Quick Troubleshooting – Find Your Issue

Heater not switching on? Check the mains socket and the main power switch on the back of the heater before pressing the control panel's On/Off button.

Heater blowing cold air? Check whether Cool mode is selected, the Eco thermostat has reached its target temperature or the 15-second cooling cycle is operating.

Heater not producing enough warmth? Select High Heat (HI), check the room size and ensure the air inlet and outlet are clear.

Heater switching on and off? Eco mode automatically stops heating when the selected temperature is reached and periodically runs the fan to circulate air.

Fan continues running after switching off? This is normal. The fan operates for approximately 15 seconds to cool the internal components.

Heater switches off after several hours? Check the countdown timer and separate 24-hour automatic shut-off function.

Heater not oscillating? Check that oscillation is switched on and that nothing is obstructing the heater's movement.

Display appears blank or dim? The display-dimming function may be active. Check the rear power switch and control panel.

Remote control not working? Remove the battery isolation tab, check the CR2025 battery and aim the remote towards the front of the heater.

Display shows E1 or E2? Stop using the heater and contact Morphy Richards Customer Support.

Heater overheating, tripping the electrics or producing a persistent burning smell? Stop using it and follow the relevant safety guidance below.

Before First Use – Where Should I Position My Heater?

Correct positioning is essential for safe operation and effective heating.

1. Remove all packaging from the heater.
2. Place it upright on a firm, flat and level surface.
3. Keep curtains, textiles and other flammable materials at least 1 metre away.
4. Ensure the air inlet and heat outlet are unobstructed.
5. Check that the heater has sufficient space to oscillate without touching nearby objects.
6. Position the mains cable so it cannot be pulled, trapped or tripped over.
7. Connect the heater directly to a suitable earthed mains socket.

The heater is freestanding and does not require wheel or foot assembly.

Important: Never cover the heater, place objects on top of it or use it to dry clothing.

Do not position the heater directly beneath a mains socket or in the immediate surroundings of a bath, shower or swimming pool.

How to Switch On Your HeatFlux Ceramic Tower Fan Heater

The heater has two separate power controls:

• A main Power On/Off switch on the back of the appliance.
• An On/Off button on the control panel and remote control.

Both must be used correctly.

Switching on

1. Ensure the heater is upright and correctly positioned.
2. Plug it into the mains socket.
3. Switch on the main power switch at the back of the heater.
4. The heater will beep and display --, indicating standby mode.
5. Press the On/Off button on the control panel or remote control.
6. The heater will start in High Heat (HI) mode, with the indicator light illuminated red.
7. Press the Mode button to select another operating mode if required.

Switching off

1. Press the On/Off button on the control panel or remote control.
2. The heater will continue blowing cool or room-temperature air for approximately 15 seconds.
3. The display will count down during this cooling cycle.
4. The fan will then stop automatically.

When the heater is no longer required, switch it off at the rear power switch and unplug it from the mains.

Do not interrupt the normal cooling cycle unnecessarily. The short fan run-on helps cool the internal components.

Understanding the Four Operating Modes

Press the Mode button to cycle through:

High Heat (HI) → Low Heat (LO) → Eco Mode → Cool Mode → High Heat (HI)

High Heat (HI)

Provides the heater's highest available heating output.

• The display shows HI.
• The indicator light illuminates red.
• Suitable when you want to warm a cold room more quickly.

Low Heat (LO)

Provides a reduced heating output.

• The display shows LO.
• The indicator light illuminates red.
• Suitable when less heat is required.

Eco Mode

Uses the thermostat to regulate heating according to the selected room temperature.

• Adjustable between 15°C and 35°C.
• Heating stops when the selected temperature is reached.
• The fan periodically operates to circulate air and monitor room conditions.
• Heating resumes when the temperature falls below the selected level.

Cool Mode – Fan Only

Circulates room-temperature air without activating the heating element.

This mode is useful when you want air movement without additional heat.

Important: Cool Mode does not refrigerate or actively lower the room temperature. It circulates the existing room air, like a conventional fan.

How to Set the Temperature in Eco Mode

The adjustable thermostat operates in Eco Mode.

To set your preferred temperature:

1. Switch on the heater.
2. Press the Mode button until Eco Mode is selected.
3. Use the + and – buttons to select a temperature between 15°C and 35°C.
4. The temperature adjusts in 1°C increments.
5. The °C symbol flashes while you adjust the setting.
6. After approximately three seconds without pressing a button, the selected temperature is confirmed.

The heater will regulate its heating according to the selected temperature.

Why does the heater stop blowing warm air in Eco Mode?

This is normal thermostat operation.

When the room reaches the selected temperature, the heater stops producing warm air.

The fan then runs for approximately 30 seconds every five minutes to promote air circulation.

If the room temperature falls below the selected level, the heater resumes blowing warm air.

This intermittent fan operation is normal and does not indicate a fault.

