the main flow will be across the build- 

 ing from the north to the south, about 

 thirteen feet from the east end. 



What is the proper size of main flow 

 and branch flows, number and size of 

 coils, etc.? I should like to use l^-inch 

 and 2-inch pipe. What is the largest 

 capacity of hot water boiler that can be 

 successfully carried with my chimney. 

 What is the best method of ventilation 

 for one slope, top or bottom! On which 

 side should either be placed? 



C. R. D.— Ind. 



There was no mention of the temper- 

 ature to be maintained in the green- 

 house, but presumably 60 degrees will 

 be satisfactory. 



The main flow pipe, to supply the 

 radiation for the house 21x40 feet, 

 should be 3-inch. After carrying it to 

 a point directly under the ridge of the 

 house, extend it to the west end of the 

 house on a level two or three feet below 

 the ridge. Eun 2%-inch branch pipes 

 in each direction and take off 2-inch 

 feed pipes to supply coils of four 1%- 

 inch returns under each of the benches 

 in the middle of the house. Then re- 

 duce the branch feed pipes to 2-inch 

 and extend them to connect with coils 

 of four l^^-inch pipes under each of the 

 side benches. Run the return coils to 

 the east end of the house and connect 

 them with the main return pipe lead- 

 ing to the boiler. This should be 3-inch 

 after the last coil has been connected. 



The mains for the later addition 

 should also be 3-inch pipes and it will 

 require sixteen IVo-inch returns in the 

 coils. If both houses are to be heated 

 from one main flow pipe, it should be 

 4-inch. 



Economical results cannot be ex- 

 pected with more than 800 square feet 

 of radiation from a boiler connected 

 with an 8x8-inch flue and it is prefer- 

 able to limit the radiation to 600 square 

 feet for a boiler with a flue of the size 

 mentioned, especially when soft coal is 

 to be used. 



It is preferable to have ventilators 

 hinged at the ridge and if only one line 

 is used have them open away from the 

 prevailing strong winds. On houses 

 running north and south this places the 

 ventilators on the east side of the ridge 

 in the central and western states. If 

 the prevailing winds are from the 

 northwest, as in many sections, the ven- 

 tilators would be on the south side of 

 the ridge in houses running east and 

 west. They should be on the north side 

 if the prevailing winds are from the 

 southwest.
