Vornado AVH10 Whole Room Space Heater
2 sources1 derived$95.16as of Aug 1

The Vornado AVH10 is the best space heater you can buy for around $100. TechGearLab named it their top pick, praising how the signature Vortex circulation pushes 1500W of heat evenly around a whole room instead of just at whoever is in front of it. Auto Climate Control holds your set temperature, and it carries every safety feature you want: cool-touch case, tip-over protection, and auto shutoff. It runs quiet and efficient; the only catch is a price sitting right at the budget ceiling.

Strengths
  • — TechGearLab's top space-heater pick; Vortex air circulation heats a whole room evenly
  • — Full suite of safety features: cool-touch case, tip-over protection, auto shutoff
  • — Auto Climate Control holds your set temperature and saves energy
Watch-outs
  • — At about $100 it sits at the top of the under-$100 budget
  • — Fan is not the fastest, so drafty rooms take a while to catch up
  • — Some owners want a more durable power button

How they stack up

Dreo Atom One Space Heater

The quietest and most personal heater here, quieter than the Vornado AVH10 and Lasko 755320 and better suited to a desk than either. It is pricier than the bare-bones Amazon Basics 1500W but adds oscillation, a remote, and a full safety suite the Amazon Basics lacks.

Vornado AVH10 Whole Room Space Heater

The best whole-room heater here, circulating heat more evenly than the tower-style Lasko 755320 or the tabletop Lasko Ellipse CD12950, and far more than the personal Dreo Atom One or the Amazon Basics 1500W. It costs the most of the group but earns it with Vornado's circulation and Auto Climate Control.
