Cadet F Series 72 In. Electric Baseboard Heater (6F1500-1W)
This 72-inch Cadet baseboard heater is rated for 1500 watts at 120 volts, providing continuous radiant/convection heat suitable for larger rooms or spaces that require steady warmth. The manufacturer notes that the heater “transmits heat continuously,” making it a choice for zones where uninterrupted output is desired.
Features listed by the manufacturer include continuous heat transmission and standard white finish. The unit is intended for hardwired installation and is constructed to meet common baseboard heater form factors. Because it is a full-length 72″ unit, it distributes heat over a longer wall run, reducing heat concentration in one spot.
Installation considerations: requires proper 120V branch circuit capacity and appropriate mounting clearances. This model is commonly paired with a compatible wall thermostat or built-in heater thermostat for temperature control.
Cadet F Series 36″ Electric Baseboard Heater (3F750-1W)

The 36-inch Cadet baseboard heater provides 750 watts at 120 volts, suitable for small rooms, bathrooms, or targeted zone heating. Manufacturer features emphasize a steel construction—25 gauge for the heater body and a 20 gauge junction box with ground—along with powder coat finish for durability.
Compatibility: this model requires a thermostat for temperature regulation. The product’s all-metal construction and factory finish offer a balance of durability and standard fit for renovation or new installation projects.
Because it’s a lower-watt model, it is useful for maintaining moderate comfort levels without overloading typical 120V circuits. Expect simpler wiring needs than larger units but still plan for a dedicated circuit depending on combined loads.
KING 4K1210BW K Series Baseboard Heater, 4′ / 1000W / 120V
The KING K Series 4-foot baseboard heater is specified for 1000 watts at 120 volts. It is a hard-wired unit (not a plug-in), designed with an aluminum ribbon fin element to enhance heat transfer and a full-length safety cutout for thermal protection.
Safety and build: the full-length safety cutout reduces the risk of overheating, and the element style supports efficient convective heating. This model is often chosen when a mid-range wattage and a reliable built-in safety feature are priorities.

Installation: requires hard-wiring to a 120V circuit and should be paired with an appropriate thermostat rated for the heater’s current draw for accurate control and energy management.
Elctrc Baseboard Heater, 60″ L, 120V (Dayton)
The Dayton labeled 60-inch baseboard heater is a standard electric lineup item for 120V installations. Manufacturer details emphasize it as part of “Electric Heaters and Accessories” with U.S. manufacturing noted for certain components or assembly.
Attributes: practical mid-length for medium to large rooms depending on wattage. The listing identifies it as a general-purpose electric baseboard heater suited for typical residential installations. As with other baseboards, expect hard-wired connection and necessary clearances to combustibles.
Consider this for projects emphasizing U.S. manufacturing or where a 60-inch length matches the available wall space and heat load calculations.
Mysa Smart Thermostat LITE For Electric Baseboard Heaters
The Mysa Smart Thermostat LITE is a smart control designed for high/line voltage electric heating systems, including 120–240V baseboard heaters. It provides Wi‑Fi connectivity, app-based scheduling, and integration with voice assistants such as HomeKit, Alexa, and Google Home.
Key technical note: Mysa requires proper wiring — it needs at least four wires including a neutral or a second live wire and does not support two-wire installations or low-voltage systems. The manufacturer warns buyers to confirm wiring compatibility prior to purchase.
Benefits: remote control with a free app, programmable schedules, and energy-saving features that can reduce electricity use through optimized setpoints. This thermostat pairs with 120V baseboard heaters to provide precise control and convenience.
Buying Guide: How To Choose The Right 120V Baseboard Heater
Selecting a baseboard heater depends on room size, circuit capacity, desired control method and installation constraints. Below are practical factors to guide a purchase.
Match Wattage To Room Size
- Calculate Heat Load: A common rule-of-thumb is 10 watts per square foot for typical insulated rooms. For colder climates or poorly insulated rooms, increase the wattage per square foot.
- Available Wattages: 750W (small rooms), 1000W–1500W (medium to large rooms). Choose units or combined lengths to reach required wattage without exceeding 120V circuit capacity.
Length And Placement Considerations
- Longer Units Spread Heat: A 72″ heater distributes heat over more wall area and can reduce hot spots compared with shorter, higher-watt units.
- Wall Space: Measure wall runs and clearance for furniture and curtains. Baseboards need unobstructed airflow for effective convection.
Wiring And Circuit Requirements
- Dedicated Circuit: Many baseboard heaters require a dedicated 120V circuit, especially at higher wattages. Verify breaker and wire gauge capacity.
- Hard-Wired vs Plug-In: Most in-line models (like the listed units) are hard-wired. KING and Cadet units are designed for hard-wiring, not plug-in.
Thermostat Compatibility And Control
- Built-In vs External Thermostats: Some baseboard models accept built-in thermostats; others require standalone wall thermostats.
- Smart Thermostats: If remote control or scheduling is important, choose a smart thermostat compatible with line-voltage heating (e.g., Mysa). Confirm wiring compatibility (some smart units need four wires and a neutral).
- Two-Wire Systems: Many smart thermostats do not work with two-wire installations—verify before purchase.
Safety Features And Build Quality
- Overheat Cutouts: Look for full-length safety cutouts or thermal protection to reduce risk of overheating.
- Material And Finish: Steel housings with powder coat finishes are common for durability; element design (aluminum ribbon fin vs tubular) affects heat transfer efficiency.
Installation And Maintenance
- Mounting & Clearance: Follow manufacturer specifications for wall mounting, clearance to floors, and distance from drapes or furniture.
- Wiring Access: Confirm the unit’s junction box size and ground provision to match local electrical codes.
- Serviceability: Choose models with accessible components for maintenance and with available replacement parts if long-term serviceability matters.
Comparison Perspectives To Consider
- Energy Use vs Comfort: Higher wattage heats faster but consumes more energy; pairing heaters with programmable thermostats or smart controls can reduce runtime and costs.
- Room Function: Bedrooms often benefit from thermostats with fine control and schedules; bathrooms may require shorter units placed near water sources with appropriate protection; living spaces can prioritize even distribution with longer units.
- Upfront Cost vs Long-Term Savings: Smart thermostats add upfront cost but can lower energy bills via schedules and remote control. Hardware quality influences lifespan and replacement frequency.
Practical Checklist Before Buying
- Measure room square footage and wall length available for heater mounting.
- Determine required wattage and confirm your breaker/wiring supports cumulative load.
- Decide on thermostat type: mechanical, built-in, or smart wall thermostat (confirm wiring).
- Verify product safety features and manufacturer installation instructions.
- Check compatibility notes for smart thermostats (e.g., Mysa) regarding wire count and voltage.
Using this guide, match your room’s heat load to the appropriate unit length and wattage, choose compatible controls, and follow installation best practices to ensure safe, effective heating with 120V baseboard systems.
