lar kiDd of boiler, but will probnl)ly use 

 some kind of round or sectional boiler. 

 IIcw n'ueh below the greenhouse floor 

 fchoulil the boiler be located, auv! wliero 

 should the expansion tank be located? 

 Vve expect to put our boiler in a build- 

 ing located about six feet from the 

 greenhouse, and could put the expansion 

 tank in this building or in the green- 

 house, whichever 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. K. P. 



My preference for general purpose 

 houses is to run them north and south, 

 wilh the head or boiler house at the north 

 end. Even-span houses get a little more 

 sunshine when set r.orth and soutii than 

 in any other position. 



For a house thj 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 autoniati- 

 cally. You can use ll^-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-inch flow. In 

 a hot water plant all A-alves 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.
