HEATING LETYuCE HOUSE. 



I am adding a new house to my plant, 

 12x90 feet, with 4-foot walls and a 10- 

 foot ridge. The north wall is boarded, 

 south wall of glass to the ground. My 

 boiler-shed adjoins it on the east. I 

 want to grow lettuce, and need 45 to 50 

 degrees in winter. Our coldest weather 

 is 10 degrees below zero, but it rarely 

 goes below zero. There is a hill to the 

 north, which protects the house some. I 

 want to use 1^4 -inch pipe, with steam, 

 and no steam trap. This house has no 

 benches. 



Can you tell me of anything to re- 

 pair a leaky house with, without remov- 

 ing the glass. C. F. B. 



To heat your house 12x90 feet with 

 low pressure steam, using 1*4 -inch pipe 

 for returns, it will be necessary to pro- 

 vide a 2-inch flow under the ridge and 

 two manifolds of four pipes each on the 

 side walls, the full length of the house. 

 This makes a 2-inch riser and eight 1^- 

 inch returns, arranged in two coils of 

 four pipes each on the side walls. 



The leaky house, if glazed with lapped 

 glass, can be repaired without removing 

 the glass by the use of liquid putty, i. e., 

 putty thinned with boiled oil and applied 

 with a putty bulb. There are several 

 patented materials upon the market as 

 well as several devices for applying 

 same, all of which are quite satisfactory.

PIPING FOR THREE HOUSES. 



Will you please tell me how best to 

 arrange the piping to heat three green- 

 houses running north and south side by 

 side, with 4-foot concrete walls and nine 

 feet ten inches to the ridges f Two of 

 them are each 18x74, soUd concrete beds, 

 and the other is 18x52, raised beds. The 

 piping is wanted under the beds in the 

 short house. My boiler has 5-inch flow 

 and 4-inch return openings, and the bot- 

 tom of the boiler-room is five feet ten 

 inches below the beds in the houses. 

 I want to use 2-inch pipe coils, and 

 want a temperature of 60 degrees. 



A. S. 



Each house in the range can be heated 

 by eleven runs of 2-inch pipe the length 

 of the house. If two pipes in each house 

 are used for flows, the others may be 

 arranged either on the side walls or un- 

 der the benches as returns. The flows 

 can be carried either on the side walls 

 near the gutters, or under the roof near 

 the purlins or ridge, as preferred. The 

 pipes should be so arranged as to give 

 a little more heat near exposed walls 

 than near protected ones. L. C. C. 



HEATING BLOCK OF HOUSES. 



Please give us some information and 

 advice regarding heating. We have a 

 sectional hot water boiler, nine sections 

 long, which heats our old range. We 

 are building three even-span, ridge-and- 

 furrow carnation houses in a block, the 

 block being 100 feet long and forty- 

 seven feet wide, seven and one-half feet 

 to gutters, one row of vents to each 

 house, thirty-two inches of glass in sides 

 and same at ends. Would it be best 

 to heat the new houses with water or 

 steam f We are inclined to prefer a
