¹Comparison of a 40 and 50-gallon Maximus to a standard atmospheric gas tank of like capacity with minimum efficiency. ²Recovery comparison of Maximus to atmospheric and PV/conventional vent gas tanks. ³Continuous hot water is dependent on inlet water temperature, tank water set temperature and model. ⁴Wi-Fi broadband connection and EcoNet App required; connection between water heater and app are dependent on external factors beyond Rheem’s control. ⁵Based on AOC (annual operating cost) comparison of 40- and 50-gallon Rheem Maximus Gas Water Heaters to standard gas water heaters of like capacity with minimum efficiency. ⁶Water leaks from the heater only, as tested across scenarios including a minimum of 5.5mL/hr volume leak rate, using most common installation scenarios. Time starts when leak begins and ends when sensor alarm is triggered. ⁷Applies to models with auto shut-off valve installed only. Testing under a vacuum lock using 50-gallon tank, no expansion tank, average tank pressure of 40 psi, assuming no additional faucets are opened. ⁸Wi-Fi broadband connection and Rheem Contractor App required; connection between water heater and app dependent on external factors beyond Rheem’s control. ⁹Compared to standard atmospheric gas water heater, not to exceed 75,000 BTUs.
