Question:
Why the water is not hot?

1.The working current of our water heater is 25A-32A, and it require at least 1.5 square millimeters of wire. Please make sure that your circuit breaker can handle the 30amp, or it will not heat water.
2.The temperature is controlled by the size of the water flow. The Water Heater will be automatically energized when the water flow is more than 0.6 liters, and automatically turn off when the water flow is lower than 0.4 liters.
3.The heating temperature is between 30 and 55 degrees. If the water flow is large, the temperature will be low, and if the water flow is small, the temperature will be high.

Save water by eliminating the wait for hot water to reach the faucet. Simply tap into the water line and install the heater directly at the sink. No need for costly recirculating lines and pumps. And when you want to eliminate the wait for hot water but need more volume, install the Eco smart heater in-line with a larger hot water source, such as a tankless heater or a storage tank heater. Lightweight and compact, these units plug into a standard 110 volt outlet.
