The Florists' Review

walls is covered with heavy roofing 

 paper and well protected underneath. I 

 want a temperature of not less than 

 50 degrees in zero weather, which is 

 considered pretty cold here, in southern 

 Pennsylvania, although last winter the 

 thermometer registered as low as 36 

 degrees below zero. I have tried to 

 give all the necessary information tgid 

 I think that you will be able, with the 

 help of the diagram, to understand my 

 wants. D. E. L. 



The sketch shows three houses, of 

 which No. 1 is 16x54, with three feet 

 of glass in one wall. It appears to 

 have only three 1%-inch pipes under 

 one of the side benches. For 50 de- 

 grees not less than seven pipes should 

 be used, of which four should be along 

 the south wall. House No. 2 is 20x56 

 and ten feet to the ridge, with two and 

 one-half feet of glass in one wall, while 

 the other side adjoins house No. 3. This 

 house has five pipes on the exposed side 

 and four on the other. The radiation 

 is not far from the proper amount. 

 House No. 3 is 21x85, with a 9%-foot 

 rid^e, and with two feet of glass in the 

 east wall and about one-third of the 

 west side. This house has five 114-iiicli 

 returns on one side, across both ends of 

 the house and for thirty feet on the 

 other side. The radiation would be im- 

 proved by extending the main along 

 both sides of the house. 



Except in house No. 2, the radiation is 

 not properly proportioned, but just what 

 the trouble is cannot be told without 

 going over the plant. It is possible 

 that the pipes need grading, or some- 

 thing may be wrong with the air 

 valves. If the coils drain by gravity, 

 they should be three or four feet above 

 the water level of the boiler. If steam 

 traps and pumps are used, they should 

 be looked after. 



If the houses are to be heated with 

 hot water, run a 3-inch flow pipe to 

 each of houses 1 and 2, and a 4-inch 

 flow to house No. 3. In house No. 1 

 use three 2i^-inch flow pipes and six 2- 

 inch returns. Houses No. 2 and 3 

 should have three 2%-inch flow pipes 

 and seven returns. So far as can be 

 determined from the drawing, there 

 should be no difficulty about carrying 

 the flow pipes to houses 1 and 2 so that 

 they can enter about two feet below 

 the ridge and then be broken up into 

 three 2% -inch flows. The flow to house 

 No. 3 may have to run under the floor 

 of the workroom, unless it can be taken 

 into the gable.
