- Secure the feet using the supplied screws, tightening them firmly.
- Return the heater to its normal upright position.
- Check that both feet are secure and the heater stands firmly without rocking.
Important: Always operate the heater upright with both feet correctly fitted. Never operate it on its side, without its feet or on an unstable surface.
Where should I position my convector heater?
Place the heater on a firm, flat, stable and heat-resistant floor.
- Keep curtains, textiles and other flammable materials at least 1 metre away.
- Ensure the air inlet at the bottom and air outlet at the top remain unobstructed.
- Do not place objects on top of the heater.
- Do not position the heater directly below a mains socket.
- Keep the power cable fully unwound and away from hot surfaces.
- Do not position the heater where it could be knocked over.
Plug the heater directly into a suitable earthed mains socket.
Never cover the heater or use it to dry clothing.
How to Switch On and Use Your HeatFlux Convector Heater
Once the heater is correctly assembled and positioned:
- Plug the appliance into a suitable mains socket.
- The heater will enter standby mode and display --.
- Press the Power On/Off button on the control panel.
- The heater starts with a default temperature setting of 23°C.
- Press the Mode button to select Low or High heat mode.
- Use the Temperature Increase button to adjust the thermostat to your preferred temperature.
When a temperature is selected, the display flashes for approximately three seconds before returning to the surrounding room temperature.
The heater will then regulate its heating according to the selected settings.
How do I switch the heater off?
Press the Power On/Off button to switch off the heater.
When it is no longer required, unplug it from the mains supply.
Allow the heater to cool completely before moving, cleaning or storing it.
Understanding the Two Heating Modes
The HeatFlux Convector Heater has two heating modes:
Low Mode
Provides a reduced heating output, suitable when less warmth is required.
High Mode
Provides the heater's maximum available heating output, suitable when you want to warm the room more quickly.
Press the Mode button to switch between Low and High.
The corresponding heat mode symbol illuminates on the display.
Which heat mode should I use?
Choose High Mode when the room is particularly cold or you want it to warm more quickly.
Choose Low Mode when less heating is required or you want to maintain a comfortable temperature using a reduced power setting.
Both modes work with the adjustable thermostat.
Important: Selecting High Mode does not mean the heater will run continuously. The thermostat can still switch the heating on and off to maintain the selected temperature.
How to Set the Thermostat Temperature
The HeatFlux Convector Heater has an adjustable thermostat with a temperature range of 10°C to 35°C.
To adjust the temperature:
- Switch on the heater.
- Select Low or High Mode.
- Press the Temperature Increase button on the control panel to adjust the selected temperature.
- The display will flash for approximately three seconds to confirm the setting.
- The display will then return to showing the surrounding room temperature.
You can also adjust the temperature using the + and – buttons on the remote control.
Why does my heater stop heating when the room reaches the selected temperature?
The thermostat automatically regulates heating.
When the room reaches the selected temperature, the heating may switch off. It resumes when the temperature falls sufficiently below the selected level.
This is normal operation and helps maintain a comfortable room temperature without heating continuously.
Understanding the Temperature Display
A common source of confusion is the difference between the selected thermostat temperature and the room temperature shown on the display.
When you change the thermostat setting, the selected temperature briefly flashes on the display.
After approximately three seconds, the display returns to showing the surrounding room temperature.
For example, if you select 25°C but the room is currently 18°C, the display may return to 18°C after confirming the setting.
As the room warms, the displayed temperature should gradually increase.
This does not mean the thermostat has reset or that the heater has failed to save your selected temperature.
The temperature detected near the heater may also differ from the temperature elsewhere in the room.
Why Isn't My Convector Heater Heating Enough?
If your HeatFlux heater isn't producing enough warmth or is taking longer than expected to heat the room, this does not necessarily indicate a fault.
Convector heaters work by warming the surrounding air. Cooler air enters through the lower inlet, is heated inside the appliance and rises through the upper outlet.
This creates natural air circulation around the room.
Unlike a fan heater, this model does not use a fan to blow hot air directly towards you.
What should I check?
- Select High Mode. This provides the maximum available heating output.
- Increase the thermostat temperature. Ensure the selected temperature is above the current room temperature.
- Allow time for the room to warm. Heating performance depends on the room's starting temperature, size and insulation.
- Check the air inlet and outlet. Ensure neither opening is covered or obstructed.
- Check the heater's position. Make sure there is sufficient space around the appliance for air to circulate.
- Check for heat loss. Open doors, windows and draughts can reduce heating performance.
- Check the countdown timer. Ensure the heater has not reached the end of a previously selected heating period.
Should I feel hot air blowing from the heater?
No. This model uses natural convection rather than a fan.
Warm air rises from the heater's upper outlet as cooler room air enters through the lower inlet.
You may not feel a strong stream of air, even when the heater is operating correctly.
