But in case you are thinking about upgrading or replacing your current radiators this autumn and winter so they are the most energy efficient, Brits are being warned to look out for a costly trap.
It comes as heating experts are concerned that some radiators being sold in the UK don’t heat as much as the label suggests, meaning households could be left out of pocket and out in the cold.
Rob Nezard, managing director of UK Radiators, said shoppers are being misled by “bigger numbers” on radiator labels that don’t actually reflect real home heating.
Cheap and easy ways to insulate your home
Radiators are meant to be tested at certain temperatures to show how much heat they can give off.
But some companies are either using unrealistically high test temperatures to make radiators look more powerful than they’ll ever be in your home, or not testing them at all.
This could result in colder rooms, higher bills and more wasted energy, at a time when many households are financially struggling.
Rob explained: “When you buy a radiator, you expect it to keep you warm. But if the figures are exaggerated, you’ll never get the heat you’re paying for.
“It’s like buying a jumper labelled ‘extra thick’ that turns out to be paper thin.
Energy saving tips – what works and what’s just a myth
“Always check the radiator is tested at the same temperatures your home runs on – otherwise, you could be left cold and paying more.”
What do I need to know when buying a radiator?
Rob advised:
- Check the small print – radiators should show heat output for Delta T 50 (normal heating) or Delta T 30 (for heat pumps). Ignore higher numbers.
- Look for Watts (W) – this is the standard way heat should be shown.
- Ask for proof – a Declaration of Performance (DoP) shows the radiator has been tested properly.
- Don’t fall for “bigger number” marketing – it won’t mean more heat in your living room.
The Office for Product Safety and Standards (OPSS) is already working with industry bodies to make sure radiator advertising is accurate.
Companies found to be exaggerating could face action from watchdogs, Rob has said.
How to Save Money on Your Energy Bill
What temperature should a radiator be in a house?
With this in mind, making sure your radiators are set to the correct temperature in your house could typically save you more than £200. But how hot should they be in autumn and winter?
Stephen Hankinson, heating expert at Electric Radiators Direct explained: “The NHS suggests that once temperatures fall below 15°C, it’s a good idea to start heating your home. Ideally, aim to keep your living spaces at a minimum of 18°C (65°F).
“For maximum efficiency, I advise keeping your thermostat steady at around 18-21°C rather than constantly adjusting it up and down.
“A programmable timer or smart control makes this much easier, as you can set your heating to match your routine and avoid unnecessary usage.”
He added: “If your thermostat is attempting to reach a temperature of 22°C each day, you’re unlikely to notice the effect of dropping it a degree or two.
“Going by the latest average usage figures, dropping from 21 to 18°C could save £270 a year. Set your thermostat to a degree lower for a week and see how you go.”

Stephen has also recommended the ideal radiator temperature for each living space within your house:
- Bedroom: 16-18°C
- Living room: 18-21°C
- Kitchen: 18-20°C
- Bathroom: 22-24°C
- Children and baby rooms: 18-21°C
- Rooms for pets: 18-20°C (depending on breed and species)
