HF7000 trace heating kits provide winter frost protection for pipes up to 100mm in diameter. The kits come complete with self-regulating trace heating cable, an ambient sensing control thermostat, and all necessary components for easy installation. The self-regulating cable automatically adjusts its heat output along its entire length in response to varying temperature conditions to protect pipes from freezing. The kits have been tested to provide reliable frost protection for over 40 years.
