Most bedrooms do not need a full 1500W heater running all night. Once the room is warm, a 300–800W heater or a low-watt wall panel can hold the temperature while drawing a fraction of the power, especially with a thermostat or ECO mode.

We compared bedroom heaters by wattage options, thermostat and ECO control, noise and safety using manufacturer specifications and owner feedback. For scored tests see our space heater for bedroom energy efficient reviews; our Editorial Policy explains our process.
