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 . ooking, thisrequirement is not so necessary, although even thenit is desirable. 86 Hot Water for Domestic Use Heating Large Bodies of gas water heaters are to be used forheating large tanks of water, that is to say, tanks of100 gallons and over, the multiple type of heater must be used. A compactmultiple gas water heat-er, in which three heatersare used, in connectionwith one large hot watertank, is shown in Fig. this illustration, part ofthe lower part of the hotwater tank is broken awayto show the location of theheaters, and the manner ofconnecting them to theboiler. As may be seen,the heaters are set clover-leaf shape, and are snuglynested in cavities formedwithin the body of the boil-er. From these, cavities,vent pipes extend to abovethe top of the tank, so thatthe products of combustioncan escape. If they couldnot, no hot water could be produced, for the gaswould refuse to burn in the absence of air or good feature of the nesting of gas water heaters. Fig. 18. Compact multipie gas water heater. Thermostatic Control 87 within the boiler, as is done in this case, lies in thefact that there is no loss of heat by radiation fromthe outer surface of the heater casings as therewould be if these casings were exposed to the at-mosphere. AH heat of combustion, even to the ex-haust heat in the gases passing up through the ventflues, can be transmitted to the water, so that en-closed heaters of this type develop the maximum ef-ficiency, so far as utilizing all heat contained in thegas is concerned. It will be noticed that multiple connections con-sisting of three-way fittings are used to connect theflow pipes from the bottom of the boiler to the bot-toms of the heaters, and a like connection is usedfor connecting the return pipes to the top of the boil-er.
