It is preferable to connect an electric heater directly to a wall socket. If an extension cord is unavoidable, use only a cord suitable for high power, unroll it completely, and do not use a power strip with multiple devices. After all, a 2000-watt heater draws a lot of power, and a cord that is too thin or remains coiled can overheat.
Direct answer: yes, it is possible, but only with an extension cord designed for this power level, fully unrolled, and with nothing else connected to it. The safest option is to have a wall socket within reach of the heater. Always follow your heater's manual.
Why is a heater so demanding on a power cord?
An electric heater uses almost all its power to generate heat and therefore draws a lot of power continuously. At the 230 volts commonly used in the Netherlands, a 2000-watt heater draws approximately 8.7 amperes (2000 divided by 230). That is considerably more than a lamp or phone charger. As a result, an extension cord with thin wires can overheat, and this risk increases if the cord is still on the reel or lies under a rug.
What to look for in an extension cord for a heater?
First, check the cord itself or the packaging for the maximum power rating. It must be at least equal to the power of your heater, preferably higher. Always unroll a cable reel completely, even if you only need a short length. Do not use the cord for other heavy-duty appliances at the same time, and do not place it under a rug, behind furniture, or in a place where it will be stepped on. After an hour of use, check whether the plug and cord are excessively hot; if they are, unplug the device and choose a different solution.
| Situation | Advice |
|---|---|
| Heater connected directly to a wall socket | Best and safest option |
| Extension cord suitable for high power, fully unrolled | Possible, keep the cord short and within sight |
| Coiled cable reel | Do not use, as the cord can overheat |
| Power strip with multiple devices | Do not use, as the total load is too high |
What does the Dynter HW2002 say about this?
Dynter AirFlow HW2002: an electric heater with adjustable power from 1500 to 2000 watts, suitable for rooms up to 40 m². The temperature can be set from 15 to 45 °C.
Cable length: 1.7 meters, so that you can often place the heater without an extension cord if you have a wall socket nearby. Therefore, it is better to place the heater near a wall socket than to use an extension cord.
Safety: overheat protection and fall detection, after which the heater automatically switches off. This is an extra safety feature, but it does not replace a proper connection. Read more about what fall detection and overheat protection in a heater are.
Operation: LCD touchscreen, remote control, timer function, and a rotating function for even heat distribution.
The product page does not mention using an extension cord. Therefore, consult the included manual and, if in doubt, choose a direct connection.
How to place a heater safely
Place the heater on a flat, stable surface with sufficient distance from curtains, furniture, and clothing. Read more placement tips in how to safely place an electric heater. Do not leave a heater unattended; whether it can be left on overnight is explained in can an electric heater be left on all night. Want to know how much it costs to run?

Frequently asked questions
Can an electric heater be plugged into a power strip?
We advise against it. A power strip distributes electricity to multiple devices, which can quickly make the load too high. It is better to connect a heater directly to a wall socket.
Which extension cord is suitable for a 2000-watt heater?
Choose a cord that is expressly suitable for this power level or higher. The maximum power is stated on the cord or the packaging. If in doubt, ask in the store or choose a shorter cord with thicker wires.
Can an extension cord get hot?
Yes, especially if the cord is too thin, still on the reel, or lying under something. If the cord or plug feels very hot, unplug the device immediately.
Why does the HW2002 have a short cable?
The cable is 1.7 meters long. This is intended to allow you to place the heater flexibly, but without having to run a long cord through the room, which is also a risk.
Which is more energy-efficient: the heater on low or high setting?
The low setting (1500 W) uses less electricity per hour than the high setting (2000 W). For a small room, the low setting is often sufficient.
