A.O. Smith Signature Series 240-Volt 18-KW 3.5-GPM Tankless Electric Water Heater

Get plenty of continuous hot water for 1 shower and 1 sink (sink and shower calculations are based on a 0.5 GPM faucet and a 2.5 GPM showerhead in the southern zone) by installing this A. O. Smith Signature Series 18kW tankless water heater. Perfect for applications such as cabins, apartments and small homes, this unit only heats water when it's needed for potential energy and money savings. This wall-mounted water heater also saves 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 75 amps, 2 x 40-amp double pole breakers, #8 AWG wire size and 240-volt water heater wiring required for this model and that you have enough space in your breaker panel.
