An electric heater is useful as supplemental heating for a room that just isn't quite warm enough, or for a space you only use occasionally. Which model is best depends primarily on the size of the room and what you are using the device for.
How much power do you need?
As a rough guideline, 60 to 100 watts per square meter is often used for a well-insulated room, and more for a room with a lot of glass or poor insulation. For a room of approximately 15 to 20 square meters, this means a heater of around 2,000 watts usually provides sufficient supplemental heating. Keep in mind that an electric heater is primarily suitable as supplemental heating and not as a complete replacement for your central heating system in a large room.
Which type of heater suits your situation?
A ceramic PTC heater heats up quickly and provides immediately noticeable warmth, which is pleasant in a home office or bathroom where you want quick results. A heater with a fan distributes heat through the room faster, while a model without a fan is often quieter, which is nicer in a bedroom.
Safety features to look out for
Tip-over protection ensures the heater switches off automatically if it tips over, which is important in homes with children or pets. Overheat protection switches the device off before it gets too hot, for example, if the air supply is accidentally blocked. Preferably, always choose a model with both features.
Thermostat and adjustable settings
An adjustable thermostat prevents the room from becoming unnecessarily warm and saves energy, because the heater switches itself off as soon as the desired temperature is reached. Multiple settings give you the freedom to heat up quickly on a cold morning and then switch to a lower, more economical setting.
Where will you use the heater?
- Home office: a compact, fast-heating ceramic heater with a thermostat.
- Bathroom: only a model specifically suitable for damp rooms, at a safe distance from water.
- Bedroom: a quieter model with a timer, so the heater switches off automatically.
