Discover the Eccotemp SHiE-27 Smart Home Electric Indoor Tankless Water Heater
The Eccotemp SHiE-27 is the first all-in-one, smart electric tankless water heater designed for complete installation flexibility, energy control, and modern smart home integration. Using our patent-pending Tuner™ feature, you can now adjust the smart electric tankless water heater’s output across a wide range , from as low as 10 amps to 113 amps, or approximately 2.4 kW to 27 kW, without the need for costly panel upgrades.
This unprecedented flexibility means the SHiE-27 adapts to any size breaker setup. Whether you're working with 3x 15Amp breakers in an older home or a full 3x40amp layout in a modern build, the smart electric tankless water heater intelligently adjusts to your available capacity. You control the settings directly through the Eccotemp Smart App, eliminating the limitations of fixed amperage heaters and making high-capacity installs optional not required.
The SHiE-27 is the only electric tankless water heater on the market with this level of digital amperage management, Triac-based circuit control, and app-enabled tuning making it a must-have for today’s energy-conscious, tech-enabled households.
Eccotemp Smart App
Take control of your water heating experience with the Eccotemp Smart App. Enjoy convenience, efficiency, and precision with the following features:
Tuner™ Control: Adjust the amperage draw anywhere between 10 and 113 amps, based on your panel’s capacity. Control each of the three independent Triacs, which function like digital breakers, to scale power as recommended (11kW, 18kW, or 27kW configurations).
Timer: Set hot water durations for each use to save energy and tailor comfort.
Scheduler: Program your smart electric tankless water heater to turn on/off during specific hours or days.
Statistics: Track your real-time energy and water consumption, and view historical usage and estimated cost savings.
Temperature Control: Set and save custom water temperatures remotely.
Wi-Fi Quick Connect: Enjoy a fast, secure connection to your home network for seamless mobile app control.
Advanced Diagnostics: Monitor heater and network performance with self-diagnosing error detection and guided troubleshooting.
Coming Soon: A future firmware update will activate AI Auto-Tuning, allowing the SHiE-27 to intelligently learn your usage habits, optimize energy efficiency, and dynamically adjust amperage to avoid overloading your breakers, all without manual input.
All-In-One Flexible Installation
At the core of the SHiE-27 is its Triac-based digital breaker system. Each of the three Triacs connects to a separate 40A breaker. You can activate one, two, or all three Triacs depending on your needs and capacity. This allows you to:
Install the smart electric tankless water heater on any size breaker setup
Run the smart electric tankless water heater on as little as 10 amps in reduced-output mode
Expand power later - no hardware changes required
Fine-tune energy draw across individual breakers to prevent overloads
This flexibility makes the SHiE-27 ideal for new homes, renovations, off-grid setups, or properties where electrical upgrades are cost-prohibitive.
Smart Voice Commands
Live smarter with hands-free operation. The SHiE-27 is compatible with Amazon Alexa and Google Home, enabling effortless voice control.
Try:
“Alexa, set my water heater to 110 degrees”
“Hey Google, turn off the water heater”
This feature is perfect for everyday convenience, accessibility, and energy efficiency.
Sleek Style and Space Saving
Modern in every sense, the SHiE-27 features a sleek black tempered glass front panel and a compact wall-mounted design. It complements contemporary decor, saves space, and installs easily with ¾” NPT water connections. Whether you're outfitting a large home or a small space, the smart electric tankless water heater fits seamlessly into your lifestyle.
Efficient On-Demand Solution
The SHiE-27 produces instant, on-demand hot water only when you need it. With a flow rate of up to 4.5 GPM and an activation flow of just 0.5 GPM, it can support up to three applications simultaneously, such as a shower, sink, and washer.
Power Draw and Performance Based on Location
The performance of the SHiE-27 Smart Electric Tankless Water Heater is influenced by several key factors — most notably your geographic location, incoming water temperature, and desired output temperature.
Because the SHiE-27 heats water on demand, colder regions where groundwater temperatures are lower will naturally require more power to achieve the same hot water output compared to warmer climates.
Example:
In southern regions (e.g., Florida, Texas, southern California), incoming water may be around 65–75°F, allowing the SHiE-27 to deliver full performance — up to 4.5 GPM — even at moderate power settings.
In northern regions (e.g., New York, Minnesota, Canada), groundwater may arrive at 35–45°F, requiring higher amperage (closer to the 27kW / 113A range) to raise the temperature to a typical 105–120°F usage level.
What This Means for You:
Colder climates = higher power draw required for the same flow rate
Warmer climates = more efficient operation at lower amperage
Flow rate and performance may vary based on your specific electrical settings and water conditions
The SHiE-27 gives you the flexibility to fine-tune power based on real-world needs — allowing for safe installation even in homes with limited capacity, while offering maximum output in homes with full breaker availability.
To get the best performance in your area, use the Tuner™ feature in the Eccotemp Smart App to set your amperage based on your local water temperature, flow rate needs, and household demand.
Absolutely! Here’s a well-integrated section you can add to your product description that explains the use of the included wireless remote, the default power configuration, and how users can operate the SHiE-27 without using the app or smart features:
Simple Operation with Included Wireless Remote
While the SHiE-27 is packed with cutting-edge smart home features, it’s also built for simplicity and flexibility.
Every SHiE-27 comes with a wireless remote control that allows you to:
Power the smart electric tankless water heater on or off
Manually adjust the water temperature
View the current set temperature — all without accessing the app or using voice control
This makes the SHiE-27 perfect for users who prefer a more traditional interface or for properties where app-based control isn’t needed.
Whether you're installing in a rental unit, vacation home, or simply want the freedom to operate it without a smartphone, the wireless remote provides a quick and easy way to control your water heater from anywhere within range.
Default Power Configuration
Out of the box, the SHiE-27 is configured as a 27-kilowatt smart electric tankless water heater, requiring three 40-amp double-pole breakers (3 x 40A @ 240V) for full performance.
This setup delivers the maximum flow rate of up to 4.5 gallons per minute, ideal for running multiple hot water applications simultaneously.
However, thanks to the built-in Tuner™ feature and Triac control system, you can reduce the power draw to match your available breaker setup — adjusting from full performance down to as low as 10 amps — all without additional hardware.
Whether you're going smart or staying simple, the SHiE-27 gives you complete control over how it's used.
