cooling of the water until it has passed 

 the highest point in the system. This 

 arrangement also makes it possible to 

 dispense with the use of air valves, as 

 the expansion tank should be connected 

 with the highest point in the system. 



PIPINO A UBAN-TO. 



I have a lean-to greenhouse, 10x20 

 feet, that I want to use for tomato and 

 cabbage plants, starting February 15. 

 I have a Wilks hot water boiler and 

 should like to know whether I can use 

 1^-inch pipe for the flow and 1-inch 

 pipe for the returns. Those are the 

 only pipe sizes for which the boiler is 

 tapped. The lean-to runs east and west, 

 having a building on the north side and 

 three feet of glass in the other three 

 sides. If I can use the 1-inch pipe for 

 returns, how many should go on each 

 side? F. D. W.— O.

A Wilks hot water boiler with a grate 

 14x30 inches is sufficiently large to heat 

 a greenhouse several times as large as 

 the one described, especially if it is not 

 to be used until after the middle of 

 February. 



The method of arranging the heating 

 pipes will be determined to some extent 

 by the location of the doors in the house. 

 While 1-inch pipe may be used for the 

 coils in a house as small as the one de- 

 scribed, provided the lowest part of the 

 coils is above the top of the heater, 1%- 

 inch pipe would be preferable for the 

 flows and returns. This can be used 

 for the boiler described by connecting 

 the flows and returns by means of re- 

 ducing couplings or ells. Eun the flow 

 pipe along the rear wall of the lean-to 

 and run part of the returns back along 

 the rear wall. The others could be car- 

 ried along the end of the house and the 

 outside wall to the heater. About 300 

 linear feet of 1-inch pipe will be re- 

 quired for the returns. This can be used 

 in a coil of six pipes on the back wall, 

 with the same number of pipes in the 

 coil running along the end and the outer 

 wall of the house. In case the coils do 

 not run across the end, there should be 

 fifteen lines of 1-inch pipe in the coils. 

 By connecting a mercury generator to 

 the system it will be possible to reduce 

 the number of the returns about one- 

 third.
