The Florists^ Review 



Sbi'tembeu 20, 1917. 



give us some suggestions about the 

 (lijiiiiiiig of the system. R. B. — Okla. 



The sketch shows four houses, 21x18(5, 

 ill the west block, with two 2-inch flows 

 and six 114-inch returns. In the east 

 block there are three houses, 21x100, 

 heated by three 2-inch flows and six 

 1^4 -inch returns in each house. The 

 north block consists of three houses, 

 21x75, heated by two 2-inch flows and 

 one 11/4 -inch flow and by five li/4-ineh 

 rotunis. The south block contains two 

 houses 300 feet long and respectively 

 twenty-eight feet eight inches and 

 twenty-seven feet four inches wide, and 

 heated by three 2-inch flows and six 

 114 -inch returns. 



Although it may be a little high to 

 rate the boilers at sixty horsepower, 

 they are certainly of fifty-six liorse- 

 power and the two of them should be 

 able to handle tlie radiation for 00,000 

 square feet of glass, the amount in the 

 houses, as stated in the sketch. For 

 the jmrposes mentioned, 7,;)00 scpiare 

 feet of radiation would be sunicicnt in 

 the northern states, where the tempera- 

 ture drops to 10 to 20 degrees below 

 zero, and more tlian is required in Okla- 

 homa. 



So far as we can judge from the 

 description of the piping, there is no 

 reason why satisfactory results cannot 

 be obtained, provided sufficient pressure 

 is carried to enable the trap to work. 

 Although a smaller return pipe would 

 answer, we do not think it would help 

 much to make the change proposed and 

 we would advise the carrying of a higher 

 ])ressure in the boiler. 



To correct the difficulty mentioned, 

 we would place valves on both ends of 

 three of the return pipes in each house, 

 and would take out all but one flow pipe 

 in each liouse. except in the south 

 houses, where two will be needed. 



It is stated that the boiler is three 

 feet below most of the returns. If this 

 moans that the top of the boiler is three 

 or even two feet below the returns, a 

 by-pass around the trap might be put 

 in, so that a gravity system could be 

 used in mild weather. 



RUN A FLOW NEAR THE RIDGE. 



Please advi.se mo regarding the heat- 

 ing of a j^rooiihouso l.S'l'XlOO. The side 

 walls are four and one-half feet high 

 and are of wooden construction, with no 

 glass. The ridge is nine feet from tlie 

 floor. There will be three 3-foot benches, 

 with heat under the outside benches 

 only. The liouse will be heated by 

 stoam from a large central ]>lant. T am 

 jilaiining to use four rows of IVj-incli 

 ]iil)e on the side walls, placing the top 

 rdw twelve inches below the ])ottom of 

 the bencli. The service house, from 

 wliich steam will enter the greenhouse, 

 is at the north end. 



P. A. H.— Utah. 



We do not feel sufficiently -well in- 

 fdrmed about the winter temperature in 

 I'tah to advise definitely regarding the 

 piping, but we would suggest running a 

 :.' inch flow ])i])c about two feet below 

 the ridge, with which to sn])]ily the 

 coils on the side walls. Where tlie tem- 

 ))erature at night occasionally drops to 

 10 degrees below zero we would use 

 threo 114 -inch coils on each wall, but if 

 1(1 degrees above zero is a minimum 

 temjierature, only two returns u])on each 

 wall will be required, even with a steam 

 ]iressiire of not more than five ]>ounds. 



A Uniform 

 Temperature 



means better flow- 

 ers—more' naturally 

 ■Town. The More- 

 head System main- 

 tains an even, con- 

 sistent temperature 

 throughout your grow- 

 ing houses by elimi- 

 nating sluggish circu- 

 lation and delivering 

 every drop of the 

 condensation, which 

 is now allowed to clog 

 up your steam lines, 

 directly back to the 

 boiler wbile it is hot. 



You not only get 

 better flowers, but you 

 also save a large per 

 cent of your fuel.
