A large bedroom asks for two things that pull against each other: enough heat to reach the far corners, and quiet, dark operation for sleep. The best picks combine wide oscillation or infrared heat with low noise, dimmable displays, thermostats and timers.
We compared heaters by rated coverage, noise, light, controls and safety using manufacturer specifications and owner feedback. For scored tests see our space heater for bedroom for large room reviews; our Editorial Policy explains our process.
