This Cadet F Series 36″ model is a wall-mounted, low-profile electric baseboard heater rated at 750 watts, 120 volts. The unit uses 25-gauge steel for the cabinet with a 20-gauge junction box and powder-coated finish for durability. It is an all-metal design intended for hard-wiring and requires a separate thermostat to control temperature.

Notable practical details include a grounded junction box and a design meant for permanent installation rather than plug-in use. The model is suitable where a slim, lower-wattage solution is needed for small rooms or supplemental heat. Installation considerations include wiring to an existing thermostat circuit or installing a new one wired to the heater.

The Cadet F Series 24″ baseboard heater is a compact 350-watt option available in 240/208 volt configurations. Built from steel with a white finish, this small unit is suited for tight zones, bathrooms, or hallways where limited wattage and a narrow housing are required. Its smaller footprint allows installation in spaces where longer units would be impractical.

The listing identifies the product material and power source as electric. Because it operates at higher voltage in this configuration, ensure compatibility with your existing wiring and thermostat controls. For supplemental heat or for modest-sized rooms, a 24-inch slim heater can provide targeted warmth without occupying significant baseboard space.

Buying Guide: How To Choose A Slim Baseboard Heater

Selecting a slim baseboard heater requires evaluating room size, electrical supply, safety features, and installation constraints. Below are the key considerations to compare models objectively.

Tips for Getting the Best HVAC Prices

  1. Prioritize Quality Over Cost
    The most critical factor in any HVAC project is the quality of the installation. Don’t compromise on contractor expertise just to save money.
  2. Check for Rebates
    Always research current rebates and incentives — they can significantly reduce your overall cost.
  3. Compare Multiple Quotes
    Request at least three estimates before making your choice. You can click here to get three free quotes from local professionals. These quotes include available rebates and tax credits and automatically exclude unqualified contractors.
  4. Negotiate Smartly
    Once you've chosen a contractor, use the proven strategies from our guide — How Homeowners Can Negotiate with HVAC Dealers — to get the best possible final price.

Heat Output And Room Size

  • Wattage vs Room Area: Higher wattage provides more heat. Typical guidance is 10 watts per square foot for average insulation—adjust as needed for ceiling height and windows.
  • Single-Room vs Supplemental: Use lower-watt models (300–800W) for small baths or hallways; 1000–1500W units are common for medium rooms.

Voltage And Installation Type

  • Hard-Wired vs Plug-In: Many baseboards, especially slim permanent models, require hard-wiring and professional installation. Confirm whether the unit is plug-in or requires electrical work.
  • Voltage Requirements: Models can be 120V, 208V, or 240V. Match heater voltage to your circuit and panel capacity.

Controls And Thermostats

  • Built-In Thermostats: Units with digital or adjustable thermostats allow direct control at the heater. These are useful if there is no central thermostat.
  • External Thermostat Compatibility: Some slim models require a separate wall thermostat. Verify compatibility and wiring needs before purchase.

Safety Features

  • Overheat Protection: Prevents excessive temperatures and reduces fire risk.
  • Tip-Over Switch: Relevant for freestanding units; less common on hard-wired baseboards but useful for portable slim models.
  • Stay-Cool Body: Reduces burn risk on external surfaces, important for homes with children or pets.

Construction And Durability

  • Material: Steel housings with powder-coat finishes resist rust and dents. Aluminum ribbon elements provide efficient heat transfer.
  • End Panels And Covers: Dent-proof end panels extend aesthetic life in high-traffic spaces. Separate front covers are available for refurbishment or style upgrades.

Noise And Comfort

  • Convection Quietness: Most slim baseboards use convection and are quiet compared to forced-air systems. If silence is crucial, look for listings that call out whisper-quiet operation.
  • Even Heat Distribution: Longer elements distribute heat more evenly; shorter slim units concentrate heat in a smaller zone.

Installation Constraints And Code

  • Clearance And Mounting: Check manufacturer recommendations for floor clearance, wall mounting, and distance from drapes or furniture.
  • Local Codes: Electrical codes determine permitted wiring methods. Hard-wired units may require a licensed electrician and proper circuit sizing.

Maintenance And Upgrades

  • Ease Of Cleaning: Slim, sealed housings reduce dust accumulation inside the element area. Removable covers simplify cleaning.
  • Cover Replacements: If appearance is a concern, aftermarket slip-on covers exist to refresh older units without replacing the heater core.

Comparison Perspectives

  • Performance: Compare watt-per-foot and listed element types (aluminum ribbon vs nichrome) to gauge efficiency and responsiveness.
  • Control Options: Digital thermostats provide tighter control and easier monitoring than simple two-stage switches.
  • Safety & Warranty: Inspect manufacturer safety features and warranty terms to assess long-term reliability and support.
