The accompanying illustration shows a kitchen water heater as fitted up in the residence of W. C. Andrews, 854 Fifth Avenue, New York.

The upper part of the illustration represents the boiler in the basement, while the lower part shows the water heater in the celler. W is a hollow copper cylinder about 6 inches long, the end which is inserted into the boiler being closed up so as to make it water-tight. The end projecting from the boiler is open so as to admit a thermostat.

When the heater above is not required the valves B E and F are closed and the valves S and H are opened, and it will heat from the range. To use both heater and range open valves B E and F and close valves S H.

A designates the Croton supply to kitchen sink and butler's pantry sink; B, tank supply to hot-water heater in cellar; the valve on this pipe is to be shut when hot water is not in use, and to be opened when in use; C, intermediate pipe; T, check valve; D, Croton supply to boiler; E, inside boiler or tank circulation, to be kept open when heater is in use, and to be kept closed when not in use; F, connecting pipe for boiler and heater, to be kept open when heater is in use, and to be closed when heater is not in use; G emptying pipe for outside boiler; H, inside boiler or tank circulation, to be kept closed when heater is in use, to be kept open when heater is not in use; I, emptying pipe for inside boiler; J, Croton circulation for inside boiler; K, tank or inside circulation; L, hot water from outside boiler to supply lower floor. M, hot water from inside boiler of tank, to supply upper floor; N, tank supply to inside boiler, or to heater in cellar; O, hot-water supply to kitchen sink; P, Croton supply to kitchen sink; Q, hot-water supply to butler's pantry sink; R, Croton supply to butler's pantry sink; S, tank supply to the inside or high-pressure boiler, to be kept closed when hot-water heater is in use, and to be kept open when heater is not in use; U, steam supply to boiler; V, return from boiler; W, thermostat.

KITCHEN BOILER IN A NEW YORK CITY RESIDENCE.

In this case the boiler in the basement is in a small room adjoining the kitchen. The walls are lined with Italian marble. The boiler and fittings are all nickel-plated; the pipes are of tinned brass. The pipes are hung about 4 inches from ceiling on nickel-plated plates and hangers, and where pipes go through the wall, floor or ceiling there is a nickel-plated flange, all in one piece, through which the pipes are put.

We have here a self-acting water heater (connected with the kitchen boiler), heated, by steam, and regulated by electricity, and the temperature of water is said to never vary beyond 3 degrees. It is thus claimed to be a great improvement on the old hot-water heater, heated by a coal fire, and requiring constant attendance to maintain a proper temperature, besides entailing dust and danger from a fire in the cellar.

The reason that this heater was put in was that after taking one or two baths, the hot water in the boiler was used up, and consequently considerable time would elapse before another supply was available. In this case, however, the thermostat is so set that while drawing water for a bath, the cold water, which has displaced the hot water, is heated up again in a comparatively short time, because as soon as the temperature of the water drops 3 degrees the thermostat opens valves, admitting steam to the interior coil shown.

Mr. W. C. Andrews has had one in his residence at 2 East Sixty-seventh Street, New York, for two years, where it is said to have given every satisfaction.

Messrs. Lamb & Rich, of New York, were the architects, and the arrangement described was put in by Mr. George A. Pace, of New York.
