What voltage is this?

Why is it not advised to use the heat cable on a pvc condensate drain pipe?

Can the heat cable be used as a short-term solution to defrost a pipe. I.e. only turn on the cable when the pipe is freezing. Thanks.
Asked by: customer01
Hi customer01 - the pipe must have water in it at all times so the cable doesn't overheat and melt your pipe. Drain pipes will not have water in them all the time. Phone Frost King 1 800 562-6587 M-F 8 am - 5 pm for more information.

Is the cable OK to use on the PVC drain pipe from a condensate pump reservoir. The water flow is intermittent.

Asked by: Blackrock41
This cable will not heat the water in a pipe, even when the water doesn't flow for long periods. It isn't a water heater, it is more like a trickle heater that comes on and off by the thermostat, and it does NOT measure or monitor the temperature of the water, it monitors ambient temperature where the thermostat is located in the cord. It would likely never damage an empty pipe but the manufacturer will certainly not recommend using it for that purpose because that makes them liable, and we all know anything can happen. They will only state what they can regulate and be responsible for. Think of it as an electric blanket, it doesn't get hotter and hotter until the water heats up or boils, it only heats enough to keep it from freezing.

After ran & secured the cable paralle to the pipe, can we wrap it with the foam insulation tube ?

Asked by: Barry
I prefer the foam rubber tubes over fiberglass wrap, but I use a size larger than the pipe and I use the ones for refrigerant lines because the can handle more heat, aren't as cellular and are made for exterior use.

6 ft. Electric Water Pipe Heat Cable is rated 4.2 out of 5 by 38.
Rated 3 out of 5 by from Works Used this to wrap a back flow for the sprinklers system during a late spring freeze. I did over lay it with a sheet and then a shower curtain to stop snow from getting to the heat tape and cord. Worked very well. Keep in mind it has a thermostat so it will only heat bellow freezing

Rated 3 out of 5 by from I recently (10/2016) purchased this cable in order to prevent two water pipes in an exterior wall... I recently (10/2016) purchased this cable in order to prevent two water pipes in an exterior wall from freezing as they have sometimes done in the past. In the last year I also installed pipe insulation however I didn't open the entire wall so I don't know how well insulated the pipe really is. The entire cable is very robust and quite thick and appears very well made. The cable is sold in several lengths and the instructions state that one cable should only be used on 1 pipe because of the risk of overheating. I purchased the 6 ft cable but after reading the instructions thought I should have two 3 ft cables instead. I didn't find any 3 ft cables for sale at HD or other stores so I installed the 6 ft cable anyway. This was the first of several installation problems. You are instructed NOT to install the cable inside a wall so I was restricted to the exposed cellar pipes. Next the instruction say to position the thermostat so that its disk is touching the pipe. As the disk is flat and the pipe is round it does NOT hug the pipe very well. As the disk is close to the plug it was difficult to position the disk because the cord was pressing against the subfloor above and only has limited flexibility. The thermostat will only trigger to go On at 38 degrees F or lower. Since my pipe is a long vertical run (25') I'm hoping that the freezing water will descend in the pipe and trigger the thermostat to go On and begin heating the cable and the water inside before the water at the top of the pipe freezes. Since the pipes run through the cellar those parts are not subject to freezing so I'm uncertain if this cable will actually trigger to start heating. The plug is equipped with an LED so you can determine if the unit is drawing power however as soon as you plug it in the light goes on so apparently the thermostat is drawing some power. What I need to know is if it is cold enough to trigger the cable to heat. I'll have to touch it to find out if the cable is heating. Because of the location of the two pipes I extended the one cable onto the other pipe for a short distance. The Cable has a strange square knob at its end which the instructions say nothing about. I'm hoping that this is simply some type of terminating feature and is not some other thermostat that might control the heating cable temperature. The plug comes with a warning label on it stating that GFCI MUST be used however the instructions contradict that and only recommend that a GFCI be used. The unit is sold without Insulation but the instructions recommend using Fiberglass wrap insulation followed by plastic wrap. That was another $6.50. I'm hoping that the insulation will help prevent the pipe from gaining too much warmth from the cellar to increase the likelihood of triggering ON. You are instructed NOT to have any part of the heating cable crossing or touching any other part nor are you to twist the cable around the pipe in a spiral. The cable can be doubled back on the side opposite if needed. On a small pipe in tight quarters all this cable is somewhat cumbersome. What I was really looking for was a low-cost heating element that I could position on or near the pipes that would constantly heat to a set temperature or with a variable temperature control. Last year I was using a light bulb however that isn't feasible this year. I did not find any other products at HD or online that serve this purpose. I won't know if this product helps me until further into the winter. Yet another maintenance item to keep track of in this old house.
