Oil Filled Radiator Heaters -- 45 Models
An oil-filled radiator, also known as an oil heater or column heater, is a common form of convection heater used in domestic heating. Although filled with oil, it is electrically heated and does not involve burning any oil fuel - the oil is used as a heat reservoir.
A heating element at the base heats the diathermic oil, which has a high specific heat capacity and a high boiling point, so it transfers thermal energy efficiently while remaining liquid. Heat reaches the metal walls by convection, passes through them by conduction, and then warms the room through air convection and thermal radiation. The thin fins give a large surface area, so the surface stays safe enough to touch.

Three Things That Make These Heaters Different
Why Choose an Oil-Filled Radiator?
An oil-filled radiator is rarely the fastest heater in the shop — and it is almost always the one people leave running. Because the diathermic oil is a sealed heat reservoir rather than a fuel, the heater reaches its set temperature and then stops drawing power, while the fins carry on warming the room. That single design decision is behind everything below.
Six reasons oil-filled wins the long shift
Where it honestly loses
Head to head
| Oil-filled radiator | Electric fan / ceramic heater | |
|---|---|---|
| Time to reach set temperature | Around 20 minutes | Around 5 minutes |
| Heat after switch-off | Fins keep radiating — room stays warm | Stops as soon as the power cuts |
| Noise | None — there is no fan | Fan noise, more noticeable on long runs |
| Weight | 30 lb / 14 kg and up | Under 5 lb / 2.3 kg — one hand, any room |
| Power draw | Lower — element cycles off at set point | Higher — holds the temperature by running |
| Fire and tip-over risk | Wide base, no fan intake to block with dust | Light and easy to knock over — keep clear of soft furnishing |
| Surface temperature | Fins run hot; sustained contact can burn | Cabinet stays cooler to the touch on brief contact |
| Best suited to | Bedrooms, living rooms, all-night background heat | Quick top-up heat, small rooms, travel |
So which one should you choose?
Choose an oil-filled radiator if…
- You want warmth that is still there an hour after the thermostat clicks off
- The heater runs all night in a bedroom, so noise actually matters
- You are optimising running cost rather than sticker price
- You want a unit that will still be in service in ten years
Choose a fan or ceramic heater if…
- You need the room warm in five minutes and can live with the fan noise
- You move the heater between rooms, or take it travelling
- The budget is tight and the heater is for occasional, short use
- You need the smallest possible footprint
What that means for your order book
Almost every market we ship to buys both, and the split is predictable. Oil-filled radiators hold the mid and premium shelf — bedrooms, living rooms, overnight and long-shift use — where the buyer is choosing on running cost, quiet and lifespan instead of price. Fan and ceramic heaters take the entry price point and the seasonal top-up buyer. Our oil-filled line covers 7 to 13 fins and 1,500 W to 2,500 W across 45 models, with CE / LVD / EMC / GS / RoHS / ERP / CB marks and OEM colour, logo and packaging from 30 to 45 days. Tell us your market and we will suggest the mix.
