Greenhouse Heating. 



Subscribers are invited to write the 

 Editor of this Department with regard to 

 any details of greenhouse heating that 

 are not understood. But please do not 

 ask The Beview to make a choice of ap- 

 paratus for you. The greenhouse heating 

 equipment advertised in this paper is, wq 

 believe, the best for the trade to buy, 

 and each article the best in the special 

 field of its adaptation. 



BOILEB TUBES FOE PIPING. 



We should like to get your advice re- 

 garding used boiler flues as a medium 

 for hot water heating. It seems to me 

 that as flows they would serve the pur- 

 pose as well as standard pipes, as the 

 sun reaches the flows at all times. On 

 the other hand, if used as returns 

 under benches, where they would be 

 subject to continual moisture and would 

 be completely screened from sunshine, 

 they would soon rust out, I think, ow- 

 ing to their light construction and 

 questionable quality. We are aware 

 of the fact that the circulation is 

 much better and faster with their use, 

 and this is a point in their favor. What 

 would you estimate as the average life 

 of such pipes under benches?

From the fact that boiler tubes are 

 usually thinner than standard wrought 

 iron pipes, the latter would prove more 

 durable, but if all rust scales are care- 

 fully removed from the exterior of the 

 boiler tubes and they are then covered 

 with a paint composed of lampblack 

 and linseed oil, they will last a long 

 time. After the pipes are in place, a 

 second coat should be applied,^ with 

 special care in painting near the joints. 

 If care was taken to remove all of the 

 scale, it would not be necessary to re- 

 paint the pipes for two years, although 

 if rusty spots are noticed they should 

 be touched up occasionally. Just how 

 long boiler tubes can be relied on as 

 heating pipes will depend, of course, 

 upon the extent to which they have 

 been rusted. This really should deter- 

 mine whether or not they should be 

 used. 



I fail to understand why it is stated 

 that "the circulation is much better 

 and faster with their use," since the 

 circulation in a 3-inch boiler tube would 

 not be appreciably faster than in a 

 3-inch standard pipe. Since the exte- 

 rior diameter is used as the measure- 

 ment of boiler tubes, while the interior 

 diameter is used for standard pipes, 

 the latter would afford slightly more 

 radiating surface, but this would per- 

 haps be nearly counterbalanced by the 

 greater radiation through the thin- 

 walled boiler tubes.
