Tankless Electric Water Heater 110V
After years of tinkering with various outdoor shower setups, I finally found what I consider the best electric water heater for an outdoor shower. This compact 110V tankless unit transformed my chilly garden hose rinses into a genuinely pleasant experience, proving that you don’t need a massive system for reliable hot water.
Pros
The instantaneous hot water is the star of the show. There’s no waiting for a tank to fill and heat; you get warm water in seconds. The digital display is incredibly handy for dialing in the perfect temperature before you step under the spray. I also appreciate its compact and efficient design, which made mounting it discreetly next to my shower post a simple task. The built-in safety features, like dry boil protection, gave me real peace of mind for an outdoor installation.
Cons
The main limitation is its flow rate. As noted, it’s not designed for a standard high-flow showerhead. To get comfortably warm water from my outdoor shower, I had to install a low-flow fixture, which creates more of a gentle spray than a powerful downpour. The installation instructions are thorough but require careful attention to details like vertical mounting and proper wiring to avoid error codes.
For anyone wanting to upgrade a simple outdoor rinse station or a camper shower, this heater delivers impressive value. It provides that crucial touch of comfort exactly where and when you need it, turning a basic utility into a small luxury.

EcoSmart ECO 11 Tankless Water Heater
The market is flooded with bulky, inefficient water heaters for outdoor showers, but the EcoSmart ECO 11 stands out by delivering instant hot water in a tiny, energy-saving package that mounts right where you need it.
Where It Excels
- It’s over 90% smaller and lighter than a traditional tank heater, making installation on an exterior wall simple.
- The self-modulating technology is far more energy-efficient than standard models, only heating water when the shower is on.
Where It Lags
- It has stricter electrical requirements (54A) than some plug-in outdoor shower heaters, needing a dedicated circuit.
- The flow rate is more dependent on your incoming water temperature compared to a powerful whole-house unit.
Pick this if saving space and cutting energy waste matters most for your outdoor setup. It’s perfect for a single showerhead where you want endless hot water without a giant tank. Just make sure your electrical panel can support it.

Eccotemp 110V Tankless Water Heater
The standout feature of the Eccotemp 110V tankless water heater is its compact and truly portable design. This sets it apart for outdoor use, as its small footprint and 110V requirement make it uniquely adaptable. Key specs include a 3000W power draw, a maximum output temperature of 131°F, and standard 1/2-inch NPT connections, all housed in an IPX4 waterproof casing.
Key Advantages
- The digital display with convertible temperature scale allows for precise monitoring in either Fahrenheit or Celsius, a handy feature for detailed control.