Never place your hands inside the air outlet or touch hot surfaces to test whether the heater is working.
Is a 2kW convector heater suitable for a large room?
The HeatFlux 2kW Convector Heater is designed for rooms up to approximately 20m².
However, heating performance varies depending on:
- Room size and ceiling height.
- Insulation and window glazing.
- Outside temperature.
- Draughts and heat loss.
- Selected heating mode and thermostat temperature.
A larger or poorly insulated room may take longer to warm or may not reach the desired temperature.
If the heater produces noticeable warmth but struggles to heat a large space, this does not automatically indicate a fault.
Heater Not Switching On
If your HeatFlux heater does not power on or the display remains blank:
- Check that the mains plug is securely connected.
- Test the socket using another electrical appliance.
- Check whether the heater displays -- when connected to the mains.
- Press the Power On/Off button.
- Check that the heater is upright and standing securely on both feet.
- If the plug fuse needs replacing, use a fuse of the same rating as originally fitted.
If the heater remains completely unresponsive, stop using it and contact Morphy Richards Customer Support.
Never attempt to dismantle or repair the electrical components yourself.
Why Does My Heater Keep Switching On and Off?
If the heater warms the room, stops heating and then starts again, this is usually normal thermostat operation.
The heater automatically regulates its heating output to maintain the selected temperature.
Normal operation
- The heater produces warmth while the room is below the selected temperature.
- Heating stops when the thermostat determines that sufficient warmth has been reached.
- Heating resumes when required.
- The display continues to show the surrounding room temperature.
When might there be a problem?
Further investigation may be needed if:
- The heater repeatedly shuts down shortly after starting despite the room being cold.
- The display switches off unexpectedly.
- The heater stops producing heat regardless of the selected temperature.
- The overheat protection repeatedly activates.
- The heater produces a burning smell or shows signs of damage.
If the heater repeatedly switches off unexpectedly, follow the checks in Heater Cutting Out or Switching Off Unexpectedly.
How to Use the 24-Hour Countdown Timer
The HeatFlux Convector Heater includes a countdown timer that can be set for up to 24 hours.
The timer allows you to select how long the heater operates before automatically switching off.
Important: This model has a countdown shut-off timer. It cannot be programmed to switch on automatically at a later time.
How to set the timer using the heater's control panel
- Switch on the heater and select your preferred heating settings.
- Press the Timer/Child Lock button.
- The display will flash 00.
- Continue pressing the Timer/Child Lock button until your preferred countdown time is displayed.
- Wait approximately three seconds for the setting to be confirmed.
- The display will return to showing the surrounding room temperature.
The heater will automatically switch off when the selected countdown period has elapsed.
How to set the timer using the remote control
- Switch on the heater.
- Press the Timer button on the remote control.
- Use the + and – buttons to select your preferred countdown period, up to 24 hours.
- Wait approximately three seconds for the setting to be confirmed.
- The timer symbol will illuminate on the heater's display.
Why has my heater switched off after a few hours?
If a countdown timer was selected, the heater automatically switches off when the set period ends.
For example, selecting a four-hour timer means the heater will switch off after approximately four hours.
This is normal operation.
If the heater switches off earlier than expected, check the selected timer and the thermostat before investigating a possible safety cut-out.
Can I set the heater to switch on before I get home?
No.
The timer is designed to switch the heater off after a selected period, not to start it automatically.
Do not use an external timer, smart plug or separate remote-control switching system to operate the heater automatically.
Child Lock – Why Aren't My Controls Responding?
The HeatFlux Convector Heater includes a child lock to prevent accidental changes to the settings.
How to activate the child lock
- Switch on the heater.
- Press and hold the Timer/Child Lock button for three seconds.
- The child lock symbol will illuminate on the display.
When the child lock is active, the Power On/Off button is the only control that remains operational.
How to deactivate the child lock
- Press and hold the Timer/Child Lock button for three seconds.
- The child lock symbol will disappear.
- The other controls will become available again.
If the buttons appear unresponsive, check whether the child lock symbol is illuminated before assuming there is a fault.
Remote Control Not Working
The HeatFlux Convector Heater includes a remote control powered by one CR2025 3V lithium coin-cell battery.
What should I check?
- Check the battery. Ensure a CR2025 battery is fitted correctly.
- Check the polarity. The positive and negative sides must match the markings in the battery compartment.
- Move closer to the heater. The remote may not work if it is too far away.
- Aim towards the heater's control panel. Ensure there are no obstructions.
- Replace the battery if necessary. Use a new CR2025 3V battery.
- Test the heater's touch controls. If the heater works from its control panel but not from the remote, the problem may be isolated to the remote control.
How to replace the remote-control battery
- Open the battery compartment at the bottom of the remote control.
- Remove the existing battery.
- Insert a new CR2025 3V battery, ensuring the polarity is correct.
- Securely refit the battery cover.
