More Details on Our Top Picks

  1. Amazon Smart Plug – Works with Alexa, Easy Setup, Voice Control

    Amazon Smart Plug - Works with Alexa, Easy Setup, Voice Control

    Best Overall for Alexa-Only Users

    View on Amazon

    This Amazon Smart Plug stands out as the best choice for users committed to Alexa, thanks to its seamless integration and straightforward setup. Compared with the Kasa Smart Plug Ultra Mini, it offers reliable voice control and routines tailored for Alexa lovers, though it restricts you to a single ecosystem. Its compact size ensures it doesn’t block the second outlet, making it practical for everyday use. The automatic reconnection after outages boosts reliability, but it only supports 2.4 GHz networks and lacks compatibility with other voice assistants. If your smart home revolves primarily around Alexa, this plug delivers a smooth experience.

    Pros:
    • Easy setup with Alexa and Alexa app
    • Compact size preserves second outlet
    • Supports routines and scheduling for automation
    • Reliable connection with automatic reconnection
    Cons:
    • Limited to 2.4 GHz Wi-Fi networks
    • No support for other voice assistants

    Best for: Alexa-centric households seeking straightforward voice control and automation.

    Not ideal for: Users with Google Assistant or multi-platform setups, as it only supports Alexa.

    • Size:3.2” x 1.5” x 2.2” (80 mm x 38 mm x 57 mm)
    • Weight:3.1 oz. (87 grams)
    • Electrical Ratings:Input: 120VAC, 60Hz, 15A Max; Output: 15A Max

    Our verdict

  2. Kasa Smart Plug Ultra Mini 15A, EP10, Wi-Fi Outlet

    Kasa Smart Plug Ultra Mini 15A, EP10, Wi-Fi Outlet

    Best for Google Assistant and Multi-Platform Users

    View on Amazon

    This Kasa Ultra Mini excels in supporting both Alexa and Google Assistant, making it a flexible choice for homes with multiple voice ecosystems. Unlike the Amazon Smart Plug, its broader compatibility suits households with diverse smart setups. Its small footprint fits into tight outlets, but the 15A maximum current might limit larger heaters. Setup is straightforward through the Kasa app, and remote control plus scheduling enhance convenience. However, it requires a 2.4 GHz Wi-Fi network and doesn’t support energy monitoring features, which some users might find limiting. If you want a compact, versatile smart plug that works across platforms, this is a reliable pick.

    Pros:
    • Supports both Alexa and Google Assistant
    • Easy to set up with Kasa app
    • Compact design fits into tight outlets
    • Remote control and scheduling available
    Cons:
    • Limited to 15A maximum load
    • Requires 2.4 GHz Wi-Fi network

    Best for: Smart home owners using both Alexa and Google Assistant seeking versatility and easy control.

    Not ideal for: Those with high-current appliances exceeding 15A or seeking energy monitoring features.

    • Current:15A
    • Connectivity:Wi-Fi 2.4GHz
    • Compatibility:Alexa, Google Assistant
    • Certification:UL
    Our verdict
    “Best suited for users needing a compact, multi-platform compatible smart plug for heaters and appliances.”
  3. Amazon Basics Smart Plug, 4-Pack, Works with Alexa, Voice and App Control, Schedule, Compact Design, 2.4 GHz Wi-Fi, No Hub Required

    Amazon Basics Smart Plug, 4-Pack, Works with Alexa, Voice and App Control, Schedule, Compact Design, 2.4 GHz Wi-Fi, No Hub Required

    Best for Budget-Conscious Multi-Outlet Control

    View on Amazon

    This Amazon Basics 4-pack offers excellent value for those who need multiple smart plugs, especially for controlling heaters across different rooms. Its compatibility with Alexa makes it straightforward for Alexa users, but it doesn’t support other voice assistants, unlike the Kasa options. The compact design is a plus, allowing multiple outlets without blocking each other, but it lacks advanced features like energy monitoring. Setup is simple, and remote control plus scheduling are built-in, yet the absence of energy tracking means it can’t help monitor power consumption. If you want multiple affordable Alexa-compatible plugs, this pack provides good coverage at a lower price point.

