ELECTRIC ELEMENT
1. An AC electrical heating coil that is immersed in water.
ANODE PROTECTION - WATER HEATER
Each Suburban water heater is equipped with a replaceable anode rod. The sacrificial anode, equalizes aggressive water
action providing cathodic protection for the tank. The anode rod is a very important factor in tank life and should only be
removed for inspection or draining. Replacement of the anode rod is recommended when consumption or weight loss is
greater than 75%. With regular inspection and replacement of the anode, tank life can be greatly extended. Frequency of
anode replacement will vary depending ont he water conditions and usage. Sediment on the bottom of the tank forms a
layer of insulation between the gas burner and the water. The sediment slows heat transfer and overheats the tank bottom.
Overheating weakens the steel and damages the glass lining, shortening the tank life. In addition, it lowers the energy
efficiency of the tank.
