GIVIMO 27kW Tankless Electric Water Heater vs Eccotemp SHiE-27 Tankless Water Heater

Buy the Eccotemp SHiE-27 for a whole-home or multi-fixture install where the electrical panel is limited or you want app and voice control. Buy the GIVIMO if you need a cheap point-of-use unit under a sink for handwashing or a single shower and your panel already has the capacity. The Eccotemp is the better-engineered product: adjustable amperage from roughly 11 to 27 kW, 4.5 GPM, ETL and FCC listing, and a smart app with scheduling and diagnostics. The GIVIMO is a basic 240V unit with a touchscreen and child lock, but it carries only a 90-day warranty and is not safety listed.

• Choose the GIVIMO if you want a simple under-sink point-of-use heater for one sink or shower and you already have the breaker capacity for a 27 kW load.
• Choose the Eccotemp SHiE-27 if you want one heater to serve up to three fixtures, need to fit an existing panel without an upgrade, or want app, schedule and Alexa/Google control.
