Review on Pre-Assembled 6Ft Self-Regulating Pipe Heating Cable - 120V By HEATIT For Efficient Winter Protection by Todd Stepp

We used this on out food truck's water lines. They are 1/2" lines so we just ran this cable straight down each line, then wrapped it in foam and ziptied it all. So far its been working great - the only issues we've seen is that the brass LPD (low point drain) freezes because there really isn't a way to wrap an end in heating tape. So for those we just have to wrap in a small heat blanket (like what you'd put on your shoulder).Overall we're happy with the results - our only complaint would be the price - I think it's a bit on the expensive side like everything else these days.Recommended!
