Eccotemp SmartHome Adjustable 11-27kW Electric Tankless Water Heater - 1779610900135_72

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.

A: It is suitable for apartments, condos, cabins, and full family homes, especially where space-saving and on-demand hot water is preferred. 

Maintenance Tips

• Descale every 6–12 months (more often in hard water areas) to prevent heating element scaling and flow loss
• Clean inlet water filter regularly to maintain stable flow and prevent error codes
• Check electrical connections periodically for tightness, overheating signs, or corrosion
• Inspect breaker and wiring load capacity to ensure safe operation at 11–27kW demand
• Maintain water pressure within recommended range for consistent activation and heating performance
• Flush system before peak usage seasons to reduce sediment buildup
• Set temperature around 120°F to minimize scaling and improve efficiency
• Ensure proper ventilation/clear space around unit even though electric (for heat dissipation)
• Test SmartHome connectivity & diagnostics for alerts and performance monitoring
• Annual professional inspection recommended for wiring, heating elements, and safety checks
