The Richmond® Essential® RMTEX-04 is a 3.5 kW tankless electric water heater ideal for low flow point-of-use applications. Typically this unit is installed at the point-of-use and hard wired to 120 V requiring a 30 A breaker. Richmond® Essential® tankless electric water heaters offer a continuous, endless supply of hot water. A lower kilowatt unit can provide hot water on demand for single or multiple point-of-use applications while a higher kilowatt unit could provide hot water for a whole house depending on the inlet ground water temperature. Tankless electric water heaters save space, save energy, save money, and require no venting. The sleek, compact size, 90% smaller than a tank, allows you to save space and place the unit wherever you want, including under a sink. Tankless units only draw energy when hot water is flowing, while traditional tanks are constantly drawing energy to keep the water in the tank at the desired temperature.
