How Heating Systems Work
The Problem
Thermal insulation alone will not prevent water pipes from freezing. For example, a ¾ in/1.91 cm pipe having 1 in/25 mm thick insulation
will freeze solid in only 13 hours when the ambient temperature is at 14°F/-10°C. Frozen water pipes can burst, causing loss of supply,
flooding and extensive damage.
The Solution
The Prime Pipe Freeze Protection Cable (pipe heating cable) replaces heat lost through the thermal insulation layer. Replacing the lost
heat allows the pipe and water inside the pipe to be kept at a constant temperature. With a built-in bi-metallic thermal cutoff inside the
black cap, the heating cable is operating only when the ambient temperature is 40°F/4°C or less, preventing unnecessary waste in
electricity, while keeping pipes protected all winter long. Plus, the Primelight ® indicator light illuminates to show power is being
supplied to the cable even when not heating; this allows you to check the status of the pipe cable at any time, even when it is not cold
enough to trigger the thermal cutoff.
Prime Water Pipe Freeze Protection Application
When installed correctly, the heating cable will be applied straight along the pipe with a single layer of fiberglass insulation to protect
pipes up to 1.5in/3.8cm in diameter down to -40°F/-40°C.
Prime Pipe Freeze protection systems are approved and qualified for the applications of freeze protection of insulated metallic or plastic
general water piping at the generally accepted maintenance temperature of 40°F/4°C.
Warnings:
!
(This symbol identifies particularly important safety warnings that must be followed. Failure to do so could cause
overheating and result in serious fire hazard or electrical shock)
• Do not use heating cable on pipes heated above 150°F/65°C (such as steam lines).
• Never install heating cable in walls, floors or ceilings.
• Never install heating cable on a plastic pipe unless the pipe is filled with water at all times.
• Do not use on waste lines, drain lines, fuel lines or hoses.
• Do not use pipe-heating cable for roof and gutter deicing applications.
