For example, a boiler rated in these 

 catalognes to take care of 1,000 square 

 feet of glass in a greenhouse would be 

 exactly the same size whether used for 

 hot water or steam heat, and this ap- 

 plies to boilers for ranges of any size. 

 You will find this statement borne out if 

 you will consult practically any boiler 

 catalogue. 



It is shown in these catalogues that 

 the same boiler in their water and steam 

 ratings merely differs by rating it higher 

 in the amount of heating pipes for hot 

 water by about fifty per cent in order 

 to take care of the additional amount 

 of hot water surface necessary; that is, 

 a certain boiler having a rating of 1,000 

 feet of steam radiation will be rated at 

 about 1,500 feet of hot water radiation. 

 The net result would be, the houses will 

 be heated to the same temperature by 

 the same boiler, no more, no less, vntix. 

 the same expenditure of coal, the only 

 v/ difference being that with steam heat 

 there would be installed 1,000 square 

 feet radiation, while with hot water 

 there would be required 1,500 square feet 

 radiation in the houses. 



A properly designed boiler will heat 

 the same building to the same tempera- 

 ture using steam or hot water, provided 

 sufficient radiation is installed to aUow 

 for the lower temperature of the radiat- 

 ing surface in the case of hot water. 

 That this is a point in favor of hot water 

 seems well recognized by prominent 

 growers and florists, as the temperature 

 in the case of hot water reaches only 

 about 160 to 180 degrees and thus does 

 not burn the air or dry .up the hydro- 

 scopic moisture of the plants, and, on 

 account of the more piping being used, 

 gives a more even distribution. 



You cannot get something for nothing 

 out of boilers any more than any other 

 branch of human endeavor.

more:about expansion tanks 



Regarding the overflowing of expan- 

 sion tanks in hot water heating, let me 

 say that when the useless and dangerous 

 practice of connecting the tank with the 

 bottom of the boiler, or with the main 

 return pipe near the boiler, is discon- 

 tinued and a proper and safe connec- 

 tion made, the overflow of expansion 

 tanks and its consequent dangers will 

 "■ease. "Whether your tank is one foot 

 or twenty feet above the highest point 

 in the system, make connection with 

 the main flow pipe with not less than 1- 

 inch pipe, at or near the highest point
