Cons
Electrical Requirements
The requirement for three double throw 40 amp breakers and 8 gauge wire for installation can be a drawback, as it necessitates a significant electrical capacity that not all homes may have readily available.
Dependence on Electrical Power
Like all electric tankless water heaters, the RTEX-24’s operation is contingent on having a reliable electrical supply. In the event of a power outage, hot water availability is compromised.
Initial Cost Outlay
While the unit itself is cost-effective, the total cost of installation, including necessary electrical upgrades and additional components, can be substantial. This initial investment may deter some potential users.
Delay in Hot Water Delivery
Some users have noted a slight delay in hot water delivery to faucets, especially in larger homes where the points of use are spread out from the heater.

The Rheem RTEX-24 Electric Tankless Water Heater stands out for its efficiency, space-saving design, and the convenience of continuous hot water. It represents a significant improvement over traditional tank heaters, with the potential for energy savings and enhanced user experience. However, potential buyers should consider the electrical requirements, initial installation cost, and maintenance needs.
