Oil filled Radiators

A warmer, quieter home – efficient heating you can trust

Stay cosy through the cold with oil filled radiators that deliver long-lasting warmth without the noise. Energy-efficient, portable, and safe for any room—perfect for creating a warm space.

Oil filled Radiators

An oil filled radiator is a type of electric heater that uses a special heat-conserving oil as a thermal reservoir. Contrary to what the name might suggest, the oil is not burned; instead, it is permanently sealed within the unit and acts as a heat reservoir that transfers warmth to the radiator’s surface and then into the room. Once plugged in, electricity heats the internal element, which in turn heats the oil. The warmth is then evenly radiated throughout the room, even after the unit has been switched off.

Benefits of oil filled radiators

Long-lasting heat even after switch-off

Oil filled radiators retain warmth long after they’re turned off, thanks to their thermally efficient oil reservoir. This means you continue to feel the heat without continuous energy consumption—ideal for cold UK evenings when you want lasting comfort without leaving the unit on all night.

Exceptionally energy efficient

These heaters use electricity to warm oil that stays hot for a prolonged period, reducing the frequency of active heating. This not only conserves energy but also helps lower your electricity bills—something every household can appreciate as energy costs climb.

Whisper-quiet operation

With no noisy fans or moving parts, oil filled radiators are virtually silent. Whether you’re working from home, reading in peace, or trying to get a good night’s sleep, they deliver uninterrupted warmth without the background hum.

Maintenance-free convenience

Once plugged in, oil filled radiators require virtually no upkeep. The oil is permanently sealed, there are no filters to clean or elements to replace, and they’re built to last—making them one of the easiest heating solutions to own.

Built-in safety for peace of mind

Modern models feature automatic shut-off if tipped over, overheating protection, and cool-touch exteriors. These safety measures make them a smart choice for families with children or pets, offering reassurance during daily use.

Easy to move and reposition

With wheels and integrated handles, oil filled radiators are highly portable. You can roll them from room to room, heating just the spaces you use. This zonal heating approach helps reduce waste and tailor warmth to your routine.

Programmable thermostats and timers

Many units include digital thermostats and programmable timers, allowing you to set specific temperatures and schedule heating periods. Wake up to a warm room or come home to comfort—without wasting energy during the hours you’re away.

Ideal for rooms without central heating

Oil filled radiators work independently, making them perfect for conservatories, garages, lofts or spare rooms not connected to central heating. They’re especially useful in rentals or older homes where full heating upgrades aren’t feasible.

A greener heating option

Because they operate efficiently and use electricity (which can come from renewable sources), oil filled radiators are a cleaner alternative to gas or wood-based systems. They’re a small but significant step toward more sustainable living.

How oil filled radiators compare to dry thermal and ceramic stone radiators

Oil filled radiators: Reliable, silent and budget-friendly

Oil filled radiators are popular for their silent operation, low running costs and excellent heat retention. Once heated, the internal oil remains warm for a long time—even after switch-off—making them great for consistent background heating. They’re also portable, low maintenance, and typically more affordable upfront than other advanced electric heating options.

Best for: Occasional use, zonal heating, bedrooms, home offices, or renters looking for low-cost and moveable warmth.

Dry thermal radiators: Fast and responsive, but less residual heat

Dry thermal radiators, also known as dry electric radiators, use aluminium or similar conductive materials to heat up quickly. They’re responsive and ideal for rooms where instant warmth is needed. However, they cool down just as fast once switched off, offering little residual heating. They can also be slightly noisier due to expansion and contraction sounds.

Best for: Fast heat in well-insulated rooms, or for people needing short bursts of warmth with precise control.

Ceramic stone radiators: Superior heat retention with a sleek finish

Ceramic or stone-core radiators contain a thermal mass—usually ceramic plates or natural stone—which absorb and radiate heat gradually. They offer excellent heat retention and can maintain warmth long after being turned off, much like oil filled models but often with more stylish, wall-mounted designs. They’re typically hardwired, which means professional installation is required and portability is limited.

Best for: Whole-room heating in permanent spaces like living rooms or kitchens, especially where design and efficiency are both priorities.

Choosing the right oil filled radiator

Room size and heat output (wattage)

The size of the space you’re trying to heat should guide the wattage you choose. As a rough guide, you’ll need around 100 watts per square metre. So, a small bedroom might be fine with a 1000W unit, while a larger living room may require something closer to 2000–2500W. Choosing the right output ensures efficient heating without wasting energy.

Thermostatic control

A built-in thermostat helps maintain a steady temperature by switching the unit on and off as needed. This saves energy and avoids overheating. Many modern models offer digital displays and precision settings, so you’re always in control of the warmth in the room.

Timer and programmable features

A 24-hour or weekly timer lets you schedule when the radiator turns on and off—ideal for heating a room before you wake up or return from work. Some advanced models even offer Wi-Fi or smart plug compatibility for app-based control.

Portability and design

If you plan to move your radiator between rooms, look for one with sturdy castor wheels and a carry handle. For more permanent placement, sleeker panel-style designs may blend better with your décor. Some even come with wall-mounting options.

Safety features

Overheat protection and tip-over shut-off functions are essential for peace of mind—especially in homes with pets or children. Cool-touch surfaces are another bonus, reducing the risk of burns.

Noise level

Most oil filled radiators are silent in operation, but check customer reviews or manufacturer notes for any mention of ticking noises (from thermostats switching). For bedrooms or workspaces, go for models that emphasise quiet performance.

Energy-saving modes

Some radiators come with eco modes or adaptive start features, which optimise performance based on your habits or room conditions. These smart functions can help reduce your electricity bill over time without sacrificing comfort.
