Specifications side by side

How to choose the right one

1. Check the voltage requirement

   All listed LECLOC models operate on 120V power. This standard voltage limits each unit to single under-sink faucet applications. You cannot use these heaters for whole-house hot water needs. Verify your existing electrical outlet provides 120V before installation. Using a higher voltage source will damage the unit. The 3kW rating at 120V delivers instant warm water for low-flow tasks. Ensure your circuit can handle the load safely for reliable operation.

3. Identify control interface

   You can choose between digital or physical controls based on preference. The Best Overall model features a digital display for precise temperature monitoring.

4. Verify single-use design

   These heaters are designed for single under-sink faucet applications only. They provide instant warm water for one specific tap. You cannot split the output to multiple fixtures.
