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 . k 07 Wood ashes 61 Glass 05 Stone 02 * Combustible and sometimes dangerous. It often is desirable to cover hot water pipes tokeep them from radiating heat, or to prevent themfrom becoming frozen. Further, a covering ma-terial is sometimes desired to prevent pipes fromsweating during warm weather.

A tableshowing the relative value of non-conducting ma-terials will be found on the preceding page. Principle of Heating Water in a Range The principle by which water in a kitchen rangeboiler or hot water tank is heated from a water back or water heater,located some distanceaway, is shown by areference to Fig. this apparatus apipe is taken from thebottom of the tankand extended out distance in ahorizon-. ~^___jM Fig. 3. ^ tal d i-recti o n,wherei t ter-minate s in a return bend. From this return bend anotherpipe is extended up to and connected to the side ofthe tank, thus forming a continuous loop. If heatbe now applied to the return bend as shown in the 24 Hot Water for Domestic Use illustration, the water within will become heated,become lighter in volume and thus be displaced bya column of water of similar size within the movement of water, once started, will continueas long as heat is applied to the return bend. Tostart and maintain such a circulation, however, thepipe leading from the return bend to the side of theboiler must have a rise all of the way. Should thispipe become trapped in any way, the circulation ofwater would become impeded or entirely stopped,depending on the depth of trap, and if
