There’s a specific kind of cold that settles into certain rooms of a house—the conservatory on a crisp autumn morning, the spare bedroom that never seems to get enough radiator heat, or the home office where you find yourself shivering by midday. For me, it was the large, open-plan living area that, despite our central heating, always had stubborn cold spots. It’s a frustrating battle; you’re either wrapped in layers indoors or cranking up the main thermostat, sending your energy bills soaring. The search for a supplementary heating solution that is powerful yet efficient, safe, and doesn’t look like a relic from the 1970s is a familiar one. Ignoring the problem means abandoning entire sections of your home for half the year, which is simply not an option. That’s what led us to investigate modern solutions, and specifically, to put the De’Longhi HSX4324E.WH 2.4KW Convector Heater through its paces.

What to Consider Before Buying a Convection Heater
A convection heater is more than just an item; it’s a key solution for creating a comfortable and usable living space, especially in areas poorly served by central heating. Unlike radiant heaters that warm objects directly, convector heaters work by warming the air, which then circulates naturally to create a uniform ambient temperature. This makes them ideal for providing consistent, sustained warmth to an entire room. The main benefit is achieving a cosy environment without the noise and intensity of a fan heater or the slow start-up time of an oil-filled radiator. They are a silent, effective way to combat the cold.
The ideal customer for this type of product is someone facing inconsistent temperatures in medium to large-sized rooms (up to around 20-25 square metres, depending on ceiling height). They are perfect for homeowners with conservatories, extensions, or anyone looking to supplement their primary heating system in a specific zone, like a living room or master bedroom. However, it might not be the best fit for those needing instant, directional heat for a very small space, like under a desk—for that, a small fan heater might be more suitable. Similarly, for outdoor or workshop use, a more robust infrared heater would be a better choice.
Before investing, consider these crucial points in detail:
- Dimensions & Space: Convector heaters, especially powerful ones, can have a significant footprint. Measure your available floor space and consider the unit’s “slim style” design claims. A slim profile like that offered by the De’Longhi HSX4324E.WH 2.4KW Convector Heater is crucial for placement in high-traffic areas or smaller rooms where every inch counts.
- Capacity/Performance: The power, measured in watts (W) or kilowatts (kW), is the most important metric. A general rule of thumb is you need about 100W per square metre of room space. Therefore, a 2400W (2.4kW) heater is well-suited for rooms up to 24m². Look for features like multiple power settings and a thermostat, which allow you to tailor performance to the room’s needs and save energy.
- Materials & Durability: The build quality affects both longevity and safety. Look for a sturdy metal casing over cheap plastics. While most are designed to be lightweight for portability, ensure the base or feet are stable and robust to prevent wobbling or accidental tip-overs.
- Ease of Use & Maintenance: Modern heaters should be user-friendly. Digital displays, remote controls, and programmable timers significantly enhance the user experience. For maintenance, convector heaters are generally low-effort, but check for easy access to vents for occasional dusting to ensure optimal airflow.
Understanding these factors will help you choose a heater that not only warms your space effectively but also fits seamlessly into your lifestyle.

First Impressions: Sleek Design Meets Intuitive Controls
Unboxing the De’Longhi HSX4324E.WH 2.4KW Convector Heater, the first thing we noticed was its genuinely slim and modern aesthetic. De’Longhi has done an excellent job of creating a heater that doesn’t scream for attention. The crisp white finish and minimalist lines allow it to blend into the background of a room rather than being an industrial-looking eyesore. It feels lightweight yet solid, and the integrated carry handles are a thoughtful touch, making it easy to move from room to room. Assembly was refreshingly simple, involving just a few screws to attach the two pedestal feet, which provide a stable base. Once plugged in, the digital LED display comes to life. It’s bright, clear, and easy to read from a distance. The controls are intuitive, and within minutes, without even glancing at the manual, we had cycled through the power settings, set the thermostat, and explored the timer function. This immediate sense of quality and user-friendliness sets a positive tone for its performance.

