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 DeLonghi Dragon Digital Oil Filled Radiator Heater is a solid choice for heating small to medium indoor spaces such as bedrooms or home offices. It uses 1500 watts to deliver gentle, radiant heat that warms the room quietly without a fan, which helps avoid blowing dust or allergens around. This makes it a good option if you want a more allergy-friendly environment. One of its standout features is the digital control panel with a clear LED display and a 24-hour programmable timer, allowing you to customize heating times easily.

The ECO Plus function helps save energy by adjusting power and temperature efficiently, which may reduce your electric bill compared to less advanced heaters. Safety is well-covered with built-in features like a child lock, automatic shutoff if it overheats, and an anti-freeze setting that kicks in when temperatures drop close to freezing. The heater is also portable for its size, thanks to ergonomic handles and smart wheels that move smoothly between rooms without assembly.

It weighs about 26.6 pounds, so it’s not the lightest heater, and it only offers one heat setting, which might limit temperature control flexibility. Also, it’s designed mainly for indoor use and smaller spaces, so it may not be powerful enough for large rooms or open areas. If you want a quiet, efficient heater with safety features and easy controls, this model fits well for everyday home use, especially during colder months.
