You must cover pipe, freeze prevention, cable with insulation under all circumstances. Otherwise it will likely fail to do its job. This includes both Pipe Freeze Pro and Heat Tape Pro.
Use a minimum 1/2″ thickness standard pipe insulation.
Measuring the area of your roof that is affected by ice dams so you know how much heat tape to get is not overly complex, but it does have a few variables. Use our Heat Tape Measuring Guide to understand the process and print a worksheet that you can use to make sure you have all the right numbers.
Once you have all the measurements and considerations you need, use our Heat Tape Calculator to calculate the size of heat tape you should get.
PipeFreezePRO comes with one or more 30ft rolls of high-quality fiberglass tape, but you can use any tape with a temperature rating of 150º F and above. Self-adhesive aluminum foil tape can be used but avoid standard tapes, including electrical tape and duct tape because they lose their adhesion when exposed to heat. Remember, it’s imperative to cover the pipe/heat tape assembly with pipe insulation (1/2″ minimum thickness). Think four easy steps: 1) cable on pipe, 2) tape on cable, 3) insulation on pipe/cable and 4) tape on insulation.
Heat Tape Pro & Piper Freeze Pro can both overlap and/or touch itself in your installation.
It’s fine to overlap your heat tape pro, or have it touching itself in your install. The cable only itself heats up to less than 100ºF at most. This is plenty of warmth to stop ice dams from forming, but isn’t that much warmer than the temperature of your body. Sometimes it won’t even feel that warm to the touch.
This is different than a lot of heat tape that can be purchased at stores: contestant wattage cable can get much hotter and can even be dangerous if you overlap them. Not our cable, however.
Pipe Freeze Pro can touch itself, overlap with itself, or be wrapped around itself on the pipe. It won’t get too hot because not only is it designed to have a maximum output temperature that is less than 100ºF, it is self-regulating –so it’s output adjusts to the ambient temperature near the cable.
Radiant Solutions Self-Regulating Heat Tape changes its heat output based on the temperatures of its surrounding environment. At any given point, depending on the temperatures outside, the cable could be a range of temperatures. However, its peak temperature is not very hot –typically between 60º-85º when operating in a cool environment. Another way to think about it is that as long as the cable is above freezing it will do its job, which is to create and maintain melted pathways through snow and ice.
This gives our Heat Tape a great advantage over the heat tape you can buy in ‘Big Box’ retailers, because it creates enough warmth to effectively do its job, but won’t do damage to surfaces that it touches. Additionally, our heat cable can be overlapped without concern. Heat Tape that is not self-regulating (i.e., ‘constant wattage’) can not do this (they have explicit warnings in the directions not to do this for risk of fire).
We have even witnessed a coil of crappy big box heat tape starting a fire because it got plugged in when it was still coiled. (Yikes!)
The amount of heat cable needed for pipe freeze prevention is determined by a couple of simple factors including: Length of pipe, diameter of pipe, distance to power supply and number of valves.
Most of the time, we do not recommend a spiral cable application because it’s simply not necessary. It requires 3x the cable to do the same job.
Therefore, simply use a straight, single run of cable affixed to the bottom of the pipe (think 6 o’clock position) using the provided fiberglass installation tape. Next, add 1 foot of cable for every valve because you will be wrapping the valve with cable. For pipes less than 1″ in diameter, a single cable run is sufficient. For larger pipes, two cable runs are recommended. Keep in mind that plastic pipes are less thermally conductive so you may choose to use two cable runs on larger plastic pipes to be safe. Finally, if your outlet isn’t close to the pipe you are treating, factor in enough heat cable to reach your outlet (Pipe Freeze PRO does come with a 36″ power cord).
Finally, you must install insulation on your pipe and heat cable assembly in order for the system to operate effectively. See instructions for further details.