    Pros:
    • Affordable 4-pack for multiple devices
    • Easy setup with Alexa
    • Compact design leaves other outlets free
    • Supports scheduling and remote control
    Cons:
    • Limited to Alexa compatibility
    • No energy monitoring features

    Best for: Budget-conscious households needing several smart plugs for different heaters or appliances.

    Not ideal for: Users seeking multi-platform support or energy monitoring capabilities.

    • Connectivity:2.4 GHz Wi-Fi
    • Number of Plugs:4
    • Compatibility:Works with Alexa
    • Design:Compact
    Our verdict
    “Best for families looking to control multiple heaters on a budget with Alexa only.”
  4. Amazon Basics Smart Plug with Timer Function, Voice Control, WiFi 2.4 GHz, APP Control, Schedule, Works with Alexa, No Hub Required, White

    Amazon Basics Smart Plug with Timer Function, Voice Control, WiFi 2.4 GHz, APP Control, Schedule, Works with Alexa, No Hub Required, White

    Best for Timer-Oriented Control and Alexa Users

    View on Amazon

    This Amazon Basics plug with timer functionality offers precise scheduling, making it ideal for controlling heaters that need timed operation. Its compatibility with Alexa simplifies setup, and the compact design fits into most outlets without obstructing neighboring sockets. Compared to the standard Amazon Basics plug, this version adds timer features, but it shares the same limitations—no support for other voice platforms and limited power details. The focus on scheduled control makes it suitable for budget-conscious users who prioritize timing over energy monitoring. However, the lack of detailed specs might concern those wanting to know power thresholds for larger heaters. If timed operation with Alexa control is your priority, this plug offers a straightforward solution.

    Pros:
    • Easy setup with Alexa
    • Timer and schedule features for precise control
    • Compact size fits standard outlets
    • Remote control via app
    Cons:
    • Works only with Alexa
    • Limited power and energy info provided

    Best for: Users who need precise scheduling for heaters and are committed to Alexa only.

    Not ideal for: Those wanting multi-platform voice support or detailed power metrics.

    • WiFi Frequency:2.4 GHz
    • Control:App and voice control
    • Compatibility:Alexa only
    • Features:Timer and schedule
    Our verdict
    “Perfect for Alexa users who want scheduled heater operation without complexity.”
  5. Kasa Smart Plug HS103P2 2-Pack

    Kasa Smart Plug HS103P2 2-Pack

    Best for Dual Control and Brand Trust

    View on Amazon

    The Kasa HS103P2 2-pack offers reliable remote control and voice compatibility with both Alexa and Google Assistant, making it a flexible option for controlling multiple heaters or appliances. Its straightforward setup and UL safety certification add confidence for everyday use. Compared with the Amazon Smart Plug, it supports both major voice platforms and maintains a similar compact footprint. However, its maximum load of 15A limits larger heaters, and it requires a 2.4 GHz Wi-Fi connection. This pack is excellent for users who want multiple plugs from a trusted brand, but it doesn’t include advanced energy monitoring or multi-user controls. If you need a dependable, multi-device setup, this 2-pack fits the bill nicely.

    Pros:
    • Supports Alexa and Google Assistant
    • Easy to set up and use
    • UL safety certified
    • Supports remote control and scheduling
    Cons:
    • Limited to 15A maximum load
    • Requires 2.4 GHz Wi-Fi

    Best for: Homeowners seeking multiple, trusted-brand smart plugs compatible with both Alexa and Google Assistant.

    Not ideal for: Large appliances exceeding 15A or users wanting detailed energy consumption data.

    • Voltage:120V
    • Amperage:15A
    • Plug Type:Type B
    • Number of Wires:3
    • Material:Plastic
    • Dimensions:1.6″D x 2.6″W x 1.5″H
    Our verdict

  6. Govee Smart Plug, WiFi Outlet Compatible with Alexa & Google Assistant, 4 pcs

    Govee Smart Plug, WiFi Outlet Compatible with Alexa & Google Assistant, 4 pcs

    Best Value Multi-Pack for Basic Home Automation

    View on Amazon

    This set of four Govee smart plugs stands out for offering a cost-effective way to control multiple heaters or appliances remotely. Unlike the Kasa Mini, which excels in compactness for single outlets, Govee’s plugs support both WiFi and Bluetooth, providing flexible connectivity options. While they include scheduling and group control, they are limited to 2.4 GHz WiFi, which might be a drawback for homes with 5G networks. The plugs are easy to set up via the app and support voice commands with Alexa and Google Assistant, making them suitable for users wanting simple automation without high power demands. The main tradeoff is the lack of 5G WiFi support and a slightly bulkier form factor compared to ultra-mini options. Overall, this pack offers good value for those needing multiple outlets for basic heater control in a standard WiFi environment.

