- Dual Output Configuration: Allows operation on different circuit capacities for greater installation flexibility.
- Thermal Protection: Built-in overheat protection reduces fire and component-damage risk.
- Robust Coil Support: Proprietary dual coil support system designed for durability in workshop conditions.
This model is commonly chosen where robust construction and the option to downrate wattage for existing electrical setups are required. Hardwired installation and proper breaker sizing are essential for safe operation.
Goodman 10 kW Heat Kit
The Goodman HKTSN10X1 is an electric heat kit intended to be integrated with compatible Goodman air handler models. It delivers approximately 10 kW (≈34,250 BTU/hr) at 208/240 V, providing fully electric heat without gas lines.
- Air Handler Integration: Designed for specific Goodman AHVE/AMVE/AMVT/AMST/AWST air handlers—confirm model compatibility prior to purchase.
- Fully Electric Operation: Uses line voltage heating elements within the air handler, eliminating gas infrastructure.
- Rated Voltage: 208/240 V single-phase, 60 Hz—intended for HVAC wiring configurations.
This kit suits retrofit or replacement scenarios when a heat source needs to be provided through the furnace/air handler assembly. Proper electrical and HVAC compatibility checks are critical before installation.
KING 10KW ECO2S+ Garage Heater
The KING KB2410-1-ECO2S-PLUS uses a 2-stage heating approach and an ECO2S+ energy-saving design to use the minimum wattage needed. It includes a remote temperature sensor for better ambient accuracy.
- 2-Stage Heating: Automatically selects the lower wattage setting when conditions allow, improving efficiency.
- Remote Temperature Sensor: Helps locate the control point for a more representative ambient readout.
- Energy-Saving Design: ECO mode reduces runtime when the set temperature is near the ambient target.
As a ceiling-mounted fan-forced heater with staged control, this unit balances high output with efficiency features suitable for garages and medium-sized shops. Electrical supply, mount location, and sensor placement influence performance.
Supplying Demand 10kW Heater Kit
The Supplying Demand HKR-10C is an electric heater kit intended for specific air handler models, supplying 10 kW of open-coil heating with the required limit controls and a circuit breaker. It lists alternate part numbers for cross-reference.
- Kit Components: Alloy open coil heater elements plus limit controls and circuit breaker provisions.
- Electrical Specs: 34,100 BTU, 39.6 A at 240 V single-phase, 60 Hz.
- Model Fitment: Fits model-specific air handlers—verify compatibility with the target unit.
This kit addresses HVAC integrators and DIY installers needing a matched heater element and control package for a compatible air handler. Confirm wiring, breaker size, and mechanical fit before installation.
Buying Guide: Key Considerations For 10 kW Electric Heaters
When evaluating 10 kW electric heaters, focus on application, electrical capacity, safety controls, and installation requirements. Below are the main points to compare and verify prior to purchase.
Determine The Intended Application
Clarify whether the heater will be used as a ceiling-mounted fan-forced unit for a garage or as a heat kit integrated into an air handler. Ceiling heaters deliver direct warm air to open spaces, while heat kits provide whole-house or ducted distribution from the HVAC system.
Electrical Service And Circuit Compatibility
10 kW at 240 V typically draws about 40–42 amps. Confirm the building service, panel capacity, and available breakers. Some units offer selectable outputs (for example, 10 kW or 7 kW) to match different circuit ratings, which increases installation flexibility.
Mounting And Physical Fit
Ceiling-mounted units require secure structural support and correct clearance for louvers and airflow. Heat kits must be physically compatible with the air handler model. Verify cabinet space, mounting brackets, and duct or airflow path limitations.
Controls, Thermostats, And Sensors
Look for integrated thermostats, remote sensors, and ECO modes that reduce runtime and prevent overshoot. Remote temperature sensors can improve accuracy if the heater is mounted high or away from the workspace.
Safety Features And Overheat Protection
Essential safety items include thermal cutoffs, limit controls, and automatic shutoff. Heat kits often include limit switches and require correct breaker sizing. Fan-forced models should list overheat protection and auto-shutdown behavior.
Energy Efficiency And Staged Heating
Staged heating (two-stage or ECO modes) can reduce energy consumption by running lower wattage when conditions allow. Consider models with adaptive controls to limit runtime and reduce electrical demand peaks.
BTU Output And Coverage Expectations
Manufacturers commonly provide BTU estimates (10 kW ≈ 34,000 BTU/hr). Actual coverage depends on insulation, ceiling height, and outdoor temperature. Use BTU estimates as a starting point and consult heat loss calculations for precise sizing.
Installation Complexity And Professional Requirements
Hardwired 240 V installations often require a licensed electrician and, for HVAC heat kits, a qualified HVAC technician to ensure proper wiring, breaker configuration, and safety control integration. Verify code compliance and permit needs.
Compatibility And Replacement Part Numbers
For heat kits, confirm compatibility with the air handler model and any alternate part numbers. Cross-referencing OEM part numbers reduces the risk of purchasing a kit that doesn’t physically or electrically fit your system.
Durability, Maintenance, And Coil Types
Open-coil alloy elements are common for heat kits; coil support and construction quality matter for long-term reliability. Forced-air heaters require occasional fan and element inspection. Check manufacturer guidance for routine maintenance intervals.
Comparison Perspectives
- Flexibility: Units with selectable outputs (DEWALT) are preferable where electrical capacity may vary.
- Integration: HVAC heat kits (Goodman, Supplying Demand) are best for ducted systems tied into an air handler.
- Energy Control: Models with ECO modes and remote sensors (TEMPWARE, KING) support efficiency and occupant comfort.
- Professional Use: Rugged designs and thermal protection are priorities for heavy workshop or commercial use.
Prioritize safety and compatibility checks: confirm voltage, amperage, breaker size, mounting, and HVAC model fitment. For most installations, consult electrical and HVAC professionals to ensure the heater meets code and performs reliably.
