Cadet UCH Under Cabinet Heater 1800W 120/240V
Brand: Cadet
This under cabinet heater is designed for installation under standard cabinets and is available with both white and black grille faces to match finishes. The unit supports multi-watt and multi-volt operation, with a maximum output of 1800W, making it suitable for spaces that need stronger localized heat.
Key features include a higher maximum wattage for rapid warming and flexible installation options due to voltage and wattage settings. The unit is positioned for kitchens and bathrooms where a compact, concealed heater is preferred. The grille options help blend the device into cabinetry lines.
ALORAIR WarmHub 15 Electric Kickspace Heater

Brand: ALORAIR
The ALORAIR WarmHub 15 is a 1350W toe kick heater featuring a professional-grade heating element and a high-efficiency DC motor. The design emphasizes improved airflow (longer blower tube) to increase heating efficiency and reduce noise compared with smaller fan designs.
Operational convenience is a focus: the unit includes a front control panel, a digital temperature display, and a full-function remote. A built-in thermostat and timer allow automatic cycling so the heater stops when the set temperature is reached, supporting energy-saving operation.
AIREPUSH HTA15-ULTRA Electric Kickspace Heater
Brand: AIREPUSH
The AIREPUSH HTA15-ULTRA is a 1500W plinth heater sized for limited spaces with a low-profile 4-inch height. It uses double finned electric heating bars for fast heat conversion and claims 3-second instant heating of expelled air. The unit automatically adapts to 120V or 240V.

Controls include a digital display, built-in thermostat, and remote control for convenient temperature setup. Its compact form factor makes it suitable for under vanity bases, stairway kickspaces, or narrow cabinetry where floor and wall space are limited.
Kickspace Heater HTA15 Under Cabinet Electric
Brand: Coliah Jeeasden
This under cabinet kickspace model provides 1500W of fan-forced heat with double finned heaters for quick output. The unit’s control suite includes a built-in thermostat and digital timer, and its height is under 4 inches to fit standard toe-kick cavities.
The product emphasizes fast response and space saving. The thermostat incorporates a tolerance range to reduce cycling frequency, which the manufacturer states helps extend component life and reduces short-cycling in smaller spaces.
Toe Ductor Wall Vent Under Cabinet Ducting Kit
Brand: Toe Ductor
The Toe Ductor kit is a ducting and vent solution intended to route conditioned air to the toe-kick area beneath cabinets from a wall vent located at the same level as the toe kick. It is designed to fit under a 4-inch cavity and requires the wall vent to be on the same level as the toe kick.
Installation is described as straightforward, with no special tools required. This kit is a complementary option when an existing HVAC supply is available and you prefer ducting to a dedicated electric heater.
Buying Guide: How To Choose An Under Cabinet Heater
Selecting the right under cabinet heater depends on application, installation constraints, and performance expectations. The sections below cover the primary considerations.
Space And Mounting Constraints
- Kickspace Height: Measure the toe-kick cavity height—many models are under 4 inches, but confirm the exact cabinet clearance.
- Depth And Clearance: Ensure the heater’s depth and grille placement do not interfere with cabinet framing, plumbing, or electrical runs.
- Mounting Type: Some heaters mount flush under cabinets, while ducting kits require a compatible wall vent at the same level.
Power, Voltage, And Heat Output
- Wattage: Common under-cabinet heaters range from ~1350W to 1800W. Higher wattage delivers faster, stronger heat but draws more current.
- Voltage Options: Check whether the unit supports 120V, 240V, or both. Multi-volt models offer installation flexibility.
- Heat Distribution: Fan-forced units with longer blower tubes or higher-efficiency motors can move heat farther into the room versus passive units.
Controls, Thermostat, And Features
- Built-In Thermostat: A thermostat prevents overheating and reduces energy use by only running when needed.
- Remote & Timer: Remote control and programmable timers add convenience for hard-to-reach installations.
- Noise Level: Motor-driven fans vary—look for DC motors or units advertised as low-noise if quiet operation is important.
Energy Use And Efficiency
- Auto Shutoff: Thermostat and timer functions help reduce runtime and electricity consumption.
- Duty Cycle: Consider how long the heater will run in your climate—continuous high-power use increases operating cost.
- Targeted Heating: Under-cabinet heaters are intended for spot heating; using them to heat an entire home is inefficient compared with central HVAC.
Safety And Compliance
- Certifications: Verify UL/ETL or other recognized safety listings for electrical appliances in living spaces.
- Overheat Protection: Look for built-in thermal cutoffs and safety features to prevent sustained overheating.
- Location: Avoid placing under-cabinet heaters where they may be obstructed by stored items or where moisture exposure is excessive unless rated for that use.
Installation Considerations
- Electrical Requirements: Determine if a dedicated circuit is needed based on wattage and local code. Higher wattage or 240V models may require professional wiring.
- Retrofit vs New Cabinets: Retrofit installs may require cutting grille openings and routing electrical wiring. New constructions can accommodate cleaner installations.
- Ducting Options: If you have an existing HVAC run, a ducting/register kit can deliver conditioned air to the toe kick without an independent heater.
Compatibility And Aesthetics
- Grille Finish: Choose a grille color or finish that matches your cabinetry. Some heaters include multiple grille options.
- Low-Profile Design: For modern kitchens, a slim grille helps maintain continuous toe-kick lines.
Performance Comparison Perspectives
- High Output vs Lower Wattage: Higher wattage (e.g., 1800W) delivers stronger heat quickly but requires adequate electrical service. Lower wattage with efficient airflow can perform similarly in smaller rooms while drawing less current.
- Dedicated Heater vs Ducting: Dedicated electric kickspace heaters are useful in rooms without central heating. Ducting kits are practical when a supply register is nearby and you prefer integration with central HVAC.
- Controls & Automation: Built-in thermostats and timers reduce energy waste. Remote controls increase usability in tight spaces where access is limited.
Maintenance And Service
- Filter And Fan Care: Some fan-forced units have grills that allow occasional vacuuming of dust. Confirm maintenance access before installation.
- Serviceability: Check manufacturer guidance on warranty, replacement parts, and qualified service for electrical components.
Final Selection Tip: Match the unit’s wattage and airflow to the size of the room and the mounting clearance available. If you have an existing wall HVAC supply at toe-kick level, a ducting kit and register may be a lower-maintenance, integrated option; otherwise, a plinth/kickspace heater with thermostat and timer provides targeted heat and control.
