    Why is my Eternity Plus Water Heater water not hot enough?

      If your Eternity Plus Water Heater isn't producing hot enough water, several factors could be at play. You may need to check for cross-plumbing between the cold and hot water lines. Also, ensure the gas supply valve is fully open. The gas line and gas supply pressure should be properly sized and adequate, respectively. Lastly, verify that the set temperature isn't set too low.
