The Florists' Review 



OCTOBKB 14, 1915. 



The inquiry does not state what tem- 

 perature is desired in the old house, but 

 x£ 60 degrees will suffice, with 50 to 55 

 degrees in the new house, I would sug- 

 gest the use of two 2% -inch flow pipes 

 the entire length of the building, with 

 eight 2-inch returns, placing one flow 

 and four returns on each side. 



The circulation would be improved by 

 placing the flow pipes on the wall 

 plates, or, better yet, about two feet 

 below the ridge, as it would then be 

 possible to start with the coils at the 

 middle of the east end of the house, 

 and this might be necessary in order 

 to keep out the frost on cold nights 

 when there is a high wind from the 

 east. 



BOILEB WILL BE TOO SMALL. 



I have just added a house alongside 

 the one I already had, as shown in the 

 enclosed sketch, and I wish to know 

 how much pipe will be needed to heat 

 the new house to a temperature of 55 

 ■degrees in zero weather. The piping in 

 the old house consists of one 3-inch 

 flow and four returns in the center, and 

 one 2%-inch flow under the purlin on 

 each side, to feed the side coils, each 

 of which is composed of five 1^-inch 

 returns. 



I have extended the boiler room 

 across the end of the new house. Can 

 I continue the main from the boiler to 

 the center of the new house, to be con- 

 nected with the new piping? Would 

 you pipe the new house according to the 

 same plan as is used in the old one, 

 and how much new piping will be need- 

 ed? Will the five returns under the 

 gutter be enough to keep the snow 

 melted? Can I heat the two houses 

 with my present boiler, which is rated' 

 for 750 square feet? It is a round, up- 

 right boiler, with a 17-inch grate. How 

 much glass surface have I and how 

 much radiation will be needed? State 

 the size of mains and returns. If the 

 boiler is not large enough, can I success- 

 fully couple it with another boiler? 

 Can I use a mercury system with an 

 open hot water system? 



J. O. S.— N. Y. 



The sketch shows the old house to be 

 20x30, with one exposed wall, boarded 

 to the eaves. The new house adjoins 

 the old one on the east and has double 

 flashes on the east side. This house is 

 27x30. As nearly as can be estimated 

 from the data furnished, the old house 

 has 860 square feet of glass, besides 

 240 square feet of wooden wall, equiva- 

 lent to about fifty square feet of glass. 

 The new house has 1,270 square feet of 

 glass and eighty - one square feet of 

 wooden wall. The piping in the old 

 house is not far from 275 square feet, 

 which should furnish a temperature of 

 -55 to 60 degrees in zero weather. 



In the other house I would suggest 

 the use of three 2i^-inch flow pipes 

 and thirteen 2-inch returns. One of 

 the flows should be placed under each 

 purlin and the other four feet below 

 the ridge. Five of the returns should 

 be on the outer wall, and four in coils 

 on the inner wall and under the middle 

 bench. With five 1%-inch pipes in one 

 house and four 2-inch pipes in the 

 other, on the center wall, there should 

 be no trouble from ice. If preferred, 

 seven l^^-inch pipes maj' be used on 

 the outer wall and six in each of the 

 other coils, in place of the thirteen 2- 

 inch pipes already specified. The 3-inch 

 main from the boiler may be continued

WHAT would happen- if your night 

 man fell'asleep some night in zero 

 weather? What if you should oversleep, 

 or a cold wave hit your greenhouse when 

 your heat is at the minimum? It woulid 

 mean ruin to your plants— possibly ruin 

 to you. There have been many such 

 cases. 



But not if you are equipped with the 

 STANDARD THKRM08TAT. The 

 Standard lHannostat protects, you 

 from just such dangers. It will ring a 

 bell at your bedside when danger is near.

 pensable to the up-to-date grower. Yqu 

 know preparedness countsi Get the
