  • Energy Conservation: When not being used for a lengthy period of time, conserve energy by reducing the temperature setting either manually or through the Eccotemp App.

  • Freeze Protection: If you plan on not using the water heater for an extended period, unplug your water heater and drain it to protect against freeze damage.

Regular Maintenance

Proper maintenance ensures your water heater provides years of dependable, trouble-free service. Follow these maintenance steps:

  • Periodic Inspection: Check the pipe connections every 6 months.

  • Pressure Relief Valve: At least once a year, lift and release the lever handle on the pressure relief valve, located between the hot and cold water lines. Ensure the valve operates freely by allowing several gallons to flush through the discharge line to an open drain.

  • Safe Operating Environment: Inspect the area around the water heater to ensure it is clear and free from any objects that could cause damage. If you notice any damage or denting, contact a service professional to verify proper operation.

  • Operation Warnings:

    • Do not operate the water heater if you suspect something is wrong.

    • Do not allow children to operate or handle the water heater.

Notice: If the pressure relief valve on the hot water heater discharges periodically, this may indicate a problem in the water system. Contact your water supplier or plumbing contractor to address this. Do not plug the relief valve outlet.

Draining & Storage

When draining your water heater, follow these steps:

  1. Unplug the water heater.

  2. Open a hot water faucet to let hot water run out. Allow water to flow until it is no longer hot.

  3. Turn off the cold water supply to the water heater.

  4. Close the hot water faucet.

  5. Disconnect the water heater from both the hot and cold water connections.

  6. If possible, siphon out any remaining water.

  7. Carefully detach the water heater from the wall (if applicable).

  8. Tilt the water heater to drain any remaining water out of the heater.
