10 Best Room Heaters 2025 in the UK

The Russell Hobbs 650W Oil Filled Radiator is designed for small rooms up to about 10 square meters, making it a good choice for bedrooms or small living spaces. Its 5 fins help spread warmth evenly without the noise of fan heaters, so it runs quietly. The adjustable thermostat lets you control the temperature to save energy, which is useful since 650 watts is moderate power, helping keep electricity bills lower.

Safety is well covered with overheat and tip-over protection, giving peace of mind, especially if you have kids or pets. The heater is fairly lightweight at 2.8 kg and comes with carry handles and wheels, making it easy to move between rooms. On the downside, this model is best suited for smaller areas due to its lower heating capacity, so it might struggle to warm larger rooms quickly.

Also, because it uses oil heating, it takes a bit longer to heat up compared to fan heaters, but it keeps warmth for a while after being switched off. This makes it a reliable, safe, and quiet heater that fits well if you need a portable, energy-efficient solution for small spaces.

The De'Longhi Dragon 4 TRD41025T is an oil-filled radiator designed for indoor use, offering reliable and steady heating. It has a decent maximum power output of 2.5 kW with three heat settings, allowing you to adjust warmth according to your room size and comfort level. This model uses an enhanced chimney effect to push hot air through vents efficiently, which helps warm up spaces faster than some other oil heaters. Energy-wise, it operates between 1100W and 1400W on medium and low settings, which is fairly typical for this type of heater, giving you some flexibility to save power.

One of its standout features is portability – it comes with pre-assembled wheels and a carry handle, making it easy to move around your home. It also has a sleek white finish and a compact pedestal design that fits well in most rooms. The unit weighs about 17.5 kg, so while it’s not super light, the wheels and handle help with transport.

A notable benefit is the long 10-year warranty, showing confidence from the manufacturer in its durability. The radiator is bulkier compared to portable fan heaters and takes a bit longer to heat a room initially, so it’s best suited for those prioritizing lasting warmth and energy efficiency over instant heat. This heater is suitable for users wanting a quiet, effective, and mobile oil radiator with reliable heating power and a stylish look, ideal for medium-sized rooms.

The Dreo Smart Electric Space Heater is a versatile room heater that offers a powerful 1500W ceramic heating system, making it suitable for quickly warming small to medium-sized rooms. It stands out with its advanced PTC heating system and heat funnel design, which enhances air circulation and efficiency. This heater's smart features, such as compatibility with Alexa and Google Home, the Dreo app for remote control, and a precise thermostat, allow for convenient and energy-saving operation.

The multiple heating modes and 12-hour timer also provide flexibility to cater to different heating needs and schedules. Safety is a significant strength, with features like tip-over protection, overheat protection, and child lock, ensuring peace of mind during use. Additionally, the heater operates quietly at 34dB, making it ideal for bedrooms and quiet spaces. Its lightweight and portable design, complete with a carry handle, enhances its usability around the home.

However, one potential drawback is that it’s primarily designed for indoor use, limiting its versatility. Additionally, for some, the reliance on smart technology for full feature access might be a disadvantage if they prefer more traditional controls. Despite these minor limitations, the Dreo Smart Electric Space Heater is a reliable and efficient choice for those seeking a blend of performance, convenience, and safety in their home heating solutions.
