Expert Tips for Maximum Value

Tip #1: Optimize Your Gas Line

Ensure you have a 3/4 inch gas line installed for optimal performance. An undersized gas line will throttle the unit’s BTU output and reduce its efficiency.

Tip #2: Use the App Scheduling Feature

Set the water heater to a lower temperature overnight or when you are away from home. This can lead to significant energy savings over time.

Tip #3: Install a Water Softener

To protect the 100% oxygen-free copper heat exchanger and extend the lifespan of your unit, consider installing a whole-house water softener if you have hard water.

Tip #4: Insulate Exposed Pipes

If you live in a cold climate, properly insulate the hot water pipes running from the outdoor unit into your home to minimize heat loss and prevent freezing.

Tip #5: Clean the Inlet Filter Regularly

Debris and sediment can build up in the water inlet filter, reducing flow rate. Cleaning it every month is a simple maintenance task that ensures peak performance.

Tip #6: Set the Right Temperature

We recommend setting the temperature to 120-125 degrees Fahrenheit. This provides a great balance of comfort, safety, and energy efficiency for most households.

Tip #7: Consider a Recirculation Pump

If your bathroom is far from the water heater, adding a recirculation pump helps deliver hot water instantly, reducing water waste and wait time.

Common Mistakes to Avoid

1. Mistake: Attempting a DIY installation. → Solution: Always hire a licensed professional to handle gas and water connections for safety and warranty compliance.

3. Mistake: Using an undersized gas line. → Solution: Verify that your gas line can supply enough BTUs to the unit. An upgrade to 3/4 inch pipe is often necessary.
4. Mistake: Neglecting to winterize. → Solution: Even with electric anti-freeze, drain the unit and insulate pipes if you live in an area with extended periods of freezing weather.