    Pros:
    • Supports voice control with Alexa and Google Assistant
    • Includes scheduling and group control features
    • Compact design saves space and fits various outlets
    • ETL and FCC certified for safety
    Cons:
    • Does not support 5G WiFi networks
    • Limited to 2.4 GHz WiFi only

    Best for: Budget-conscious homeowners who want to control multiple heaters remotely and can operate on 2.4 GHz WiFi networks.

    Not ideal for: Users with 5G WiFi or high-power appliances, since it doesn’t support 5G networks or higher than 11A current.

    • Voltage:120 volts
    • Connector Type:Plug-in
    • Number of Poles:2
    • Amperage:11 A
    • Supports Bluetooth:Yes
    • Supports WiFi:Yes
    • WiFi Frequency:2.4G
    Our verdict
    “This multi-pack suits budget-focused users seeking reliable remote control for multiple heaters on standard WiFi networks.”
  7. Kasa Smart Plug HS103P4, Wi-Fi Outlet, Alexa & Google Compatible, 15 Amp, 4-Pack

    Kasa Smart Plug HS103P4, Wi-Fi Outlet, Alexa & Google Compatible, 15 Amp, 4-Pack

    Best for Easy Setup and Reliable Voice Control

    View on Amazon

    The Kasa HS103P4 is a dependable choice for those who prioritize straightforward setup and consistent performance. Compared to Govee, which offers a lower amperage, the Kasa supports a 15A load, making it more suitable for heavier heaters. Its UL certification adds peace of mind regarding safety, and the app-based scheduling and timers enhance automation capabilities. However, like Govee, it operates solely on 2.4 GHz WiFi, which could be limiting in some households. The push-button switch provides manual control, but it’s less compact than ultra-mini plugs like the Kasa EP10P2. This pick makes the most sense for users who want a trusted brand with straightforward functionality and higher current capacity.

    Pros:
    • Easy to set up and control remotely via smartphone or voice
    • Compatible with Alexa and Google Assistant
    • Supports scheduling and timers for automation
    • UL certified for safety
    Cons:
    • Requires 2.4 GHz WiFi network
    • Limited to 15A current, not suitable for high-power devices

    Best for: Homeowners seeking a reliable, easy-to-setup smart plug for medium-power heaters and appliances with minimal fuss.

    Not ideal for: Tech-savvy users with 5G networks or those requiring ultra-compact outlets, as it’s bulkier than mini models and limited to 2.4 GHz WiFi.

    • Operation Mode:automatic
    • Current Rating:15 A
    • Operating Voltage:120 volts
    • Control Method:Voice
    • Connectivity Protocol:Wi-Fi
    • Wattage:1800 watts
    Our verdict
    “This plug is ideal for users wanting a straightforward, high-capacity WiFi outlet with trusted safety features.”
  8. Kasa Smart Plug Ultra Mini 15A EP10P2 Wi-Fi Outlet

    Kasa Smart Plug Ultra Mini 15A EP10P2 Wi-Fi Outlet

    Best Compact Design for Limited Space

    View on Amazon

    The Kasa Mini EP10P2 offers a sleek, space-saving design that doesn’t block adjacent outlets, making it perfect for tight spaces. It supports Alexa, Google Assistant, and SmartThings, providing broad compatibility for automation. Unlike bulkier plugs, its small size minimizes clutter, but it still supports a 15A load, suitable for most heaters. Setup is straightforward via the Kasa app, with scheduling and timers to automate your devices. However, it relies solely on 2.4 GHz WiFi, similar to other options, limiting use in dual-band networks. This makes it ideal for users who want a discreet, reliable smart plug that won’t obstruct other outlets, but not for those needing 5G support or higher wattage capacity.

