    Why is my EemaX FlowCo SPEX4277 Water Heater producing low heat?
    • S
      shendrixAug 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.

      Matthew CortezAug 22, 2025
      If the flow in your EemaX Water Heater is too high, preventing the water from heating to the setpoint temperature, reduce the flow. You can achieve this by using an outlet flow restrictor or a faucet aerator.
