We’ve compared the Rheem 18kW 240V Tankless Electric Water Heater in Gray to gas models and found it delivers impressive, on-demand performance. Switching from a tank system, we appreciate its seamless integration into our 240V setup, eliminating standby heat loss and saving energy in the long run. Its sleek, gray finish blends into our bathroom’s modern aesthetic, adding a touch of sophistication without compromising efficiency.
