When the valve is open, thewater will flow into the bath tub only, and when thevalve is closed, the water will flow into the washbasin. To insure there will be no backing up intothe basin when the water is wanted at the bath tub,the pipe to the basin should be given a slight up-ward pitch, so the water will have to rise an inchor more to discharge into the basin. Intelligentcare must be exercised in operating a heater whengas is the fuel, for if the cylinder becomes filledwith gas, there is liable to be a disastrous explosionwhen the gas is ignited. Instantaneous Water Heaters. 7Z Instantaneous heaters of this description arequite economical in the consumption of gas, butthey are limited in usefulness by the fact that theyhave the capacity to supply only a few fixtures,which must be located close Fig. i6 Another type of instantaneous water heater isshown in Fig. i6. In this heater the water doesnot come in contact with the products of combus-tion of the gas, as it does in the type of heaterpreviously shown, consequently the heated wateris much purer and can be used for cooking andother purposes, where the heated water will after-ward be taken internally. The water in this typeof heater has its temperature raised while floating 74 Hot Water for Domestic Use through a pipe coil, exposed to the flame of gasburners. In the illustration, the casing is shownremoved, to expose the interior construction of theapparatus, so the operation can be explained. Coldwater enters the coil through the valve e, and theflow is regulated by the valve handle h, which con-trols both the gas valve and the water valve, sothat gas
