lar kind of boiler, but will probably use 

 some kind of round or sectional boiler. 

 Hew n^uch below the greenhouse floor 

 bhould the boiler be located, an^l wliere 

 should the expansion tank be located? 

 Vve exiject to put our boiler in n build- 

 ing located about six feet from the 

 greenhouse, and could put the expansion 

 tank in this building or in the green- 

 house, M'hichever way is preferable. 

 Must the tank be located so as not to be 

 exposed to a freezing temperature? 

 Here, in northwestern Pennsylvania, the 

 temperature is sometimes 20 degrees be- 

 low zero, but only once in a while. We 

 have zero weather, however, quite fre- 

 quently. A. E. P. 



My preference for general purpose 

 houses is to run them north and south, 

 with the head or boiler house at the north 

 end. Even-span houses get a little more 

 sunshine when set Korth and south than 

 in any other position. 



For a house th'3 size you mention, I 

 should say, use hot water by all means, 

 unless you have gas fuel, so as to regu- 

 late the fire in a steam plant automati- 

 cally. You can use l^^-inch or 2-inch 

 pipe for this house; if you use 2-inch 

 pipe it will require nine lines, eight 

 under the benches and one overhead 

 flow, unless you prefer to place all be- 

 neath the benches. If li^-inch pipe is 

 used it will require twelve pipes under 

 the benches, fed by one 2-iiich flow. In 

 a hot water plant all valves should be 

 gate valves. To reduce radiation, place 

 a valve in each end of the pipes under 

 the benches which you wish to put out of 

 commission. This is seldom necessary 

 with hot water, however, as the tempera- 

 ture during mild days can be controlled 

 by firing and by use of the throttle 

 valve on the main flow. 



I would place the boiler eighteen 

 inches to three or four feet below the 

 level of the greenhouses. Nothing is 

 lost by a deep pit. Place the expan- 

 sion tank in the boiler house or on top 

 of it, and give protection. I do not like 

 the idea of a detached boiler house. 

 You will find your workroom unhandy.
