Hatco C-15-240-1-QS Booster Heater, Electric 240v/60/1-ph, 15kW

The Hatco C-15-240-1-QS is specified as a 15 kW, 240V, single-phase booster heater intended for commercial applications where supplemental electric heat is required. The manufacturer lists an included one-year parts and labor warranty. Its design suits integration into foodservice or commercial equipment where a booster-style electric heater is needed for increasing fluid or air temperatures. Installation typically requires appropriate circuit protection and wiring sized for a 15 kW load at 240V single-phase. The unit’s listed warranty and commercial orientation make it a relevant candidate when a true 15 kW, 1-ph solution is required.
Global Industrial Portable Electric Salamander Heater, 240V 15 KW 1 Phase With 25’L Cable

This Global Industrial unit is a 15 kW, 240V, single-phase portable salamander heater intended for jobsite or workshop use. Key features include 10″ wheels for mobility, a 25′ power cable, and a design intended for direct-wire installation. The product notes require a 75 Amp circuit breaker, which aligns with the expected current draw for a 15 kW load at 240V. The portability and cable length make it suitable for temporary or mobile heating where a heavy-duty cord and wheelbase assist positioning. Direct-wire setup and breaker sizing should be verified with local electrical code and an electrician prior to installation.
Dr Infrared Heater DR-P3150, 15KW_3-Phase, Gray

The DR Infrared DR-P3150 is described with single or three phase flexibility and voltage options from 208 to 480 volts. Although listed under a 3-phase model family, its flexibility makes it relevant where a site may use either single-phase or three-phase service. The unit emphasizes uniform air distribution for filling larger spaces and an overheat-protected motor with permanently lubricated, enclosed bearings for durability. For a 240V single-phase application, confirm the manufacturer’s wiring and configuration options that allow single-phase connection at the intended voltage. Professional electrical review is recommended when adapting multi-voltage equipment to a specific site.
Goodman HKR3-15 15 kW 208/240 V 3 Phase Electric Heat Kit

The Goodman HKR3-15 is an OEM-style 15 kW electric heat kit specified for 208/240V 3-phase air handlers and packaged units. Its listing focuses on compatibility with Goodman systems and extended manufacturer warranty options when registered. This kit is intended for integration into existing HVAC equipment rather than standalone space heating. For single-phase 240V requirements, this 3-phase kit is not a direct match unless the installation environment provides appropriate phase conversion or the equipment supports 1-ph wiring. The product is relevant for contractors and HVAC technicians specifying factory kits for commercial air handling systems.
Dura Heat EWH5510 Electric Forced Air Heater with Remote Control 17,060 Btu, Yellow, Large

The Dura Heat EWH5510 is a hard-wired 240V electric forced-air heater designed for garage and workshop environments. While the model listed is rated near 5,000W (17,060 BTU) rather than 15 kW, its features include remote control with adjustable thermostat and an LED display with settable temperatures. The product is relevant for readers comparing the control convenience and installation differences between high-power fixed wiring (>10 kW) and smaller hard-wired garage heaters. Installers should note this model requires professional installation and is intended for spaces up to several hundred square feet depending on insulation and climate.
Buying Guide: How To Choose A 15 kW 240V Single-Phase Electric Heater
Selecting the right 15 kW, 240V, single-phase heater requires attention to electrical capacity, mounting and mobility, application type, and compliance. Below are the critical considerations and comparison perspectives to guide a purchasing decision.
Electrical Compatibility And Circuit Requirements
- Amperage And Breaker Size: A 15 kW load at 240V draws approximately 62.5 amps continuous; circuits and breakers are sized per local code and continuous-load rules. Many listings recommend a 75A breaker—verify with an electrician.
- Single-Phase vs Three-Phase: Confirm that the heater supports single-phase 240V. Some commercial models are three-phase only or offer configurable voltage; ensure the unit’s wiring options match site service.
- Voltage Range And Transformations: Some units offer 208–480V range; check whether the manufacturer provides a single-phase wiring diagram for 240V.
Installation Type: Portable, Wall/Ceiling, Or OEM Kit
- Portable Units: Provide mobility for temporary heating jobs; include heavy-duty cables and wheels. Consider cord length and plug/connector type if not direct-wired.
- Fixed Units (Wall/Ceiling): Save floor space but require mounting hardware and hard-wiring; suitable for workshops and garages.
- OEM Heat Kits: Intended for integration into air handlers or packaged systems; these kits are not standalone space heaters and are suited for HVAC professionals.
Safety Features And Compliance
- Overheat Protection: Motor thermal protection and element cutouts reduce fire risk and protect the unit.
- ETL/UL Listings: Confirm third-party listing for commercial installations where code inspections require certified equipment.
- Thermostat And Controls: Built-in thermostats, remote controls, or external control compatibility affect energy use and comfort management.
Application And Heat Distribution
- Space Size & Insulation: Match kW to the area, accounting for insulation quality, ceiling height, and target temperature rise.
- Air Distribution: Fan-forced or salamander-style units provide directed airflow; uniform distribution models are better for larger rooms.
- Use Case: Workshop, garage, commercial foodservice booster, or integration with HVAC impacts product selection.
Installation And Service Considerations
- Professional Installation: High-power electric heaters typically require licensed electrician installation and proper breaker sizing.
- Replacement Parts And Warranty: Check manufacturer warranty terms and availability of replacement elements or controls.
- Maintenance: Consider accessibility for element or fan service, and whether motors are permanently lubricated or require periodic servicing.
Comparison Perspectives
- Power Match: For a strict 15 kW, 240V single-phase requirement, verify the product label explicitly matches that specification (Hatco and Global Industrial entries do).
- Flexibility vs Simplicity: Units offering multi-voltage or phase flexibility (DR Infrared) can adapt to different sites but may require additional configuration.
- Portability vs Permanence: Portable salamander heaters enable temporary deployment, while fixed hard-wired units are more appropriate for permanent climate control.
- OEM Kits vs Standalone Units: Heat kits integrate into HVAC systems and are typically intended for professional installation, not as standalone room heaters.
Prioritize matching the heater’s rated voltage and phase to your facility’s service, confirm breaker and conductor sizing with an electrician, and choose the installation style that fits your operational needs. For professional or commercial installations, rely on manufacturer documentation and certified electricians to ensure safe, code-compliant setup.
