economically with the boiler described, 

 the margin ia a rather small one. 



To heat the smaller houses, I would 

 suggest the use either of three 2% -inch 

 flows and six 2-inch returns, or two 2%- 

 inch flows' and eight 2-inch returns. For 

 the house 30x100 I would use three 2^/^- 

 inch flows and ten 2-inch returns. One 

 of the flow pipes should be upon each 

 wall plate, and when three are used the 

 third flow should be two or three feet 

 below the ridge. The returns should be 

 placed on the walls or under the benches. 

 Or, when solid beds are used, the returns 

 may be either in the walks or on the 

 purlin and ridge posts over the beds. 



PBES:^XT PIPING INADEQUATE. 



Some time ago I sent to you an in- 

 quiry in regard to the piping of my 

 houses, but I did not supply sufficient 

 details and so your reply did not cover 

 the ground just as I wished. The two 

 houses I referred to, each 12x21x110 

 feet, are enclosed as one; that is, there 

 is no partition between them. The side 

 walls are eight feet high, and the upper 

 half of them is glass. The temperature 

 desired is 65 to 70 degrees in this Penn- 

 sylvania climate. I heat with hot water. 

 In one of the houses there are eight 

 2-inch pipes for the flows and eight pipes 

 of the same diameter for the returns. 

 In the other house there are six flows 

 and six returns, all 2-inch. Will this 

 piping be sufficient to heat the two 

 houses? M. J. C. 



In heating the houses described, the 

 use of eight 2-inch returns and the same 

 number of flow pipes should maintain a 

 temperature of 65' degrees in zero 

 weather, but you would not be likely to 

 secure more than 55 degrees with six 

 fl^ows and six returns, unless a circulator 

 of some kind is used or heavy and waste- 

 ful firing is practiced. 



Instead of piping the houses in the 

 way mentioned, I would advise the use 

 of five 21/^-inch flow pipes and twelve 

 2-inch returns in each house. Place one 

 flow pipe upon each plate, another under 

 the ridge and the others under the 

 purlins. About three of the returns 

 should be on each wall and the others 

 distributed under the benches, or in the 

 walks in case solid beds are used.

Do you want true heating values for your money I Many ... 

 florists, to their sorrow, have made the mistake of buying 

 cast iron boilers, which, because of their ratings, appeared , 

 to be cheaper than the Kroeschell boiler. « 



The extravagant ratioKB of «;a8t iron boilers are mislea41nij> AQd have been 

 the cause of much disappointment and serious trouble to many i^i^wers. 

 The fuel waste is enormous when cast iron boilers are used for conunercial 

 purposes, such as greenhouse heating.
