HOT WATER HEATING. 



^--i fljHr. reply to question 542, in the March number of Canadian 

 Horticulturist, coming as it does from such excellent 

 authority, will relieve many persons of doubts which still 

 exists respecting the merits of hot water heating as applied 

 to dwelling houses and other buildings, as well as to green- 

 houses. Mr. Beadle's words, " I unhesitatingly give the 

 preference to hot water," will carry conviction to all who 

 know anything of that gentleman's experience in such matters. 



The subject of heating buildings by hot water, however, is in its infancy, 

 and will not take its proper place in household economy until it is more gener- 

 ally understood and its practice greatly simplified. 



I do not propose to write an essay on this subject at present, but have 

 thought that a few pointers to intending builders, from one who nas had nearly 

 twenty-five years experience with this most economical method of heating 

 dwelling houses, might be of service at present. 



1. The boiler must be of sufficient capacity to heat the water sufficiently 

 without forcing, during the coldest nights. 



2. The piping must be of sufficient capacity to hold an abundance of 

 water for the coldest weather. 



3. The estimate for the length of the piping must be made on the quantity 

 oj water required, and due provision must be made to distribute the same to the 

 necessary points with the least length of pipe, i.e., pipe of the largest workable 



4. Pipes must be laid with sufficient fall only, to prevent " pockets " being 

 formed. One inch in one hundred feet is sufficient for this purpose if of the 

 proper size and of the best quality, provided they are put in place by a competent 

 workman. 



5. No coils, or substitutes for such, should be permitted above the floors. 

 Such furniture is utterly useless and very expensive. 



6. The circulation of the water depends upon the difference between the 

 weight of the ascending and the descending columns. 



7. The difference in weight in the two columns is produced by the 

 difference in the temperature of the air surrounding the pipes and the tempera- 

 ture of the water in the pipes. When the temperature is the same there will be 

 no circulation. 



8. The same amount of heat will be given off from the same area whether 

 the pipes are laid horizontally or perpendicularly. 



9. The cheapest work is that done by the most competent workmen. 

 Other " pointers " may be given, as well as further explanation made of the 



foregoing, should circumstances require them.
