answer for 5,000 square feet, it will 

 be better, exceiJt under the most favor- 

 able conditions, to use 7-inch pipes, or 

 perhaps two 5-inch pipes. 



A temperature of 80 to 85 degrees 

 is seldom required, and it is probable 

 that one square foot of pipe to two 

 square feet of glass, which would give 

 a temperature of 75 degrees when the 

 mercury drops to 15 degrees below 

 zero outside, would suffice for every 

 l»urj»ose. 



GREENHOUSE AND COIDFRAMES. 



I have built a new boiler room and 

 should like to get a little information. 

 From the top of the boiler, which is of 

 the square, sectional hot water type, 

 a 3^^-inch riser extends up to a height 

 of five feet, where a 3-inch flow is taken 

 into the greenhouse. At the highest 

 point a %-inch pipe goes up to the 

 expansion tank. The flow pipe is about 

 eight feet above the inlet to the boiler. 

 Now I want to put in a second 3 1,4 -inch 

 riser, from which a 3-iuch flow will be 

 taken to heat some coldframes outside. 

 Should this riser be five feet high also, 

 or can the flow be taken off at a height 

 of four feet and connected with the

expansion tank as the first one is? The 

 tank has been above the roof on the 

 outside, but I want to place it inside, 

 where it would only be twelve inches 

 above the flow pipes. Would this dis- 

 tance be sufficient? Can I use the stand- 

 ard globe valves, which I have, on 



the flows and returns, or should they 

 be the full-opening gate valves? I 

 may want to cut off part or all of the 

 flow to the frames at times.
