Which Space Heater Should You Choose to Stay Warm This Winter?
A freezing office despite central heating, a garage where tinkering in winter is a real challenge, or a guest room that needs to be heated in a hurry? A space heater is the ideal solution for providing targeted warmth without undertaking major renovations. But faced with a jungle of technologies and models, making the right choice can be difficult.
Follow our guide: we'll break down the essential criteria and present our top picks for your home, workshop, or even your camper van.
The Essential Criteria for Choosing Wisely
To ensure you don't regret your purchase, here are the key points to check. Performance, safety, budget: we scrutinise everything.
1. Technology: Electric, Diesel, or Flame Effect?
The choice of technology is crucial, as it determines the use and efficiency of your device.
- The classic choice: the electric heater. This is the most common category. Among them, the ceramic fan heater stands out for its rapid heat-up time and excellent heat distribution. Compact, it's easy to move around.
- The stylish touch: the electric fireplace. Much more than a simple heater, its main appeal is its decorative aspect. Its LED flame effect creates a cosy atmosphere, ideal for living areas.
- For nomads and pros: the diesel heater. Powerful and self-sufficient, this type of portable heater is indispensable when you're far from an electrical outlet. It's perfect for camper vans, garages, tents, or even construction sites.
2. Power and Consumption: Finding the Right Balance
Power, expressed in watts (W), must be appropriate for the size of the room you want to heat. A simple rule of thumb is to allow about 100W per square metre for a room with a standard ceiling height and decent insulation.
However, a powerful device isn't necessarily an energy guzzler. An energy-efficient space heater can be identified by its precise thermostat and eco-modes, which adjust the power to maintain the temperature without constantly running at full blast.
3. Safety, Noise, and Portability: The Details That Matter
Safety is a non-negotiable criterion. Check for features like overheat protection and a tip-over switch, which automatically shuts off the device if it falls.
For a bedroom or an office, a quiet little heater isn't an option—it's a must. Remember to check the noise level (in decibels, dB). Finally, if you plan to move it from room to room, take a look at its weight, footprint, and whether it has a carrying handle.

Frequently Asked Questions About Space Heaters
1. What power level should I choose for a space heater?
The basic rule is simple: allow about 100W to heat 1 m? in a properly insulated room with a 2.5 m ceiling height. For a 15 m? room, a 1500W device is therefore a good starting point. Of course, this calculation should be adjusted based on the quality of insulation, ceiling height, or the number of windows.
2. What is the most economical space heater to run?
It all depends on your usage! For occasional needs in a well-insulated room, a modern electric heater with a precise thermostat and an eco-mode (like the DREO model) is a very smart choice. However, for a large, poorly insulated space (garage, workshop) or for nomadic use, a diesel heater is often more cost-effective, thanks to its power and the cost of fuel.
3. Can you safely leave a space heater running all night?
Yes, but only if you choose a suitable model and follow basic safety precautions. For overnight use, you must opt for an electric device equipped with comprehensive safety features: a timer, a precise thermostat, overheat protection, and a tip-over switch. On the other hand, combustion appliances (diesel, gas, etc.) are strictly forbidden in a closed, poorly ventilated bedroom. In all cases, caution and carefully reading the manufacturer's instructions remain your best allies for safe and worry-free use.
