Quick Answer: Should Heat Tape Feel Warm To Touch?

What is self regulating heat tape?

Self-Regulating Heating Cables Self-regulating / self-limiting heating cable, often called heat trace cable or heating tape, automatically adjusts heat output based on surface temperature.

Ideal for freeze protection and low temperature process maintenance such as water pipe heating and roof & gutter freeze protection..

What temperature does heat tape come on?

Heat tapes come in many various lengths and manufactures. The better quality tapes use a thermal sensor embedded in the tape to turn on the heating process once the temperature drops to around 38 degrees F (2 degrees C). Manufacturers instructions are provided on the package on how to properly install the tape.

Can you wrap heat tape with insulation?

Don’t cover heat tapes with insulation even if the tape manufacturer permits it. If you do add insulation, only use fiberglass or another non-flammable material. Do not use foam or vinyl insulation as they could catch fire easier. Do not wrap heat tape over itself even if some manufacturers allow it.

Can you spiral heat tape?

Heating tape can be installed on nearly any surface due to its flexibility. Spiral wrap the heating tape onto the surface to be heated so that the length of one entire side of the heating tape is in full contact with the surface (Figure B).

How long can you leave heat tape plugged in?

3 yearsSpeaking of replacing, heat tape only has a 3-year lifespan. Most heat tape manufacturers warn that you should replace your heat tapes every 3 years minimum. Heat tape has a near-constant connection with both water and electricity and usually isn’t protected well from the elements.

What if heat tape is too long?

1 Answer. Usually you can wrap the tape around the pipe as you install it. You can then add or subtract wraps to adjust the length and make it come out where you want. This works well for just a short amount of slack.

Will heat tape melt hose?

Make sure that the heat tape does not overlap itself. This can cause hot spots that will melt the hose as well as the heat tape’s plastic sheath. You should use only tape commonly referred to as electrician’s tape, to hold the heat tape to the hose.

How many amps does heat tape draw?

How do you troubleshoot a heat trace?

When circuit temperatures are too high and cause problems in your heat tracing system, consider these possible causes:incorrect setpoint on the thermostat or process controller.incorrect location of the temperature sensor.incorrect wiring of the temperature sensor.a faulty thermostat.

Can heat trace touch itself?

CAUTION: For series constant-watt trace heaters (HTEK, TEK, TESH), do not allow the heating portion of the trace heater to touch, cross over, or overlap itself.

When should heat tape be turned on?

The cables should be turned on when snow is expected – perhaps an hour or two before snow starts falling.

Does heat tape cause fires?

Sadly, heat tape has the potential to cause fires in homes and businesses. Many of these products consist only of non-regulating tape which plugs into a wall outlet. If the heat tape remains activated for long periods of time – especially if temperatures rise and/or the tape is well-insulated – it can spark a fire.

Can you leave heat tape plugged in?

Modern tapes have a built-in thermostat that automatically calls for power (and the resulting heat) as the surrounding temperature drops near freezing and cuts power off as the temperature rises. Those tapes do not draw electricity all the time, even though they remain plugged in.

Does heat tape use a lot of electricity?

Typical heat tape burns electricity at six to nine watts per foot per hour. That means each 100 feet of heat tape operating 24/7 can translate to an added monthly cost of $41 to $62 to operate heat tape, says Eileen Wysocki, energy auditor for Holy Cross Energy.
