Howdy DoIt_Yourselfsers,
Sorry to here about the fire from the heat strip on your PVC water pipe. I'm a master electrical engineer, and have used these heat strips for years on every kind of piping there is, with no electrical problems at all. My thought is that it was not wrapped properly and the excess heat is what caused the fire.
On the packing is shown a very stick specification for the amount of needed spacing for the wrap to be spaced apart from one wrap to the next wrap. In most cases where this is done incorrectly is where the excess heat builds up and the wood will be excited or the PVP type pipes will melt. Also most of the newer wrap have a thermostat built into the end where the power cord is supplied. Should ANY strip not have this built-in thermostat, one should be bought and added into the power supply wires.
In about 2000 feet of piping projects I've had installed none have ever gone bad. However, I have had four(4) projects feel due to defects in the manufacturing of the product. So do contact the manufacture of this heat strip and see if they have had any of that model strip cause over-heating and the thermostat not open the failed heat strip, due to excess heat.
My best wishes for you and a very safe heat strip use for what seems to be going a very cold winter.

My husband works at a rental store and a fellow brought in a section of heat tape that started a fire while wrapped around some PVC pipe under his house, it burned a small area of the wood structure and melted the PVC pipe which leaked and put out the fire. One lucky fellow!
But the reality of what could happen left an impression and the only way I would use that heat tape was if it was out in the open for some kind of livestock use.
My husband also watched an electric drill, plugged in but not in use, burst into flames while working in a car dealership many years ago. If it plugs in, it has the ability to burn.
I don't even leave toasters plugged in when I'm not using them.
Old and so cautious anymore,
carmen

Heat tape started a fire? I'm ok today, the weather is warm-er and I kept the faucet dripping, I figured whatever happens happens, and I'm thinking the waterline slightly froze but not entirely. Maybe I'm wrong, but for a while the drip was only hot water, finally the cold water kicked in. I had one of those new-fangled inventions installed recently, one handle faucet + spray. Today it's OK, but of course I am worried about the future in more ways than one, because we plan to get out of town for about 6 weeks during the winter. I realize I need to ask a neighbor to check on those very cold days.But I am curious about the heat tape. What it does -- and why did it start a fire? That doesn't sound good.
I know of one case where the heat tape started a fire.carmen~~~
