about the right amount of radiation to 

 ^iye (jO degrees in zero weather, but it 

 will probably be uecessary to use a 

 214-inch flow pipe aud a return pipe of 

 the same size, or connect each coil with 

 the boiler, using 2-inch pipes. 



PIPING FOR A LEAN-TO. 



I am enclosing a diagram which 

 shows a range of four houses, each 

 28 X 200, running east and west, and 

 protected at each end by a lean-to 

 wliich extends north and south. My 

 two Kroeschell boilers are located at 

 the east side of the east lean-to and 

 altout an equal distance from the north 

 and south ends of the range. Will you 

 kindly inform me how to pipe the 

 west lean-to? I wish to maintain a 

 temperature of 52 to 54 degrees. In 

 tiiis part of New York state the outside 

 temperature sometimes drops as low as 

 ]0 to 15 degrees below zero. 



The^iain or flow and return to the 

 entrance of the south house are both 

 <i-inch. Crosswise, east of the south 

 house, the flow and return are reduced 

 to 4-inch and 3-inch. Would it be ad- 

 visable to place a 4-inch tee just where 

 the 4-inch flow is reduced to 3-inch and 

 run a 4-inch flow along the south wall 

 in the south house, to enter the west 

 lean-to and there to branch off into 

 fourteen or sixteen 2-inch pipes, which 

 would enter a 4-inch return at the north 

 end of the lean-to .' The 4-inch return 

 Avould run east along the north wall 

 of the north house and from there to 

 the boilers, seven feet below the ground 

 level. All the houses slope about two 

 and one-half feet from west to east. 

 A. J. P. 



The plan shows a lean-to 150 feet 

 long, fourteen feet nine inches high to 

 the ridge and six feet to the eaves, at 

 the west end of the four houses, but 

 it does not show the width of this 

 lean-to. However, the lean-to at the 

 <3ast end of the houses is sixteen feet 

 wide and the west lean-to appears to be 

 the same. Unless there is glass in the 

 west wall of the lean-to, there should 

 be no difliculty in maintaining 55 de- 

 grees if ten 2-inch pipes are used. This 

 will afford about 900 square feet of 

 radiation. 



The 4-inch main, with which it is 

 proposed to connect the 4-inch main 

 for the lean-to, is now supplying about 

 700 square feet of radiation, and if the 

 900 feet in the lean-to and the 250 feet 

 in each of the flow and return pipes 

 are added, it will make some 2,100 feet 

 to be taken off from the 4-inch main. 

 The amount would be from 400 to 600 

 feet more if fourteen or sixteen 2-inch 

 pipes are used in the lean-to, instead 

 of ten, as recommended. At the best, 

 the 4-inch flow and returns leading to 

 the lean-to will have all they can do, 

 but, if possible, the flow should connect 

 either with the 6-inch flow or with the 

 boiler. If this can be done, there 

 should be no difficulty in heating the 

 lean-to with ten 2-inch pipes as heating 

 coils. 



Pontiac, 111.— W. J. Miller & Son se 

 cured, in time for the Christmas rush, a 

 new Ford motor delivery car and they 

 say, after giving the machine a trial, 

 that they feel sure they have solved 

 the quick-delivery problem. Christmas 

 trade, they state, was fully equal to 

 that of last year, with this difference, 

 that the principal demand this season 

 was for cut flowers rather than for 

 potted plants. 



More Heating Surface 



and less water space than 

 is contained in any other 

 boiler. (Note the many 

 flues set close together.) 

 This is one reason why 

 the users of the 



''Superior Standard" Greenhouse Boflers 



find them perfectly satisfactory. We frequently receive re-orders 

 from florists who have tested these boilers thoroughly and found 

 them even " Superior" to our claims.
