18kW Electric Tankless Water Heater 240 Volt, ETL certified HAI-180ET

This ThermoMate tankless electric hot water heater for continuous hot water, 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 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 water heater since these units typically require greater electrical supply capacity than standard tank-type models. Please ensure your home can support the 80Amp breaker (2 Sets of Double-pole 40AMP Breakers), wire gauge 2 x 8AWG and 240-volt water heater wiring required for this model and that you have enough space in your breaker panel.
