Question: will this keep a 4" pvc pipe from freezing?
Document: This is my second attempt at trying to keep a water pipe connected to an outdoor faucet from freezing. The first was an earlier EasyHeat heating cable version that required assembly and had no built-in thermostat. It basically was a failure since assembly was difficult and once I got it to heat it went to over 80 degrees all the time.This M-D heating cable actually works correctly and requires no assembly.
I installed this tape two years ago to keep my pipe from freezing under our manufactured home in the chilly winter Cascade Mountains. It's performed with no problems. I like that it has a test light attached for piece of mind that it's operating. I had another heat tape before that failed in mid winter and the pipes froze. It is recommended to change out any heat tape every two to three years and inspect yearly.
I got this heating cable to use in an off-grid chicken coop to keep the water pipe from freezing. The heating cable appears to be a quality product, but it doesn't work with the rechargeable power supply I bought to use with it because the power supply is inadequate for the task. I have not, therefore, had a chance to evaluate the actual performance of the heating cable but it looks like a much higher quality cable than other heating cables I have purchased in the past.
These are only 12 watts. I wanted them to help keep my 2 citrus trees from freezing during light frosts. They're probably perfect for pipes. In tree branches, you can't even detect warmth with your fngers. The fruit hasn't frozen, so maybe they work for this application.
I ordered this to keep the pipes on our external water heater from freezing. We live in Dallas, so it normally isn't an issue, but this winter has been extra cold. Got it in three days ago and installed it right away. For the last two days, the pipes have been frozen in the morning. We've had to thaw them out with a space heater. I'll be looking for a full refund.
OK, the winter cold has set records all over the US.Record cold means bursted pipes, pipes which have worked for decades. Oh well. What is needed is something to keep these pipes heaters to keep these pipes from freezing. I do not know how good these heater ribbons work, I just buy them and give them as gifts to relatives and friends that have frozen pipes. They seem to work quite well, no complaints yet. The thermostat is a good plus.
This kept the water hydrant in my barn from freezing, just like it was supposed too. I know the hydrant is supposed to be anti-freeze, but the valve at the bottom was not working properly and water was sitting about in the pipe. During the cold nights it would freeze. This was a cheap and easy solution and it worked all winter.
I have baseboard (water pipe) heat for my house in northern Maine.My basement froze up when we hit below 20 suddenly one night. Whenever there are pipes near a wall in the basement and it is not insulated, there is a chance of these pipes freezing, especially if a little air seeps through.Solution:  Put this piping on.
This product is perfect for those that have exposed pipes that could potentially freeze. With the included thermostat, you never have to worry about it again. The pvc/vinyl coating is thick and provides good insulation on the wire.
Used this as part of my winter water hose for my RV. Even though it states not to use on waterhoses, I used this and a 30 footer on a commercial grade, drinking water approved, 50' 3/4 water hose. I can attest that it works down to 20 Deg F.
