Greeahonse Heating. 



PIPING IN NEBRASKA. 



We are planning a greenhouse 25x75 

 feet, running east and west. The north 

 wall will be five feet high, made of con- 

 crete. The south wall will be five feet 

 high, with two feet of glass. The height 

 to the ridge will be twelve feet. -There 

 will be a building at each end. We 

 shall heat with hot water. With a tem- 

 perature of 20 degrees below zero out- 

 side, how many 2-inch pipes will be re- 

 quired to maintain 55 degrees? Will 

 the same results be obtained by placing 

 five or six pipes against the north wall 

 and the balance under the bench, or will 

 the circulation be better if all are placed 

 under the benches! What size of boiler 

 will be required! I can buy a second- 

 hand horizontal tubular boiler. Can it 

 be fired as cheaply as the caat-iron 

 boilers! L. M. B. 



The house in question can be heated 

 by using sixteen 2-inch returns, sup- 

 plied by two 3 -inch flows, one to each 

 eight returns. If the requirements of 

 the plants to be grown will be satisfied 

 as well by wall pipes as by those under 

 the bench, you may use your own discre- 

 tion regarding the location of the pipes. 

 With most crops, save lettuce, bottom 

 heat is to be preferred. To heat the 

 plant you should have a boiler rated for 

 not less than 1,200 square feet of radia- 

 tion. A horizontal, return-tube boiler is 

 one of the most economical types and the 

 best greenhouse steel and cast-iron boil- 

 ers are designed to secure as far as 

 possible the economy of the horizontal, 

 return tubular boiler. This does not ap- 

 ply to the locomotive type of boiler.

PIPING IN MISSOUHL 



T wish to heat, with hot water, two 

 houses, one 20x56, the other 20x66, run- 

 ning east and west. The side walls are 

 to be six feet high, the north wall be- 

 ing boarded up. The south wall is to 

 have five fe^t six inches of glass. The 

 house will measure twelve feet to the 

 ridge, with glass in three gable ends, 

 the fourth end being protected by the 

 boiler shed. How many 2-inch flows 

 and l^^-inch returns will be required to 

 keep the south house, the 66-foot one, 

 at 65 to 70 degrees, and the north house, 

 the 56-foot one, at 50 to 55 degrees, in 

 zero weather! Or would it be more

is acknowledged the best for the 

 florist because it is durable, and does 

 its work without trouble and annoy- 

 ance, saving its cost by the economy 

 in coal bills.
