While the heat losses from an ordinary kitchen boiler witha connection from a water front heated by a coal fire may becomparatively unimportant, there are other conditions which make such losses a matter worthconsideration. In tanks of largercapacity than those used in theaverage household, such losses byradiation become important andthe usual method of avoiding themis to cover the tank with a non-conducting covering of asbestosor some such substance. Smallerboilers may have a covering ofsimilar nature if desired and spe-.

Another method is to use a lagging of closely fittedboards bound with metal bands. Where the boiler is heated bygas and a thermostatic control of the valves is used such pro-visions are economical, as the constant radiation from the boilerwhen uncovered will cool off the contents and cause the gasvalve to open more frequently than the ordinary demand of thebuilding would call for. Where such coverings are dispensedwdth, however, it is possible to retard to some extent the radia-tion by using the proper paint to finish the boiler with and aknowledge of the effects
