Hot water for domestic use : a complete guide to the methods of supplying and heating water for domestic purposes, giving each step to be taken and explaining why it is done . pe ofwater heater has its field of usefulness and givesgood service when installed. Gas water heaters of the other type are attachedto the range boiler, where they take the place of a 70 Hot Water for Domestic Use waterback; and automatic instantaneous water heat-ers are designed to supply hot water to the entirebuilding, day or night, without any care or atten-tion from the inmates, and with a consumption ofgas only when water is being heated. Instantaneous Water simple apparatus for heating water instantan-eously with gas is shown in Fig. 15. In this illus-tration part of the cas-ing is removed, so theinterior constructionmay be seen and theoperation apparatus willnot heat water underpressure, but onlywhen released frompressure and flowingover the plates bygravity. Owing tothis fact, the heatermust be placed at ahigher elevation thanthe fixture it is intend-ed to supply with hotwater. The operationof the heater is as fol-lows: A special gasthat gas cannot be. Fig. 15. cock a is so constructed Instantaneous Water Heaters 71 turned on to the heater without also turning on thewater valve b, thus preventing the overheating orburning of the water heating plates. A pilot lightc is always burning, so that as soon as the gas andwater are turned on the gas enters the burners d dfrom the ring e to heat the plate surface. When thewater is turned on it flows through the valve hand up through the standpipe shown in the centreof the cylinder, to near the top of the apparatus,where it is discharged through a spray nozzle andfalls in a thin sheet, which spreads out over theentire heating surface i. As the water flows overthis thin metal surface, it absorbs heat from theflames and hot gases within, so that by the time itreaches the bottom of the compartment and flowsout of the spout
