Greenhouse Heating. 



AT THE NOETH PACIFIC COAST. 



Which is the better way to run the 

 flow pipes, uphill or downhill? How 

 can I arrange the piping, both flows 

 and returns, so as to get the best re- 

 sults in my range of five greenhouses, 

 here in the west part of Washington 

 state? As you will see from the dia- 

 gram which I enclose, the houses all 

 run parallel, with the boiler at one end. 



N. H. 



It is generally best to run the flow 

 pipes downhill, giving them just fall 

 enough to keep the air from pocketing. 



The sketch shows three houses 136 

 feet long, one of them nine feet wide 

 and the other two each twenty-two and 

 one-half feet wide; also two houses 

 23x100 feet. The inquirer, however, 

 does not state the temperature, either 

 inside or outside. To heat with hot 

 water to 60 degrees in the 9-foot house, 

 use two 214-inch pipes as flows and 

 four 2-inch pipes as returns. In the 

 other houses use three 214-inch flows 

 and ten 2-inch returns. For 50 degrees, 

 use eight returns. Carry one flow on 

 each plate and one under the ridge of 

 • the wide houses. 



PlPma A CABNATION HOUSE. 



I have one greenhouse, 18x80, lo- 

 cated in the southeastern part of the 

 state of Washington. Our main crop 

 will be carnations, though in winter we 

 shall have potted plants in bloom as 

 the season comes along. What temper-

ature will be required for such stock? 

 I have an Ideal boiler. Please tell me 

 the best way to pipe the house, for 

 hot water. I will tell you my idea: 

 Start with two 3-inch pipes from the 

 boiler into the greenhouse; then reduce 

 to 2%-inch. If I use IV^-inch returns, 

 how many returns will be needed, with 

 two 214-inch flows. H. & H. 



The temperature for a greenhouse in 

 which carnations are to form the lead- 

 ing crop should be 55 degrees or a lit- 

 tle less, depending considerably upon 

 the variety. This, of course, refers to 

 the temperature to be maintained at 

 night, as during the day it should be 

 somewhat warmer, if proper ventila- 

 tion is given. 



To heat a house 18x80 feet to 55 de- 

 grees, about 500 square feet of radia- 

 tion would be required in the climate 

 of Seattle, and 600 feet and upward in 

 the cooler parts of the country. To 

 provide this radiation, two 2% -inch
