A. O. Smith Signature Series 240 Volt 24 Kilowatt 4-Chamber Tankless Electric Water Heater provides continuous hot water for up to 1 shower and 3 sinks (sink and shower calculations are based on a 0.5 GPM faucet and a 2.5 GPM showerhead in the southern zone) when sized appropriately. This makes it a good match for applications such as cabins, apartments, and small homes. Our small tankless electric water heater only heats water when needed for potential energy and money savings. Additionally, these models are wall hung, saving you valuable storage space.   Tankless electric water heaters typically require greater electrical supply capacity than standard tank-type models. Please ensure your home's power supply can support this model and that you have enough space in your breaker panel. A. O. Smith's electric tankless water heater includes a soft start to produce a softer electric draw when powering on, reducing light dimming. This model requires 240 volts, 100 amps, 2 x 60-amp double pole breakers and 6 AWG wire size.  Call 1-877-GOLowes to get this water heater installed.
