cated at the highest point in the system, 

 Avhich should be just over the boiler; 

 from this point the pipes should have a 

 gradual fall of about one inch to every 

 ten feet of their length, finally termi- 

 nating in a vertical drop and all connect- 

 ing into the bottom of the boiler. The 

 flow pipe for each house should be pro- 

 vided with a gate valve to check the flow 

 of water in case it is desired to run one 

 house cool and the other warm. One 

 valve to each house will be sufficient. 



The first cost of the piping for steam 

 will be less than for hot water, but under 

 your conditions steam would be imprac- 

 tical on account of the position in which 

 your boiler must be set. L. C. C. 



PIPING FOR MINNESOTA. 



I expect to build a house 20x60 feet. 

 "Would the following system of water 

 heating be satisfactory in Minnesota, 

 where the temperature sometimes reaches 

 30 degrees below zero? The boiler will be 

 at the west end. The system would consist 

 of one 4-inch flow pipe from the dome of 

 the boiler, rising to the top of the door 

 at the extreme end and branching into 

 fourteen l^^-inch return pipes which run 

 under the benches. The end of the house 

 nearest the boiler is to be warmer, and 

 in order to secure this greater warmth 

 I have planned to have four of the pipes 

 branch at this end of the house, which 

 would be separated from the rest of the 

 house by a partition. Would one flow 

 pipe supply these returns, or are there 

 too many of them? If there should be 

 more flow pipes, where should they be? 

 And if this plan is not right, what would 

 you suggest? The wall is eight feet on 

 the north, with no glass, and six feet on 

 the south, with two feet of glass. Are 

 thesQ sizes of pipes all right? 



N. N. C. 



The plan of piping suggested will pro- 

 vide sufficient heat for carnations, chrys- 

 anthemums and similar plants, but for 

 roses it would be desirable to increase 

 the number of 2-inch pipes to eighteen. 

 The 4-inch flow pipe will supply the four- 

 teen 2-inch returns, but no more. As 

 the water will be considerably cooled by 

 the time it returns to where the extra 

 pipes branch off, they will add little to 

 the warmth of this section and this part 

 of the house will be inclined to be cool- 

 est. A better plan would be to insert a 

 tee in the 4-inch flow pipe just before 

 the partition is reached and connect di- 

 rectly to the extra return pipes below 

 the benches. This connecting pipe, how- 

 ever, should be provided with a gate

THHEE CONNECTED HOUSES. 



I should like to get a little informa- 

 tion in regard to greenhouse heating. I 

 had a boiler put in last fall for hot 

 water. My houses are one 18-foot house 

 in center, with a 10-foot house on each 

 side, running north and south, with a 

 shed at each end. The boiler is in a pit 

 at the north end, with its top two feet 

 below the greenhouse floor. A 4-inch 

 pipe feeds a header under the outside 

 bench in each outside (10-foot) house. 

 Each header feeds four 2-ineh pipes run- 

 ning under the outside bench to the south 

 end, where one of these 2-inch pipes is 

 carried through to the center house and 

 returns through it. The other three 2-inch

pipes return under the inside bench of 

 each 10-foot house, joining at the north 

 end in a 4-inch pipe going down to the 

 bottom of the boiler. This gives four 

 flows and three returns in each 10-foot 

 house and four flows and six returns in 

 the center house. There is an expansion 

 tank at the south end, holding thirty 

 gallons. Now, each house heats about 

 equally well, but is from 10 to 15 de- 

 grees warmer at the north end than at 

 the south end. How can I change the 

 system so as to make it heat more evenly f
