Does the Job

Submitted by LittleTank - 8/17/2020

This water heater does everything one would expect. Easy to adjust the temperature either on the product or using my phone. The mixing valve provides extra capacity if needed by allowing the customer to store water at a high temperature while still providing it at a low temperature if desired.
