10 Best Oil Heaters 2025 in the UK

The Russell Hobbs 1500W Oil Filled Radiator is a solid choice if you need a reliable heater for indoor spaces up to 15 square meters, like living rooms or medium-sized bedrooms. Its 1.5kW max power with three heat settings (600W, 900W, and 1.5kW) offers good flexibility to adjust warmth according to your comfort and energy use. The 7-fin design helps distribute heat evenly, which is a plus for consistent warmth.

This heater includes an adjustable thermostat, allowing you to maintain your preferred temperature without constantly turning it on and off. Safety is well covered with overheat and tip-over protection, offering peace of mind if you have pets or children around. Portability is decent thanks to built-in castors and carry handles, so you can move it easily between rooms, though at 7.7 kg it’s not the lightest model.

Oil-filled radiators like this one generally operate quietly as they don’t have a fan, making it suitable for bedrooms or quiet areas. The 1.45m power cord is a bit short, which might limit placement options near wall outlets. A two-year guarantee (one year standard plus a free second year with registration) adds value by protecting your purchase. While this heater is not ideal for very large spaces or outdoor use, it is well suited for users looking for steady, safe, and moderately portable heating in small to medium indoor rooms.

The Russell Hobbs 650W Oil Filled Radiator is a compact and portable heater designed mainly for small rooms up to 10 square meters, like bedrooms or small living areas. Its heating power of 650 watts is modest, so it won't heat large spaces quickly but is efficient enough for its intended room size. The heater features a variable thermostat, allowing you to adjust the temperature to your comfort, which helps save energy and maintain a steady warmth. Safety is well covered with overheat protection and tip-over safety cut-offs, providing peace of mind during use.

Portability is a strong point here thanks to its lightweight design (2.8 kg), built-in carry handles, and castors, making it easy to move between rooms. One possible downside is its relatively low maximum heat output, so it’s best suited for smaller spaces rather than heating whole floors or large rooms. Also, the 1.5-meter power cord might limit placement near power outlets without extension cables. The 2-year guarantee adds value by backing product reliability.

This heater is a solid choice if you want a safe, portable, and energy-conscious option for small rooms, but it may not meet needs for heating larger areas or very quick warm-ups.

The Pro Breeze Oil Filled Radiator is a solid choice if you want reliable and consistent heating for an indoor space like a home or office. With 2500 watts of power distributed across 11 fins, it heats rooms efficiently over long periods, making it more cost-effective compared to quick-fix fan heaters. You can easily control the warmth thanks to its adjustable thermostat and three heat settings (1000W, 1500W, and 2500W). The built-in 24-hour timer is a nice touch for saving energy by scheduling when the heater runs.

Safety is well covered with features like tip-over protection, overheat shutoff, and built-in heat protection, so it’s suitable even for rooms with children or bathrooms where safety is crucial. The heater is also designed to be portable despite its size, with four wheels, a carry handle, and cable tidy, making it easy to move between rooms and store away.

Weighing about 9.3 kg and having a slim profile, it fits easily in smaller spaces like under a desk or in a corner. For steady, low-maintenance heat with good safety and energy-saving options, this radiator is a dependable pick. If you need very fast heat or outdoor use, you might want to consider other types of heaters.
