Suitable for larger spaces and whole houses.


  • Initial purchase and installation costs can be relatively high.
  • Performance may decrease in freezing weather.
  • Regular maintenance is necessary for optimal efficiency.

Wood Heaters


  • Offer a cozy and traditional ambience with an open flame.
  • It can be cost-effective, especially if you can access free or cheap firewood.
  • Suitable for off-grid properties.


  • Require a chimney or flue for proper ventilation.
  • Regular cleaning and maintenance are necessary to prevent creosote buildup.
  • Produces particulate matter and emissions, contributing to air pollution.

Oil-filled Heaters


  • Retain heat well and continue to emit warmth even after being turned off.
  • Portable and easy to move around the house.
  • Generally, a safer option as they don’t have exposed heating elements.


  • Slower to heat up compared to other types of heaters.
  • It may not be as energy efficient as other options for long-term use.
  • Not suitable for large spaces or open-plan living areas.

Regular maintenance and following the manufacturer’s guidelines for usage and safety will ensure the most effective and safe operation of electric space heaters and type radiant ceramic heaters.

Key Features of Energy-Efficient Heaters


A. Thermostat and Temperature Control

Look for electric space heaters with adjustable thermostats and temperature control settings. This feature lets you use heat settings to maintain warm air at a desired temperature and prevents unnecessary energy consumption from other space heaters.

B. Energy-Saving Modes

Energy-saving. Infrared heating and heating modes heat settings help optimise space heaters and performance by heating energy and reducing power consumption when infrared radiation in ceramic space heaters in the room reaches the desired temperature range.

C. Programmable Timers

Programmable timers enable your remote control to set specific operating hours and three heating modes for the ceramic electric heater. This way, you can have a ceramic heater with multiple radiant heaters and settings to ensure it runs only when radiant heat is needed, saving energy when the room is unoccupied.

D. Heating Capacity and Area Coverage

Consider the amount of ceramic heating element, the capacity of the portable heater and the area coverage. Choosing a portable heater with a heating element and suitable accommodation for your room size ensures efficient heating of cold space without the heat output overworking the unit.

E. Safety Features

Safety features should always be a priority. Look for tip-over protection, overheating protection, shut-off safety features, and cool-to-touch exteriors to prevent accidents and ensure peace of mind.

Assessing Energy Efficiency

A. Understanding the Energy Efficiency Ratio (EER)

The Energy Efficiency Ratio (EER) is a crucial metric when evaluating the energy efficiency of an infrared small space heater or electric floor space heater. This ratio quantifies the heat output generated by the infrared heater relative to the energy input it consumes.

In simpler terms, the EER indicates how effectively the infrared heater converts energy into heat. The higher the EER value, the more efficient the infrared small space heater is, meaning it can produce more heat with less energy consumption. When comparing different models of small space heaters, paying attention to their respective EER values can help you decide on the most energy-efficient option that suits your needs and budget.

B. Checking the Heater’s Energy Label

To gain insights into a small space heater’s energy efficiency and consumption, locating and carefully examining its energy label is essential. The electric or space heater’s packaging or product information usually contains this label. The energy label provides valuable data and information, such as the next best space heater made’s energy efficiency rating, annual energy consumption, and other relevant details.

Manufacturers typically use standardised energy efficiency ratings and labels to help consumers compare different models easily. By checking and comparing these labels, you can identify the most energy-efficient options and make a well-informed choice that aligns with your energy-saving goals.

C. Reading Online Reviews and Expert Recommendations

Let’s talk about finding the most energy-efficient small space heaters! It’s essential to do some research to make the right choice. One great way to start is by checking out online customer reviews. These real-world experiences can give you valuable insights into specific heaters’ performance and efficiency. Look for reviews about energy efficiency, heating capabilities, and any cool features that can save you energy.

But that’s not all! Remember to seek advice from experts in the heating industry. You can check out reputable sources that conduct product testing and evaluations. Expert recommendations can help you narrow your options and find the best space heaters that have impressed the pros.

Combining customer reviews and expert opinions gives you a complete picture of the different heaters’ energy efficiency. That way, you can choose the perfect heater for your space, saving energy and money! So, get researching and stay cozy!

Tips for Maximising Energy Savings

  1. Optimal thermostat settings: Set your thermostat to the lowest comfortable temperature during winter. Lowering the temperature by just a few degrees can result in significant energy savings over time.
  2. Programmable thermostat: Invest in a programmable thermostat that allows you to schedule heating periods based on your daily routine. This way, you can avoid heating an empty house and save on unnecessary energy consumption.
  3. Zone heating: If you have multiple rooms in your home, consider using space heaters or portable heaters in specific areas instead of heating the entire house. This technique, known as zone heating, allows you to target warmth where it’s needed most.
  4. Proper heater placement: Place your heater strategically for optimal heat distribution. Avoid placing furniture or obstacles in front of the heater, as this can block the airflow to the radiant heater and reduce its efficiency.
  5. Seal drafts and insulate: Ensure your home is well-insulated and seal any drafts around windows and doors. Proper insulation prevents heat loss and reduces the workload on your heater.
  6. Use sunlight: During sunny days, open curtains or blinds to let natural sunlight warm up your rooms. This passive heating method can supplement your heater and save energy.
  7. Layer up: Dress warmly indoors during colder months and use cozy blankets to stay comfortable. By relying less on your heater, you can reduce energy consumption.
  8. Regular maintenance: Keep your heater well-maintained by cleaning and inspecting the filters. A well-maintained heater operates more efficiently, ensuring maximum energy savings.
  9. Use ceiling fans wisely: If your heater has a ceiling fan mode, use it to circulate warm and cold air throughout the room. It helps to distribute heat evenly and allows you to set the heater at a lower temperature.
  10. Unplug unused heaters: If you have multiple heaters in your home, unplug the ones you’re not using. It prevents any standby power consumption and saves energy.
  11. Consider Energy Star certified heaters: When buying a new heater, look for models with the Energy Star label. These heaters meet strict energy efficiency standards and can save you money in the long run.
  12. Use curtains and rugs: In the evenings, close curtains and use rugs on hardwood or tile floors to prevent heat from escaping and maintain a warmer indoor environment.
  13. Combine heating methods: If you have a central heating system, consider using it with energy-efficient portable small space heaters or heaters. This way, you can lower the temperature of your central heating while providing additional warmth to specific areas with electric space heaters or heaters.
