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.

How this site is funded

We earn a commission when you buy through our links, including the Amazon Associates programme and the official manufacturer link for our #1 pick. That never changes the ranking order — the specifications, prices, ratings and review counts on this site are recorded from the manufacturer's own checkout and from Amazon product pages, with the capture date stored alongside each figure.
