What does a heat trace system look like?

Before beginning the installation process, you may want to familiarise yourself with what a heat trace system entails. A standard system usually includes the following components:

• A control panel or heat trace thermostat
• Ambient temperature sensor
• A power connection box to connect power from the breaker
• Cable termination box
• Heat tracing cables
• Insulation jacket
• Light indicators to monitor output

How to install a heat trace system?

Pre-installation process

We always recommend users go through a few pre-installation processes to ensure that the system will work effectively. Here are the essential steps to take before installing your heat trace system.

Step 1. Check your piping system

Check that your piping system is installed correctly, in proper working order, and has been adequately pressure tested. 

Step 2. Determine the length of the pipe or equipment to be heated

The best way to gauge the cable length you require is to walk the length of your piping system to determine the route of the heat tracing cables. Ensure the surface of the pipes are free from rust, dirt, and any sharp edges or objects. If there is any old heat tape or other combustible materials, remove them.

Step 3. Choose the appropriate heat tracing cable

With various types of heat tracing cables available on the market, it is imperative that you select the appropriate one for your piping system. Once you have confirmed the cable is the correct type and output, check for any damage before testing its electrical integrity using a megger. 

Step 4. Check the power supply

You will also have to ensure your electrical supply is sufficient to power your heat trace system. Check the system’s requirements and consult an electrician to verify that the power supply is adequate.

Step 5. Gather the necessary tools and hardware

To ensure the installation process goes smoothly, you will require the correct tools for the job. So ensure you have the necessary mounting hardware, such as your glass tape and heat trace termination kit, to complete the system. 

Installation process

After completing the pre-installation processes, you are now ready to install your heat trace system. 

Step 1. Clean the surface

Before you begin, we recommend cleaning the surface where the cable will be installed to ensure it is dirt- and debris-free so that the heat tracing cable will adhere properly to the surface of the pipes.

Step 2. Mount the heat tracing cable

We always recommend deferring to the manufacturer’s instructions when mounting the heat tracing cable, as the spacing between the cable and the pipe depends on the type of cable used and the application. 

Step 3. Install the thermostat

The heat trace thermostat helps regulate the temperature of your heat trace system. As such, it should be installed at a convenient location that is easily accessible. For example, near the power supply.

Step 4. Connect the heat tracing cable to the thermostat and power supply

Generally, the cable will be connected to the thermostat or temperature controller using a splice kit and then linked to a power source using a plug or hardwired connection. If you are unsure, we recommend checking the manufacturer’s instructions.

Step 5. Test the system

Lastly, once the heat trace system is installed, it is time to test it to ensure it functions correctly. You should also check the temperature of your pipe and equipment regularly to ensure the system maintains the desired temperature.
