Are infrared heaters cheaper to run than fan heaters or oil-filled radiators?

Are infrared heaters cheaper to run than fan heaters or oil filled radiators?

When winter hits and the temperature drops, many of us face the same question: what’s the most cost-effective way to stay warm? With energy prices still high and a cost-of-living squeeze, the heating solution you choose really matters.

So, are infrared heaters actually cheaper to run than fan heaters or oil-filled radiators? And how much could you really save?

Let’s compare three popular electric heating options and the basic raw numbers:


Fan Heater

Uses around 2kW per hour

Oil-Filled Radiator

Typically 1.5kW per hour

Infrared Panel Heater

Often around 0.6kW per hour.

Assuming 5 hours of daily use over 5 months (approx. 150 days):

Fan heater

2kW x 5h x 150d = 1,500kWh → ~£510 per winter (at £0.34/kWh)

- Oil-Filled Radiator

1.5kW x 5h x 150d = 1,125kWh → ~£382

Infrared Panel Heater

0.6kW x 5h x 150d = 450kWh → ~£153

Saving over £350 vs a fan heater. That’s nearly the cost of a weekend away. Or your broadband and Netflix for the year.

The Tale of Two Rooms

Meet John and Fred.

John plugs in his fan heater every night for the winter. It’s noisy, kicks up dust, and costs him over £500 per year.

Fred installs an infrared panel. It’s silent, slimline, and costs him just £153 to run through winter.

After three years, Fred’s saved over £1,000. Enough for a home office upgrade, or a family holiday.

The difference? Same warmth, smarter source.

What’s behind this?


Infrared heats objects and people, not the air.

That means quicker warmth, fewer cold spots, and better comfort at lower ambient temperatures.

It’s also low maintenance, discreet, and safe for continuous use even in bedrooms and studies.

And while it’s not always the best fit for every room, when it’s right, it’s hard to beat.
