Quick Answer: How Does Heat Tape Work On Pipes?

Can I put pipe insulation over heat tape?

Do not install heat tape around pipe insulation – only the pipe itself.

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..

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.

What can I do with excess heat tape?

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.

Do plumbers install heat tape?

Most plumbers don’t like heat tapes–those cables that look like extension cords but generate heat to keep pipes from freezing. … 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.

How many amps does heat tape use?

0.2 AmpProven low-wattage design uses up to 65 percent less energy at 2 watts per foot vs. other cables at 7 watts per foot, and protects to -50ºF.

Can heat tape cause a fire?

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.

What is the best heat tape for water pipes?

Heat tapeSilicone rubber heat tapes are a good heat tape for applications up to 450°F, and are chemical- and moisture-resistant. ( … Fiberglass-insulated heat tapes come without controls – no built-in thermostat.More items…

Is heat tape expensive to use?

Second, not all types of heat tape can be used on plastic pipes because they may cause them to melt. Finally, they cost money to run, which is especially problematic in areas with high electrical costs. For example, heat tape may draw 5 watts of electricity per foot.

Do you insulate hot or cold water pipes?

Both hot- and cold-water pipes should be insulated when the goal is preventing freezing. If the goal is to lower water-heating costs, then it’s wise to insulate hot water pipes wherever you have access to them.

Does pipe wrap insulation work?

Insulating your hot water pipes reduces heat loss and can raise water temperature 2°F–4°F hotter than uninsulated pipes can deliver, allowing you to lower your water temperature setting. … Paying for someone to insulate your pipes—as a project on its own—may not make economic sense.

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 plug heat tape into an extension cord?

Don’t forget to plug in your heat tape before the onset of cold weather. Do not use an extension cord. The heat tape must plug directly into a Ground Fault Circuit Interrupter (GFCI) receptacle. You should find a GFCI protected outlet underneath your manufactured home, near the water inlet.

Does heat reflective tape work?

Reflective tape is useless to stop radiation heat unless you can create a dead air layer between the tape and some other surface. That’s how the radiant heat barrier works. If you simply wrap something with this tape and it is in direct contact with any surface, it will have very little effect if any.

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.
