An electric heater consumes on average between 1000 and 2000 watts, depending on the model and the settings used. With an average energy rate of approximately €0.30 to €0.40 per kWh, heating at full power for one hour costs about €0.30 to €0.80. If you set the heater to the lowest setting or use a thermostat, the costs are significantly lower.
How do you calculate the consumption of a heater?
You can calculate the power consumption of a heater with a simple formula: power in watts divided by 1000, multiplied by the number of operating hours and the kWh price. A 2000-watt heater running at full power for an hour therefore consumes 2 kWh. Multiply that by your energy rate and you know exactly what one hour of heating costs. Many heaters, including the Dynter AirFlow HW2002, have adjustable power levels, allowing you to choose between an economical setting and full power. By not running it continuously at the highest setting, you keep costs considerably lower than the theoretical maximum.
What does a heater cost per day and per month?
If you use a 2000-watt heater for three hours a day at full power, you will end up with about 6 kWh per day, or €1.80 to €2.40 at the stated rates. Over a full month, this adds up to somewhere between €54 and €72, just for those few hours a day. If you only use the heater occasionally to quickly warm up a space, the actual costs are often lower because a room does not need to be at full power the entire time to stay warm.
Why do some heaters consume more than others?
The wattage of a heater determines how quickly a room heats up, but also how much power the device draws. A heater with a higher maximum wattage heats a room faster, but is not necessarily more expensive to use if you set it smartly. Models with an adjustable thermostat and multiple settings, such as the HW2002, let you choose exactly how much power is needed for the room you want to heat. This way, you avoid unnecessary use of the highest setting in a small bathroom, while a lower setting is more than sufficient.
How do you keep the power consumption of a heater low?
The biggest savings come from conscious use: only turn on the heater in the room you are in, use a thermostat or timer, and insulate the room slightly by keeping doors closed and windows shut. A heater is primarily intended as auxiliary heating for a single room, such as a bathroom or office, and not for heating an entire house. By using it in a targeted way and on the right setting, you keep both comfort and the energy bill under control.
Direct answer: an electric heater generally consumes 1000 to 2000 watts, which equates to approximately €0.30 to €0.80 per hour at full power. By using the heater on a lower setting or combining it with a thermostat, you can significantly reduce costs.

Frequently asked questions
Is a heater expensive to use?
That depends on the power and how often you use it. At full power, one hour can easily cost €0.60 to €0.80, but at a lower setting or with a thermostat, the costs are considerably lower.
Can I leave a heater on all day?
You can, but it is not necessary and significantly increases energy costs. A heater is most suitable as auxiliary heating for short periods, for example while showering or working in a cold room.
Which is more economical: a heater or central heating?
For heating one small room, a heater is often more cost-effective than turning on the entire central heating system. For heating an entire house, central heating is usually more efficient.
How many watts does a heater for a bathroom need?
For an average bathroom, a power of 1000 to 1500 watts is usually sufficient to quickly reach a comfortably warm temperature.
Is the Dynter HW2002 suitable for daily use?
Yes, the HW2002 is designed for regular use as auxiliary heating and has adjustable power, allowing you to tailor it to the room and the moment.
Does a heater with a thermostat consume less power?
Yes, a thermostat ensures that the heater automatically works less hard as soon as the desired temperature is reached, which reduces consumption in practice.
