Heater emits a rotten egg (sulfur) smell from hot water.

Safety: Odor is unpleasant but typically not acutely toxic. Ventilate the area if smell is strong.

Steps:

• Disinfect tank: Turn off power, drain the tank, and refill with a diluted disinfectant solution (e.g., chlorine-based) following local guidelines. Let it sit, then flush thoroughly.
• Consider anode change: Replace the magnesium anode with an aluminum-zinc anode if compatible with your Eldom model to reduce odor.
• Raise temperature periodically: Periodically heating water to 60°C (if safe for your system) can reduce bacterial growth.
• Water treatment: If the problem persists, consult a water treatment specialist about sulfate reduction.
