By using all of the present pipes as 

 returns, and running two 2%-inch 

 flows overhead, but with a slight fall, 

 to the farther end of the house, where 

 each 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, 

 according 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. 



FAST OF FIFING INEFFECTIVE. 



Will your heating expert help me 

 solve the following problem? I have 

 three houses, each 22% 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 lO-section, cast-iron boiler, five and 

 one-half feet long, four and one-half 

 feet high and three feet wide, with a 

 firebox 18 x 42 inches. 



I heat the north house and half of 

 the middle house with one boiler, the 

 rest with the other boiler. The north 

 boiler has a 4-inch flow until it reaches 

 the house, then two 3Tioch flows to the 

 far end, dropping down and coming 

 back in coils under the benche£ The 

 returns have about one foot of ful, 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-ineh 

 pipe. This boiler is extremely, slow 

 acting. 



The south boiler has a 3-ineh flew 

 until it reaches the house an d hag three 

 2-inch flows overhead, droplMMp down 

 to coils in the wall ^d entmng the 

 boiler at two 2-inch openings. Half 

 of the returns are below the top of
