About Warm Room Report
A one-technician review desk for people who are tired of paying to heat empty rooms.
Warm Room Report is written by Marcus Ellery, a nate-certified hvac technician · 14 years in residential heating. Every heater covered here is judged on the same four questions: how fast it actually warms a room, what it costs to run, how safe it is when you forget about it, and whether you will still be using it in March.
How we test
- Each unit runs for at least two weeks in a real, poorly insulated house.
- Warm-up is timed at three feet from the outlet with a plug-in thermometer.
- Power draw is metered rather than taken from the box.
- Noise is measured at one metre, at the highest setting.
