Why is my electric heater blowing cold air?

If your QCen ECO Low Consumption Electric Heater is blowing cold air instead of warm air, even though it's turned on, the issue might be airflow obstruction. Check the air inlet and outlet vents for any blockages. Common culprits include curtains, plastic bags, or paper that may have been drawn into the unit. Ensure these items are clear of the heater. Once cleared, turn off the heater and let it cool down completely before turning it back on. This should restore the heater's ability to produce heat efficiently.
