How many square meters an electric heater can heat depends mainly on its power, the insulation, and the ceiling height. A 2000-watt heater is intended for a medium-sized room; manufacturers specify a maximum area. That figure is a guideline, not a guarantee for every home.
What does the range of a heater depend on?
The power in watts tells you how much heat the device can output per hour, not how large the room can be. Whether that heat is sufficient depends on the room itself. A well-insulated living room with double glazing retains heat, while a drafty room with single glazing or a high ceiling loses much more heat. The same heater will therefore feel very different in these two rooms.
The difference between the outside temperature and the desired room temperature also plays a role. On a winter day, you lose more heat than in autumn. Open connections to other spaces, such as an open staircase or kitchen, also increase the volume you need to heat.
What does the manufacturer say about the area?
Dynter states that the HW2002 is suitable for spaces up to 40 m², with an adjustable power output of 1500 to 2000 watts. Consider this an upper limit under favorable conditions. If you have a room that is close to that limit, it is wise to allow for a longer warm-up time and to run the device at the higher power setting.

Which power output is suitable for which room?
The table below is our own rough rule of thumb based on the product range and is intended as a guide. It is an assumption, not a measured result.
| Situation | Guideline | Tip |
|---|---|---|
| Small room, well insulated | Low power (1500 W) is often sufficient | Set a temperature and let the device adjust |
| Average living room | Medium to high power | Close doors and curtains to retain heat |
| Large or drafty space | High power (2000 W), longer warm-up time | Consider the heater as supplementary heating, not as the main heat source |
How much does it cost to heat a room?
A 2000-watt heater uses 2 kWh per hour at continuous full load. Assuming a rate of 0.30 euros per kWh, that is 0.60 euros per hour. Your rate may vary, so check your own contract. In practice, a device with a thermostat will regularly switch off as soon as the room is warm, resulting in lower actual consumption. You can find the full calculation in how much an electric heater costs per hour.
Heating smartly with a heater
Only heat the room where you are sitting and keep the door closed. Do not place the heater behind a sofa or curtain, and never use it with an extension cord if this is not permitted by the manual. Use the timer so that the device does not continue to run unnecessarily. Do you want a heater in the bedroom? Then first read can you use an electric heater in the bedroom.

Are you looking for a heater for a specific room? Check out the HW2002 or the entire heater collection.
Direct answer: a heater heats a room up to the maximum area specified by the manufacturer, up to 40 m² for the HW2002. Insulation, ceiling height, and drafts determine whether this is achievable in your home.
Frequently asked questions
Can one heater heat an entire home?
Usually not. A heater is intended as supplementary heating for one room. For an entire home, a central system is more practical.
Is 2000 watts always necessary?
No. In a small, well-insulated room, a lower power output is often sufficient. Adjustable power gives you the flexibility to choose.
What is the difference between power and range?
Power is the amount of heat the device provides. Range is the size of the room for which the manufacturer considers it suitable.
Is a heater safe to leave on?
Use it according to the manual, on a stable surface, and away from curtains. The HW2002 has overheat protection and fall detection.
Does a heater make the air drier?
Heating reduces relative humidity, even if no moisture is lost. Read more in does an electric heater make the air drier.
