Maintenance - Rheem RHP-2805 Series Owner's Manual And Installation Instructions

Reducing the temperature setting of the water heater can alleviate the scale deposition to the inner
surface of the tank cylinder, and so increase the life expectancy of water heater.
Water which is easy to scale may be treated with a water softening device to reduce the saturation
index of the water.
