This Cadet Com-Pak model is a complete in-wall unit with an integrated thermostat designed for single-room supplemental heating. The unit is rated at 1500 watts, 120 volts, and lists a heating capacity described as 5120 BTU. It installs directly into a wall cavity and includes a grille for finished appearance.

Key functional notes from the manufacturer include the built-in thermostat for simple temperature control and a fan-forced element to distribute heat quickly. The design fits common wall cutouts and is offered in white to match interior trims. Safety features are factory-installed to interrupt heat if temperatures exceed normal values.

Cadet Com-Pak CSC202TW 2000/1500W

Check Price on Amazon

The CSC202TW expands capability with multi-voltage support (208/240V or 240/208V) and dual wattage ratings depending on wiring. Cadet lists fast heating performance and a fan to circulate warmth, recommending these models for rooms up to a specific square footage when used as a primary supplemental source.

Highlighted features include fast heating coil element and a quiet fan that spreads heat more evenly than a purely radiant product. The unit is noted for safety cutoff protection if operating temperatures are exceeded. Installation guidance mentions suitability for ceiling installation on lower wattage models and altitude recommendations for best performance.

Broan-NuTone 9815WH Wall Heater

Check Price on Amazon

The Broan-NuTone 9815WH is positioned as a large-capacity wall heater with a front-mounted adjustable thermostat and a design focused on quiet operation. It ships factory-wired for 120V/1500W but can be converted for 240V in some installations, expanding flexibility for different electrical setups.

Designed for energy-saving supplementary heating, the model includes a permanently lubricated motor and simple front access to the thermostat for easy temperature adjustments. The grille styling aims for a low-profile appearance while providing even heat distribution through angled louvers.

Heat Storm 1500 Watt In-Wall WiFi

Check Price on Amazon

The Heat Storm in-wall model adds WiFi connectivity to an in-wall electric heater, pairing a digital thermostat with remote app control and scheduling. It offers selectable 1500W or 750W output, enabling lower-power operation when full output isn’t needed.

Notable specs include a digital thermostat with adjustable LED brightness and the ability to set custom heat schedules remotely. This model brings smart control features to an in-wall platform, useful for users who want app-based temperature management and remote access to heat settings.

Mysa Smart Thermostat For Electric Heaters

Check Price on Amazon

Mysa is a dedicated smart thermostat for high/line-voltage electric heating, including baseboards, convectors, and fan-forced wall heaters. It supports 120–240V systems and load limits up to 1900W at 120V or 3800W at 240V, while requiring a compatible four-wire electrical box.

Key features include Wi‑Fi connectivity, HomeKit/Alexa/Google integration, and a dedicated app for scheduling, energy tracking, and remote control. The device emphasizes compatibility checks—important because older two-wire baseboard systems are not supported. Mysa also offers adaptive display and brightness features for user convenience.

Buying Guide: Choosing An In-Wall Electric Heater With Thermostat

1. Determine Heating Capacity And Room Size

Match heater output to the room. As a rule of thumb, 1,000–1,500 watts suits small to medium rooms (80–200 sq ft). Larger rooms may need higher wattage or multiple units. Manufacturers often list BTU equivalents or suggested square footage—use these as starting points.

2. Voltage And Electrical Compatibility

Confirm your home wiring before buying. Some in-wall models are 120V only, while others support 208/240V. High-voltage smart thermostats require specific wiring configurations (often four wires including a neutral). Installing incompatible voltage can damage equipment and violate code.

3. Built-In Thermostat vs Dedicated Smart Thermostat

Built-in mechanical or digital thermostats provide simple local control and ease of installation. Smart thermostats (Mysa, meross) add scheduling, remote access, and voice assistants but require electrical compatibility and Wi‑Fi. Choose based on whether you prioritize local simplicity or advanced control features.

4. Fan-Forced vs Radiant Heat Distribution

Fan-forced in-wall heaters circulate warm air quickly and can heat evenly across a room. Radiant or convector units rely on natural convection and may feel slower. If noise is a concern, look for models with quiet fan motors or low-noise ratings.

5. Installation Considerations

In-wall units require a proper cavity, adherence to clearances, and electrical junction box access. Some units are convertible for ceiling or recessed installations—verify manufacturer instructions. When in doubt, consult a licensed electrician for planning and installation to meet local code.

6. Safety Features

Look for overheat protection, automatic shutoff, and thermal cut-outs. Fan-forced heaters should have safeguards if airflow is obstructed. UL or ETL listings and clear cooling zone instructions indicate safety-focused design.

7. Controls And User Interface

Consider stove-style knobs vs digital displays. Digital thermostats and WiFi-equipped models offer precise temperature control, scheduling, and remote operation. If elderly users or renters need simplicity, front-mounted mechanical thermostats are easy to operate.

8. Smart Home Integration

If you use HomeKit, Alexa, or Google Home, ensure the thermostat or heater lists explicit compatibility. Some smart thermostats support geofencing, adaptive schedules, or energy reports. Confirm the app ecosystem and required network security setup before purchase.

9. Energy Efficiency And Cost To Operate

Electric resistance heating is typically less efficient than heat pump systems, so target use as supplemental heat or for rooms where ducted heating isn’t available. Smart thermostats can reduce runtime through scheduling, helping lower operating hours and energy consumption.

10. Noise, Aesthetics, And Finish

Grille styling, louvers, and unit depth affect appearance and integration with interior decor. Fan speed and motor type determine noise levels—check manufacturer descriptions for “quiet” or “silent motor” claims and user reviews for real-world feedback.

11. Warranty And Replacement Parts

Verify warranty length and availability of replacement grilles, thermostats, or elements. Units from established HVAC brands frequently have better parts availability and documented installation support.

12. Multiple Comparison Perspectives

• Best For Smart Control: Choose WiFi-enabled heaters or pair with a compatible smart thermostat (Mysa, meross).
• Best For Simplicity: Factory units with front-mounted mechanical thermostats (Cadet, Broan).
• Best For Flexibility: Models that support 120/240V or convertible wiring accommodate more home setups.
• Best For Quiet Operation: Seek units with low-noise fan motors or passive convection options.

Before purchase, gather your room dimensions, verify electrical service and box wiring, and decide whether local thermostat control or smart scheduling is essential. Consulting an electrician can clarify voltage, wiring needs, and code compliance for a safe installation.
