Best if you want more heater than a tiny desktop unit while staying under $40.
Every electric space heater is capped at the same 1500W by standard household circuits, which means the actual heat output of a $25 heater and a $90 one isn't that different.
The best space heaters under $40 give up oscillation, digital displays, and remotes, not raw warmth, which makes them a legitimately good value for a single room or desk.
The Lasko 754200 desktop ceramic heater delivers an adjustable thermostat and overheat protection for around $25, making it the strongest overall value in this price tier.
The slightly larger Lasko CT16450 adds height and a bit more presence in a room for a few dollars more, staying just under the $40 mark depending on current pricing.
The Best Space Heaters Under $40 at a Glance
Best overall: Lasko 754200, an adjustable thermostat and overheat protection in a compact desktop unit for around $25.
Best step-up pick: Lasko CT16450, more height and presence for a small room, still under $40.
What You Give Up at This Price
No oscillation: every heater in this price tier heats in a fixed direction. You'll need to aim it at where you actually sit.
No remote or digital display: adjustments happen at the unit itself with a physical dial.
Louder fan noise: budget heaters use simpler, less refined fan motors than the brushless DC motors found in premium models like the Dreo Solaris 317.
What you don't give up: the core safety features. Overheat protection and tip-over safety switches are standard even at this price point, and the actual wattage output matches every heater in this category.
