Energy Safe Victoria has advised that abnormally low gas pressure can cause issues with Rheem 5-Star gas storage water heaters

Energy Safe Victoria has been advised by Rheem of an issue that may arise when their 5-Star gas storage water heaters (as listed below*) are operated with abnormally low gas supply pressures.

When gas supply pressure drops to around 0.2 kPa (vs. normal supply pressure of at least 1.13 kPa) then, over a very narrow pressure band, there is a risk of unreliable cross-ignition from the pilot to the main burner. This can result in delayed ignition, with consequent damage to the heater.

The relevant water heaters are:

  • Rheem Stellar 330, model # 850330N0

  • Rheem Stellar 360, model # 850360N0

  • Rheem 5 Star 265, model # 350265N0

  • Rheem 5 Star 295, model # 350295N0

  • RheemPlus 5 Star 265, model # 354265N0

  • RheemPlus 5 Star 295, model # 354295N0

  • Everhot 5 Star 265, model # 250265N0

  • Everhot 5 Star 295, model # 250295N0.


This issue is not related to any lapse in product or manufacturing quality.  It may become evident only in situations where supply pressure falls well below normal levels.
