13 best electric heaters to keep you warm when temperatures drop
Including the most energy efficient models, tried and tested by the GHI

When it's chilly, some rooms can feel impossible to warm up. That's where the best electric heaters can really help. From portable radiators to speedy fan models, heaters provide targeted warmth wherever they’re needed – whether that’s toasting your feet in the study or giving your bedroom a pre-sleep blast.
They do have a reputation for guzzling energy though, so it’s important to know you’re buying the most efficient electric heater possible. That's why the Good Housekeeping Institute set out to find the most effective and efficient models out there – and debunk some myths along the way.
With Amazon Prime Day back for October 2025, it's a great time to grab a bargain on our top-rated electric heaters. The event runs from 7-8 October and we're expecting bigger savings than ever. We’ll be updating this page with deals as they drop, so make sure you check back.

To test electric heaters, we first measure energy consumption at the highest and lowest settings for each model. We then assess how effective they are at warming a room, taking temperature readings at several distances. For fan heaters, we also measure fan strength and noise. You’ll find a detailed breakdown of how we test below our reviews.
All running cost calculations are based on the current (at time of writing) energy price cap of 26.35p per kWh.
