turn mains, wliich we run into a 5-inch 

 main flow, feeding the two houses, and 

 5-inch return, respectively. The 5-inch 

 return is reduced to a 4-inch pipe when 

 it passes into the second house. The 

 boiler burns soft coal, but hard coal 

 could be used in severely cold weather. 

 Can you tell us what pipe will be neces- 

 sary to extend the arrangement already 

 in operation into the third house and 

 whether or not the main flow and return 

 pipes will have to be changed? Will 

 this boiler, which is rated at 2,600 feet 

 of radiation, be Irrrge enough? 



E. J. W. & S.— N. y. 



As nearly as can be estimated from the 

 above statement, about 1,200 square feet 

 of radiation are now in use, including 

 the main flow and return pipe. Accept- 

 ing the figuros given as trustworthy, it 

 would be inadvisable to add much more 

 radiation if soft coal is to be used, but 

 it would be reasonably safe to add from 

 400 to 500 additional feet to the system 

 with hard coal as the fuel. 



The house which it is proposed to 

 build will require not far from 800 

 square feet of hot water radiation if 55 

 degrees is to be maintained. This would 

 still be below the rating of the boiler 

 and, presuming thit the rating is cor- 

 rect, it is possible that the temperatures 

 desired could be maintained in the three 

 houses if the outside temperature does 

 not drop below zero, if careful attention 

 is given to the firing and liard coal is 

 used. , 



Eun a separate 4-inch main to the new 

 house, with a return of the same size, 

 if this can be done without too much 

 expense. Tlio present mains, however, 

 are fairly well adapted to the capacity 

 t)f tlie boiler. To heat the new house, 

 use three 2VL>-iiich overhead flow pipes, 

 one on each side wall plate and the other 

 two feet below the ridge. For the re- 

 turns, put in three coils with ten 2-inch 

 pipes, placing four yiipcs in the coil 

 along the exposed wall. 



In heating the tank use about twelve 

 feet of 1-inoh pip"e for the roil, if steam 

 heat is used, placing this below tlie cus- 

 tomary water level, or the same amount 

 of 2-inch pipe if hftt water heat is used. 

 Just how tlie coils sliould be arranged 

 inside the tank would depend upon the 

 shape and dimensions of the tank. Of 

 course, the hot water pipe should be con- 

 nected with a flow and a return pipe, 

 and provision should be made for dispos- 

 ing of the drip from the steam pipe. 



Des Moines, la. — A greenhouse will be 

 opened by Gurley & Anderson in April, 

 with J, W. Anderson as the manager.
