will answer to allow the temperature 

 to drop to 40 degrees in zero weather. 

 To heat them to 60 degrees, a sixteen 

 horse-power boiler would be desirable 

 and a boiler of twenty horse-power 

 would be still better. The boiler should 

 have two 2^/^ -inch flow connections and 

 two 2%-ineh return connections, but if 

 this can not be arranged, take off two 

 2^ -inch flow pipes, one to each house, 

 as near the boiler as possible, and carry 

 back a 2%-inch main return pipe from 

 each house to a point close to the boiler, 

 where they can be reduced to 2-inch 

 and connected with the 2-inch ports. 

 It would be even better if the larger 

 house could have two 2i^-inch flows 

 and two 2% -inch returns, connected di- 

 rectly with the boiler. 



BETUBN Apes are coud. 



I am having some trouble with the 

 heating of a new house, 18x42, three- 

 quarter span and twelve feet to the 

 ridge. The house runs east and west. 

 The south wall is four feet high and 

 contains two feet eif^glass. The north 

 wall adjoins another house and the 

 west wall adjoins the boiler house; the 

 east wall is without glass. My piping 

 is as follows: A 3-inch flow, rising 

 six and one-half feet straight up from 

 the boiler, which is at the north side 

 of the house, in a pit; then an elbow 

 and nine feet of pipe to the center of 

 the house; then another elbow, con- 

 necting with a flow which runs to the 

 east end of the house, three feet from 

 the ridge. At the east end I have a 

 3-inch tee and eighteen inches of 3-inch 

 pipe running each way; then a 3x2^^x2 

 tee; then a 2^^x2x2 teo and a 2-inch 

 elbow. This gives me six 2-inch re- 

 turns, three on each side wall. The 

 returns drop straight down three, three 

 and one-half and four feet, and then 

 run to the side walls and back to the 

 west end of the house, where they 

 come together with the same arrange- 

 ment of tees and pipe as at the other 

 end of the house, except that the pipes 

 on the south wall drop and run across 

 the house on the floor, to be out of the 

 way. All the pipes come together under 

 the north bench, about three feet from 

 the boiler, and connect with a 3-inch 

 pipe which runs two feet on a level and 

 then drops down to the bottom of the 

 boiler, into a 3-inch return opening. 



The trouble is as follows: The flow 

 pipe becomes quite hot, but the re- 

 turns scarcely heat any. All the pipes, 

 both flow and returns, run with a slight 

 fall. Can you tell me the reason for 

 the trouble? H. E. H.
