The HotLine Internal Water and Sewer Pipe Heater works by warming your incoming and outgoing water lines as well as outgoing sewer lines from inside the pipes to keep them from freezing.
Unlike other pipe heating or heat tape products, HotLine delivers the heat to the inside of the water or sewer line, not the outside.
HotLine's heating element consists of a modern alloy, insulated resistance wire, encased in a copper or plastic tube for protection.
HotLine Internal Pipe Heaters are made from food-safe, FDA and EU approved Hytrel™ by Dupont.
The HotLine heating element operates on 6 to 32 Volts of AC power, according to the length of the heating element:
There is no electrical shock danger, unlike other 120 volt heating devices. In fact, HotLine's voltages are similar to those used by most common model railroad trains.
The HotLine power center box contains an indicator light and a fuse-protected, step-down transformer.
The transformer operates on a 120 Volt, 15 Amp circuit, and provides low voltage (6 to 32 Volts) output to the HotLine heating element.
For HotLine to work successfully, the incoming water or sewer line should be clear and open from the main water source or sewer main and into the warmth of the building.
HotLine requires the incoming water and sewer lines to be a minimum of 1/2 inch pipe.
The pipe should have long sweeping bends with a minimum radius of 4 inches diameter bends to facilitate the entrance of the HotLine element inside the pipe.
HotLine installs directly into the water or sewer line, up to 120 feet. And - unlike external heat tape - in most installations you won't have to dig or wrap!
If you're handy you can install HotLine yourself, call your plumber, or your local handyman.
