Dimplex Helmsdale Optiflame Review UK 2026
Quick verdict
Score: 6.6/10
Best for: A built-in focal point in a media wall or chimney breast
Not for: Heating a large or poorly insulated room - electric fires are supplementary heat
Bottom line: A practical electric fireplace (inset / media wall fire, 2kW) for a cosy focal point.
The Dimplex Helmsdale is an inset (recess) electric media wall fire with a fan heater and an LED flame effect. It is designed to be installed into a recess with a 9cm depth, combining heat settings of 1000W and 2000W with fan heating. Fit depends on the recess depth, since installation clearance affects how the unit sits in the wall.

Style and Installation
Style and installation follow an inset, media-wall approach, as this electric fireplace electric fire is designed to be recessed rather than used as a freestanding feature. The 9cm inset depth helps define the cavity requirement, so measuring the recess space is central to planning. Installation also depends on access behind the unit and the space available for the electrical connection before the fire is secured in place. The chrome styling is visible within the flame frame, which suits modern surrounds, although bulkier wall surfaces can restrict fit and alignment.
Heat Output and Room Size
Heat output and room size are best considered after the inset planning, as the Dimplex has a 2kW fan heater inset into a recess and requires the right space behind and around it to run safely. The fire has 1000 or 2000 watt settings, allowing warmth levels to be matched to the room. The inset recess depth of 9cm also affects positioning, as installation clearances need to be preserved.
Flame Effect and Realism
The electric fireplace is built around its flame effect, using an LED flame display set within an inset (recess) fire. In a media wall installation, the inset depth of 9cm helps keep the flame within the surround, so it sits more naturally in the overall viewing area. The LED design is intended to provide consistent brightness across typical viewing distances, and it includes controls for flame colours and brightness to suit different room lighting. As with many LED flame visuals, the texture can look less organic up close. Overall realism depends on placement and how far the fire is viewed from.
Controls and Features
Controls and Features matter because the flame look is only part of the Dimplex experience, and how the controls are set can affect how well it suits different rooms. This inset electric fire includes a 2kW fan heater with 1000 or 2000 watt settings, so heat output can be matched to the warmth level required. It also offers LED flame effect brightness regulation and a choice of flame colours, helping tailor the visual mood. For installation, the required inset depth is 9cm, so the controls remain reachable after recessing, although the exact positioning depends on the space available.
Who Is This For?
The electric fireplace electric inset fire is well suited to buyers looking for an inset, media-wall style installation with an adjustable flame effect, rather than a fixed display. It is designed for a recessed setup, with an inset depth of 9 cm. Heat output can be selected using the 1000 W or 2000 W settings, making it easier to match the level of warmth needed in the room. The chrome LED flame design aligns well with contemporary interiors where a built-in look is the priority.

Frequently Asked Questions
Is the electric fireplace worth it?
As a focal point built into a media wall or chimney breast, the Dimplex (inset / media wall fire) does the job, with 2kW 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 an inset / media wall fire, designed to be recessed into a stud wall, media wall or chimney breast. You'll need a correctly sized recess (check the required depth as well as the width and height) and a nearby socket or a spur fitted by a qualified electrician. Plan the opening before you build the wall - retrofitting a recess is far harder.
How much heat does the Dimplex give out?
The Dimplex Helmsdale is rated at 2kW. 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.
How realistic is the flame on the electric fireplace?
This electric fireplace uses LED flame effect. Flame realism is largely why people choose one electric fire over another, so it's worth looking at video of it running.
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.
