The DREO tower heater wins, and it wins on the
test that matters most. It shut down under a pillowcase in 24 seconds having
let the fabric reach only 190°F, the coolest result in the group by a wide
margin, and it produced the most heat of any heater tested at 1,536 watts. It
avoided the startup power spike that most of this field shows, hitting only
1,648 watts against the Amazon Basics' 2,010, and it runs at 37.7 dB on low.
At $90 it is not cheap, but nothing here does more things well.
The $440 Dyson finishes second at 3.7 and is genuinely impressive in places —
1,518 watts with no spike at all, 350° oscillation, an air purifier built in,
and no clicking thermostat to wake you up. The problem is that it ran for five
minutes and seven seconds under a pillowcase before shutting itself off. It
never got dangerously hot at 320°F, because it moves too much air to
concentrate heat, but five minutes is a long time to rely on that.
For under $50 the Lasko is the clear pick. Its overheat protection cut out in
24 seconds at 291°F, matching the DREO tower's reaction time, and it runs
quieter than average with a broadcast result in the middle of the field. Among
the sub-$30 heaters, the JIBUFI at $28 is the standout: best oscillating
performance in the test, third-best heat broadcast overall, and a proper
alarm-and-cooldown tip-over routine.
Two products are worth avoiding. The Aikoper at $26 melted plastic on contact
when tipped, then smoked for 2 minutes and 12 seconds up to 437°F before its
overheat protection engaged — past the ignition temperature of ordinary
household fabric. Mr. Heater's propane unit is a fine camping heater and is
nearly silent, but as a room heater it cannot push heat anywhere, its grill
melted plastic, and it set the test fabric on fire. Neither belongs near
curtains or bedding.
