Why is my Airthereal EVT-9K not getting hot enough?

  Christian GarciaAug 16, 2025
  If your Airthereal Water Heater isn't heating the water enough, consider these potential causes: * The user temperature setting might be too low. Try turning up the temperature setting on the unit. * The water flow rate might be too high. Depending on the incoming water temperature and the power output of your model, reduce the water flow. * The voltage might be less than 240 volts. Note that the set voltage of the water heater is 240v, and a lower voltage reduces heating power, possibly requiring a larger power model. * You might be mixing too much cold water. Reduce the amount of cold water mixed, and adjust any anti-scald features on your faucet.
