How to Install Flexible Duct Heating

 

Installing flexible duct heating is a challenging task for most people across the globe. This is not because it is a tough task. It is just because they think so. Experts and experienced technicians in flexible duct heating believe that the task of installation is easier than what people assume it to be if one has all the tools in hand and follow the instructions religiously. Another term for flexible duct heating is the flex duct heating. It can also be defined as a substitute to the more severe and expensive technique of metal duct heating. There are many advantages of using a flexible ducting heating system. The major advantage is that, it comes pre-insulated. The hosing of flex  offers enough elasticity to fit all around the corners. This means that there is no need to seal the joints or using attachments to the elbow. The process of installation requires only a few steps. This will also save a lot of time and money. If you want to install flexible duct heating all on your own, here are some instructions to make sure that you get the task right. Make sure you follow all the steps closely and have the tools handy before undertaking the task.

Tools and Materials Needed:

  • Wire cutters
  • Duct tape
  • Scissors
  • Utility knife 

Step 1 - Trimming

Trim a portion of flex duct hosing. This allows good fit into the space available between the 2 attachment sites. Puncture the hose with the help of the utility knife. Now start cutting. You must end the trimming via using scissors. Use a wire cutter for snipping the wires available inside the hose. You can do this easily because the wires are flexible.

Step 2 - Checking the Hose

This step includes spreading the hosing evenly amid the 2 attachment points. Make sure that there is no sag or slack inside the hose. Strictly avoid bending the hose too much, especially when trying to get around a corner of the hosing. It is true that the hose is flexible, but trying to get to a tight turn can easily result in to a disastrous puncture in the hose. This will ultimately lead to undesirable leaks.

Step 3 - Connecting

Properly attach each end of the hose to the attachment points. Here, the main focus should be on rolling the outer shell back for 2 to 3 inches, starting from the internal liner. The internal lining is inserted into the duct. Make sure you wrap the external shell about the duct exterior. Sealing the link via wrapping a duct tape is important. This should be done to each end till you hook up the entire network of duct.

Step 4 - Testing

Turn on the heating system to check for any leaks. Pay special attention to the air coming out from attachment areas. If leaks are found, seal the area of the hose with duct tape. Finally, you have successfully installed the flexible duct heating system.

Tips and Warnings

  • Purchase additional hose than the required measurement, which may be required if mistakes occur during trimming.
  • Take extreme care when fixing the hose to the metal parts of the heating system because the sharp edges of the metal parts can damage the hose.
