Living or working in an RV or mobile unit offers incredible freedom, but it also comes with unique challenges, especially when the temperature drops.
A sudden cold snap can lead to frozen pipes, causing significant damage and disrupting your daily routine. Protecting your plumbing from freezing is not just a matter of convenience; it’s a critical part of maintaining your vehicle.
Heat trace systems offer a reliable solution to prevent an RV plumbing freeze and ensure your water keeps flowing all winter long. This article will explain how heat trace systems provide effective portable protection for your pipes.
We will cover the different types of heat trace cables, how they work, and the essential factors to consider when choosing the right system for your needs.
By understanding these systems, you can confidently prepare your RV or mobile unit for cold weather, ensuring comfort and peace of mind on the road.
The Basics of Heat Trace Technology
Heat trace technology, also known as heat tape, is a system designed to prevent pipes from freezing by applying a consistent, controlled amount of heat.
It involves an electrical heating cable that runs along the length of a pipe, keeping the fluid inside at a temperature above its freezing point.
How Does It Work?
The core of a heat trace system is the heating cable. When connected to a power source, this cable generates heat, which is then transferred directly to the pipe it’s attached to.
This process maintains the water temperature, preventing the formation of ice that can cause pipes to burst.
Modern systems often include thermostats to regulate the temperature, activating the heat only when needed to save energy and prevent overheating.
Components of a Heat Trace System
A complete heat trace system typically includes several key parts:
- Heating Cable: The element that produces heat.
- Thermostat: A device that monitors the ambient or pipe temperature and turns the system on and off.
- Insulation: Placed over the pipe and heating cable to retain heat and improve efficiency.
- Power Connection Kit: Components needed to connect the cable to a power source safely.
- Application Tape: Special tape used to secure the heating cable to the pipe.
Types of Heat Trace Cables for Mobile Units
When selecting a heat trace system, you’ll encounter two main types of heating cables: self-regulating and constant wattage. Each offers distinct advantages for mobile unit heating.
Self-Regulating Cables
Self-regulating cables are the most popular choice for RVs and mobile units. Their design allows them to automatically adjust their heat output along their entire length based on the surrounding temperature.
- How they work: The cable has a conductive polymer core. As the temperature drops, the core creates more electrical paths, increasing heat output. As it warms up, the electrical paths decrease, reducing heat.
- Benefits: This technology makes them highly energy-efficient and safe, as they are less likely to overheat. They can also be cut to any length during installation, offering great flexibility.
Constant Wattage Cables
Constant wattage cables provide a consistent heat output per foot, regardless of the ambient temperature.
- How they work: These cables have a fixed resistance, delivering a steady amount of heat as long as they are powered on.
- Benefits: They are generally less expensive upfront than self-regulating cables. However, they require a thermostat to prevent overheating and are less energy-efficient. They cannot be overlapped or cut to length in the field, which requires more careful planning during installation.
Installing a Heat Trace System on Your RV
Proper installation is crucial for the effectiveness and safety of your heat trace system. While the process is straightforward, it requires attention to detail.
Preparation Steps
- Clean the Pipes: Ensure the surfaces of your pipes are clean and dry before you begin.
- Measure and Plan: Determine the length of heating cable needed by measuring all the pipes, valves, and faucets you intend to protect.
- Gather Your Tools: You will need the heat trace kit, application tape, insulation, and basic tools like a tape measure and utility knife.
Installation Process
- Attach the Cable: Run the heating cable straight along the bottom of the pipe. For plastic pipes, it’s often recommended to use aluminum foil tape first to help distribute heat evenly. Secure the cable to the pipe every 12 inches with the provided application tape.
- Address Valves and Faucets: When you reach a valve or spigot, wrap it with an extra loop of cable to ensure it receives enough heat.
- Install the Thermostat: Place the thermostat’s sensing bulb firmly against the pipe in the coldest anticipated location, away from the heating cable itself, to get an accurate reading.
- Insulate Everything: Cover the pipe and heating cable with weatherproof, fire-resistant insulation. This step is vital for retaining heat and maximizing energy efficiency.
- Connect to Power: Follow the manufacturer’s instructions to safely connect the system to your RV’s power supply.
Safety Considerations for Portable Protection
Safety should always be the top priority when working with electrical heating systems. Following manufacturer guidelines and best practices ensures your system operates safely.
- Use Ground-Fault Protection: Always connect your heat trace system to a circuit protected by a Ground-Fault Circuit Interrupter (GFCI) to prevent electrical shocks.
- Never Overlap Cables: Unless you are using a self-regulating cable specifically approved for overlapping, never cross the heating cable over itself, as this can create a dangerous hot spot.
- Inspect Regularly: Check your system for any signs of damage, such as frayed wires or cracked insulation, before the start of each cold season.
- Choose the Right Product: Ensure the heat trace system you select is rated for use on the type of pipes in your RV (e.g., PVC, PEX, metal).
Energy Efficiency and Cost
The operational cost of a heat trace system is an important factor. Self-regulating systems are more energy-efficient because they only produce heat where and when it’s needed.
While the initial investment might be higher, the long-term energy savings can be significant. Using high-quality insulation is another key factor in reducing energy consumption, as it minimizes heat loss and allows the system to run less frequently.

Choosing the Right System for Your Needs
Selecting the best heat trace system depends on your specific circumstances, including your climate, pipe materials, and budget.
- For Extreme Cold: If you frequently travel in areas with severe winter weather, a self-regulating cable is the most reliable choice.
- For Occasional Use: For those who only need protection during infrequent cold snaps, a constant wattage system with a good thermostat can be a cost-effective solution.
- For Plastic Pipes: Always use a system that is specifically approved for plastic pipes to avoid damage. Self-regulating cables are generally the safest option.
Protect Your Investment This Winter
A heat trace system is a smart investment for any RV or mobile unit owner braving cold climates.
It provides dependable portable protection against the costly damage of an RV plumbing freeze, giving you the freedom to travel year-round without worry.
By choosing the right type of system and installing it correctly, you can ensure your water systems remain functional, no matter how low the temperature drops.
