- Voltage/Wattage: 120 V, 1250 W (hard-wired).
- Element: Aluminum ribbon fin for heat transfer efficiency.
- Safety: Full-length thermal cutout for overheat protection.
Context For 24″ Buyers: This is a longer 5-foot model, but it illustrates characteristics of 120V baseboard heaters (element types, safety cutouts). If you require a 24″ 120V unit, confirm wattage scaling and thermostat compatibility; shorter lengths will reduce wattage proportionally.
Stamped Steel 24 inch Brown Baseboard Register
Overview: This stamped steel 24″ baseboard register is an accessory designed to cover floor openings up to 21″ x 2.5″. It includes a single-lever damper and a brown powder coat finish for rust protection.

Buying Guide: How To Choose A 24-Inch Baseboard Heater For 120 Volt Systems
1. Confirm Voltage Compatibility
- Always verify the heater is explicitly rated for 120 volt operation. Some compact 24″ models are made for 240/208 V and are not interchangeable with 120 V circuits.
2. Determine Required Wattage And Coverage
- Wattage determines heat output. As a rule of thumb, 10 watts per square foot is a starting point for basic heat load estimates. A 24” heater will have lower wattage than longer units; confirm the model’s wattage rating and match to room size and insulation.
3. Thermostat Type And Control
- For 120V heaters, choose a line-voltage thermostat rated for the heater’s amperage and wattage. Decide between built-in thermostats, wall-mounted manual thermostats, or electronic models with better accuracy.
4. Element Type And Safety Features
- Elements vary: aluminum ribbon fins, steel tubular elements, or serpentine elements. Look for thermal cutouts or full-length safety cutouts to prevent overheating.
5. Installation And Wiring
- Many baseboard heaters are hard-wired and require a dedicated circuit. Confirm whether the model is plug-in or hard-wired. For hard-wired installations, follow local electrical code or hire a licensed electrician.
6. Physical Size, Clearance, And Placement
- Measure the available wall length. A 24″ cabinet may suit small zones, but heat output scales with length. Ensure required clearances from furniture, curtains, and combustible materials are observed.
7. Aesthetics And Finish
- Color and finish (white, almond, brown) matter for visible installations. Registers and trim pieces can improve looks and protect openings.
8. Matching Accessories
- Order compatible registers, end caps, and thermostats designed for the heater series. For Cadet heaters, using Cadet-branded thermostats often simplifies fit and mounting.
9. Safety, Codes, And Ratings
- Ensure the heater has appropriate UL/ETL listings for residential use. Verify amperage ratings and whether single-pole or double-pole thermostats are required by code for your application.
10. Comparison Perspectives
- Performance vs. Size: Shorter units (24″) have lower wattage; compare expected heat output per foot across models.
- Voltage Flexibility: Some brands offer the same model in multiple voltages—confirm part numbers carefully.
- Built-In vs. Remote Thermostats: Built-in thermostats reduce wall wiring but limit placement; wall-mounted thermostats give centralized control for multiple heaters.
