What causes water pipes to freeze?
Water pipes freeze when the ambient temperature of the pipe drops below 32°F or 0°C.
At that temperature, water in the pipe begins to freeze and build up in the pipe causing a blockage. As the ice begins to expand, unfrozen water is forced into smaller and smaller areas in the pipe.
This causes enormous amounts of pressure to build up inside the pipe. As the ice continues to accumulate it can generate over 2,000lbs. of pressure inside the pipe, eventually forcing the pipe to burst.
But when pipes burst it's not caused directly by the ice swelling. The rupture is caused by the pressure from the unfrozen water between the ice and the closed faucet.
That's why ruptured water pipes cause so much damage and are so expensive to fix.
How do HotLine™ Internal Water Pipe Heaters work?
HotLine Internal Water Pipe Heaters work by protecting your pipe from freezing before a freeze ever occurs.
If you've previously had water line freeze problems, just install a HotLine Internal Water Pipe Heater before cold weather sets in.
If you're already frozen, thaw your water pipe and immediately install a HotLine the entire length of the pipe. Your HotLine will warm the water line from inside the water pipe and keep it from freezing all winter long.
And, because HotLine delivers the heat to the inside of the water line, most installations do not require digging or excavating (like common heat tape products).
What is a HotLine™ Internal Water Pipe Heater?
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. Click or Tap here for HotLine voltage by length
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.
HotLine's low voltage makes it very economical to run. In fact, many people don't even notice a difference in their electric bill! Go here for HotLine's average cost breakdown
Requirements for successful installation and operation of your HotLine Internal Water Pipe Heater are:
- Accurate measurement of the entire line to be protected before ordering your HotLine Internal Water Pipe Heater! Go here for complete HotLine Measurement Instructions
- Water line should be clear and open the entire length of the pipe;
- HotLine requires a minimum 1⁄2″ pipe and works in all standard diameter water pipes;
- The pipe should have long sweeping bends with a minimum radius of 4″ diameter bends to facilitate the entrance of the HotLine element inside the pipe.
HotLine installs directly into your water line up to 120 feet. And - unlike external heat tape - there's No digging ... No wrapping ... and No problem!
If you're handy you can install HotLine yourself or call your plumber or local handyman.
