      Valerie LarsonAug 4, 2025
      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.

      If you're not getting any hot water from your Eternity Plus Water Heater when you open a fixture, consider these potential solutions: * Ensure the unit has a 240V 50Hz power supply. * If using a remote controller, check if it's powered on. * Confirm that both the gas and water supply valves are fully open. * Inspect the cold water inlet filter for cleanliness. * Make sure the hot water fixture is open sufficiently to allow at least 3.0l/min of water flow through the heater. * Check if the unit is frozen or if there's enough LPG in the bottle (for propane systems).
