Questions and Answers

    Why is the water too hot in my Rheem CRTGH-95X Water Heater?
    • N
      Natalie HayesAug 18, 2025
      If the water from your Rheem Water Heater is too hot, it might be due to several reasons. The temperature setting could be too high; try decreasing it using the remote control. Alternatively, the water shut-off valve may not be fully open, so check and ensure it's completely open. If only a small amount of water has been heated, increasing the hot water flow at the faucet can help by allowing more water to flow through the heater.

    Why is my Rheem Water Heater water not hot enough?

      If the water from your Rheem Water Heater isn't hot enough, there could be several reasons. The temperature setting might be too low; try increasing it using the remote control. Also, ensure that the gas valve is completely open. If the gas supply pressure is low, contact your gas utility company or a gas contractor to check the gas meter and piping size. Finally, bleed-over in one of the hot water fixtures can also cause this issue; in this case, contact a dealer or a qualified service technician.
