XAREX XGR 120V 117ft, Roof De-Icing Cable with Roof Clips and Downspout Hangers, Self Regulating Pre-Assembled Heat Tape with 120V 12ft Cord & Lighted Plug for Ice Dam Prevention Electric Heat Trace

Please accept our thanks for your interest in the 133ft XGR This is who we are - In most cases, heating cable that is used for roofing materials is safe. *br>In order to find out the temperature index of your roof's material, you will need to do some research. The cable we use for heating is T-shaped This means the cable is rated 6 so that its sheath (outermost surface) does not exceed 85 degrees Celsius. If your roof material can withstand temperatures up to 85C, you will be able to use our heating cable without any problems. I would like to express my sincere gratitude to you and Xarex

Xarex XGR should come with self-standing instructions. Thank you for writing. The PTC characteristic is regulated in a way that will reduce the heat output of the cable when it gets hot outside, thus preventing overheating or high electric bills. Nevertheless, we would like to recommend switching it off after every winter and turning it back on before the next one. It is recommended that you contact professionals to install thermostats and controllers if you would like to try them. The best way to maintain the life expectancy of our products is to turn them On and Off manually, but there are some wonderful (expensive) controllers, so do it at your own I have the pleasure of serving you, Xarex

We recommend that two lines of heat cables in gutters be placed horizontally in gutters for greatest performance. It is okay to cross over and to double up in certain places, but please keep them spaced apart to ensure optimal

In order to energize the heating cable beforehand (before icing conditions develop at the start of winter), the following needs to be done We seem to become energised once icing conditions have been cleared (in Our 87' heating cable has 7W/ft of power using the XGR 2000, however, the power increases to 13W/ft when the cable is wet (ice/snow surrounding cable), assuming ambient temperature is 32 degrees F. As such, our 87ft heating cable has a nominal wattage of 609 Watts in dry conditions, and as high as 1,131 Watts in wet conditions (ice and snow) when the outside temperature If the cable is energized below 32 degrees Fahrenheit, the wattage will be higher, therefore the current draw will be greater. In this case, all nominal values are based on 120VAC supply voltage, so the desired current draw can be calculated by dividing the power output (Wattage) *br>We also wish to point out that self-promotion is necessary for success The heating cable has an in-built thermostat that allows it to be controlled The current is typically 2 to 3 amperes in rush The current is drawn 3 times more than when it is energized, and it stabilizes at the normal current draw (nominal wattage) within Please let me know if this is helpful in answering I would like to express my sincere gratitude to you and Xarex
