10 Best Electric Wall Heaters 2025 in the United States

The Dreo Smart Wall Heater is a solid option for those looking to efficiently heat a bedroom or small living space. With a robust 1500W power output and the ability to warm up to 215 sq. ft., it’s suitable as either a primary or supplementary heating source. One of its standout features is the 120° vertical oscillation, which helps distribute heat evenly throughout the room, making it more effective than traditional wall-mounted heaters.

An adjustable thermostat allows users to set temperatures between 41°F to 95°F with impressive 1°F accuracy, ensuring comfortable conditions tailored to personal preferences. The convenience of smart control through the Dreo app or voice commands via Alexa and Google Home enhances usability, promoting a seamless lifestyle.

For nighttime use, the heater operates with minimal noise, and its LED panel adjusts to low-light conditions, making it ideal for a bedroom setting. Installation is hassle-free, coming with all necessary accessories and a user-friendly guide, which is a great plus for those who are not handy. There are a few considerations. While it claims to be energy-efficient, actual savings can depend on usage and insulation of the room. Additionally, the heater is designed for indoor use only, which limits versatility for outdoor heating needs. Some users might find the size (4.72”D x 20.08”W x 13.39”H) bulky for smaller rooms, and it does require wall mounting, which may not appeal to everyone.

The Dreo Smart Wall Heater is well-equipped for heating indoor spaces efficiently and conveniently, particularly for those who appreciate smart home integration. Just keep in mind its specific heating capacity and installation requirements to determine if it's the right fit for your home.

The KING KB2407-1-B2-ECO is a powerful 7500-watt electric heater designed mainly for garages or similar indoor spaces, capable of heating up to 700 square feet. It operates on 240 volts and has a tower-like design, which is fairly compact at about 16.5 inches tall, making it suitable for floor mounting without taking up too much space. One of its notable features is the built-in thermostat paired with remote control, allowing you to easily adjust the temperature without physically touching the unit.

The heater also includes a fan delay function to safely dissipate heat, which adds a layer of safety and helps maintain consistent warmth. Additionally, the option for summer fan-only and timer modes allows for some flexibility beyond just heating, which can improve energy efficiency when full heating isn't needed. Installation is simplified by the universal wall or ceiling mounting bracket included, though it’s mainly marketed as a floor-mounted unit. Noise-wise, since it uses a fan, expect some operational sound, but it is generally not overly loud for a garage setting.

With a power draw of 31.25 amps, it requires a suitable electrical setup, which might need professional installation if your garage isn’t already equipped for high voltage. Also, while it has good safety features, it’s important to follow installation guidelines carefully to avoid any hazards. The heater’s design is practical rather than decorative, which fits well in a workspace but might not blend into living areas. This heater is a solid choice if you need reliable, high-output heating for a garage or workshop, offering useful control features and safety functions, but keep in mind the electrical requirements and typical fan noise.

The Dreo Smart Wall Heater is a solid choice if you're looking to heat a small to medium indoor space like a bedroom, office, or living room. With a 1500-watt PTC heating system, it delivers reliable warmth while running quietly at just 28 dB, so it won't disturb your peace. Its adjustable electronic thermostat and ECO mode help maintain a comfortable temperature efficiently, which can save energy over time.

The heater also offers great convenience through multiple controls—you can use the remote, the Dreo app, or even Alexa voice commands to adjust settings, including a 24-hour timer and display brightness. Installation is straightforward with the included wall-mount template and a fairly long power cord. Safety is well-covered with flame-retardant materials, overheat protection, and an IP24 waterproof rating, making it safe for typical indoor use. The heater’s size is fairly compact, fitting neatly on your wall without taking up floor space.

It’s best suited as a primary heat source for around 150 square feet or a supplement for larger areas up to 750 square feet—so if you have a big room or poor insulation, it might struggle to keep you fully warm. The 30° manual oscillation helps spread heat more evenly but is limited in range compared to some other models. If you want a smart, quiet, and easy-to-use wall heater with good safety features and moderate heating power, the Dreo hits the mark well.
