Are Portable Heaters Worth It in 2025? A Practical Guide for Keeping Warm
With heating bills still a concern for many households, more people are turning to portable heaters to warm specific rooms without firing up the whole central heating system.
But is it worth investing in one this winter? And which type should you choose?
Let’s break down the facts so you can decide what works best in your home.
Why Portable Heaters Are So Popular Again
For a lot of us, especially those living in older British homes with draughts or poorly heated rooms, portable heaters offer three big advantages:
- Instant warmth where you actually are
- Lower running cost compared to heating the whole house
- No installation, plumber, or electrician needed
They’re especially handy if you spend evenings in just one or two rooms, or you live in a property where upgrading the central heating isn’t practical.
The Two Main Types: Oil-Filled Radiators vs. Ceramic Heaters
Portable heaters generally fall into two categories, each with their own strengths.
1. Oil-Filled Radiators
Oil-filled radiators look like miniature radiators on wheels and work by heating oil inside the fins, which then releases heat slowly and steadliy.
Why People Love Them
- Cheap to run compared to other electric heaters
- Hold heat for a long time, even after switching off
- Quiet - perfect for reading, watching TV or working
- Safe & stable warmth (no exposed hot coils or fast airflow)
- Cost-effective for long periods of heating
Things to Keep in Mind
- Slower to heat up than Ceramic heaters
- Slightly heavier, though the castors make them easy to move
- Best used to maintain warmth over hours rather than “on-demand” bursts

2. Ceramic Heaters
Ceramic heaters use a ceramic heating plate and a small internal fan to push warm air into the room. They’re quick, efficient, and more energy-savvy than older traditional fan heaters.
Why People Love Them
- Warm a room very quickly
- Lightweight and extremely portable
- Energy-efficient, as the ceramic element heats up fast
- Built-in safety - many include tip-over & overheat protection
- Compact, ideal for small or awkward spaces
Ceramic heaters are highly responsive - perfect for quick bursts of heat or warming up a room that feels cold “right now”.
Considerations
- Not as quiet as oil-filled heaters (due to airflow)
- Heat stops immediately when you turn them off
- Not ideal for being left running for hours on end

Which One Is Cheaper to Run?
It depends on how you use them.
- Ceramic heaters are usually better for quick bursts - 10–30 minutes of warmth.
- Oil-filled radiators are usually cheaper for longer heating sessions, because once the oil is hot, it retains warmth without using as much electricity.
For older homes or rooms that get cold quickly, oil-filled heaters often save more money in the long run because you’re not constantly reheating the air from scratch.
How to Use Portable Heaters Efficiently
To get the best value:
- Shut the door to keep heat in the room
- Use a heater with a thermostat so it cycles on and off
- Pair it with draft-proofing for even better results
- Run it only in the room you’re using, not the whole house
These small habits can make a big difference to both warmth and running costs.

So… Are Portable Heaters Worth It?
Absolutely - when used wisely.
Portable heaters offer targeted, flexible warmth, and both oil-filled radiators and ceramic heaters have their place.
- If you want long-lasting, economical heat, choose an oil-filled radiator.
- If you want fast warmth, on demand, go for a ceramic heater.
Many households benefit from having one of each, using them depending on the time of day and the room being heated.
As energy prices remain unpredictable, portable heaters continue to be one of the simplest, most affordable ways to stay comfortable this winter.
