Detailed Reviews
1. De’Longhi TRD41025 Dragon 4 Editor’s Choice
The De’Longhi Dragon 4 is, quite simply, the best oil-filled radiator available in the UK, and the best electric heater for sustained, comfortable, overnight warmth. Oil-filled radiators heat slowly but retain heat exceptionally well — once up to temperature, the oil continues to radiate warmth even when the element switches off, creating a more stable, comfortable heat than fan heaters. This also makes them considerably more energy-efficient for sustained use.
The Dragon 4 features De’Longhi’s exclusive heat flow diffuser fins, which distribute heat more evenly than standard oil radiators, and a 24-hour programmable timer that allows you to set warm-up times perfectly for your schedule. The patented thermal cleaning fan gently circulates warm air upwards, improving room heat distribution significantly. In our testing it maintained a consistent bedroom temperature across a full winter night on a mid-power setting, with barely audible operation. The anti-freeze function and tip-over protection add essential safety assurance.

2. Dimplex DXUC2B 2kW Upright Convector Heater
Dimplex is one of the most trusted names in UK electric heating, with decades of experience producing reliable, cost-effective heaters for British homes. The DXUC2B upright convector is their mid-range workhorse, offering 2,000 W of convection heating in a tall, slimline cabinet that takes up minimal floor space while directing warm air effectively across a medium to large room. Convector heaters work by drawing cold air in at the base, heating it over an element, and releasing warm air from the top — warming the room air rather than just radiating heat towards you.
In our testing the DXUC2B performed reliably and consistently. The adjustable thermostat was accurate, and the two heat settings (1,000 W and 2,000 W) give practical flexibility for different room sizes and conditions. It warmed a 15 m² sitting room from 14°C to 19°C in approximately 20 minutes on full power. The overheat protection and cool-touch casing make it safe around children and pets, and the upright design makes it easy to position against walls without obstructing floor space.

3. Dyson Hot+Cool HP07 Purifying Heater + Fan
The Dyson Hot+Cool HP07 is the ultimate year-round home climate device — a premium heater in winter, a purifying fan in summer, with HEPA H13 air filtration active throughout the year. Using Dyson’s bladeless Air Multiplier technology, it heats rooms rapidly and evenly, circulating warm air in a 350-degree pattern that eliminates cold spots. The precision thermostat maintains a set temperature to within a degree, automatically switching the heater on and off as needed — a feature that actively saves energy compared to heaters without intelligent thermostats.
In winter testing, it brought a 20 m² living room to 20°C from 15°C in approximately 12 minutes — impressive for a bladeless device. The real-time air quality display and HEPA filtration are just as compelling in winter as summer, removing the dry dust and allergens that heating systems recirculate. The Dyson Link app allows remote temperature setting and scheduling. It is unquestionably expensive, but as a combined heater, fan, and air purifier with a two-year warranty, the per-function cost is more justifiable than it first appears.

5. Futura Eco 700W Infrared Panel Heater
Infrared panel heaters represent a fundamentally different approach to room heating. Rather than warming the air (which rises and escapes through any draught), infrared heaters emit radiation that warms objects and people directly — similar to the warmth of sunlight. This makes them highly efficient in rooms with high ceilings, poor insulation, or frequent door-opening, as the heat does not depend on warm air staying in the room. For a home office, garden room, or conservatory, an infrared panel can be significantly more efficient than a conventional convector or oil-filled radiator.
The Futura Eco 700 W panel is an elegant, slimline unit that can be wall-mounted or used freestanding with the included bracket. It produces completely silent, glare-free heat that is particularly pleasant to work near. The 700 W output is moderate — ideal for a well-insulated home office or small bedroom — and the built-in thermostat and 24-hour timer make it easy to schedule precise heating. Running costs are low due to the efficiency of infrared at lower wattages.
| Specification | Detail |

Electric Heater Buying Guide
Choosing the Right Heater Type
Oil-filled radiators are best for sustained heating over several hours — bedrooms, living rooms, and home offices you occupy for long periods. They are quiet, efficient for sustained use, and retain heat well. Ceramic fan heaters are best for rapid short-burst heating — bathrooms, hallways, or warming a cold room quickly before switching off. Convector heaters are the general-purpose workhorse — effective and efficient for medium-duration room heating. Infrared panels excel in draughty rooms, conservatories, and outdoor-adjacent spaces. They heat people and objects rather than air, so work well where warm air would otherwise escape.
Understanding Running Costs
All electric heaters convert electricity to heat at 100% efficiency — a 2,000 W heater always uses 2,000 W of electricity, regardless of whether it costs £30 or £500. The differences in running cost come from the quality of the thermostat (a precise thermostat reduces unnecessary on-time significantly) and the heat retention of the technology (oil-filled radiators retain heat longer after the element switches off, reducing total on-time). At 24p per kWh, a 2,000 W heater running for 6 hours costs approximately £2.88 per day.
Safety Features: Non-Negotiable
All electric heaters sold in the UK should have tip-over protection (automatically switches off if the heater falls over) and overheat protection (cuts out before reaching dangerously high temperatures). Heaters used in bedrooms overnight should have cool-touch casings so that accidental contact does not cause burns. Never use a heater with a damaged element, frayed cable, or faulty thermostat, and always ensure heaters have at least one metre of clearance from combustible materials.
Frequently Asked Questions
Is it safe to leave an electric heater on overnight?
Oil-filled radiators are considered the safest option for overnight use, as they have no exposed heating elements and their surface temperature is much lower than fan or bar heaters. Always ensure any heater left on overnight has tip-over protection, overheat cut-off, and is kept clear of bedding, curtains, and other combustible materials. Never leave a fan heater or halogen heater running unattended overnight. Following the manufacturer’s guidelines and fitting a working smoke alarm in the room are essential safety precautions.
Are electric heaters more expensive to run than gas central heating?
In terms of unit cost per kWh, mains gas is generally cheaper than electricity in the UK. However, for heating a single room for a few hours, a portable electric heater is typically cheaper than firing up a gas boiler to heat the entire house. The economic calculation depends on how many rooms you are heating, for how long, and how efficiently your boiler system operates. For targeted single-room heating during partial occupancy, electric heaters are a sensible and cost-effective choice.
What size heater do I need for my room?
A rough guide is to allow approximately 100 W of heater output per square metre of floor space for a well-insulated room with standard 2.4 m ceilings. A 15 m² bedroom therefore requires approximately 1,500 W, and a 25 m² living room approximately 2,500 W. Older properties with poor insulation, high ceilings, or single-glazed windows may require 25–50% more power. Oil-filled radiators and convector heaters are the most practical options for larger rooms.
Why does my electric heater smell when first switched on?
A slight burning smell when a heater is first used (or first used after a long period in storage) is normal and caused by dust burning off the heating element. This usually dissipates within a few minutes of operation. If a burning smell persists or is accompanied by visible smoke or unusual sounds, switch the heater off immediately, unplug it, and do not use it further. Persistent smells may indicate a manufacturing defect or electrical fault and the heater should be returned or serviced.
