and returning in six 2-inch returns, 

 flowing thence into one 4-inch return 

 main. I have a large amount of 1-inch 

 pipe on hand which I should like to use 

 in making the coils for the small house. 

 The temperature to be maintained is 60 

 degrees, when the outside temperature 

 is 20 degrees below zero. Coal for night 

 firing and wood for day firing will be 

 used. Can you give me any advice in 

 regard to the arrangement of the piping 

 for the small house? Is the boiler 

 which I have described large enough 

 to meet the requirements? A. G. 



The length of the sashbars is not 

 given for the large house, and, as there 

 is no reference to the height of the 

 walls, it is impossible to make the com- 

 putation. The dimensions of the house, 

 however, are stated as 16x100 feet, 

 and it is twelve feet to the ridge. The 

 sashbars, therefore, must be approxi- 

 mately eleven feet long and the walls 

 about five feet high, with sixteen inches 

 of glass in the west wall. 



To heat this house to 60 degrees, 

 when the outside temperature is 20 

 degrees below zero, 1,000 square feet 

 of radiation will be required. To sup- 

 ply this requirement, three 2%-inch 

 flows and twelve 2 -inch returns should 

 be used. 



The other house is 10x100 feet, with 

 concrete walls projecting two feet 

 above the surface of the earth, and the 

 length of the sashbars is ten feet. To 

 heat this house will require about 800 

 square feet of radiation. It is inad- 

 visable to use 1-inch pipe in a house of 

 this length, but the suggestion to use 

 three 2%-inch flow and nine 2-inch re- 

 turn pipes is made. 



The boiler is large enough to heat 

 the two houses, but you should use a 

 4-inch main feed pipe to the 16x100- 

 foot house, or if one of the 2%-inch 

 flow pipes can be connected directly 

 with the boiler, in addition to the 3-inch 

 flow now in use, this will also answer 

 the purpose. 



Although it would be advl.iable to use 

 a 4-inch flow pipe for the lOxlOO-foot 

 liousc, a 3-inch flow and return would 

 give fairly good results. It will be 

 helpful if two 4-inch inlets can be 

 provided for the boiler, but if the main 

 returns are 4-inch and 3-inch respec- 

 tively, they may be joined at the boiler 

 and enter through the present 4-inch 

 opening.
