Whether you want to stay warm in a cold space or simply save on electricity, a space heater could be your solution. The nifty devices are an alternative to central heating that put the power of warmth right at your fingertips, whether you want to heat up a bedroom, bathroom, basement, garage, or patio.

Here are the 15 best space heaters, according to customer reviews.

Space heaters, which measure their power in watts, generate heat through a few different methods including oil, radiation, infrared light, or even ceramic conductors. For many shoppers, the type of heating element matters less than the look or power—luckily there are designs that account for both. Plus, the robust selection of space heaters also includes budget-friendly options, as well as wall-mounted picks to save space.

Below, we've rounded up the most affordable space heaters to use around your home (or office) to instantly warm your fingers and toes. The best part? They're all on Amazon.
