【Ultra-high Heating Efficiency】: The heat tape can withstand -40°F cold weather. Unlike ordinary heating tapes on the market, after thousands of experiments by a team of doctoral researchers in a German laboratory, the factory finally chose 18W/FT. The addition of a thickened copper wire core brings dual benefits of heating efficiency and energy-saving experience, which is the most important reason why customers have chosen SZFY over the years. 【 Durable and Sturdy 】: The heating tape is made of multiple layers of rubber wrapped around thick copper wires, and its normal service life can reach 10 years. The difference between the copper wire and the ordinary heating tape is that we use heating wire with a diameter twice that of the market, which makes the heat conduction effect of the product better. 【 Wide Application 】: 3-50FT. We are equipped with tape to enable the heating cables to be better wrapped around the water pipe. We have equipped 80FT-200FT with tape and roof fixing accessories to increase the roof installation scenarios. In any case, using heating tape on farms, chicken coops, stable sheds, and palm trees is also a choice for many people. Let your imagination run wild and solve all the freezing problems you encounter in winter! 【 Flat Design 】:Unlike the heating tapes on the market that have a round cross-section, our new type of heating tape can better fit the object itself, whether it is a water pipe or other objects that need to be heated. It has a larger heating area and can better play the role of a heating wire. 【Service Upgrade】Our professional customer service department will make every effort to ensure your satisfaction, 30-day money-back and 1-year water line heat tape offering.