    Pros:
    • Ultra-compact design fits in tight spaces
    • Easy setup via Kasa app and voice control
    • Supports scheduling, timers, and away mode
    • Broad compatibility with Alexa, Google, and SmartThings
    Cons:
    • Requires 2.4 GHz WiFi network
    • Limited to 15A max load, not for high-power devices

    Best for: Users with limited outlet space seeking a compact, easy-to-control smart plug for moderate heaters.

    Not ideal for: Those with high-power appliances exceeding 15A or who require 5G WiFi compatibility, as it’s limited to 2.4 GHz networks.

    • Max Load:15A
    • Connectivity:Wi-Fi 2.4GHz
    • Compatibility:Alexa, Google Assistant, SmartThings
    • Certifications:UL, RoHS, FCC, IC
    Our verdict
    “This mini plug is best for space-constrained environments where reliable, basic automation is needed.”
  9. Kasa Outdoor Smart Plug KP401

    Kasa Outdoor Smart Plug KP401

    Best Weather-Resistant Outdoor Control

    View on Amazon

    The Kasa KP401 is designed for outdoor use, with an IP64 rating for weather resistance and a Wi-Fi range reaching up to 300 feet. This makes it well-suited for controlling outdoor heaters, landscape lighting, or pool equipment. It supports Alexa and Google Assistant, with scheduling and timers for automation. Compared to indoor plugs like the HS103P4, its weatherproof build and extended Wi-Fi range stand out, but it’s limited to 15A capacity and relies on 2.4 GHz WiFi. The absence of a physical switch might be a concern for manual control in outdoor settings. Overall, this plug is perfect for outdoor spaces that require reliable, remote control of heaters or other outdoor devices, but not for high-power outdoor appliances exceeding 15A.

    Pros:
    • Weather-resistant IP64 rating for outdoor use
    • Wi-Fi range up to 300 feet for outdoor control
    • Supports voice control with Alexa and Google
    • Easy setup with scheduling features
    Cons:
    • Requires 2.4 GHz WiFi network
    • Limited to 15A capacity
    • No physical manual switch

    Best for: Homeowners needing a weatherproof outdoor outlet for controlling outdoor heaters, pool pumps, or landscape lights over long distances.

    Not ideal for: Indoor users or high-power outdoor devices over 15A, as it’s limited to 15A and designed specifically for outdoor environments.

    • Connector Type:Plug In
    • Product Grade:Residential
    • Amperage:15 A
    • Material Type:Polycarbonate (PC)
    Our verdict
    “Ideal for outdoor spaces where weather resistance and long-range WiFi control are priorities for moderate outdoor heaters.”
  10. DIGITEN Wireless Thermostat Outlet 1800W for Space Heaters, Fans, AC

    DIGITEN Wireless Thermostat Outlet 1800W for Space Heaters, Fans, AC

    Best for Precise Temperature Control and Safety

    View on Amazon

    The DIGITEN Wireless Thermostat Outlet excels for users seeking precise temperature management of their space heaters. It offers a maximum load of 1800W, which is suitable for most household heaters and fans, unlike the other plugs that are limited to 15A. Its remote sensor and large LCD display provide easy, manual, and remote control of temperature settings, making it more versatile than typical smart plugs. While setup is straightforward, it involves pairing the remote sensor, which adds complexity compared to simple WiFi outlets like Kasa or Govee. It’s best suited for users who want more granular control over their heating devices but are okay with a dedicated device rather than a standard smart plug.

    Pros:
    • Large LCD with backlight for easy operation
    • Remote sensor for precise temperature control
    • Safety features to prevent circuit overheating
    • Versatile for heating, cooling, and outdoor use
    Cons:
    • Remote batteries not included
    • Requires setup of remote sensor
    • Limited to 1800W max load

    Best for: Homeowners who need accurate temperature regulation for space heaters and are willing to handle remote sensor setup.

    Not ideal for: Those seeking simple, app-based control without remote sensors or users with high-power devices exceeding 1800W.

    • Maximum Load:1800W
    • Input/Output Socket:Separate
    • Display:Large LCD with backlight
    • Certifications:FCC
    Our verdict
    “This thermostat outlet is well-suited for users wanting precise temperature control with safety features, accepting the extra setup effort.”

