Tlic Weekly Florists' Review^ 



f. ■ . ^ . 



June 29, 1911. 



^size of boiler, of sectional type, will be 

 needed to heat^lie house in good shape? 

 Is it absolutely' necessary to carry the 

 flows on the purlins, to get the best re- 

 sults? Is wrought iron pipe the best to 

 use? H. D. W. & S. 



Under the rather severe conditions 

 mentioned, to heat a house 25x50 feet to 

 60 degrees, it will be well to put in 

 three 2i^-inch flow pipes and sixteen 

 2-inch returns. With this arrangement 

 it will be advisable to have one of the 

 flows under the ridge, although it could 

 be carried under the benches if the re- 

 turns are well above the boiler. The 

 boiler should have a rating of 800 to 

 900 square feet of radiating surface. 



Whether wrought iron or east iron 

 pipe is preferable is largely a matter of 

 opinion. Some think wrought iron is 

 better, for one reason because it comes 

 in longer lengths and has threaded 

 joints; but others prefer cast iron and 

 one of the largest greenhouse building 

 concerns recommends its use with the 

 statement that rust or caulked joints are 

 the easiest joints there are to make. 



BUILDING A BRICK STACK. 



I am thinking of building a brick 

 smokestack in place of my iron stack, 

 which lasted only two winters. The 

 present stack is eighteen inches in diam- 

 eter and twenty feet high, which gives 

 ample draft. The brick stack will be 

 about seven feet from the boiler. Would 

 an 8-inch wall and a height of eighteen 

 feet be sufficient? How much larger 

 should the stack be at the base than at 

 the top? E. P. M. 



There is nothing quite definite in the 

 question regarding what will be re- 

 quired, and all that can be done is to 

 base the answer upon the capacity of 

 the present stack. Especially as the 

 chimney is to be seven feet away from 

 the boiler, it will probably be well to 

 make it five feet higher rather than 

 lower. If it is built about 16x20 inches 

 inside, and with the walls eight inches 

 thick and twenty-five feet high, it Will 

 probably answer. In case other houses 

 are to be added, it may be advisable to 

 make the chimney sufficiently large to 

 provide for them. However, it will be 

 possible to increase the capacity of the 

 chimney fully fifty per cent by adding 

 ten or twelve feel to its height when-, 

 ever the other houses are built, if the 

 chimney is so constructed as to permit 

 this. The flue is so short that it would 

 not be worth while to make any change 

 in its interior diameter, but, unless the 

 chimney is to be supported in some way, 

 the, foundations should be made broad 

 and firm and the wall should be built 

 heavier up to the height of ten or' 

 twelve feet. 



IN CENTRAL MICHIGAN. 



We are told that black iron pipes 

 radiate heat better than galvanized 

 pipes and that painted pipes are the 

 worst. We are also told that 1-inch 

 piping is better than 1%-inch. Please 

 give us your opinion on this. 



The floor of our present house is two 

 feet below the level of the ground, with 

 the piping under the benches. We are 

 planning to build an extension on top 

 of the ground, using beds instead of 

 benches. The flow would work all right 

 in the addition, but how should we plan 

 the return heating pipes? The present 

 house is 15 x 20. The addition would 

 be twenty feet wide and probably
