Style and Installation
When planning this electric fireplace inch electric fireplace suite installation, the first step is to confirm that the 23 inch (107 cm) overall width fits the intended wall space. As a fully assembled suite that includes both the fire feature and the surround, the surround design determines the finished look, including the integrated hearth profile for different room styles. Installation typically starts with marking the centreline, checking the wall surface is suitable for mounting, and ensuring safe access for the mains connection. Where wall fitting alignment is critical, professional installation can reduce installation risk. Remote positioning should also be factored in before final positioning.
Heat Output and Room Size
Heat output and room size are important considerations for the Dimplex inch electric fireplace suite, because a 23 in (107 cm) wide fireplace feature primarily functions as a focal point. Room size should therefore be matched to the level of heating needed, with placement in a smaller lounge, bedroom, or snug space often more appropriate. For larger rooms, supplementary heating alongside central heating may be the practical approach, as standalone coverage is not confirmed by the available information.
Flame Effect and Realism
The electric fireplace inch electric fireplace uses an LED flame effect intended to create a realistic fire look from typical viewing distances in a living room. The flame display fills the opening at around 107 cm wide, helping the effect blend in under normal ambient light. With brightness not overly reduced, the flame shape appears more continuous and the edges look less distinct. Up close, the imitation cues can be more noticeable, including a flatter look compared with true logs. For best realism, the effect is typically suited to seated angles rather than a direct front view.
Controls and Features
How easy are the controls to use day to day on the Dimplex inch fireplace suite? The suite is designed around remote control, so day to day changes can be made without reaching the fireplace itself. The remote supports choosing flame colours and adjusting flame brightness, which helps match room light levels. It also allows quick switching of the visual effect, since the flame display is the main feature being changed.
Who Is This For?
The electric fireplace inch electric fireplace suite is aimed at people who want a ready-to-use flame effect display without assembling separate components, because it is described as a fully assembled fireplace with surround. With a width of 23 inches (107 cm), it suits smaller spaces where a compact focal point is preferred. The remote control, adjustable flame brightness and the option of different flame colours make it suitable for straightforward everyday operation. This model is best viewed as a decorative unit in the stated setup, rather than a platform for additional features where detailed installation options and technical specifications are not provided.
Where to Buy in the UK
Finding the Dimplex Portland 23 inch suite in the UK is largely about locating listings that specify the "23 inch" size (107 cm wide) and confirm the product is sold as a fire with a surround (fully assembled). Shoppers should check that the listing matches the Dimplex name and describes a complete bundled suite rather than showing components separately (not stated). Retailer pages should also be checked for the remote control, flame colour options, and adjustable flame brightness, as these details can differ by listing. Availability can change, and returns vary by seller.
Frequently Asked Questions
Is the electric fireplace worth it?
As a complete fireplace with its own surround, the Dimplex (fireplace suite (fire + surround)) does the job. 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 fireplace suite (fire + surround), so it comes as a complete unit with its own surround and sits against a flat wall. No recess or chimney is needed - you just need floor space and a socket. Suites suit rooms without an existing fireplace, giving you the full look in one purchase.
What size is the Dimplex?
The Dimplex Portland 23 measures 23in 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 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.
What features does the Dimplex have?
The electric fireplace offers remote 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.
