Best 13kw tankless water heater

The water heater is an amazing invention that makes it easy for us to get warm and hot water in cold environments. Having a lower electric-consuming 13kw tankless water is a great option because it provides value and it does the job. So here in this guide, I have listed 3 tankless water heaters for you and these are my recommendations.
Starting with my number 1 pick:

  1. EcoSmart ECO 11 Electric Tankless Water Heater, 13KW at 240 Volts with Patented Self Modulating Technology
  2. Rheem 240V Heating Chamber RTEX-13 Residential Tankless Water Heater, GRAY
  3. Eemax EEM24013 Electric Tankless Water Heater, Blue
  4. Eemax HA013240, Stainless Steel

1. EcoSmart ECO 11 Electric Tankless Water Heater, 13KW at 240 Volts with Patented Self Modulating Technology

Features List:

This is a good lightweight option if you are looking for providing hot water to a bathroom, small sink, office breakroom, and other point-of-use or low-flow applications, and is good for indoor uses. This water heater is configured for climates where the temperature of the water is 67F (19.4444C) degrees and above.

The Temperature range of EcoSmart ECO 11, 13kw is 80-140°F (26.6667C to 60C)

You can also use this water heater in colder climates for low-flow application or under the sink. It’s easy to control the temperature setting with a knob and a digital display with increments of 1 degree.

Depending on the inlet water temperature, it can provide between 1.3 and 3.1 gallons per minute. Also, be careful as this is a small unit designed to be used for regular tasks as some users have reported that this unit catches fire so be sure to ask Plumber and a professional (Licenced Electrician) to help you install this and use the instructions carefully to avoid any unpleasant circumstances.

This heater requires one 60 amp double pole breaker and 240 volts. Usually, RVs do not have sufficient amperage. And for RVs choose a different lower flow rate tankless water heater that is specifically designed for RVs. Or If your RV can provide 240V and 60 amps then the ECO 11 should work fine. But usually, they only have 120V, which cannot provide enough heating to give a hot shower.

The Eco 11 cannot be used for radiant heat floor systems because they require the hydronic heater to have 180°F output temperatures. The maximum output temperature for the Eco 11 is 140°F.

The internal electrical components and case of this unit are not sealed against moisture intrusion from the outside.

Be sure to ask the manufacturer or seller before purchasing to avoid any confusion ahead.

2. Rheem 240V Heating Chamber RTEX-13 Residential Tankless Water Heater, GRAY

Features List:

This is also a 13kw and 240 Volts electric water heater that provides good quality and decent enough hot water from 0.3 to 4.8 gallons per minute. The digital thermostatic control with LED display also gives you easy control over the temperature so you can adjust the water temperature easily.

The RTEX-13 requires 1x 60A @ 240V breaker / 6 AWG recommended wire size. this unit from Rheem requires 240-volt power, and if you want to install it on an RV then Rv should support 240 Volts/60A power requirements.

If you have questions about this be sure to ask the seller before purchasing so you can get the complete information and requirements according to your needs.
