What Fin Count Actually Means
Oil radiators are measured in fins — the more fins, the more surface area and the faster they heat a room.
Running Costs
At 24.5p/kWh (October 2026 price cap). An oil radiator on medium for 6 hours.
| Radiator | Watts (medium) | Per hour | Per day (6h) | Per month |
|---|---|---|---|---|
| 7-fin 1500W | 1000W | £0.24 | £1.47 | £44.10 |
| 9-fin 2000W | 1300W | £0.32 | £1.91 | £57.33 |
| 11-fin 2500W | 1700W | £0.42 | £2.50 | £74.97 |
These are estimates at the medium heat setting. Using the built-in thermostat to cycle on/off cuts actual costs by 30–50%. A timer (included on most) lets you pre-heat the room before you get home then switch off.

Why Geepas Dominates the Budget Space
Geepas is the only brand offering five different oil-filled radiator modelsunder £70, three of them under £50. Compare that to De’Longhi where the cheapest oil radiator starts at £80+. The build quality is solid for the price — metal fins, mechanical or digital thermostat, 2-year warranty — and with free next-day delivery, there’s no hidden shipping cost.
If you’re heating a bedroom or home office and don’t want to turn on the central heating for one room, a £36 Geepas 7-fin will pay for itself in about three weeks of targeted use. The maths is simple: central heating costs £2–4/hour for a whole house. An oil radiator costs 25–42p/hour for one room. That’s an 85–90% saving every time you use it.
