If you are looking for a water heater that has it all, our newest gas water heater delivers. Rheem^® Maximus^™ Super High Efficiency Gas Water Heater with LeakSense^™ has maximum efficiency covered with the latest in high demand water delivery and smart control.

Maximum Efficiency Means Maximum Energy Cost Savings

It’s the best when you find something that is top of the line, and you can take advantage of incentives.

Powerful Performance with Higher Output and MaxMode

With an efficient yet powerful burner, Maximus delivers up to 2.5x the hot water of a standard 50-gallon tank³. In addition, MaxMode^™ gives the water heater the boost it needs to keep up when demand is high, producing up to 15% more hot water. Even with houseguests, homeowners are covered.

Smart Control Provides Savings and Peace of Mind

Another Maximus perk is control through the EcoNet^® App. You can find the right balance of energy savings and hot water for your household’s needs with EcoNet app temperature control, operation modes, scheduling and energy usage tracking.
