The HTA15-PRO mirrors many features of the ULTRA model with 1500W output, 3-second instant heating, and automated voltage recognition. It integrates a digital thermostat and timer for scheduled operation and temperature maintenance.
Its low profile (about 4 inches) is designed specifically for cabinet kickspaces, stairways, and vanities. The listing emphasizes simple setup and control—suitable where centralized heating is limited or absent and targeted warmth is needed.
Key technical notes include the double-finned heating bars for efficient heat conversion and the combination of thermostat plus timer to limit runtime and optimize energy use. The unit’s feature set targets small zones requiring quick, controllable heat delivery.
ALORAIR WarmHub 15 Kickspace Heater
The ALORAIR WarmHub 15 is a 1350W toe-kick heater engineered for rapid heating with professional-grade components. It pairs a high-efficiency heating element (listed at 4520 BTU/h) with a DC blower motor running at 2769 RPM to boost airflow and reduce operational noise.
Design highlights include a 200mm extended blower and a heating tube intended to increase air volume and improve heating efficiency by roughly 30% according to the manufacturer. Controls include a front panel display plus a full-function remote for adjustments without bending down.

Built-in features include a thermostat and timer intended to stop heating when the set temperature is reached, contributing to energy savings. The combination of stronger airflow and quieter operation positions this model for slightly larger kickspace areas or installations where noise matters.
KING KT2415-MW-B Multi-Watt Kickspace Heater
King Electric’s KT2415-MW-B offers multi-watt options and is rated for 240–208V operation with selectable wattages (1500W–1125W). It uses a NiChrome open coil element for quick heat transfer, designed to fit under kitchen and bath cabinets.
The multi-watt capability allows installers to tailor the heater’s output to a room’s heating requirement or to accommodate existing electrical circuits. The open coil element is a simple, proven heating method emphasizing reliability and fast response.
For projects where matching heater output to circuit capacity or room size is necessary—such as remodeling or retrofit work—this model provides installation flexibility through its selectable wattage feature and compact kickspace fit.
KING KTW1215-HLS-RG-W Horizontal/Vertical Heater
This KING KTW model supports both vertical and horizontal installation and features a hi-low wattage switch with a recessed grill for discreet placement. It is rated at 1500W / 120V and uses a NiChrome open coil for fast heat delivery.
The ability to install horizontally or vertically increases placement options in tight cabinetry, recessed toe kicks, or where airflow direction matters. The hi-low switch allows on-the-fly adjustment between power levels to address varying heat demands.
For installations requiring orientation flexibility and a low-profile discharge point, this model’s recessed grill and multi-orientation design help adapt to different cabinetry layouts while providing direct toe-level warmth.
Buying Guide: How To Choose A Kickspace Heater
This buying guide covers the main considerations when selecting an electric kickspace heater, comparing performance, installation, and safety attributes from multiple perspectives.
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.
Heating Capacity And Wattage
- Match Wattage To Space: Kickspace heaters commonly range from ~750W to 1500W. Higher wattage provides faster and stronger heat for larger or less-insulated spaces. For tight bathroom or vanity zones, 1350–1500W is a common choice.
- Multi-Watt Options: Models with selectable wattages allow tuning to circuit limitations and room load, useful in retrofits or varied room sizes.
Thermostat, Timer, And Controls
- Built-In Thermostat: Maintains target temperature and reduces cycling; look for digital display accuracy and control range.
- Timer And Remote: Timers enable scheduled operation for energy savings. Remotes and front panels increase convenience for under-cabinet units.
Airflow And Noise
- Blower vs Passive Convection: Fan-forced models deliver faster heat distribution; check motor type and RPM if noise matters. DC motors tend to be quieter.
- Extended Blowers: Longer blower assemblies can move more air and warm a larger area within the same footprint.
Size, Mounting, And Orientation
- Low Profile Height: Typical kickspace heights range 3.8″–4″. Confirm cabinet toe-kick dimensions and clearance before purchase.
- Vertical/Horizontal Mounting: Choose models that fit your cabinet layout—some units support both orientations for recessed or side installations.
Installation Voltage And Compatibility
- Voltage Options: Verify whether the heater is factory-set to 120V or 240V and if it supports automatic voltage recognition or rewiring for alternate voltages.
- Electrical Circuit Capacity: Confirm available circuit amperage and whether the heater’s wattage aligns with building wiring and breakers.
Heating Element And Efficiency
- Open Coil vs Finned Tubes: Open coil (NiChrome) elements heat quickly but may be simpler in design; finned or double-finned heating bars often improve convection efficiency.
- Energy Control: Thermostats and timers reduce runtime. Consider models with automatic shutoff or adaptive thermostat behavior to minimize energy use.
Safety Features
- Overheat Protection: Look for high-temperature alarms, automatic shutoffs, and limit switches to protect against overheating.
- Certifications: Verify electrical and safety certifications where available to ensure compliance with local codes.
Durability And Serviceability
- Build Quality: Metal housings and professional-grade blowers improve longevity in high-use areas.
- Parts And Support: Consider manufacturer support for replacement grilles, motors, or elements if long-term maintenance is likely.
Comparison Perspectives
- Quick Heat Needs: Models with high-watt output and fan-forced designs provide the fastest warm-up times.
- Quiet/Continuous Comfort: Units with DC motors and extended blowers balance airflow and low noise for continuous operation.
- Installation Flexibility: Multi-watt or multi-voltage units are advantageous in renovations where wiring or circuit limits vary.
- Energy-Conscious Choice: Thermostat and timer features, plus lower wattage options, support reduced energy consumption when full power isn’t required.
