Performance Series Tankless Electric RETEX - 04T, 06T kW
- Saves Space – Up to 98% smaller than a standard electric water heater
- Saves Energy – Zero standby heat loss when installed at the point-of-use
- Efficient Design – UEF up to .95 and advanced self-modulating technology only consumes the power needed to satisfy hot water demand
- Durable copper sheathed heating elements are replaceable, easy to maintain and improves service life
- Digital thermostatic temperature controls in 1-degree increments ranging from 80°F - 140°F (26°C - 60°C)
- Designed to be mounted in an upright position with the inlet and outlet water connections at the bottom of the unit for ease of installation
- Venting is not required to operate, simplifying the installation process compared to a gas tankless water heater
- Includes two optional 0.35 GPM aerators (flow restrictors) for optimal temperature output and performance
