Wattage is not the only question: 8 checks before buying an electric space heater

A portable electric heater may seem like a quick answer for a chilly home office or a temporarily underheated flat. The wattage printed on the box, however, does not tell you how well the appliance can be controlled, repaired or positioned safely. This guide is not a product test and does not replace the manufacturer's manual or an on-site electrical inspection.

1. Define the job first

A heater used briefly at a desk has a different task from one intended for a bathroom or a room occupied all day. Check whether the model is a portable or fixed local space heater, which environment it is designed for, and whether the manual permits use in that room. In damp areas, use only equipment explicitly designed and installed for that setting.

2. Convert wattage into electrical load

A 2,000-watt appliance at 230 volts theoretically draws about 8.7 amps. That figure alone does not prove the existing socket, wiring and circuit are suitable, especially when other high-load appliances share the circuit. Stop using the heater and call an electrician if the plug becomes hot, the socket is discoloured, there is a burning smell or protection trips repeatedly.

3. Controls may matter more than peak output

Look for a clear thermostat, several power levels and a timer you will actually use. A thermostat does not make the heater more powerful; it switches the appliance off and on around the set temperature. The display should be readable and the controls understandable even when an app is unavailable.

4. Check repairability, not only the warranty

EU Regulation 2024/1103 has applied to covered local space heaters since 1 July 2025. For electric models placed on the market from that date, manufacturers must make a range of parts available to professional repairers, depending on the model: controls, thermostats, fan motors, circuit boards, sensors, buttons and switches. Availability must continue for at least ten years after the last unit of the model is placed on the market, with delivery within ten working days after an order. Appliances using software must receive free software and firmware updates for at least ten years.

Before buying, find the manufacturer's freely accessible spare-parts list and ordering procedure. If you see only marketing pages with no model identifier, parts prices or service route, ask in writing. These rules do not mean every older heater is automatically repairable, and they do not replace warranty rights.

5. Plug it directly into a wall outlet

Hungarian fire-prevention guidance and the CPSC both advise against running an electric space heater from an extension lead or power strip. Plug it directly into a suitable wall outlet, never route the cord under a rug, and do not pinch it behind furniture. Keep the cable away from the heater's hot airflow.

6. Empty space around the heater is a safety margin

Curtains, bedding, sofas, paper, drying clothes and other combustible items must stay away. The CPSC recommends at least three feet—about 90 centimetres—between a portable heater and combustible materials. The manufacturer may require greater clearance at the front, sides or top; follow the stricter figure. Use a stable, level surface away from walkways.

7. Look for safety functions by name

For a portable model, ask about tip-over shut-off and overheat protection, then check exactly how the manual describes them. A pictogram or marketing name is not a substitute for a functional description. Do not use equipment with a damaged casing, loose switch or unusual noise.

8. Switch it off before sleeping or leaving

Do not leave a portable heater operating unattended, and turn it off before sleep. Allow it to cool before moving or storing it. A heater is not a clothes dryer: covering it can obstruct heat dissipation and start a fire.

Quick buying checklist

• Clearly stated product type and intended use.
• Understandable thermostat, power levels and timer.
• Model identifier, local-language manual and manufacturer contact.
• Public spare-parts list, ordering route and indicative prices.
• Documented tip-over and overheat protection.
• Suitable wall outlet and no extension lead.
• About 90 centimetres of clearance from combustibles, or the manufacturer's greater requirement.
• Regular checks that the smoke alarm works.

Good supplementary heating does not begin with the largest wattage. It begins with a heater that suits the room, the electrical installation and the daily routine—and still has a realistic route to professional repair years later.
