Do I have to use insulation?

Yes, insulation is highly recommended for use with a pipe freeze protection system for the following reasons:

·      It helps cut down on heat loss from the heated water pipe. 
·      Properly installed insulation helps keep the cable in good contact with the water pipe so that maximum surface area contact is achieved. 
·      While the cable is wet location approved, weatherproofed insulation adds an extra layer of protection. Ideally, the insulation will be nonflammable and waterproofed.
