Media walls with electric fires: what makes them work and what catches people out

angela • 30 June 2026

The media wall has become one of the most popular living room features in the UK right now — a TV mounted above an electric fire-effect insert, built into a chimney breast or purpose-built alcove, with everything hidden behind a clean, plastered finish.

Done well, they look genuinely impressive. Done badly, they look like a TV and a fake fire stuck to a wall. The difference usually comes down to planning and the quality of the installation.

At Pure Stoves and Fireplaces in Stevenage, we build and install media walls that combine a TV at the top with an LED fire-effect electric fire at the bottom, built into a chimney stack. Here's what we see go wrong when people don't think it through properly.

The proportions need to work for your room

The most common mistake is going too big. A media wall that looks spectacular in a showroom or on Instagram can completely overwhelm a modest living room. The TV height, the fire dimensions, and the surrounding framework all need to be scaled to the room, not to what looks dramatic in a photo.

We measure the room before we design anything. The goal is a feature that draws the eye without dominating the space.

The fire insert is the focal point — choose it carefully

In a media wall, the electric fire isn't just a heating source. It's the centrepiece when the TV is off, and the visual anchor when it's on. The quality of the flame effect, the depth of the insert, and how it looks at different brightness settings all matter more than people expect.

LED fire-effect electric fires have improved significantly in recent years. The better ones are convincing enough that guests ask whether it's a real fire. The cheaper ones look like a screensaver. We only install fires we'd put in our own homes.

Electrical and structural work needs to be right first time

A media wall involves cutting into walls, running new cable, managing heat from both the screen and the fire insert, and building a framework that carries significant weight securely. This isn't a job for a general handyman with a drill.

We handle the full installation — structural work, electrics, plastering, and finishing. Everything is done to the correct standard, and we won't cut corners to save time because the corners are what you're living with afterwards.

What the process looks like with us

We visit the room, take measurements, discuss your preferences on fire model and finish, and give you a fixed quote before any work starts. Installation typically takes one to two days depending on the complexity of the job. We leave the room clean.

If you're in Stevenage or the surrounding area and want to see what a media wall could look like in your home, get in touch with Pure Stoves and Fireplaces for a no-obligation consultation.

What size wood burner do I need?

by angela • 27 May 2026

Choosing the right size wood burner is one of the most important decisions you will make before installation. Go too small and you will be cold. Go too large and you risk wasting fuel, blackened glass, and a stove that never quite performs the way it should. This guide answers the most common questions homeowners ask when working out what size wood burner they need, so you can make a confident decision before you buy. How do I calculate what size wood burner I need? The standard calculation used across the industry is straightforward. Measure your room in metres, multiply the length by the width by the height to get the volume in cubic metres, then divide that figure by 14. The result gives you a good starting point for the kilowatt (kW) output you need. So for a room that is 5m long, 4m wide and 2.5m high: 5 x 4 x 2.5 = 50m³ divided by 14 = approximately 3.6kW That figure assumes average insulation and double glazing, which covers the majority of homes in the UK. If your property is older with poor insulation, single glazing, or significant draughts, divide by 10 instead. If you live in a new build with high-spec insulation and triple glazing, divide by 25. These adjustments reflect how much heat your room actually retains rather than what the bare volume suggests. Are kilowatt ratings on wood burners accurate? This is where many buyers get confused, and it is worth understanding before you shop. The kW figure quoted by a manufacturer is known as the nominal heat output. In the UK, manufacturers are largely free to set that figure themselves, provided a tester can confirm it is achievable with a reasonable fuel load. The problem is that "reasonable" is open to interpretation, which means two stoves both labelled as 5kW can have very different firebox sizes. A manufacturer may deliberately rate a stove at 5kW rather than a higher figure for practical reasons. Under UK building regulations, stoves with a nominal output of 5kW or below are often exempt from requiring a dedicated air vent in the room. That is a genuine selling point for many customers, so it creates an incentive to keep the rated output at or below that threshold. The honest conclusion is this: treat the kW figure as a guide, not a guarantee. Two stoves with the same rating can perform very differently in practice. What should I actually look at when comparing stove sizes? Once you have a rough kW figure in mind, the most reliable way to compare stoves is to look at the physical size of the firebox. The firebox is the internal combustion chamber where the wood burns. A larger firebox holds more fuel and can produce more heat over a longer period. When you visit a showroom, ask yourself how many logs the stove can reasonably hold without the door becoming difficult to close or logs rolling around. That physical capacity is a far more honest indicator of performance than the number printed on the specification sheet. At Pure Stoves and Fireplaces, our team will always walk you through firebox dimensions alongside kW ratings so you have a complete picture before making a decision. What if my calculation suggests I only need a 3kW or 4kW stove? A smaller output figure does not automatically mean you should buy the smallest stove available. If a 3kW or 4kW stove looks too compact for your space or would require you to cut logs down to a very small size, it is perfectly reasonable to step up to a 5kW model. A common concern is that buying a larger stove will make the room uncomfortably hot. In practice, the heat output of any stove is determined by how much wood you burn at any given time. A 5kW stove burning a small, well-controlled load will produce 2 or 3kW of heat, not the maximum output. You are always in control of the fire. The rated output simply tells you what the stove is capable of at full capacity. The only real downside to buying a stove that is slightly too large for the room is that you may end up with a large floor area inside the firebox where logs struggle to stay together. That is a minor inconvenience rather than a performance issue. What you genuinely want to avoid is buying a stove that is too small. A stove running flat out just to keep up with the room will wear faster, burn through fuel quickly, and still leave you cold on the worst winter days. Can Pure Stoves and Fireplaces help me work out the right size? Absolutely. Our team works with homeowners across Hertfordshire and the surrounding areas to find the right stove for the room, the property, and the budget. We stock a wide range of models across all output sizes and can walk you through dimensions, efficiency ratings, and installation requirements in our showroom. Whether you are looking for a compact 3kW stove for a smaller sitting room or a larger model to heat an open-plan kitchen and living space, we can help you find something that works.
