how much power does a heat tape use

by Sylvia Morissette V Published 3 years ago Updated 2 years ago

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.

Full Answer

How much heat tape do I need to run a thermostat?

Use the 3" tape at 4 watts per foot and that same 500 watt thermostat will run 90 feet total, a 1000 watt thermostat about 180 feet total. The 4" heat tape is 6 watts per foot and we recommend no more than 80 feet and 160 feet total respectively.

How do I choose the best heat tape?

Consider a heat tape kit: In addition to the raw heat cable that is sold by the foot and fitted with plugs, you can also buy heat tape kits in just about any length you might need—from 3 feet to 100 feet. These tapes have plugs already attached and usually have a power indicator light that indicates when the tape is actively heating.

What is the maximum length of heat tape?

It is recommended you keep your heat tape runs at a maximum length of under 50 feet in length for the 3 and 4 heat tape, under 35 feet for the 6 heat tape and under 25 feet when using the 12 heat tape. Remember- these are considered maximums, it is wise to stay below them.

What is heat tape and how does it work?

Strouse has highlighted a form of electrical tape called ‘heat tape’ that can prevent ice from accumulating on your roof. However, When people discuss heat-resistant tape, they immediately think about vinyl tapes, and for good reason. The premium vinyl tape has multiple half-lapped layers that guarantee enhanced electrical insulation.

How many amps does a heat tape draw?

All of the Automatic Electric Heat Cable Kits (3 feet through 30 feet) carry a rating of 120V, 7 Watts per foot with a maximum draw of 15 Amps.

How much does it cost to run roof heat tape?

Does heat tape use a lot of electricity? The average heat tape uses electricity at six to nine watts per foot per hour. So, if you have 100 feet of heat tape that operates 24/7, you can expect to add about $41 to $62 to your monthly electricity bill.

Can you leave heat tape plugged in?

You plug one end into an outlet and spiral wrap the rest around a water pipe, or drape it along a gutter or roof edge. 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.

Does heat tape require electricity?

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 roof heat tape use a lot of electricity?

Invest in a heat tape timer to minimize energy use 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.

When should I turn on my heat tape?

The cables should be turned on when snow is expected - perhaps an hour or two before snow starts falling. This is true for both the zig zag style of installation or when radiant roof panels are used. The roof heat cables should be warm to start melting immediately when snow is falling.

Can pipes freeze with heat tape?

Heat tape prevents pipes from freezing and bursting, which can save you from expensive repairs and damage to property.

Can I use an extension cord for heat tape?

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. If not, you will need to install one.

At what temp does heat tape stop working?

Best Heat Tape for PVC Pipe Most PVC plumbing pipe can safely withstand temperatures between 140-160 degrees without fear of melting.

Will heat tape thaw frozen pipes?

You could also purchase some heat tape, sometimes called heat cable, from your local hardware store. Simply wrap it around the pipe evenly and plug it in. The cable will warm up the pipe and thaw the frozen ice. Apply heat until the water flow is restored.

Which is better heat tape or heat cable?

Heat trace cable is somewhat stiff, but it's pliable enough to wrap it around your pipes, and it does not shrink; Heating tape is extremely flexible, therefore it's better for tight contours and oddly shaped pipes.

Can you wrap PVC pipe with heat tape?

Yes. Pipe Freeze PRO heat tape can be used on all varieties of pipes including PEX, ABS, PVC, Nylon, Steel, Copper and more.

How long should heat tape be?

It is recommended you keep your heat tape runs at a maximum length of under 40 feet in length for the 3", 4" and 6" heat tape, under 25 feet when using the 12" heat tape and under 10 feet for the 21" heat tape. Remember- these are considered maximums, it is wise to stay below them.

What is heat tape?

Heat tape is a thin laminate material that can be cut with any good quality scissor. The element that we sell has been specifically chosen for reptile rack and cage use and can be cut to almost any length. MAKE SURE THE ELEMENT IS UNPLUGGED WHEN TRIMMING! Sorry, I had to say it.

Why is my heat tape not getting hot?

Because you are not really sure how hot your heat tape is really getting, especially in a cooler room. With the probe on the heat tape you KNOW that your heat tapes actual temp is controlled. If you still can't get up to temperature then you need to consider a warmer room.

How many watts per foot for a 500 watt thermostat?

Use the 3" tape at 4 watts per foot and that same 500 watt thermostat will run 90 feet total, a 1000 watt thermostat about 180 feet total. The 4" heat tape is 6 watts per foot and we recommend no more than 80 feet and 160 feet total respectively.

What is a THG element?

The THG element was designed for reptile use from the start, unlike others that are crossovers from the floor heating industry. Along each side of the heat tape is a copper foil strip that conducts electricity to the black lines in the tape that make up the heating element.

Does the belly heat rack know the temperature?

But if I place the probe on the heat tape with my belly heat rack I won't know the temp in the tub, Right? Yes and no. True, your thermostat will not know the temp in the tub over the heat tape (basking area) but you will. Generally the heat tape will be warmer than the temperature in the tub.

Do I need a thermostat for heat tape?

Do I really need to use a thermostat? In a word, YES! Heat tape will last much longer and be much safer for you and your animals if it is used properly and safely. The manufacturer of heat tape indicates it should never be used without a thermostat or rheostat to control its temperature.

How long is a heat tape?

Consider a heat tape kit: In addition to the raw heat cable that is sold by the foot and fitted with plugs, you can also buy heat tape kits in just about any length you might need—from 3 feet to 100 feet.

How do heated water hoses work?

Heated hoses come in many lengths and are designed with electrical conducting wires embedded into the rubber or vinyl walls of the hose. When these hoses are plugged in, electrical current heats the hose all the way to the end. These hoses shut off automatically in warm weather to save on electricity and prevent overheating.

Can heat tape be used on pipe?

Many types of heat tape are just attached to the underside of the pipe and can be attached to the pipe with electrical tape or zip ties. Other types are designed to be wrapped around the pipe in a spiral fashion, and some can be installed either way. Do not overlap the tape unless the manufacturer specifies that this is acceptable.

Can heating tape be cut?

The heating tape can also be custom fit to your application because it can be cut to any size that is needed; plugs are then added to the ends of the cable. Thermostat-controlled heating tape is also available in kit form in various lengths with the plug and thermostat already attached.

Can you insulate pipes from freezing?

Insulating your pipes is essential and will prevent pipes from freezing in many situations, but it is not always enough when the temperatures stay cold for days at a time or when temps plummet into the sub-zero range. This is where electric heat solutions come in handy.

Can heat tape be covered with insulation?

However, read the package directions carefully to make sure that the heat tape can be covered with insulation. And make sure the thermostat is in the coldest area and directly on the water pipe itself to give an accurate reading.

Can heat tape be used on metal water lines?

Most heat tapes are approved for use on either plastic or metal water lines, but it is best to make sure that this is the case before you buy. Also, make sure it has the features you want, such as a power indicator light and a built-in thermostat.