Factors to Consider When Choosing Smart Plug For Heaters

Choosing the right smart plug for heaters involves more than just compatibility. You need to consider power capacity, safety features, ease of installation, and how well it integrates with your existing smart home ecosystem. Making an informed decision ensures your heater operates safely and conveniently, without risking electrical issues or compatibility headaches.

Power Capacity and Wattage Limits

Heaters typically draw more power than standard devices, so verifying the wattage limit of your smart plug is essential. Many plugs support up to 15 amps, but some smaller models or mini plugs might not handle high wattage safely. Overloading a smart plug can lead to electrical failures or fire hazards, so always match the plug’s capacity with your heater’s power requirements.

Compatibility with Voice Assistants and Apps

Most users prefer plugs that work seamlessly with Alexa, Google Assistant, or other smart home systems. Check whether the plug supports your preferred platform, and whether it requires a hub or works directly over Wi-Fi. Compatibility impacts ease of control—voice commands or app scheduling can significantly enhance convenience, especially for heaters used frequently or in remote locations.

Safety Features and Certifications

Look for plugs with safety certifications such as UL or ETL, especially when controlling high-wattage appliances like heaters. Features like surge protection, automatic shutoff in case of overheating, and durable construction add peace of mind. Skipping safety considerations can expose your home to electrical risks, so prioritize certified models that meet safety standards.

Size and Design

Compact, slim designs are preferable if you need to plug multiple devices into the same outlet or have tight space constraints. However, smaller plugs sometimes have reduced power handling or fewer features. Larger, more robust models may be easier to connect and support higher wattages but can block adjacent outlets. Weigh your space constraints against your power needs when choosing.

Ease of Setup and Use

Intuitive installation and straightforward app interfaces greatly improve user experience. Some models require complex configurations or frequent firmware updates, which can be frustrating. Choosing a plug with a simple setup process and clear instructions saves time and reduces the chance of errors, especially if you’re not tech-savvy.

Frequently Asked Questions

Can I use a smart plug for a high-wattage heater?

Yes, but only if the smart plug supports the heater’s wattage. Many standard plugs support up to 15 amps, which is sufficient for most space heaters, but always check the specific wattage limits. Using a plug with inadequate capacity could cause overheating or damage the device, so verify the maximum supported load before purchasing.

Is it safe to control my heater with a smart plug?

Controlling a heater via a certified smart plug is generally safe when the device is rated for the load and includes safety features like surge protection. However, it’s vital to ensure the plug has proper certifications and is installed correctly. Overcurrent or faulty devices can pose fire risks, so always choose quality models from reputable brands.

Do I need a hub for a smart plug for heaters?

Most modern smart plugs connect directly to your Wi-Fi network and do not require a hub. This simplifies installation and reduces additional costs. However, if you already have a smart home hub that supports certain protocols, some plugs might integrate more smoothly into your existing setup. Check the product specifications to confirm whether a hub is necessary.

Can I schedule my heater to turn on and off automatically?

Yes, most smart plugs include scheduling features via their apps, allowing you to set specific times for the heater to operate. This helps save energy and maintains comfort without manual intervention. Keep in mind that scheduling accuracy depends on the app’s reliability and your Wi-Fi connection.

What should I consider when choosing a smart plug for outdoor heaters?

For outdoor heaters, look for weatherproof, waterproof, or outdoor-rated smart plugs. These are designed to withstand moisture, temperature fluctuations, and UV exposure. Additionally, verify that the maximum wattage and current ratings are suitable for outdoor use, and consider models with safety features like circuit protection. Proper installation and coverage prevent electrical hazards in outdoor environments.

Conclusion

The best overall smart plug for heaters is the Amazon Smart Plug thanks to its reliable performance and seamless Alexa integration, making it ideal for most users. Budget-conscious buyers will appreciate the Amazon Basics Smart Plug, which offers solid core functionality at a low price. For those seeking a premium experience with advanced features, the Kasa Smart Plug HS103P4 provides excellent compatibility and durability. Beginners or less tech-savvy users should opt for models with simple setup processes, like the Kasa Ultra Mini. Meanwhile, if outdoor use or high wattage is required, specialized models like the Kasa Outdoor Smart Plug or DigitEN Wireless Thermostat Outlet are better suited. This tailored approach ensures you select the right smart plug based on your specific heating control needs.
