culation? Where should the air valves 

 be placed? The piping consists of a 

 2-inch overhead feed pipe in the center 

 of the house, and returns under the 

 side benches. At the north side there 

 are two lV4-inch returns and one 2-inch 

 return; at the south side there is one 

 radiator containing three 1-inch pipes. 

 I shall greatly appreciate any informa- 

 tion, as I am tired of experimenting. 

 I am located in southeastern Michigan.

It is always desirable to have a steam 

 boiler two feet below the coils, when a 

 gravity system is used, and for a large 

 range the difference in height should 

 be even more than two feet. The air 

 valves should be near the lower end of 

 each of the coils. While the boiler in 

 question would probably test about five 

 horse-power, the grate is rather small 

 for greenhouse heating, where it is de- 

 sirable to leave the fire for several 

 hours at night. The trouble referred 

 to could probably be corrected by sink- 

 ing the boiler about two feet. If this 

 can not be done, a check valve could 

 be placed in the return and the water 

 supplied to the boiler by means of an 

 electric pump. 



For a house requiring only 300 square 

 feet of steam radiation it is generally 

 more satisfactory to use hot water, but 

 the same difficulty would be met with 

 unless the boiler can be lowered. While, 

 as a rule, it is advisable to have chim- 

 neys at least twenty-five feet high, if 

 a good draft can be secured with a 

 height of eighteen feet, that is all that 

 is required. The amount of radiation 

 is fairly correct, although another 1^- 

 inch return could be used to advantage 

 along the south side of the house.
