Self-Cleaning

Rheem Professional Series units include a self-cleaning system that uses a water spiraling process to reduce sediment build-up in your tank. That means less frequent need for flushing and a longer life for your unit.

Thicker Lining

Rheem Professional Series units include a thicker porcelain-enamel lining than the lining in Performance units, which helps the unit to better resist corrosion. This results in a longer-lasting hot water tank.

Higher Quality Valves

Performance Series units found in stores include a gas valve with a plastic case, and a plastic drain valve. Professional Series units carried by The Bosworth Company include a gas valve with a metal case and a brass drain valve.
