One Room in Your House Never Gets Warm? We Tested 18 Space Heaters. Only One Fixed It From the Wall

The furnace is running, the thermostat says 21°C, and the back bedroom is still cold enough to see your breath in the morning. Every Canadian house has that room: the basement office, the bedroom over the garage, the bathroom with the outside wall. So you buy a space heater, and it ends up on the floor at the end of a cord, cooking your ankles, in the way of the dog and the kids, while the far corner stays cold. Turning the furnace up just heats every other room to warm one, and the heating bill shows it.
So we put 18 space heaters and plug-in wall heaters through a January cold snap in three hard-to-heat rooms. The five worth comparing were Power Heat Pro, DREO Atom One, Lasko 751320, De'Longhi EW7707CM and the Lasko 755320 tower. Every heater was scored the same way: how fast the room warmed, how evenly the heat reached the corners, where the heater had to live, and how well it held the temperature we set.
- Room Heat-Up
- We logged the time from switch-on to a comfortable 21°C at the far side of a cold room, starting from 14°C.
- Even Warmth
- We measured the temperature in all four corners and at desk height. Some heaters warm your feet and nothing else.
- Placement & Safety
- We noted floor space, cords, hot surfaces and how easy it was for a toddler or pet to reach the heater.
- Controls
- Thermostat accuracy, timer, remote and modes: does it hold the temperature, or run flat out all evening?
One heater warmed the cold room fastest, reached the corners, and was the only one that came off the floor without an electrician: Power Heat Pro. Four more picks are below.
