Greenhouse Heating. 



OIJ> QAS PIPE FOB HEATTNG. 



I shall appreciate it greatly if you 

 will give me some information. Would 

 you advise me to use, for hot water 

 heating in the greenhouse, pipe that . 

 has been used as gas pipe! Do you 

 think it would cause an odor in the 

 houses and, if so, do you think this 

 would be injurious to the plants? 



G. C. S. 



So far as any likelihood of injury to 

 the plants is concerned, I would not 

 hesitate to use the pipe referred to, 

 since, if there is any tar or similar sub- 

 stance on the outside of the pipe, it 

 may be easily burned off. However, it 

 will be necessary to be absolutely sure 

 that the inside of the pipe is free from 

 tar, for if there is any considerable 

 amount of deposit it will hinder the 

 circulation, while even a slight coating 

 would lessen the amount of heat 

 radiated by the pipe. I have known of 

 cases where gas pipe has been nearly 

 choked with tar. If the pipe is much 

 rusted, this also would check radia- 

 tion. 



SIZE AND SLANT OF PIPES. 



I am building a greenhouse, 28x100. 

 The side walls will be six and one-half 

 feet high and will contain three feet of 

 concrete and three and one-half feet of 

 glass. The east end will be glass; the 

 west end will be attached to the service 

 building. The ridge will be thirteen 

 feet nine inches high. I shall use about 

 1,760 feet of 2-inch pipes, arranging 

 them along the side walls, below the 

 glass, as shown in the enclosed diagram. 

 There will be four 2-inch flows and four 

 2-inch returns along each side wall and 

 along the east end wall to the door in 

 the center. The boiler will be placed 

 in a pit. What temperature could I 

 maintain with such piping, when the 

 outside temperature is 15 degrees below 

 zerof My location, you will notice, is 

 southern Pennsylvania. Would you ar- 

 range the piping for this house any dif- 

 ferently, and whyf 



This house will have side ventilation 

 and one row of ventilators at the ridge. 

 They will be hinged at the ridge. The 

 house will run east and west. On which 

 side of the ridge would it be better to 

 put the ventilators, north or south!

The amount of pipe mentioned is 

 about what I would use in a greenhouse 

 28x100, with three and one-half feet o£ 

 glass in each side wall, if I wished a

 Standard Thermometer Co., Boston. 



Dear Sirs: Enclosed please find 

 check, for which please send us at 

 once one $10 thermostat with lock and 

 key. We put up two of your thermo- 

 stats in November, and thanks to them 

 for working last night. Our night 

 fireman, who has worked for us on the 

 same job for 6 years, went to sleep and 

 the bell rang about 3 o'clock. The 

 houses were down to 35° before we got 

 steam into them. If they had frozen 

 up, we would have lost about $36,000. 

 Another year we hope to have a ther- 

 mostat in every one of our 14 houses. 



Respectfully, Bekrd Bros.
