Does self-regulating heat trace need a controller?

Does self-regulating heat trace need a thermostat? Although it’s called “self-regulating,” the cable will not turn itself completely on or off. So, we do recommend that a controller or thermostat of some sort to be used with this type of heating wire.

Can you cross self-regulating heat trace?

Constant wattage heat trace and MI cable cannot cross or touch itself. Self-regulating heat trace cables, however, would adjust to this temperature increase, making them safe to cross or overlap.

Can you use electrical tape on heat trace?

You can use any tape with a minimum temperature rating of 176º F, with fiberglass cloth tape being the most common. Standard tape, including electrical tape and duct tape, lose their adhesion when exposed to the heat generated by pipe trace heat cables over time.

Can heat trace be submerged?

Heating cord Available with housing styles that are resistant to water and many chemicals, and suitable for outdoor use. Some styles are resistant to moisture or suitable for use on electrically conductive surfaces, but they must not be submerged, and are generally intended for indoor applications.

What is the difference between self-regulating and constant wattage heat trace?

Pipe trace constant wattage has a higher temperature output and tolerance. It consumes more power so it requires a controller or thermostat and some types can be cut-to-length. Self-regulating cables have a lower temperature output and tolerance. They consume less power, but require larger breakers.

What is constant wattage heat trace?

Cable This style of heat trace cable is designed to put out a certain amount of wattage per linear foot at a particular voltage. It is always putting out the designed watts per foot, no matter what the surface or ambient temperature is.

Can you leave heat tape plugged in?

When the temperature drops, a small thermostat (built in on most models) calls for power that produces heat, then cuts off power after the temperature rises. You can leave these models plugged in. The Consumer Product Safety Commission (CPSC) says they no longer collect data on heat tape-related accidents.

Does heat trace need to be insulated?

If you can see the pipe at any point it MUST be insulated. Wind-chill and extreme cold ambient temperatures are the main factors that lead to heat loss, causing your pipe to freeze even when protected by heat trace. Being in a boxed enclosure or big-o drain pipe is not enough protection, it must be insulated.

When should heat tape be turned on?

Self-regulated heat tapes don’t get very hot at all which is why they aren’t helpful to unfreeze pipes. In fact, they should be installed on your pipes long before the first freeze. The new self-regulated heat tapes will turn on when the temperature gets below 40 to 38 degrees.

How does a 3m heat tracing cable work?

Heating Cables 3M Self-Regulating Heat Tracing Cables consist of a conductive-polymer heating matrix between two parallel bus conductors. Therefore the cable can be cut to any desired length without changing its properties. The heating matrix provides an infinite number of parallel resistances.
