By nsin? all of the present pipes as 

 ?ttuin'-. iiinl rnnninp two 2V-;-inch 

 flows overhead, but with a slight fall, 

 to the farther end of the house, where 

 ■ ach should be connected with the four 

 pipes on one side of the house, a tem- 

 perature of 50 degrees can be obtained. 

 One 3-inch flow and one 3-inch return 

 can be run to each house and con- 

 nected with the pipe just specified. 

 While only 600 square feet of radia- 

 tion will be used, it will be well to 

 use a boiler rated at about 1,000 square 

 feet. 



To heat a dwelling 30x30 feet would 

 vequire from 300 to 500 feet additional, 

 -iccording to the thoroughness with 

 which it is heated. There should be no 

 difficulty about heating the dwelling 

 from the greenhouse boiler if one of 



sufficient capacity is installed, and it 

 will give great economy in fuel and 

 labor. 



PART OF PIPING INEFFECTIVE, 



Will your heating expert help me 

 solve the follow iiig problem? T have 

 three houses, each -•2'j x 100 feet, run- 

 ning east and west. At the east end 

 of the north house there is a boiler, 

 in a pit seven feet deep. It is a hori- 

 zontal, tubular boiler, ten feet long and 

 thirty-six inches wide, with a firebox 

 thirty-six inches square. At the east 

 end of the south house there is another 

 boiler, in a 3-foot pit. This one is 

 a 10-section, cast-iron boiler, five and 

 one-half feet long, four and one-half 

 feet high and three feet wide, with a 

 tirebox lSx42 inches. 



I heat the north house and half of 

 the middle house with one boiler, thf 

 rest with the other boiler. The north 

 l)oiIer has a 4-inch flow until it reaches 

 the house, then two 3-inch flows to the 

 far end, dropping down and coming 

 back in coils under the benches. The 

 rrturns have about one foot of fall, and 

 when they reach the boiler are still 

 above the top; they drop down along 

 side the boiler to the bottom, with 4 

 inch returns. The coils are of 2-inch 

 pijie. This boiler is extremely oIott 

 acting. 



The south boiler has a 3-inch flow 

 until it reaches the house and has three 

 2-inch flows overhead, dropping down 

 to coils in the wall and entering the 

 boiler at two 2-inch openings. Half 

 tif the returns are below the top of
