Greenhouse Heating. 



FROM STEAM TO HOT WATER. 



Can a steam heating system be 

 changed into a hot water system, and 

 howl Our boiler is a twenty-five horse- 

 power horizontal, for steam. It has two 

 outlets on top for 4-inch pipe; the re- 

 • turn openings are also for 4-inch pipes. 

 The boiler is two feet lower than the 

 lowest return pipe. How high must the 

 flow pipe rise to insure circulation f 

 There are two greenhouses, each 25x125, 

 and the location is southern Pennsyl- 

 vania. H, E. 



To use the boiler described, for hot 

 water, no change will be necessary ex- 

 cept that there will be no occasion for 

 retaining the water column, steam 

 gauge and safety valve. 



Nothing is said regarding the con- 

 struction of the houses or the tempera- 

 ture desired. If there is no glass in 

 the walls it will be possible to main- 

 tain a temperature of 50 degrees by 

 running a 4-inch flow pipe from the 

 "boiler to the farther end of each house 

 and connecting each flow pipe with ten 

 2-inch returns, to be placed on the 

 walls or under the benches. The flow 

 pipes should be carried through each of 

 the houses at a slight fall, from three 

 to four feet below the ridges. Connect 

 the highest point in each flow pipe with 

 the expansion tank, which should be 

 several feet higher, if it can be ar- 

 ranged. If a temperature higher than 

 50 degrees is desired, close the system 

 Dy attaching a generator to the expan- 

 sion pipe. 



IN SOUTHERN NEW HAMPSHIRE. 



Will you kindly advise me regard- 

 ing the piping of my greenhouse for 

 hot water, stating the number of feet 

 of radiation for a temperature of 50 

 degrees when the thermometer shows 

 10 degrees below zero outdoors? The 

 house is 18x30, even-span and nine feet 

 high to the ridge, with walls of con- 

 crete three feet high. T. C. K. 



To heat- a house 18x30 feet to 50 

 degrees^ when the outside temperature 

 is 10 dtfglTOs below zero, run a 2%-inch 

 flow pipe at a slight fall one foot below 

 the ridge to the farther end of the 

 house, where it should be dropped down 

 and connected with eight 2-inch re- 

 turns. Four of these should be carried 

 in each direction across the end of tjie 

 house, and along the side walls bacTc 

 to the boiler. After the flow pipe en- 

 ters the house, this arrangement will
