KING 6K2412BW K Series Baseboard Heater, 6′
This KING K Series model is sized for larger runs with hard-wired 1500W at 277V capability. It uses an aluminum ribbon fin element for convective heat distribution and lists a full length safety cutout to reduce overheating risk. The unit is not a plug-in style and is intended for permanent wiring to a 277/240V circuit. For installations in commercial corridors or large rooms where a 277V supply is present, this model provides a high output option with standard raceway compatibility.
KING 2K2403BW K Series Baseboard Heater, 27″
This compact KING K Series 27″ unit is rated for 500-375W at 277-240V, making it suitable for small zones or supplemental heating on 277V feeds. The heater features an aluminum ribbon fin element and a full length safety cutout, plus a crushproof element design for durability during handling and installation. Its slim footprint fits tight wall spaces where lower wattage is required from a commercial 277V supply.
KING 2K2403A K Series Baseboard Heater, 27″ Almond

The KING 2K2403A shares the same electrical and safety features as the 2K2403BW but comes in an almond finish for different décor requirements. It includes the aluminum ribbon fin, full length safety cutout, and crushproof element. Rated for 500-375W on 277-240V, it is applicable where a slightly lower profile heater and color match are desired while still operating on a 277V-capable circuit.
Cadet F Series 36″ Electric Baseboard Heater (3F750W)
The Cadet F Series model is listed with multi-watt capability (750/563W) and supports 240/208V operation. It emphasizes easy installation with universal wiring and pre-punched knockouts. The unit uses convection heating to circulate warm air through the room. While not specified as 277V, the 240V rating is commonly used in commercial contexts; confirm compatibility with a facility’s 277V distribution before selecting this model or consult an electrician for suitable 277V alternatives or wiring adjustments.
Marley 2542NW 240V 2′ Baseboard Heater
The Marley 2542NW is a 2′ convection baseboard heater engineered for 240V circuits. It highlights rapid convection heating without forced airflow, which reduces dust circulation. The design includes a large wiring compartment, dual knockouts and an integrated cable clamp to facilitate wiring. As with other 240V devices, verify suitability for a 277V distribution or consult an electrician about transformer or wiring options for 277V systems.

Tips for Getting the Best HVAC Prices
- 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. - Check for Rebates
Always research current rebates and incentives — they can significantly reduce your overall cost. - 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. - 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.
Electrical Compatibility And Voltage
- Confirm Voltage: Only choose units explicitly rated for 277V or for a 277–240V range. Some products list 240V only; these may not be compatible without conversion.
- Hard-Wired vs Plug-In: Commercial 277V circuits commonly use hard‑wired units. Verify the product is designed for permanent wiring if required.
- Multi-Watt Models: Multi-watt or multi-tap models provide flexibility for different voltages; confirm the exact ratings on manufacturer documentation.
Heat Output And Room Sizing
- Wattage To Area: Calculate required watts per square foot for the space (typical guideline: 10–20 W/ft² depending on insulation and climate). Choose a model that meets the calculated load when combined with other heaters if necessary.
- Convection Characteristics: Aluminum ribbon fin elements heat quickly and distribute convective airflow evenly. Longer units provide more surface area and steadier output.
Safety And Durability
- Safety Cutouts: Full length safety cutouts reduce overheating risk and are valuable in commercial applications.
- Crushproof Elements: Look for crushproof or protected elements for shipping and installation durability.
- Wiring Compartment: Large access, knockouts and built‑in clamps simplify code-compliant terminations.
Installation And Maintenance
- Mounting And Size: Select lengths that fit wall runs to minimize gaps and maximize heating coverage.
- Wiring Labor: 277V circuits often require qualified electricians and appropriate breakers; include installation coordination in planning.
- Accessories: Some covers and replacement trims are specific to hydronic vs electric systems—do not mix incompatible covers with electric baseboards.
Performance Comparisons
- High Output vs Low Profile: Higher wattage units (e.g., 1500W) heat larger spaces but require appropriate circuit capacity; compact 500W–750W units suit small zones or supplemental heating.
- 240V Units In 277V Systems: 240V-rated heaters may not be directly suitable for 277V circuits. Verify manufacturer guidance or use step-down solutions only when code and electrician permit.
- Convection Efficiency: Aluminum ribbon fins and full-length heating elements typically offer consistent convective performance compared with basic coil elements.
Regulatory And Code Considerations
- Local Codes: Confirm local electrical and building code requirements for 277V fixed space heating. Commercial codes may differ from residential standards.
- Qualified Installation: Use licensed electricians for 277V installations and ensure breaker sizing and overcurrent protection match the heater rating.
Final Selection Checklist
- Verify explicit 277V or 277–240V rating on the heater specification.
- Match wattage to room heating load and available circuit capacity.
- Confirm mounting, wiring access, safety cutouts, and element durability features.
- Plan for professional installation and compliance with electrical codes.
