Water heater occasionally shuts down when multiple taps are opened at once.

Safety: This is usually a performance issue, not a safety fault, but monitor for any error codes.

• Limit simultaneous use: Avoid running multiple showers and taps at the same time beyond the heater's rated flow.
• Check supply pressure: Ensure water and gas pressures remain within Termet specifications under load.
• Service burner and sensors: Have a technician clean the burner, check gas pressure, and verify flow sensor operation to maximize capacity.
