There’s something timeless about the comfort of a fire; the soft glow, the steady warmth, the way it draws you in on cold evenings. But modern homes are shifting away from traditional fireplaces, trading wood and gas for smarter, more efficient alternatives. Electric fires have come a long way, shedding their dated, artificial look for sleek designs and convincing flame effects that don’t drain energy or budgets. In this guide, we’re looking at the best energy-efficient electric fires available in the UK, balancing style, running costs, and performance to help you find one that actually feels right for your home.

How energy efficient are electric fireplaces?
Electric fireplaces are known for their high energy efficiency because they convert almost all the electricity they use into heat. There’s no heat lost through a chimney or vent, unlike with gas or wood-burning fires. This means that if an electric fire is rated at 2kW, nearly all of that energy contributes to heating the room.
The efficiency also comes from the fact that you can heat only the room you’re using often called “zone heating” rather than turning on the central heating for the whole home. Many modern models feature thermostats and timers to help control energy use even further.
Can an electric fireplace heat a large room?
Yes, but the capacity depends on the fire’s wattage. A typical 2kW electric fire can comfortably heat a medium-sized room, roughly up to 20 square metres. For larger areas, you may want to use it as a supplementary heater alongside your central system.
How can I get the best heating results from my electric fire?
-
Choose the right size for your room: Check the fire’s heat output (usually measured in kilowatts). A 1–2 kW model suits small to medium-sized rooms, while larger or open-plan areas might benefit from infrared or higher-capacity units.
-
Position wisely: Place the fire in a central spot where airflow isn’t blocked by furniture or curtains. Avoid corners where heat may not circulate properly.
-
Use zone heating: Turn down the central heating and warm only the room you’re using. Electric fires provide targeted comfort without wasting energy on empty spaces.
-
Keep vents clean: Dust build-up can restrict airflow and reduce efficiency. A quick vacuum around the air intake and outlet will help maintain even heating.
-
Use timers and thermostats: Many models come with programmable settings. Set the fire to run only when needed, maintaining comfort while saving on energy bills.
-
Close doors and windows: Prevent heat loss by keeping the space sealed when the fire is running. Draught-proofing makes a noticeable difference in maintaining warmth.
-
Combine with soft furnishings: Rugs and curtains help trap heat and reduce draughts, complementing the warmth of your electric fire.
