The Weekly Florists' Review. 



Februabt 29, 1912. 



there should be two 3%-inch flow pipes. 

 One of these should supply house No. 1 

 and the other will answer for the other 

 two houses. Although a smaller ex- 

 pauBion tank would answer, it will be 

 well to select one with a capacity of 

 twenty gallons. Run the flow pipes 

 downhill and from the highest part of 

 each take a 1-inch pipe. Unite these 

 and connect with the expansion tank 

 with a 1%,-inch pipe. If convenient to 

 do so, elevate the expansion tank ten or 

 fifteen feet. However, five feet of ele- 

 vation will answer, and even less might 

 be used if necessary. 



For the heating of house No. 1 to 50 

 degrees, use three 2i^-inch flow pipes 

 and twelve 2-inch returns. Eun one flow 

 under the ridge and the others under 

 the purlins or upon the plates. Four 

 of the returns may be upon each wall 

 and the others under the Denches, or in 

 the walks if beds are used. 



For heating house No. 2, several ways 

 might be used. One of the simplest 

 would be to run a 3-inch flow pipe 

 through the house to the west end and 

 bring back eight 2-inch returns. This 

 would give a temperature of 50 degrees 

 in both ends of the house. To give a 

 higher temperature in the east end of 

 the house, take off a 2-inch pipe from 

 the overhead flow, which should drop 

 down and supply four 2-inch returns 

 running through the east end of the 

 house. In case, however, it is likely that 

 at any time only one end of the house 

 may require heat, it will be better either 

 to run a separate 2i^-inch flow pipe for 

 each room, or to run the 3-inch flow as 

 suggested above, but, instead of having 

 the returns run back through the east 

 room, connect them to the boiler by 

 means of one 2%-inch or two 2-inch re- 

 turns after uniting them at the partition 

 by means of headers. For heating the 

 east room, take off a 2%-inch flow from 

 the overhead 3-inch pipe, and supply 

 with this twelve 2-inch returns. 



For the carnation propagating house, 

 16x50 feet, which should have a tem- 

 perature of 50 degrees with about 10 

 degrees of bottom heat, run two 2ir^-inch 

 flows and ten 2-inch returns. Ihe re- 

 turns should be under the benches, which 

 should be partly enclosed to hold the 

 heat. 



... IN WESTERN OHIO. 



I have been much interested in the 

 information that I have found from 

 time to time in The Review, with ref- 

 erence to the piping and heating of 

 greenhouses, but none of the instruc- 

 tions have exactly suited my case. 

 Please tell me how, to pipe my two 

 houses, both to be used for a general 

 collection of plants, but one to be some- 

 what cooler than the other. The houses, 

 are each 15x50 and nine feet high to 

 the ridge. I have a ten horse-power 

 boiler. H. W. R. 



The foregoing description does not 

 give a clear idea of the construction 

 of the houses, but if the walls are 

 tight, without glass, and not more than 

 five feet high, and if the roofs are also 

 in good condition, it will be possible 

 to pipe one house, 15x50, so that a tem- 

 perature of 50 degrees can be main- 

 tained, by using one 2%-inch flow pipe 

 about eighteen inches under the ridge, 

 and six 2-inch T&t^^ixn pipes. Three of 

 these could be- on each wall; or, if 

 there is a bench in the middle of the 

 house, two of the pipes could be car- 

 ried underneath and the other pipes
