"I have never noticed in your valuable journal any information touching a problem in hot-water circulation which came up to-day in our practice, and I write for information thereon.
"A customer of ours desires to locate a hot-water boiler some 6 or 8 feet distant from his stove, but does not want the hot-water pipe to run directly from the stove to boiler. The question is, can the hot-water pipe be run to the ceiling, and then down to the boiler and connect at the usual place, and cold-water pipe be run under the floor to the stove, and in this way have the water heat properly in the boiler ?
"If not as above, is there any way to arrange a boiler so that the water will heat properly 6 or 8 feet from the stove? "
[You may do as you describe, provided you put a "spud " on the side of the boiler high up for the hot-water flow pipe to connect with, and arrange a means of taking the air away from the top of the syphon formed above the boiler. An air-cock, or a very small pipe with a cock in it, run from the top of the syphon or loop to the hot-water pipe, rising a little all the time, so that the small pipe will not get air-bound, can be used. The cock in this pipe must be choked down so that only a very little water can cir culate by this way.
If you raise the boiler to as near the ceiling as possible on a suitable high stand it will help matters.
On principle we do not advise these arrangements; but where they are necessary we should proceed as above.]
