Sometimes after a Baker system is ap-parently filled and circulates well, it willmake a round trip and on return take in2 or 3 gallons more water, which givesrise to a suspicion that there is a leaksomewhere. With the old-style safetyvalve, if the pressure in the heater got toohigh some of the steam and water wouldblow off. The new safety valves do notblow off; they break open, and must thenbe renewed. If a heater does circulatewell, it soon turns the water in the coilinto steam and blows out. Salt water is put in the heating system,because the freezing point of salt water isso much lower than that of fresh water,.

Brassis a better conductor of heat away fromthe water than iron; for that reason, anywater in a brass fitting will freeze quickerthan in the iron pipe next to it. It is a good idea to know when thepipes are full by measure. One hundredfeet of i}4-mch pipe holds about 7^/2 gal-lons of water. If a coach is 50 feet longinside and there are four rows of pipe oneach side, there are 400 feet to start add the cross-overs, the coils in theheater and the pipes to and from the ex-pansion drum, and you will get the totalamount. If much less than the properamount of water goes in. the air may betrapped so the water will not circulafe. that a coach will stand a cold snap with-out freezing the salt water, when withfresh w
