Style and Installation
Style-wise, the FLAMME presents a white, 3-sided electric fireplace look as a freestanding unit, so it can be placed in front of a wall rather than fitted into it. That makes it suitable for rooms where people want to avoid building work. Setup is largely straightforward because the unit can be positioned wherever a nearby power point allows. A slim, clean frame keeps the visual profile light, while the 43in width (110cm) provides a clear focal area. The white finish suits many interiors, but it can show dust more easily.
Heat Output and Room Size
Because the electric fireplace is rated at 1500W, it can deliver noticeable warmth in many everyday rooms. Real-world comfort still depends on insulation quality and air movement in the space. The 43in-wide unit is suited to living rooms or open-plan areas, but how evenly heat spreads is determined by room size and layout. In a smaller, well-sealed room it may feel more effective at lower levels, while larger or more draughty areas may require longer operation. For best results, position it so it faces into the room, without being blocked by furniture or curtains.
Flame Effect and Realism
How convincing is the flame effect on the FLAMME/43 inch electric fireplace? The design uses multiple flame colours to create visual variety, which stands out quickly during viewing. The 3-sided display helps the flame visuals wrap across more surfaces, improving the effect compared with models that read as a single flat line. Realism is still influenced by room lighting, because bright ambient light can reduce contrast and make the flame edges appear more sharply defined than natural fire. The crackling sound effect supports the overall illusion, but it does not fully replicate the movement and natural dynamics of real flames.
Controls and Features
Controls and features on the electric fireplace/43" three-sided electric free standing fireplace are designed to adjust the ambience without reaching the unit. The flame display supports multiple flame colours, alongside a 1500W heater and a crackling sound effect. Convenience options include both remote control and app control, allowing settings to be changed from elsewhere in the room. App operation requires the same adjustments to be selected and then confirmed, since delays or connectivity issues, if they occur, could slow response. The controls are kept external to the unit, but manual operation may still be needed if power is interrupted.
Who Is This For?
Selecting the FLAMME Knighton 110cm/43" 3-sided electric free-standing fireplace makes the most sense for people who want a room-filling flame effect without installing a wall or building a hearth. It suits buyers who value placement flexibility, because it is free-standing and 43 inches wide, so it can be moved between rooms as needs change. The 1500W heater fits those looking for a straightforward electric heat source rather than a replacement for central heating. Remote and app control are useful for quick adjustments from a distance. A crackling sound adds a more immersive ambience, but it may also distract in quieter rooms.
Where to Buy in the UK
In the UK, the FLAMME/43" 3-sided electric free standing fireplace can typically be found through major online home and electrical retailers, and it may also appear on smaller furniture, home décor, or fireplace-focused websites. When comparing listings, shoppers should confirm that the product matches the stated 110cm/43" size and that it is electric, freestanding, and 3-sided.

Frequently Asked Questions
Is the electric fireplace worth it?
As a room feature with supplementary heat, the FLAMME (freestanding fire) does the job, with 1500W of heat. Electric fires are chosen mainly for the look and the instant, flue-free warmth. Check the current Amazon UK price, as fireplaces are discounted heavily outside the autumn peak.
How is the electric fireplace installed?
This electric fireplace is a freestanding fire. Wall-mounted fires hang on the wall using the supplied bracket - check the wall type and use appropriate fixings, especially on plasterboard - and need a socket or a spur within reach.
How much heat does the FLAMME give out?
The FLAMME Knighton 110cm is rated at 1500W. Most electric fires top out around 2kW, which realistically takes the chill off a small to medium room rather than heating a large or poorly insulated space. Treat it as supplementary heating and a focal point rather than a replacement for central heating. The lower setting is usually the more economical everyday choice.
What size is the electric fireplace?
This electric fireplace measures 43in wide. For inset and media wall fires, the width is the headline figure but the required recess DEPTH is what most often catches people out - always check it against your wall build-up before ordering. For freestanding and wall-mounted models, check the width suits the wall or alcove you have in mind.
How realistic is the flame on the FLAMME?
The electric fireplace uses crackling sound. Flame realism is largely why people choose one electric fire over another, so it's worth looking at video of it running.
What features does the FLAMME have?
The electric fireplace offers remote control, app / smart control. A remote is genuinely useful on an inset or wall-mounted fire you can't easily reach. Match the features to how you'll actually use it.
Are electric fireplaces expensive to run?
Running cost depends on the heat setting and your electricity tariff. At full output most electric fires draw around 2kW, so an hour at full heat costs roughly the same as running any 2kW heater - use the lower setting or a thermostat to cut that considerably. Crucially, the flame effect alone uses very little (it's just LEDs), so leaving the flames on without heat costs pennies.
