Greenhouse Heating. 



FROM HOT WATER TO STEAM. 



As we contemplate building more 

 greenhouses and will necessarily have 

 to increase our heating capacity, we 

 have decided to change from hot water 

 to steam, so that one chimney and one 

 boiler may do the work for the plant. 



We have at present three houses, each 

 28x100 and six feet to the gutters. They 

 run east and west. At the east end of 

 the north house there is a brick office, 

 and at the west end of two houses is 

 the work shed. "We have a Kroeschell 

 boiler, with three openings in the top, 

 from which 4-inch flows are taken, one 

 for each house. These rise to the high- 

 est point in each house and flow the 

 length of the house on the north side; 

 then they branch and return under each 

 bench through twenty-one l^^-inch re- 

 turns, except in the south house, which 

 has twenty-three returns. We wish to 

 know what are the necessary changes in 

 piping, etc. 



The intended addition will consist of 

 one house, 18x100, north of the present 

 building, and another house, 20x100. 

 The north house will have a solid board 

 wall on the north side; the south house 

 will have three feet of glass in the 

 south side. We wish to maintain a tem- 

 perature of 60 degrees when the weather 

 is 22 degrees below zero. We are lo- 

 cated in southern Nebraska. H. L. H. 



If the present heating system is to be 

 used, the temperature desired can be 

 maintained with steam by using twelve 

 li/^-inch pipes in the three 28-foot 

 houses, where they have no exposed 

 walls. Two additional pipes will be de- 

 sirable for each exposed 6-foot wall. In 

 the new house, use one 2-inch overhead 

 flow and seven l^^-inch returns in the 

 18-foot house and ten returns in the 

 20-foot house. 



Instead of keeping the 4-inch over- 

 head flows in the 28-foot houses, it 

 would be better to take them out and 

 substitute one 2^4 -inch flow in each 

 house. 



GREENHOUSES AND DWELLING. 



I am sending you a sketch of my 

 greenhouses and should like to know 

 whether the system of piping there in- 

 dicated would be the best for the pur- 

 {)ose, and whether the boiler I have is 

 arge enough. I am heating the three 

 short houses and wish to add the long 

 house and also my dwelling house, which 

 contains eight rooms. The boiler I am 

 using is a fire-box boiler, eight feet long,

with a 32-inch shell and forty 2-inch 

 flues, each five feet long. The fire grate 

 is 2x3 feet. The boiler is tapped for one 

 4-inch main. 



All are connected houses, except that 

 the west house is separated from the 

 others by a glass partition, as I wish to 

 carry a temperature of 65 degrees in 

 that house and 50 degrees in the others. 

 The outside temperature here, in central 

 Michigan, sometimes drops to 20 degrees 

 below zero. C. A. H.
