Winco ESH-60, 60-Inch Electric Strip Heater
The Winco ESH-60 is a 60″ commercial-grade infrared strip heater designed for food service holding. It uses a long heating element to provide constant and even infrared heating across its length, which helps prevent hot spots and keeps plates and food at consistent serving temperatures. The unit is intended for undermount installations such as pass-through stations or under-shelf mounting and includes mounting hardware and hanging chains to support different configurations.
Built-in heat reflectors focus infrared energy to maximize holding times and limit wasted output. The 60″ element makes the heater suitable for long buffet lines or multi-tray stations where even coverage is needed. Certification and commercial construction indicate suitability for food-service environments where durability and continuous operation matter.
9233-4551 Electric Heat Strip Kit For Coleman Mach
This replacement electric heat strip assembly is specified for Coleman Mach RV air conditioners (except Mach 8) and is marketed as an accessory to add heat output to compatible AC units. The kit is described as producing approximately 5,600 BTU of heating output to help eliminate chill while parked, acting as a “chill chaser” rather than a primary furnace.

The package includes a heat/cool thermostat and a two-pin heater wire receptacle to simplify installation. It replaces OEM part number 9233-4551 and is listed as compatible with Mach 48xxx (Medium Profile) and 45xxx (Low Profile) series air conditioners and heat pumps. The kit is most relevant where adding supplemental electrical heating to roof-mounted AC assemblies is required.
PYY 48 Inch Food Heat Lamp Strip – 1400W Hanging Heater
The PYY 48 Inch Food Heat Lamp Strip is a stainless steel hanging electric strip heater intended for commercial kitchens and buffet lines. The unit is rated at 1400W and claims rapid heating to around 60°C (140°F) to keep held foods warm and visually appealing. It includes adjustable chains (four chains ~1m each) to set the height above food for different tray sizes and serving situations.
Operational features include a simple rocker switch for one-touch activation and integrated warm lighting bulbs to enhance food presentation. The design focuses on fast, continuous warming with a stainless steel construction suitable for food-service environments where easy cleaning and corrosion resistance are considerations.
Coliao 24V 30W Polyimide Film Heater Plates
These polyimide film heater plates are thin, adhesive-backed heating elements intended for small-area heating tasks. Rated at DC 24V, 30W with a maximum temperature around 170°C, they are suited to precision applications such as enclosure defogging, sample warming, 3D printer beds (small), or instrument temperature stabilization.

Key characteristics include fast preheating and stable temperature during operation when paired with an external controller. Polyimide construction offers excellent heat resistance and electrical insulation. Because the films do not include integrated thermostatic control, pairing with a 24V temperature controller is advised for controlled applications. Adhesive backing simplifies mounting to flat surfaces.
Frost King HC6A Automatic Electric Heat Kit Cables
The Frost King HC6A is a self-regulating electric heat cable intended for pipe freeze protection and maintaining flow in exposed plumbing down to very low temperatures. Specified as 6 feet long at 120V and approximately 7W/ft, the cable reduces power as surface temperature rises, offering inherent temperature-responsive behavior.
Designed for both metal and plastic water pipes, the cable is intended to keep water flowing in freezing conditions and is commonly used in outdoor or unheated spaces. The self-regulating characteristic reduces the risk of overheating when sections overlap and helps improve energy efficiency compared with constant wattage heaters in variable conditions.
Buying Guide: How To Choose The Right Electric Heater Strip
Selecting the appropriate electric heater strip depends on application, power source, mounting, control needs, and safety. Below are primary considerations to evaluate before purchase.
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 Form Factor
- Food Service Heating: Choose infrared strip heaters or hanging heat lamps (e.g., Winco ESH-60, PYY units) designed for continuous operation, even heat distribution and food-safe surfaces.
- RV Or HVAC Supplemental Heat: Look for OEM-compatible heat strip assemblies specified for your AC model; these are designed to integrate with existing systems and thermostatic controls.
- Electronics Or Small-Surface Heating: Use adhesive polyimide film heaters for precise, localized heating where thin profile and adhesion matter.
- Freeze Protection: For pipes and outdoor plumbing, self-regulating heat trace cables are appropriate due to their automatic power modulation.
Power Rating And Coverage
- Match wattage to the area and heating goal. Higher wattage gives faster temperature rise but requires adequate electrical capacity and safety measures.
- For surface coverage, longer strip lengths or multiple units provide even distribution; reflectors or directional designs can concentrate heat.
Mounting, Installation, And Compatibility
- Confirm mounting style matches your space: undermount, hanging chains, adhesive backing, or cable attachment.
- For replacement kits, ensure OEM part compatibility and connector types to avoid retrofit issues.
- Professional installation may be necessary for integrated HVAC or high-voltage systems to comply with electrical codes.
Temperature Control And Safety
- Decide if you need integrated controls (rocker switches, thermostats) or external controllers for precise setpoints.
- Polyimide films generally require separate temperature controllers and sensors.
- Self-regulating cables reduce overheating risk where overlap may occur; ensure proper electrical protection and GFCI where required.
Material, Hygiene, And Environmental Considerations
- Food-service heaters should use corrosion-resistant materials (stainless steel) and be easy to clean.
- Outdoor or RV heaters need to tolerate vibration, moisture, and temperature cycling.
- For electronics, choose low-outgassing adhesives and stable dielectric materials to avoid contamination.
Energy Efficiency And Duty Cycle
- Continuous-duty commercial heaters are built for long operating hours; verify duty cycle rating for industrial or food-service use.
- Self-regulating products adjust output to ambient conditions, often saving energy where temperature varies.
Installation Environment And Regulatory Compliance
- Verify certifications or ETL/UL listings for commercial and safety-critical environments.
- Consider clearance requirements and heat-sensitive nearby materials when positioning heaters.
Comparison Perspectives
- Coverage vs. Intensity: Long infrared strips provide broad, even heating; point-source lamps provide intense localized warmth.
- Fixed vs. Adjustable Mounting: Adhesive film heaters are permanent and low-profile, while hanging lamps and strip heaters offer adjustable height and repositioning.
- Integrated vs. External Control: Choose integrated controls for simple operation; select elements requiring external controllers when precision or automation is needed.
