10 Best Energy Efficient Space Heaters 2025 in the United States

The Lasko Oscillating Digital Ceramic Tower Heater is a solid choice for those looking to efficiently heat small to medium-sized rooms, such as bedrooms or home offices. With a heating capacity of 1500 watts, it provides enough warmth for various indoor settings. One of its key features is energy efficiency, which helps keep electricity bills manageable while still delivering reliable heat.

This heater includes two quiet heat settings and an adjustable thermostat, allowing users to customize their heating experience easily. The optional oscillation feature is particularly useful, as it helps distribute warm air evenly across the room, enhancing comfort. Safety is a priority with this heater, featuring built-in protections like overheat prevention and a cool touch exterior, ensuring safe use even after extended operation. Additionally, the fully assembled design allows for quick setup—just plug it in and you're good to go. The remote control adds convenience, enabling users to adjust settings from across the room.

Portability is another strong point, as it weighs only 7.29 pounds and has a built-in carry handle, making it easy to move between spaces. The programmable timer, which can be set from 1 to 8 hours, adds flexibility for users who want to manage heating times effectively. However, there are a couple of minor drawbacks to consider. While it is quiet for a space heater, some users may still notice noise from the fan, especially on higher settings. Also, its heating coverage is limited, so it may not be ideal for larger open spaces.

The Dreo Smart Wall Heater is designed for indoor spaces such as bedrooms, living rooms, or home offices, offering a heating capacity suitable for areas up to 200 sq. ft. as a main heater and up to 750 sq. ft. when used alongside other sources. Its 1500W electric power and 120° vertical oscillation help spread warmth evenly and quickly, which is a plus for efficient heating. Energy efficiency is supported by an adjustable thermostat and a digital display that allows precise temperature control from 41°F to 95°F, helping to avoid wasting heat.

The heater’s smart features, including remote control via the Dreo app and compatibility with Alexa and Google Home, add convenience and help manage energy use effectively. It also includes a 24-hour timer to schedule heating sessions, which can contribute to saving electricity. Safety-wise, the wall-mounted design keeps it out of the way, and the product includes a reusable filter and easy maintenance steps. Noise levels are low during operation, making it suitable for bedrooms where quiet is important.

Being a wall-mounted unit, it lacks portability compared to freestanding heaters, so it’s best if you want a fixed installation rather than moving the heater from room to room. Installation requires some effort, as it comes with a drilling guide, but once mounted, it blends well with modern home setups. This heater is a smart choice if you want energy-efficient, quiet, and evenly distributed heat with convenient app and voice controls, especially for smaller to medium-sized rooms, but less ideal if you need a portable option.

The Dyson Hot+Cool™ AM09 Jet Focus heater and fan is a versatile appliance suitable for those looking for both heating and cooling functions in one device. One of its main strengths is its Air Multiplier technology, which provides a smooth and uninterrupted airflow, making it efficient for both heating and cooling. The ceramic plates heat up quickly, which is beneficial for fast heating during cold weather. Additionally, the Jet Focus control allows you to switch between focused and diffused modes, giving you the flexibility to heat a specific area or the entire room based on your needs.

The sleep timer and remote control add convenience, allowing you to program the heater to turn off at set intervals and to control it easily from a distance. Smooth oscillation helps distribute airflow evenly across the room. Users may find the noise level to be a potential downside, as fan heaters can be louder than other types. Portability is decent due to its tower form factor, but it may not be as lightweight or compact as some other space heaters.

The Dyson Hot+Cool™ AM09 offers a blend of performance and convenience, making it ideal for users needing a year-round solution with both heating and cooling capabilities.
