What types of space heaters are available?
There are many types of space heaters to choose from, each with its own advantages and disadvantages. Here’s an overview.
Convector heaters for even warmth
Convector heaters warm the air in a room directly. They draw in cool air, heat it and release it back into the room, creating an even temperature. A good example is the convector heater with timer (). The timer adds convenience and can help save energy.
These heaters are especially suitable for rooms that need heat for extended periods, such as living rooms or bedrooms. They run quietly and often have a slim design.
Plug-in heaters for targeted warmth
Plug-in heaters are compact and portable. Just plug one into an outlet for quick heat. Modern models such as the plug-in space heater with remote control () let you adjust the heat from across the room.
These heaters are great for a home office or bathroom, or as a source of supplemental heat. Make sure the heater has enough power for the size of your room.
Radiator accessories for greater efficiency
Not every heating solution is a standalone appliance. Accessories can help optimize your existing heating system. Self-adhesive radiator reflector foil () reflects heat back into the room, reducing energy loss.
The radiator bleed key – save on heating costs quickly and easily () releases trapped air from the system. This improves circulation and can help lower your heating costs. Find more options in our space heaters category.
Tip: Pair an efficient primary heater with accessories that improve performance. This can boost overall efficiency and help you save money over time.
How we test space heaters
Our testing process is practical and transparent. We evaluate each heater using a consistent set of criteria.
Practical testing under real-world conditions
We use the space heaters in different rooms, measuring how quickly they warm up and how evenly they distribute heat. Each heater should reliably deliver its stated performance.
Ease of use matters in everyday life. Is the heater easy to move? Are the controls intuitive? We answer these questions for you.
Assessing safety and energy consumption
Safety features such as overheat and tip-over protection are essential. We check that each heater provides them reliably. We also compare energy consumption with the heat produced.
An energy-efficient heater is of little use if it doesn’t provide enough heat. Our testing helps identify the right balance.

Top picks for different needs
For steady room heating, the Convector heater with timer () is an excellent choice. Its programmable controls and even heat distribution make it a versatile option.
For quick, targeted warmth, the plug-in heater with remote control () is ideal. The remote control makes it especially convenient. The Halogen heater, 3 settings () delivers direct radiant heat, making it a good choice for a patio or workshop.
Buying guide: What to look for
The right heater depends on your needs. Keep these factors in mind.
Consider how you'll use it and the room size
First, think about where and how long the heater will run. Your living room needs a different solution than a guest room you rarely use. Measure the room in square meters.
The heater's output should match the room size. An undersized heater will run continuously at full power, which can be inefficient and expensive. Follow the manufacturer's recommendations.
Features for comfort and control
Modern features can make a heater much more convenient. A thermostat maintains your preferred temperature automatically. A timer turns the heater on and off when you want.
A remote control or smart app gives you added flexibility. Consider which features will be useful in your daily routine. Find more technology tips under Technology.
Note: Heat output is measured in watts. As a guideline, allow around 80-100 watts per square meter with standard insulation. High ceilings or poor insulation may require more power.
Installation and safety
Safe setup and operation are essential. Follow these basic rules.
Position your heater safely and connect it properly
Always place a space heater on a firm, level surface. Keep it a safe distance from flammable materials such as curtains and furniture—at least one meter.
Plug plug-in heaters directly into a wall outlet. Don't use extension cords or power strips, which can overload and start a fire.
Maintenance and regular checks
Before each heating season, check the heater for visible damage. Clean dust from the air vents regularly to maintain proper airflow and help prevent overheating.
For fan heaters, follow the manufacturer's maintenance instructions. Accessories such as air vents () need little maintenance and can help improve your heating system's performance over time.
Energy efficiency and saving money
An efficient heater is better for the environment and your wallet. Here's how to heat your home more economically.
Optimize your existing heating system
You may not need a new heater. Simple improvements can make your central heating system more efficient. Radiator reflector foil () is quick to install and starts working right away.
Bleed your radiators regularly using a radiator air vent such as or
. This can improve performance and lower energy costs. A well-maintained heating system runs more efficiently.
Use smart controls
Heat only the rooms you use, and only when you need warmth. Use the timer and thermostat. Close the doors to rooms you use less often.
Lower the temperature by a few degrees at night or when you're away. Modern heaters such as can do this automatically. These small changes can add up to significant savings.
Conclusion
Our 2026 space heater review and comparison shows that the right heating solution balances your needs, energy efficiency, and safety. For everyday room heating, programmable convector heaters such as are an excellent choice.
