PIPES IN CORRECT NUMBER. 



I plan to build a greenhouse 24x50 

 feet, with three feet of glass and three 

 feet of concrete. It will be six feet from 

 grade to plate and thirteen feet to the 

 ridge. There will be glass in one gable 

 end. 



To heat the house to 65 degrees when 

 it is 20 degrees below zero outside, will 

 one 2-inch main under the ridge, four 

 114-iiich returns under each side bench 

 and three ly^-inch. returns under two 

 center benches suffice? I should be 

 pleased to receive suggestions on this 

 matter. C. L. S. — 111. 



The radiation suggested will be en- 

 tirely satisfactory for a house 24x50 

 feet, with three feet of glass in the side 

 walls, to be heated to 60 degrees in zero 

 weather, with low-pressure steam. With 

 a boiler of good size, carrying five 

 pounds of pressure, this radiation might 

 be used for 65 degrees, in weather 20 

 degrees below zero, if the cold periods 

 are of short duration and are infrequent, 

 but it would be advisable to use a 21^- 

 inch overhead flow pipe and to put an 

 additional return in each coil. 



If the water level of the boiler is three 

 feet below the returns, it will make but 

 little difference how the flows and re- 

 turns are arranged, although it is best 

 to have the flow overhead and the re- 

 turns under the benches or on the side 

 walls. However, the coils may serve as 

 coils with the drip returning in a main 

 underneath, or there may be a flow
