HEATING VITH A FLUE. 



We are contemplating building a 

 small greenhouse, about 20x20. Can we 

 successfully heat it, when the mercury 

 falls to 20 and 25 degrees below zero, 

 with a horizontal flue, the length of 

 whicii would be seventy-five feet? What 

 provision should there be for cleaning 

 out the flue whenever necessary! What 

 size should the flue and furnace bef 

 We are located in Nebraska. G. H. P. 



I would not advise the use of a flue in 

 a house of these dimensions in your cli- 

 mate, unless the house was intended 

 merely to bring on plants in the spring 

 in much the same way as a hotbed.

PIPING IN MICHIGAN. 



I am erecting a greenhouse 25x150 

 feet and twelve feet eight inches to the 

 ridge. The height of the walls is six 

 feet, with three feet of glass in each 

 wall. One gable end is glass. The house 

 has an even-span roof and runs east and 

 west, with the boiler shed attached to 

 the east end. I wish to heat it with 

 hot water and should be pleased if you 

 would give me the best plan for pip- 

 ing it. 



I have a thirty-five horse-power loco- 

 motive type of boiler, with one 6-inch 

 opening in the top and two 4-inch open- 

 ings at the bottom. The top of the 

 boiler is three feet below the surface of 

 the ground. I wish to heat the house 

 to 60 degrees in zero weather. I wish 

 to use as small pipe in coils as possible. 

 Would it be a good plan to break up 

 the coils into lengths of fifty feet? 



C. S. B. 



The only way I can devise by which 

 to shorten the length of the flow and 

 return pipes in your house would be to 

 place the boiler seventy-five feet from 

 the ends and carry the pipes in either 

 direction to the ends of the house, ar- 

 ranging the returns across the middle. 

 As you have located the boiler, nothing 

 can be gained by dividing the coils into 

 50-foot lengths, unless you desire to par- 

 tition the house into three rooms. If 

 you wish to use it as a single house, it 

 wiU be as well to use two 3-inch flow 

 pipes from the boiler to the far end of
