The GoHeater LED can be bought from sites including Amazon and for £19.99.
It provides instant heat and plugs directly into your wall socket, so there are no trailing cables to trip over.
The product is described as being ideal for bedrooms, study, offices, hotel rooms or chilly corners.
The features include a programmable digital control panel with adjustable temperature settings, and a 12-hour auto-stop timer, which costs “just pennies to run.”
One fan, going by the name on TikTok, praised the mini electric heater.
Simple energy saving tips
She said: “I'm so glad we got this little energy efficient plug-in heater for heating our hallway, stairs and landing.
“It heats up to 250 square feet so it packs quite a punch even though it's only 500 watts.
“It's programmable for up to 12 hours.
“We've currently set it for 20 minutes at a high speed.
“It's also got this lovely little night light that colour changes and yes it meets the UK CE standards.”
Rushing to the comments section of her video, another fan said: “I bought two that are great and throw loads of heat out.”
Someone else asked: “How much does it cost an hour to run?”
To which the creativelifeofmst replied: “It’s been costing us about 3p for 20mins as I only put it on for short bursts when needed. Not sure if that helps.”
How do I calculate my energy bill?
BELOW we reveal how you can calculate your own energy bill.
To calculate how much you pay for your energy bill, you must find out your unit rate for gas and electricity and the standing charge for each fuel type.
The unit rate will usually be shown on your bill in p/kWh.The standing charge is a daily charge that is paid 365 days of the year - irrespective of whether or not you use any gas or electricity.
You will then need to note down your own annual energy usage from a previous bill.
Once you have these details, you can work out your gas and electricity costs separately.
Multiply your usage in kWh by the unit rate cost in p/kWh for the corresponding fuel type - this will give you your usage costs.
You'll then need to multiply each standing charge by 365 and add this figure to the totals for your usage - this will then give you your annual costs.
Divide this figure by 12, and you'll be able to determine how much you should expect to pay each month from April 1.
