In the kitchen of the National Home for Volunteer Soldiers at Hampton, Va., hundreds of gallons of hot water are required about meal time for cooking, dishwashing, etc , and usually only a small quantity during the intervening hours.

INDIRECT HEATING FOR A LARGE KITCKEN BOILER.

To meet this demand a tank A, about 4x16 feet, was provided and receives cold water through pipe B. An ordinary circular radiator R receives steam from the house-heating through pipe E and returns it through pipe R. This radiator is inclosed in a watertight iron jacket or drum D, about 2x5 feet, which is connected with boiler A by the hot and cold water circulation pipes H and C. Steam being turned on to radiator R, the water surrounding it is heated, and rises through pipe H to boiler A, while the colder water flows out through pipe C and replaces it in drum D, and so on. G is the hot-water supply and I is the emptying pipe.

The apparatus was made by Bartlett & Hayward, of Baltimore, Md., and is said to work satisfactorily, although it was desired to place the drum D in a vertical position instead of horizontally, as shown, and as was necessitated by the limited height of the room and the position of boiler A.
