Therefore, I added here a guide to avoid any adverse circumstances:

How to Turn On Electric Tankless Water Heaters?

Start with turning off the circuit breaker—a primary source of current supply and turn on the warm water taps connected to the unit. Let them run for up to two minutes so that air purges through pipes. Ensure to not open water faucets that are not serviced by the following water heater. You have to reverse the first step: turn on the circuit breaker and turn off the open, warm water valves.

The advanced tankless water warmers have the main dial with several figures, through which you can regulate the water temperature. According to the United States Energy Department, 120 degrees Fahrenheit is an ideal warmth reading as it reduces electricity costs and resists scalding.

Your electric tankless water heater has all-set now, so let’s take a quick check to ensure everything is working fine. For this, place a large bucket under the bathtub valve and turn the faucet on at maximum for a minute. Then measure the water quantity in the tub and shut the valve for a minute or two. After two or three gallons, you need to repeat this step to check the water temperature properly.

How to Turn On Gas Tankless Water Heaters?

The process starts by turning off the primary circuit breaker that supplies current to the water heater. You might be thinking about why we deal with circuit breakers in gas heaters.

Then, please find the primary gas faucet and shut it off by rotating clockwise. Make sure that gas is entirely cleared from valves: this step takes at least five or ten minutes.

After that, you need to reciprocate those steps: turn on the circuit breaker and rotate the gas supplier anti-clockwise “towards ON state.” Find the main power switch and turn on the unit; your tankless warmer starts functioning now! It’s time to set the temperature at 120 degrees Fahrenheit by regulating the arrows. Some remote control models allow you to handle setup from your bedroom; isn’t it so convenient? Once you have done that, take a test to check your heater!
