Nice to find heat tape in this short length. I used it around a watering can for my chickens. So far, the water has stayed liquid down to 19 degrees Fahrenheit. The water does not heat up, either. It remains thawed and very cool.
Kept my water from freezing at -25F. It froze last year around 0F without the tape. Haven't even noticed a change in the Electric Bill.... Money well spent.
After having this installed on our motorhome, and after several nights of below freezing weather, this has kept our waterline warm enough to not freeze. It is well worth the purchase.
Its all hooked up. Won't know if it actually works until freeze. I did wrap my hose with insulation on top of this like. Seems good quality. the plug lights up when plugged in.
