I HAVE A 32 GALLON OIL-BURNER HOT WATER HEATER.
WHAT IS THE MOST EFFICENT SETTING FOR THE HI/LO TEMPERATURES?
CURRENTLY AT HI: 140 & LO: 120
I LOWERED IT FROM 180/140 TO SAVE MONEY.
SHOWERS NOW USE ABOUT 90% HOT WATER/10% COLD.
PREVIOUSLY I WOULD SAY, 50% HOT/50% COLD.
SHOULD I HAVE CHANGED IT FROM 180/120 INSTEAD?
WHAT DO THE SETTINGS MEAN:
**********
DOES THE UNIT HAVE 2 HEATING ELEMENTS? ONE HI, ONE LO?
OR IS LO WHEN THE UNIT TURNS ON & HI WHEN THE UNIT SHUTS OFF?