Performance Deep Dive: Putting the De’Longhi HSX4324E.WH to the Test
A heater’s true worth is measured in warmth and efficiency. We put the De’Longhi HSX4324E.WH 2.4KW Convector Heater through a series of real-world tests in a notoriously cold 50m³ conservatory to see if its performance lived up to its premium branding. We analyzed its heating capability, the intelligence of its controls, and its overall design and safety credentials.
Heating Performance and The Lateral Fan Advantage
The core promise of any heater is, of course, to heat. With a formidable 2.4KW heat output, the De’Longhi HSX4324E.WH has plenty of power on paper for its stated 60m³ coverage. We set it up in the conservatory on a chilly 8°C afternoon. On its maximum setting, the effect was impressively rapid. Within 15-20 minutes, the chill was noticeably gone from the air, and within 45 minutes, the entire space had reached a comfortable ambient temperature. This is where the standout feature, the lateral fan system, truly shines. Standard convector heaters rely on slow, natural air currents, which can lead to heat pooling at the ceiling and leaving the floor level cool. De’Longhi’s system uses a gentle fan to actively push the warm air out from the sides of the unit, creating a much more effective and uniform circulation. We could feel the difference; there were no distinct hot or cold spots in the room. The warmth felt evenly distributed, from the sofa corner to the far window. This fan-assisted convection is a feature that really sets it apart from more basic models and justifies its position in the market. The fan itself is not silent, but it’s a very low hum, far less intrusive than a traditional fan heater and easily masked by conversation or a television.
Intelligent Comfort: Digital Controls and Eco Functionality
Power is nothing without control, and this is where the De’Longhi HSX4324E.WH excels. The digital control panel is a significant upgrade over the vague analogue dials found on many competitors. The digital thermostat is the hero here. We set our desired temperature to 21°C, and the heater worked intelligently to reach and maintain it. It would run at full power initially, then cycle on and off automatically to hold the temperature steady, preventing the room from becoming stuffy and wasting electricity. This precision is not just about comfort; it’s about efficiency. The 24-hour timer is another incredibly practical feature. We programmed it to turn on an hour before we typically use the living room in the morning. Waking up and walking into an already warm space feels like a small luxury, but it makes a huge difference to the start of your day. The Eco Plus Function is an intelligent addition that automatically modulates the power level and thermostat setting based on the current room temperature, aiming to find the optimal balance between comfort and energy consumption. While its exact energy savings are hard to measure in a short test, the principle is sound and adds to the unit’s credentials as a smart, modern heating appliance.
Design, Portability, and Uncompromising Safety
Beyond its heating prowess, the physical design and safety features of the De’Longhi HSX4324E.WH are top-notch. Its slim profile, at just a few inches deep, means it can be placed against a wall without being obtrusive. This is a huge benefit in smaller rooms or hallways. Despite being lightweight enough to move easily using the built-in handles, the pedestal feet give it a very stable base, and we never felt it was at risk of being accidentally knocked over. However, accidents can happen, especially in households with children or pets. This is where De’Longhi’s focus on safety becomes critically important. The heater includes a digital tip-over safety switch. We tested this by tilting the unit, and it shut off instantly, accompanied by an audible alarm. This immediate, clear alert system provides invaluable peace of mind. Furthermore, a standard safety thermostat prevents the unit from ever overheating. These features aren’t just marketing bullet points; they are essential protections that make you feel confident leaving the heater running unattended, such as when using the timer to pre-heat a room. It’s this combination of elegant form, practical portability, and robust safety that elevates the overall user experience.
What Other Users Are Saying
While our hands-on testing of the product’s performance was overwhelmingly positive, it’s important to consider the entire purchasing experience. A look at user feedback reveals a recurring theme that is crucial for potential buyers to be aware of. Several users have reported issues not with the heater itself, but with the fulfilment process. Reports include receiving units that appeared to be used, with missing components like screws for the stand, or in one case, receiving an entirely different, lower-spec model (the HSX2320) in the correct box. These comments suggest occasional problems in the supply chain or warehouse handling rather than a defect in the De’Longhi product. This feedback is relevant as it underscores the importance of a simple action: upon delivery, immediately inspect your heater. Ensure the box is sealed, all parts are present, and the model number on the unit matches the one on the box. While likely an infrequent issue, being a vigilant consumer ensures you get the excellent product you paid for.
How Does the De’Longhi HSX4324E.WH Compare to the Alternatives?
No product exists in a vacuum. To understand its value, we need to compare the De’Longhi HSX4324E.WH 2.4KW Convector Heater to other popular models on the market. Here’s how it stacks up against three notable competitors.
1. De’Longhi HSX2320 Slim Convector Heater
As the smaller sibling in the same product family, the De’Longhi HSX2320 offers a similar slimline aesthetic but with a lower power output of 2.0kW. This makes it better suited for smaller rooms, up to around 20m² or 50m³. It typically features more traditional analogue controls—a simple adjustable thermostat and power selection dials—rather than the precise digital display and timer of the HSX4324E.WH. For someone needing to heat a smaller bedroom or study and who doesn’t require advanced programming features, the HSX2320 is a very capable and more budget-friendly alternative from the same reputable brand.
2. Igenix IG5300 3000W Convector Heater
For those who prioritize raw heating power above all else, the Igenix IG5300 is a compelling option. With a massive 3000W (3.0kW) output, it’s designed to heat very large spaces quickly. However, this power comes with a trade-off in features. Like the smaller De’Longhi, it relies on a basic adjustable thermostat and does not offer the timer, Eco modes, or digital precision of the HSX4324E.WH. It’s a workhorse heater for large, cold areas like garages, workshops, or big open-plan living rooms where smart features are less important than sheer heat output.
3. Duronic HV102 Oil Free Convection Heater
The Duronic HV102 introduces a different heating technology into the mix: micathermic. Using mica panels, it produces both convection heat (warming the air) and radiant heat (warming objects and people directly). This can create a more pleasant, all-encompassing warmth. It’s oil-free, making it lighter and faster to heat up than traditional oil-filled radiators. While it offers a great alternative heating sensation and is highly portable, it lacks the fan-assisted circulation of the De’Longhi HSX4324E.WH, meaning heat distribution might be slower and less uniform in a large space. It’s an excellent choice for those who prefer the feel of radiant heat.
Our Final Verdict: Is the De’Longhi HSX4324E.WH Worth It?
After extensive testing, we can confidently say that the De’Longhi HSX4324E.WH 2.4KW Convector Heater is a superb heating solution that successfully bridges the gap between raw power and intelligent control. Its potent 2.4KW output, amplified by the highly effective lateral fan system, delivers fast, uniform warmth to even challenging spaces. What truly elevates it, however, are the smart features: the precise digital thermostat, the convenient 24-hour timer, and the reassuringly robust safety mechanisms. It’s a device designed for modern living, where efficiency, safety, and user experience are just as important as heat.
We recommend it wholeheartedly for anyone looking to tame a cold conservatory, large living room, or any medium-to-large space needing consistent, controllable heat. It offers a significant upgrade over basic models, providing a level of comfort and convenience that justifies its price. If you’re tired of cold spots and high energy bills from inefficient heating, this model is a fantastic investment in home comfort. Ready to experience a new level of warmth and control?
