Greenhouse Seating. 



SIZE OF PIPE. 



We contemplate building a greenhouse 

 27x100, twelve feet to the ridge, with 

 walls five feet high. There will be a 

 bench three feet wide along each wall 

 and three inside benches five feet wide 

 with walks all around them. How many 

 3-inch hot water mains should we have 

 overhead and how many 2-inch returns 

 under the benches to keep the house at a 

 temperature of 60 degrees at 10 degrees 

 below zero ? The base of our Idyle boiler 

 is about five feet below the surface. 

 "Where should be the highest point of 

 the flow pipes? W. E. D. 



Your house can be heated by using a 

 single 31/^-inch flow pipe under the ridge 

 and seventeen 2-inch returns. If you 

 prefer to use two flow pipes, use 2^- 

 inch, as they have sufficient capacity to 

 provide for the radiation supplied by the 

 2-inch returns. The highest point in the 

 hot water system should be at the point 

 in the flow pipe where it divides to 

 furnish the returns, i. e., the most dis- 

 tant point from the boiler. Connect the 

 expansion tank to the main return near 

 the boiler and elevate it as much as 

 possible, fifteen to forty feet.

THE BEST TYPE OF BOILER. 



There are so many different styles of 

 heating boilers on the market, each pur- 

 ported to be perfect, or at least the 

 best, that usually the florist is puzzled 

 when it comes to making a selection. 



Many of us have our ideas as to what 

 a good boiler should consist of and oc- 

 casionally these ideas get into print, 

 and are productive of some good, either 

 helping those in need of a new heating 

 apparatus in determining which one of 

 the many styles meets his requirements 

 aild combines the greatest number of 

 advantages, or in offering suggestions 

 for the manufacturers' consideration. 

 Just now we are looking for hot water 

 and steam boilers that will unite the 

 gases properly, giving us the most heat 

 from the least coal, with little or no 

 waste. 



I believe this can be accomplished in 

 no other way than by producing perfect 

 and rapid combustion of the fuel used. 

 Bricked-up steel tubular boilers are ad- 

 vocated in preference to the fire-box, 

 because the brick fire-box can be main- 

 tained at a higher temperature than

 the steel fire-box type, where the water- 

 jacket around the fire has a marked 

 cooling tendency. 



To combine the advantages of both 

 types in one, I advocate lining the fire- 

 box with at least four inches of fire 

 brick, top, sides, front and back, mak- 

 ing the box large enough to permit a 

 full size grate and heating surface. 

 Then brick in the boiler so that the 

 heat after passing through the flues 

 drops down at the farther end, return- 

 ing underneath the boiler toward the 

 front nearly as far as the fire-box, then 

 up over the top of the boiler, back to 

 the farther end and stack. 



One more suggestion, and one that I 

 believe is of vital importance, if proper 

 combustion is to take place. Have the 

 brick above the boiler arched the flat 

 way, two inches thick, and above this a 

 closed warming pan, covered with mag- 

 nesia, full width and length of the 

 boiler, at least six inches high, with an 

 opening near the rear end two-thirds 

 the area of the opening in the stack

 two 3-ineh openings, one at either side, 

 at least three inches in diameter for 

 fifteen horse-power boilers. Connect 

 with these openings three-inch pipes ex- 

 tending downward inside the fire-box

 pipes approach the bed of coals, put in 

 two tees, one for each 3-inch pipe, the
