The Weekly Florists' Review^ 



January 11, 1912. 



$40, and that copper flues, No. 11 gauge, 

 would cost $102. Since No. 11 is the 

 standard gauge for high pressure steam 

 copper flues, would aot No. 14 be ade- 

 quate for hot water, with no pressure 

 except from the expansion tank, eight 

 feet above the boiler? This would 

 reduce the cost to $70. 



Since copper will not scale and is- 

 therefore of great durability, and since 

 by its use one is enabled to get the 

 heat applied much closer to the water, 

 would it not seem advisable, from an 

 economical point of view, both in dur- 

 ability and daily service, to use copper 

 flues? What reader of The Keview can 

 tell us from experience?

BOILEB UNDEB BESIDENCE. 



I have two connected houses, 20 x 190 

 and 30 x 190. They measure twelve 

 feet to the ridge pole and four and 

 one-half feet to the eaves and have 

 board sides. I have two boilers, twenty 

 and twenty-four horse-power, and use 

 hot water. Will these boilers heat an- 

 other house, a new one, 30 x 180, along- 

 side the old houses? The flow pipes at 

 present start over the boilers, about 

 eighteen inches from the top of the 

 boilers, and the return pipes come in 

 about one foot lower. I want to know 

 the proper way to pipe the houses. At 

 present the flow pipes and return pipes 

 are all in the walks and the flow pipes 

 are only about six to ten inches above 

 the return pipes. The expansion tank 

 is connected to the return pipes. 



As I understand it, the flow pipes 

 should rise six to ten feet over the 

 boilers, run with a gradual fall to the 

 opposite end of the houses and then 

 drop to the return pipes, which should 

 also have a good fall back to the boil- 

 ers. In my case it is difficult to let the 

 flow pipes rise directly over the boilers, 

 as the boiler room is under my dwell- 

 ing. Could I let the flow pipes rise, 

 say, four feet above the boilers, then 

 go out from under the building and rise 

 a second time, to within three or four 

 feet of the ridge poles? I am located 

 in southern Kansas. J. L. V. 



While it is well to have the flow pipes 

 rise to the highest point in the system 

 as soon as possible, it will make but lit- 

 tle difference if the plan suggested is 

 followed and the highest point is not 

 reached until after the flow pipes have 

 entered the greenhouses. In fact, al- 

 though the downhill system should be 

 used whenever possible, if the condi- 

 tions are such that it will be easier to 

 install an uphill flow pipe it will give 

 good results when the returns are 

 higher than the top of the boiler. 



The inquiry does not give the temper- 

 atures desired in the houses, but if an 

 average of 60 degrees would be the 

 maximum temperature, which would 

 probably be ample, there should be no 

 difficulty in heating the three houses, 

 provided the boilers are up to capacity 

 and everything is properly arranged. 

 There is, however, only a little surplus 

 capacity and it would require skillful 

 handling to maintain a temperature of 

 60 degrees in all of the houses when 

 the outside temperature drops below 

 zero. For 60 degrees use in the new 

 house, 30 X 186, either three 3-inch or 

 five 2 ^^ -inch flow pipes and fifteen 2- 

 inch returns. For 50 degrees use only 

 ten returns.

More Heating Surface 



and less water space than 

 is contained in any other 

 boiler. (Note the many 

 flues set close together.) 

 This is one reason why 

 the users of the 



''Superior Standard" Greenhouse Boilers 



find them perfectly satisfactory. We frequently receive re-orders 

 from florists who have tested these boilers thoroughly and found 

 them even " Superior" to our claims.
