The DEWALT DXH1000TS offers a dual-output capability: it can operate at 10 kW (50 amp) or at 7 kW (30 amp). This dual-mode design provides flexibility when circuit capacity varies or when reduced output is desired.
Key mechanical features include a proprietary dual coil support system to handle the heating elements and thermal protection for safety. The unit is a fan-forced type intended for garage and shop use and is designed for hardwired 240V connections.
Because it supports two output modes, this model may be useful where electrical service constraints or staged power requirements are factors in installation planning. Professional electrical evaluation is recommended before installation.
Goodman 10 kW 208/240V Electric Heat Kit
The Goodman HKTSN10X1 is a factory-compatible 10 kW heat kit designed to integrate with select Goodman air handlers. It operates at 208/240V single-phase and offers approximately 34,250 BTU per hour according to the manufacturer.
This kit is described as fully electric, eliminating the need for gas lines. It is intended to be installed inside compatible Goodman air handler units and may simplify installation by using the air handler’s internal electrical connections rather than external receptacles.

Check model compatibility before purchasing. The manufacturer lists specific Goodman air handler models that pair with this kit; confirming the model number of your air handler is essential for proper fit and operation.
KING KB2410-1-ECO2S-PLUS 2-Stage Heater
The KING KB2410-1-ECO2S-PLUS features a two-stage heating design and an ECO2S+ energy-saving system that aims to use the lowest wattage necessary. The kit includes an ECO2S+ remote temperature sensor to monitor the occupied space rather than just the unit location.
Two-stage operation commonly allows the heater to switch between lower and higher wattage settings automatically, which can improve efficiency and reduce cycling. The remote sensor placement capability helps maintain target temperature where people are located.
Installation is for a 240V supply. As with other ceiling or air-handler-mounted electric heaters, wiring and local code compliance should be verified prior to installation.
Supplying Demand HKR-10C Heater Kit With Breaker
The HKR-10C heat kit supplies a 10 kW alloy open coil heater and includes necessary limit controls and a circuit breaker. The manufacturer lists alternate part numbers and states the unit outputs approximately 34,100 BTU with an amp draw near 39.6A at 240V.
This kit is aimed at HVAC technicians installing electric heat elements in compatible air handlers. The inclusion of limit controls and a circuit breaker is relevant for meeting protective device requirements during installation.
Compatibility with specific air handler models should be confirmed. The kit format requires careful wiring and compliance with electrical and mechanical codes for safe operation.
Buying Guide For 10 kW Electric Heaters
This buying guide outlines objective considerations to help compare 10 kW electric heaters for garages, workshops, or air-handlers.
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.
Application And Mounting Type
- Ceiling/Wall Mounted Fan-Forced Units: Designed to blow heated air into open spaces (garages, shops). Consider airflow direction, louvers, and mounting hardware.
- Air Handler Heat Kits: Intended to be installed inside a compatible air handler. Ensure kit compatibility with the existing HVAC unit model.
Electrical Requirements And Circuit Capacity
- 10 kW at 240V
- Confirm whether the product is hardwired or requires a plug. Most 10 kW units are hardwired and may require a dedicated breaker and conduit to meet code.
- Consult a licensed electrician to size breakers, wire gauge, and verify panel capacity before purchase.
Compatibility And Integration
- For heat kits, check manufacturer compatibility lists and air handler model numbers.
- For standalone heaters, verify mounting clearances, ducting or airflow obstructions, and available ceiling or wall space for installation.
Control Options And Temperature Sensing
- Built-In Thermostats: Provide basic temperature control and setpoints.
- Remote Controls & External Sensors: Remote thermostats or wireless sensors allow temperature sensing in the occupied area rather than at the unit, which can reduce overshoot.
- Timers and ECO Modes: Automated timers and ECO modes can help reduce run time and energy consumption by adapting operation to ambient conditions.
Safety Features
- Overheat Protection: Automatic shutoff in case of excessive internal temperature prevents damage and fire risk.
- High-Limit Controls: For heat kits, built-in limit controls and required breakers or fuses are important for meeting safety and code requirements.
- Thermal Cutouts and Thermal Protection: Verify the presence of thermal fuses or sensors designed to interrupt power under fault conditions.
Performance Ratings And Coverage
- Manufacturers commonly express output in watts and BTU/hr. A 10 kW unit is often rated near 34,000 BTU/hr.
- Coverage estimates depend on ceiling height, insulation, and ambient temperature. Use conservative estimates for poorly insulated or high-ceiling spaces.
Energy Efficiency And Staging
- Two-Stage Or Dual-Output Models: Offer the ability to operate at lower wattage for milder conditions, reducing electrical demand and cycling frequency.
- ECO Modes: Some units include adaptive controls that lower output or cycle the heater based on sensor feedback to reduce runtime.
Installation And Maintenance Considerations
- Hardwired 240V installations usually require a licensed electrician and may require permits.
- Periodic maintenance typically includes cleaning fan/intake areas, checking wiring connections, and verifying limit control operation.
- For heat kits inside air handlers, ensure coil and housing clearance and follow manufacturer instructions to maintain warranty and safe operation.
Comparison Perspectives
- Standalone Garage Heaters vs. Air Handler Kits: Standalone units are optimized for open-volume heating and often include fans and louvers. Air handler kits heat air distributed through ducts and may better integrate with existing HVAC systems.
- High Output vs. Staged Output: Continuous high-output models deliver full 10 kW heating; staged or dual-output models provide flexibility and can reduce peak electrical load.
- Included Controls: Models with remote sensors and ECO logic provide more localized comfort control than units relying solely on unit-mounted thermostats.
Regulatory And Code Compliance
- Confirm that installation meets local electrical codes, National Electrical Code (NEC) requirements for branch circuit sizing, and any local permitting rules.
- For professional installations (air handler kits or hardwired heaters), retain installation documentation and wiring diagrams for inspection and future service.
Final Selection Checklist
- Verify the electrical service capacity and breaker sizing for a 10 kW load.
- Confirm physical mounting location, airflow direction, and required clearances.
- Ensure compatibility for air handler heat kits with your HVAC model.
- Review available controls (thermostat, remote sensor, timer) and safety features.
- Plan for professional installation if hardwired or integrated into an HVAC system.
