Rheem RTE 13 Tankless Water Heater Reviews

On-demand tankless water heater is trending and Rheem RTE 13 is only one among the few models that successfully draw the majority of the consumers’ attention, thanks to its affordable retail price. The manufacturer’s brand is probably not as popular as Bradford White and AO Smith but in terms of quality, its products are nicely competitive.

You will not find any flashy LCD display on its control panel. Rather, you’re provided by a plain knob controller assisted by a couple of LEDs that function as indicator for the active element and standby mode. Overall construction seems pretty solid as well, thanks to the rugged brass and copper build. If you’ve been eyeing Rheem RTE 13 tankless water heater, this review should help you decide in the end.

Pros

Very few electric tankless water heaters have the necessary efficiency to bear a rating from Energy Star but Rheem RTE 13, despite its low end appearance, manages to get one. If anything, this only shows how much the company dedicates itself to deliver quality products to consumers’ market. Although its size is pretty compact (only 7.5-inch), this heater is intended only for indoor installation. Speaking of installation, this heater can’t be any simpler. Simply link the unit to your plumbing and electrical fixtures and you’re good to go. Note that it requires a 60 double pull breaker, though.

The control panel on Rheem RTE 13 tankless water heater isn’t provided with a LCD display. The water temperature can be adjusted via the turn knob. A couple of LED indicators sit nicely with the knob to inform homeowners regarding its active element and its current mode. The unit housing doesn’t feel reliably strong at hand but we’re glad to find that the heat exchanger is made of solid brass/ copper. The starting price only revolves around $200 but for that, you are only protected with 1-year warranty for the parts. For the heat exchanger, on the other hand, the company promises 10-year warranty.

Cons

As an electric model, Rheem RTE 13 isn’t geared toward whole house operation. With maximum flow rate of 4 gallons per minute, you can only open two showers with no additional faucets at the same time. Pushing it a little further and you will end up with unpleasant flow of water. Still, we’re happy to know that the company advertises it as point-of-use unit rather than making fake claim just to kick the sales number up a notch.

Conclusion

For an electric tankless water heater, this model has a lot to be praised. Not only has it been approved by Energy Star, it also comes at a very reasonable price. On the other hand, it’s not suited to be whole-house water heater. In other words, you only find Rheem RTE 13 satisfying if your attention is finding an additional heater to complement your existing unit.