Why does the fan start even though the room is already warm?

If Eco Mode is selected, the fan periodically runs to circulate air even when heating is not required.

The fan may therefore operate without producing warm air.

If the heater is otherwise responding correctly to temperature changes, this is expected behaviour.

Why Is My HeatFlux Heater Blowing Cold Air?

If your heater is blowing cool or room-temperature air instead of warm air, check which operating mode is selected.

There are three common explanations.

1. Cool Mode is selected

Cool Mode operates the fan without activating the heating element.

What to do: Press the Mode button until HI or LO is displayed.

2. Eco Mode has reached the selected temperature

When the room reaches the selected thermostat temperature, heating stops. The fan may continue operating periodically to circulate air.

What to do: If more warmth is required, increase the selected temperature within the 15–35°C range.

3. The heater is completing its cooling cycle

After pressing the On/Off button, the fan continues operating for approximately 15 seconds.

This protects the internal components and is normal.

What to do: Allow the cooling cycle to finish.

What if the heater never produces warm air?

If HI or LO is selected but the heater continues blowing only cold air:

1. Check that the correct heating mode is displayed.
2. Ensure the air inlet and outlet are unobstructed.
3. Check that the heater is upright on a level surface.
4. Check whether it has recently activated its overheat protection.
5. If there are no signs of overheating or damage, switch it off, allow it to cool and restart it.

If the heater continues blowing cold air in both HI and LO modes, contact Customer Support.

Do not attempt to repair the heating element.

Why Isn't My Ceramic Tower Fan Heater Heating Enough?

If the heater produces some warmth but the room does not become as warm as expected, this does not necessarily indicate a fault.

What should I check?

1. Select High Heat (HI). This provides the maximum heating output.
2. Check Eco Mode. If Eco Mode is selected, the heater may stop producing warm air once the selected temperature is reached.
3. Increase the Eco temperature if necessary. Select a temperature above the current room temperature.
4. Check the room size. The heater is recommended for rooms up to approximately 20m².
5. Check the air inlet and outlet. Remove any obstructions that could restrict airflow.
6. Check for heat loss. Open doors, windows, draughts and poor insulation can reduce heating performance.
7. Allow time for the room to warm. Heating performance depends on the starting temperature and room conditions.

Does oscillation make the heater hotter?

No.

Oscillation moves the heater from side to side to distribute warm air across a wider area.

It does not increase the heating element's maximum output.

However, it can help distribute warmth more evenly around the room.

Why doesn't the heater reach the selected temperature?

In Eco Mode, the heater regulates its output based on the temperature it detects.

The temperature near the appliance may differ from the temperature elsewhere in the room.

Large rooms, draughts and poor insulation can also make it harder to reach the selected temperature.

If the heater produces no noticeable warmth in HI or LO mode, follow the troubleshooting guidance for a heater blowing cold air.

Heater Not Switching On or Displaying Power

If your HeatFlux heater will not switch on:

1. Check that the mains plug is securely connected.
2. Test the socket using another electrical appliance.
3. Check the main power switch on the back of the heater is switched on.
4. Confirm that -- appears on the display, indicating standby mode.
5. Press the On/Off button on the control panel.
6. Ensure the heater is standing upright on a firm, flat surface.
7. Check the plug fuse if necessary, replacing it only with one of the same rating as originally fitted.

If the heater remains completely unresponsive, stop using it and contact Customer Support.

Never dismantle the appliance or attempt electrical repairs.

Fan Continues Running After the Heater Is Switched Off

This is normally expected behaviour.

When the heater is switched off using the control panel or remote control, the fan continues blowing room-temperature air for approximately 15 seconds.

During this period:

• The heating element is switched off.
• The fan continues to cool the internal components.
• The display counts down.
• The fan stops automatically when the cycle finishes.

This is a normal safety-related cooling function and does not indicate a fault.

If the fan continues operating well beyond the cooling period, or the heater does not respond to the On/Off button, contact Customer Support.

Heater Switching On and Off During Use

If the heater repeatedly stops producing warm air and then starts again, check whether Eco Mode is selected.

Normal Eco Mode operation

• The heater produces warm air while the room is below the selected temperature.
• Heating stops when the selected temperature is reached.
• The fan runs for approximately 30 seconds every five minutes.
• Heating resumes when the room temperature drops.

Other reasons for switching off

• The countdown timer has finished.
• The separate 24-hour automatic shut-off function has operated.
• The tip-over safety switch has activated.
• The heater has overheated.

If the heater repeatedly stops unexpectedly in HI or LO mode, follow the safety checks below.

How to Use the 24-Hour Countdown Timer

The HeatFlux heater has an adjustable automatic shut-off timer.

This allows you to select a heating period of up to 24 hours.

The timer is a countdown to switch the heater off. It is not a scheduled start function.

