Cast Iron Boilers Require Twice tke Amonnt of Coal ; Kroeschell Boiler Only On^llalf 



I bousrht a No. 3 Boiler In 1901. We had a corrugated cast Iron fire-box boiler and sectional cast Iron boiler 

 before we bought yours in 1901. The cost ot beating with this boiler is one-half less than It was with my 

 cast Iron boilers. Your No. 8 Boiler, which we bought recently of you, is not being run to its capacity.

posed to inake the connection. If 

 steam is to be used, almost any method 

 of connecting the pipes would probably 

 answer, but if the pipes are for hot 

 water, care must be taken not to ob- 

 struct the flow. The best way would 

 be to extend the present coils, but if 

 that is done it might be necessary to 

 put in larger flow and return pipes. 

 Not more than 200 square feet of 

 radiation should be carried in 2-inch 

 flow and return pipes. 



If this can not be done, run inde- 

 pendent flow and return pipes to the 

 new coils, unless a direct circulation 

 can be made with the old coils by 

 means of nipples not less than two 

 inches in diameter. 



TWO ILUNOIS HOUSES. 



We are building two east and west 

 greenhouses, 25x90 feet, connected, but 

 with a partition between the houses. 

 We shall use hot water heat. We have 

 not decided on the boiler as yet, but 

 are figuring on a mercury system. The 

 south house will have four feet of glass 

 in the south wall. Both ends of the 

 south house will be glass and the east 

 end of the north house will be glass. 

 The north wall will be double boarded, 

 with building paper between. The 

 houses are protected on the north and 

 west by a hill. There will be four 

 4%-foot benches in each house, those 

 in the south house being solid, in the 

 north house raised. Using 3-inch pipe 

 for flows and 1^-inch for returns, how 

 many pipes will be needed and how 

 would you run themt We wish to 

 maintain a temperature of 65 to 70 de- 

 grees. During the months of Novem- 

 ber, December and January we intend 

 to grow a crop that requires a cool 

 temperature, about 45 degrees, and the 

 system will have to be arranged so 

 part of the heat in each house can be 

 cut out during that period. How deep 

 will our boiler pit have to bet What 

 size of flue and how high a stack will 

 be needed t G. & F. 



To heat houses 25x90 feet to 65 de- 

 grees will require two 3-inch flow pipes 

 and twenty-three IMs-inch returns. It 

 would be better, however, to use three 

 2 ^^ -inch flow pipes and eighteen 2-inch
