A.O. Smith Signature Series 240-Volt 28-KW 5.5-GPM Tankless Electric Water Heater
Simplify your morning routine with this A. O. Smith tankless water heater that delivers enough continuous hot water for 1 shower and 4 sinks (based on a 2.5 GPM showerhead in the southern zone) when sized appropriately. This Signature Series electric tankless hot water heater makes a great choice for applications such as cabins, apartments, and small homes since the unit only heats water when it’s needed for potential energy and money savings. This small tankless electric water heater also mounts on the wall, saving you valuable storage space, and the soft start design enables a softer electric draw when powering on, reducing light dimming. Keep in mind that professional installation is recommended for a tankless hot water heater since these units typically require greater electrical supply capacity than standard tank-type models. Please ensure your home can support the 116.7 amps, 2 x 60-amp double pole breakers, #6 AWG wire size and 240-volt water heater wiring required for this model and that you have enough space in your breaker panel. Call 1-877-GOLowes to get this water heater installed.
