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 Broan-NuTone 9815WH is a solid choice if you're looking for a supplemental electric wall heater for a small to medium room, covering about 150 square feet. It runs at 1500 watts, which is a common power level for this type of heater, providing reliable warmth without being oversized. Its built-in adjustable thermostat is user-friendly, letting you easily control the heat level right from the front. This model includes safety features like a fan-delay switch to warm up the element before the fan starts, and a thermal protection motor that shuts off if it overheats, adding peace of mind during use. Installation is straightforward since it's designed for indoor wall mounting and can work with either 120V or 240V power, giving some flexibility depending on your home’s wiring.

The heater operates quietly, which is great for bedrooms or quiet spaces where noise can be distracting. Its design is clean and modern with a white grille and subtle contours, so it blends well with most interiors without standing out. In terms of energy efficiency, while it uses a fixed 1500W output typical for wall heaters, it is intended as a supplemental heat source rather than a primary one, helping to save energy by heating smaller areas or rooms selectively.

One downside is that it doesn’t offer advanced features like programmable timers or smart controls, which some newer models have. Also, while it’s well-built with steel materials, it’s not designed for outdoor use. Its size is fairly compact but still noticeable on the wall, so placement is something to consider. If you want a dependable, easy-to-use wall heater that provides consistent supplemental heat with good safety protections and a quiet operation, the Broan-NuTone 9815WH is a dependable pick.

The Cadet Com-Pak Electric Wall Heater is a solid choice for those needing to quickly and efficiently heat up spaces up to 200 sq. ft. With its 2000/1500 wattage options and built-in adjustable thermostat, it offers suitable heating control. The heater's fan is designed to spread warmth quietly, which should appeal to users who prioritize a low-noise environment. Safety features, like automatic shut-off if temperatures exceed normal levels, enhance usability and peace of mind, making it safe for home use.

The compact design helps it blend seamlessly into walls, maximizing living space, and it comes as a complete unit including a wall can, heater, grill, and thermostat, simplifying installation. However, it's important to note that ceiling installation is only possible with models that are 1500 watts or less and that it works best at elevations below 10,000 feet. The high gloss enamel paint gives it a sleek look, and it is UL listed, ensuring compliance with safety standards.

Though efficient, the heater's energy use might be a concern for some, especially at the higher wattage setting. Installation is relatively straightforward but requires hard-wiring, which might necessitate professional help for some users. Lastly, while the unit is compact, the need for a cut-out in the wall can be a limitation for certain spaces.
