How to Image for Pipe Freeze Protection
How to Prevent Residential and Commercial Pipes from Freezing

Internal water and sewer pipe heaters work by warming from the inside of the pipe, as opposed to heat tape or heat cords which wrap around the outside of the pipe.

Internal pipe heaters are especially useful for existing water or sewer pipes that are already under ground or enclosed in walls. Because internal pipe heaters generally install through a clean-out or gland, there is no need for expensive demolition and repair of walls or excavating and repair of driveways and lawns.

Depending on which internal pipe heater you choose, the diameter of pipe an internal pipe heater can protect ranges from ½″ to 2″.

Internal pipe heaters generally operate from 1 Watt/ft. in 120 Volt services up to 10 Watts/ft. depending on the make and model.

Water and sewer pipes should be clear and open from the main water source or sewer main into the warmth of the building. Internal pipe heaters cannot be installed if the pipe is already frozen. If your pipe is frozen, you’ll have to thaw the pipe before installing an internal pipe heater.

Once you’ve cleared the pipe or made the decision to install an internal pipe heater before your area freezes, it’s important to choose the internal pipe heater that works for your situation.
