at the 

 sides and eleven feet high to the ridge. 

 There arfe ground beds. Can I heat 

 these, two houses to a temperature of 50 

 •degrees when the outside temperature is 

 15 degrees below zero, using two 3-i.nch 

 flows on the purlins and six 2-inch re- 

 turns on the gutter posts, three on each 

 side? Where is the best place to put 

 the valves, on the flows or on the re- 

 turasf I will run the flows and returns 

 downhill. 



I also have a lean-to house, 16x72. 

 Can I heat it to 55 degrees by using 

 one 4-inch flow and five 2-inch returns? 

 My idea was to put the flow on the high 

 side wall, two returns on the purlin 

 and three returns under the outside 

 bench. J- Cr. 



While it would be possible to heat the 

 houses by using two 3-inch flows and 

 six 2-inch returns, it will be more e«o- 

 nomioal of fuel and require less atten- 

 tion if eight returns are used, and an 

 extra pipe should be used if there is 

 exposed glass in the side wall, as ap- 

 pears to be the case from the plan. 



In the leav-to house, 16x72 feet, use 

 one 3-inch flow and five 2-inch returns, 

 or six returns if the rear wall is ex- 

 posed. 



One valve would answer and this 

 should be at the most convenient point. 



A NEW JERSEY QUERY. 



Enclosed find a rough sketch of a 

 greenhouse 24x120 feet. Have you any 

 sketches of the manner in which a 

 house like this should be piped for hot 

 water heat, or can you make one? 

 Have you data on this subject? If so, 

 would be pleased to hear from you. 

 We would like to have some ideas. 



A. & P. 



The sketch shows a house 24x120 

 feet, with about two feet of glass in 

 each wall, and with a raised bench on 

 each side. The temperature desired 

 is not stated, but for 60 degrees it 

 will answer if three 2% -inch flow pipes 

 and eleven 2-inch returns are used. 

 Place one flow on each wall plate and 

 the other under the ridge. Three of the 

 returns should be on each wall, under 

 the flow pipe, and the others should be 

 distributed under the benches. 



A 4-inch main flow pipe will be re- 

 quired. This should rise from the 

 boiler to a point about one foot below 

 the level of the ridge. Connect the

 should run through the house at a

THREE CONNECTED HOUSES. 



I am. enclosing a diagram of my 

 greenhouse, which is 125 feet long and 

 has a total width of forty-two feet. 

 The house runs east and west. There 

 is glass in the gables. The south wall 

 is concrete and is three feet high. The 

 north side of the house is in the form 

 of a lean-to, with a boarded outside 

 wall. The west end will be protected 

 by the boiler shed. How many runs of 

 3-ineh pipe will be required to heat 



this house to 60 degrees in zero weath- 

 er? How large a boiler will be needed?' 

 I want a boiler large enough so that I 

 can add more glass. I am located im 

 western Illinois. S. R. 



To heat a greenhouse 42x125 feet to- 

 60 degrees in zero weather, seventeen 

 or eighteen 3-inch pipes should be used. 

 The plan shows the house to be di- 

 vided lengthwise into three parts. In 

 the widest portion, which appears to be 

 about twenty-one feet in width, three 

 3-inch flows and six returns of the same 

 size could be used. For the middle 

 part, which has a width of sixteen 

 feet, two flows and four returns can be- 

 used to advantage. In the 5-foot lean- 

 to one flow and one return will suffice.-
