Greenhouse Heating. 



HEAT FOB USTTUCE HOUSE. 



We wish to aslf you how to pipe our 

 greenhouse for steam heat. The house 

 is 20x100 feet. There are two feet ot 

 glass in the sides and the south end 

 is all glass. There are raised benches. 

 Can we use 1^-inch pipe? We want 

 to grow lettuce in the fall and winter, 

 and potted plants in spring and sum- 

 mer. We are located in northeastern 

 Ohio. L. A. E. & S. 



There will be no diflBculty about us- 

 ing 114-inch pipe for the coils and re- 

 turn pipes. The main feed pipe from 

 the boiler should be 2-inch. This pipe 

 should branch at the end of the house 

 into two l^^-inch pipes to connect with 

 the coils, of which there should be one 

 on each side wall, with five 1%-inch 

 pipes in each. These should run around 

 the south end to the center, or to the 

 door if there is one. The coils should 

 be given a slight fall, and from the 

 end of each there should be a connec- 

 tion with a 1^-inch pipe to carry the 

 drip back to the boiler. There should 

 be an air cock in the end of each coil. 

 This piping should give a temperature 

 of 50 to 55 degrees in zero weather. 



DOES NOT HEAT EVENLY. 



At present we have one greenhouse, 

 running east and west. We expect to 

 extend this house and also to build an- 

 other house, parallel with the present 

 one, but detached from it. No. 1 is 

 the present greenhouse, a carnation 

 house, erected in 1909. It is 42x150 

 feet, seven feet high to the eaves and 

 eighteen feet to the ridge, with three 

 feet of glass in each side and glass 

 ends. This house does not heat evenly, 

 but has a temperature of 50 degrees 

 near the boiler and 60 degrees at the 

 opposite end. It contains twenty-eight 

 2-inch pipes, six of them under each of 

 the outside bedd and four under each 

 of the other four beds. The water is 

 carried to the far end by one 4-inch 

 overhead flow, which is highest just 

 over the boiler and is connected at the 

 far end with manifolds under the beds, 

 for the 2-inch returns. How can we 

 make the system heat more evenly! 

 We want a temperature of 50 to 55 

 degrees throughout the house, as we 

 grow only carnations in it. 



House No. 2 is a proposed 100-foot 

 extension to house No. 1. It will be 

 built next year and will be used for 

 carnations. No. 3 is a proposed new 

 house for roses, parallel with No. 1, as 

 already stated, but not connected. It 

 will be 42x250, with walls of the same 

 height and the same construction as in 

 house No. 1. It will Require a tem- 

 perature of 55 to 65 degrees. It will 

 contain five beds, eacy six feet wide 

 and extending the full length of the 

 house except the walks at each end. 

 We wish to heat with 2-inch pipes un-

Dear Sir:— 



You ask to explain about the Morehead Traps. I am so well pleased 

 with them and don't see how I could get along without them. I have two 

 No. 3 Traps. My bouses are on the level, although 1 have just a little fall 

 to the receiver. My returns are 2-in. ; main, 4-in., 100 ft. ; 12,600 feet iU, 2200 

 ft. 2-ln. My boilers, one 60 and one 80 horse-power ; mr houses are 7 ft. to 

 gutter and I heat 60,000 square feet. I have never had any trouble with 

 keeping my houses warm since I had the Morehead Steam Trap. 



Best wishes, 



Youn truly. 



C. Krantz.

 Please tell us how to arrange the flows,

 At present we have one boiler, at 



the west end of house No. 1. It is an 

 old Ideal boiler, manufactured by the 

 American Radiator Co. We expect to 

 install a new ll-section Mills boiler

 houses, and to pipe this boiler so we-
