About Top Rated Plug-In Heaters

I plug in every heater myself, in my own drafty 1970s house.
We exist for one narrow job: helping people who are cold in one room choose a heater that fixes it without a nasty electricity bill. Every unit we rank is run through the same protocol in the same room, so the numbers are comparable rather than anecdotal.
We earn commissions from purchase links, including as an Amazon Associate. Those commissions pay for the site and the equipment. They do not buy position — the rank order comes from the weighted criteria below, and we publish the limitations of every pick, including our top one.
Prices and availability change constantly. We recheck them on each update and stamp the date on the page, but the retailer's own listing is always the final word.
Scoring criteria
- Time to warm (25%) — How many seconds until the air leaving the vent actually feels hot on your hands.
- Even coverage (20%) — Whether the far corner of the room catches up, or stays the spot nobody sits in.
- Running cost (20%) — What one warm room costs per evening compared with turning the central heat up.
- Safety behaviour (20%) — Overheat shutoff, tip-over response and how hot the outer shell gets to the touch.
- Living with it (15%) — Noise at night, cable clutter, controls you can use half-asleep, and where it stores.
Test protocol
- We ran each unit in the same 150 sq ft room at a 12°C start temperature and logged vent-air temperature at 10 seconds, 1 minute and 10 minutes.
- Coverage was measured with thermometers at three points, including the far corner, after 20 minutes of running.
- Noise was recorded at one metre on the highest setting, then again on the lowest, with the room otherwise silent.
- Safety behaviour was checked by blocking airflow and, for floor units, tilting them past 45° to confirm the cutoffs actually fire.
