The Rheem Tankless Electric RTE 13 is a compact, energy-efficient electric water heater offering you a continuous flow of hot water. By utilizing low-flow activation, the RTE 13 delivers a quick-responding point-of-use mechanism that provides the right temperature of water at your command. The modulating heat exchanger helps to improve the efficiency of the heating process, reduces energy expenditure, and ensures that youâ€™re not losing heat in standby mode.
Due to the water heaterâ€™s size, you shouldnâ€™t have issues installing the unit anywhere in your home. The model is 10 inches tall and 7 1/4 inches wide, so youâ€™re not competing for wall space. Itâ€™s lightweight and installation itself is pretty straightforward â€“ you donâ€™t even need to remove the cover. It needs 1/2-inch compression fittings to connect to your water source, and the electric water heater eliminates greenhouse gases itself, so no venting is necessary. You also don’t need to worry about a temperature and pressure (T&P) valve.
The Rheem RTE 13 Water Heater has a rugged brass and copper heat exchanger, and includes a pre-wired power supply cord. The LED display makes it easy to read the status of the heater (active versus standby mode), and you can control the temperature from the outside of the box as well. The tankless RTE 13 is a 13-kilowatt, 240-volt unit. You need a dedicated 60-amp breaker though.
Rheem offers an energy-efficient alternative to the traditional gas water heater, and the RTE 13 is ideal for quick-responding hot water for your sink. The point-of-use water heater is a small, simple unit thatâ€™s good at managing a single water source. Rheem backs the Tankless Electric RTE 13 with a 10-year limited heat exchanger and one-year limited parts warranty. It wonâ€™t do the job if youâ€™re counting on it for your shower or other high volumes of water flow, but as far as simply managing a sink, the electric water heater is effective.
