The Dimplex 2kW Atlantic Mantle Electric Fireplace is a freestanding electric fire designed to add both visual warmth and practical spot heating to living areas and bedrooms. It suits renters, apartment dwellers and households wanting an easy fireplace look without flues or fuel. Key strengths are its classic mantle styling, simple operation and low-fuss setup.

Apartment suitability
High - well suited to apartments and rentals where a traditional fireplace is not practical
Ambience creation score
8/10 - classic mantle styling and flame effect create a strong focal point in living spaces
Heating effectiveness
7/10 - up to 2kW is effective for small to medium rooms but not ideal for large open-plan areas
Ease of installation rating
9/10 - much easier to set up than gas or wood fireplaces because it does not need a flue
Safety features score
8/10 - electric fireplace design avoids real flames and combustion-related risks found in fuel-burning fires
Key benefits
- 2kW Heating: Provides practical supplementary warmth for small to medium rooms during cooler weather.
- Mantle-Style Design: Gives you a traditional fireplace look that helps anchor a living space visually.
- Electric Operation: Delivers fireplace ambience without wood, ash, smoke or gas refills.
- Freestanding Format: Easier to place in existing rooms without major renovation work.
- Flame Effect: Adds cosy visual atmosphere even when you want the look of a fire more than strong room heating.
- Low-Maintenance Use: Avoids the regular cleaning and fuel handling that come with solid-fuel fireplaces.
- Simple Everyday Controls: Makes it straightforward for most households to switch between ambience and heat settings.
- No Flue Required: Suitable for homes where installing a traditional fireplace would be impractical.
Q: Is the Dimplex 2kW Atlantic a built-in fireplace or a freestanding mantel suite?
A: It is a freestanding mantel-style electric fireplace suite, not a recessed insert. That makes it better suited to placing against an existing wall for a fireplace look, rather than building it into a cavity or chimney opening.
Q: How much room can the 2kW heater in the Dimplex Atlantic realistically warm?
A: A 2kW electric heater is typically suited to a small to medium room, around 15 to 20 square metres in a reasonably insulated home. It is designed for room heating rather than whole-home heating, so larger open areas may feel slower to warm.
Q: What does the 26-inch LED firebox mean in day-to-day use?
A: The 26-inch firebox refers to the visible fireplace insert size within the mantel suite. In practice, it gives a broader flame display than compact electric fires, but it is still a decorative room heater rather than a full-width built-in wall fireplace.
Q: What running cost should I expect from the Dimplex Atlantic on full heat?
A: At its full 2kW heating setting, it uses 2 kilowatt-hours of electricity for each hour it is heating. At a typical tariff of 30 to 40 cents per kWh, that is about 60 to 80 cents per hour while the heater is actively on.
Q: Does the Dimplex Atlantic need a chimney, flue or gas connection?
A: No, this electric fireplace does not need a chimney, flue or gas connection because it does not burn fuel. That makes it suitable for homes wanting the fireplace look without combustion venting, ash cleanup or gas plumbing requirements.
Q: How realistic is the flame effect on the Dimplex Atlantic compared with a real fire?
A: The LED firebox gives a flame-style visual effect without smoke, sparks or ash, so it is lower maintenance than a wood fire. It still will not reproduce the smell, crackle or strong radiant heat pattern of a real timber fireplace.
