Kroeschell Versus Cast Iron 



The No. ft boiler Is heating 6000 square feet of {rlaes; I believe It vould take rare of 18,000 

 square feet. Have no trouble to keep temi eratuiee of 66° to 60°; 1 could ketji SO" to H»° If I bad 

 to. BurlPK the coldefet nlfthte I filed at 9:00, 12:00 and 3:00 o'clock. Tbe bdler Las grlven 

 entire Batlt-lactlon, in fact, more than I exptcted. Pretlou^ to this I had a cast In n boiler, but 

 would not have It for a gilt now. If I know of any one needlBR a gocd boiler, I shall recom- 

 mend the Kroeschell Boiler above all. John Lietzau, Geneva, III. 



Have no trouble to keep up temperatures in my bouses with tbe No. 10 Eroefchell Boiler. 

 The boiler has grlvtn entire katlsfactlcn. Me bad a cast iron sectional boilei — I wouldn't have 

 one for a gift any more. -■- — John Otto, Neenah. Wis.

ONE HOUSE AND A LEAN-TO. 



Kindly inform me what size of boiler 

 and how many square feet of radiation 

 -yor direct radiation, if there is any 

 difference — should be required to heat 

 2,500 square feet of glass. There are 

 two houses. One of them is 16%x80 

 and nine feet to the ridge, with no glass 

 in the exposed side, but with one glass 

 gable. This house is used for carna- 

 tions and needs a temperature of 50 to 

 55 degrees. It contains one 3-inch 

 flow and ten 2-inch retilrns. The other 

 house is a lean-to, built against the 

 house just described, and against the 

 dwelling house on the north side. The 

 houses run east and west. The lean-to 

 is 14x60 and has two glass gables. It 

 contains one 3-inch flow and ten 2-inch 

 returns and should have a temperature 

 of 60 degrees. The outside temperature 

 here, in southeastern Pennsylvania, sel- 

 dom drops lower than 10 degrees above 

 zero. 



The present boiler is too small. The 

 boiler shed is at the west end of the 

 80-foot house. Is one 3-inch flow suf- 

 ficient to feed ten 2-inch returns? Al- 

 together, including the 3-inch flows, 

 there is the equivalent of 1,700 lineal 

 feet of 2-inch pipe in the houses. The 

 boiler must have the capacity to heat 

 1,900 feet of 2-inch pipe, in order to 

 provide for a surplus. A gravity sys- 

 tem, with an open tank, is used. Is the 

 present quantity of piping suflScient to 

 maintain the required temperature? 



H. S. 



For the carnation house, 16l^x80, not 

 more than 400 square feet of radiation 

 is needed to maintain a temperature of 

 55 degrees in zero weather, and this 

 would be furnished by one 3-inch flow 

 and seven 2-inch returns — or, better 

 yet, by two 214-inch flows and six 

 2-inch returns. In the lean-to only one 

 flow and six returns would be needed. 

 Beally the tw^o houses require not to 

 exceed 700 square feet of radiation, and 

 any good boiler that is rated for 900 

 square feet should be of ample size. 



The term "direct radiation" is ap- 

 plied to systems where the heating sur- 

 face is heated directly by the circula- 

 tion of hot water or steam, as is com- 

 monly the case in greenhouses. 



A 3-inch flow pipe is amply large 

 enough to heat ten 2-inch returns not 

 over 100 feet in length, provided they 

 are above the top of the heater. If 

 there is difficulty in maintaining the 

 desired temperature, something must
