    Why is my EemaX FlowCo SPEX48 producing low heat?
    • N
      Nancy MendezAug 20, 2025
      Low heat from your EemaX Water Heater can occur for several reasons: - The outlet temperature is below 90°F/32°C for 5 seconds of flow. - Element failure. - ECO tripped or malfunctioning. - Relay/contactor malfunctioning. - Control board failure. - Inlet water supply out of spec. To attempt a fix, reduce the flow through the unit.
