Rheem’s Water Star works with a continuous hot water system to deliver six-star energy-efficiency.

Rheem Water Star

Rheem’s Water Star is a water-saving device suitable for all brands of continuous flow water heaters. It’s the easy way to have fast hot water, minimize water wastage and reduce energy usage in the home.

Water Star works by capturing cold or warm water from the continuous flow water heater at start-up, while releasing already-hot water for instant use. The same size as a continuous flow water heater, Rheem Water Star’s compact tank has a small electrical element keeping water permanently hot. The system delivers the equivalent of six-star energy efficiency when combined with a five-star continuous flow water heater.