How to set the countdown timer

1. Switch on the heater and select your preferred operating mode.
2. Press the Timer button.
3. Use the + or – buttons to select the required time, from 0 to 24 hours.
4. The timer symbol flashes while you adjust the setting.
5. After approximately three seconds without pressing a button, the setting is confirmed.
6. The timer symbol remains illuminated and the countdown begins.

The heater switches off automatically when the countdown finishes.

Why has my heater switched off after a few hours?

If a countdown timer was selected, the heater will switch off when that period ends.

For example, a timer set to four hours will switch the heater off after approximately four hours.

This is normal operation.

How to Use the Separate 24-Hour Automatic Shut-Off Function

The HeatFlux heater also has a separate function that runs the heater for a maximum of 24 hours before switching it off automatically.

This function is different from the adjustable countdown timer.

It can only be activated using the heater's control panel while the appliance is in standby.

How to activate the 24-hour automatic shut-off function

1. Ensure the main power switch on the back is on.
2. Leave the heater in standby mode.
3. Press and hold the Timer button for three seconds.
4. The heater will start operating.
5. The 24hr symbol will illuminate and remain on.
6. The heater will switch off automatically after 24 hours.

How to turn off this function manually

Press and hold the Timer button for three seconds.

Why does the 24-hour function activate again?

The heater has a memory function.

If the 24-hour automatic shut-off function was the last setting used, it may be recalled the next time the heater is operated.

However, switching off the rear power switch, unplugging the heater or activating the tip-over protection resets the appliance to its default settings.

Important: The separate 24-hour function cannot be activated using the remote control.

Can I Programme the Heater to Switch On Automatically?

No.

The HeatFlux heater's timer functions control when it switches off, not when it starts heating at a future time.

The adjustable countdown timer switches the heater off after a selected period.

The separate 24-hour function starts the heater immediately from standby and switches it off after 24 hours.

Neither function allows you to programme a delayed start.

Do not use an external timer, smart plug or separate remote-control switching system to start the heater automatically.

Oscillation Not Working – Heater Not Turning Side to Side

The HeatFlux Ceramic Tower Fan Heater has an oscillating function to distribute air across a wider area.

The heater oscillates through an angle of approximately 80 degrees.

How to turn oscillation on or off

1. Switch on the heater.
2. Press the Oscillate button on the control panel or remote control.
3. The heater will begin moving from side to side.
4. Press the Oscillate button again to stop the movement.

What if the heater doesn't oscillate?

1. Check that the heater is switched on.
2. Press the Oscillate button again.
3. Ensure the heater is standing on a firm, flat and level surface.
4. Remove any objects obstructing the heater's movement.
5. Ensure there is sufficient clearance around the appliance, including approximately 90cm of unobstructed space for oscillation.

Never force the heater to turn manually or attempt to repair the oscillation mechanism.

If the heater produces warmth normally but will not oscillate despite these checks, contact Customer Support.

Display Not Working, Appears Blank or Is Too Dim

The HeatFlux heater has a display-dimming function.

This allows you to turn off the display screen and reduce the indicator light brightness by approximately 50%.

How to dim the display

1. Switch on the heater.
2. Press and hold the Mode button on the heater's control panel for three seconds.
3. The display screen will switch off and the indicator light will dim.

This function can only be operated using the control panel, not the remote control.

How to restore the display

Press and hold the Mode button on the control panel again for three seconds.

What if the display remains blank?

1. Check whether the display-dimming function is active.
2. Check that the rear power switch is on.
3. Check that the mains socket is working.
4. Press the On/Off button to confirm whether the heater responds.

If the heater does not respond and the display remains blank, contact Customer Support.

Why Does My Heater Forget Its Settings?

The HeatFlux heater includes a memory function.

It can remember:

• The last selected operating mode.
• The last selected temperature.
• The 24-hour automatic shut-off function setting.

However, the memory is reset when:

• The heater is unplugged from the mains.
• The main power switch on the back is switched off.
• The tip-over protection is activated.

When this happens, the heater returns to its default settings the next time it is switched on.

This is normal operation and does not indicate a fault.

Remote Control Not Working

The HeatFlux heater includes a remote control powered by one CR2025 3V lithium coin-cell battery.

What should I check?

1. Remove the plastic battery isolation tab. If the remote is new, ensure the protective tab has been removed.
2. Check the battery. Confirm that a CR2025 battery is installed.
3. Check the polarity. Ensure the battery is positioned correctly.
4. Move closer to the heater. The remote may be outside its operating range.
5. Aim towards the front of the heater. Remove any obstructions between the remote and appliance.
6. Replace the battery if necessary. Use a new CR2025 3V battery.
7. Test the heater's control panel. If the heater works normally using its buttons but not the remote, the problem may be isolated to the remote control.

How to replace the remote-control battery

1. Locate the battery compartment at the bottom of the remote.
2. Release the locking latch and slide out the battery holder.
3. Remove the existing battery.
4. Insert a new CR2025 3V battery, observing the correct polarity.
