Determining the length of Tandem-Link that you need to fit application is very simple as the Tandem-Link system is designed to run straight along the pipe in most applications depending on pipe diameter and insulation thickness. When in doubt, order longer than expected.

To freeze protect small diameter pipes of  2 in. (51mm) inside diameter (ID) or less a single trace of heater is often enough; however in extreme cold application more insulation and or passes of heater may be required. Increasing your thickness of insulation can also minimize the require amount of Tandem-Link heating cable and vastly increases your energy efficiency.

For pipe diameters greater than 2 in. (51mm) in diameter a minimum of 2 traces of heating cable is recommended and a consultation with a Heat-Line application specialist is suggested to ensure proper performance.

If you have any specific questions regarding the required lengths of Tandem-Link for your parameters please call Heat-Line directly and speak with one of our Heat-Line application specialist. Have the following information available if possible:

  • Pipe Type (Metallic/ Non-metallic)
  • Pipe Diameter
  • Pipe Length
  • Minimum Ambient Temperature
  • Number of valves and or spigots located along the pipe
  • Thickness of Insulation (Heat-Line offers a variety of insulation to meet application requirements)

INSULATION

Insulation is recommended for all new pipe installations, even where the pipe is to be buried. For existing pipe applications, insulation is only required where the pipe is exposed to ambient outdoor temperatures, and/or where the pipe is above the ground. Insulation aids in heat retention making the heating cable more energy efficient and providing cold weather reliability.

THERMOSTATS

Thermostats are not required to operate the Tandem-Link system as they are assembled with Heat-Line’s advanced self-regulating heating cables and do not require a high limit protection device. A thermostat however can be added to duty cycle the heating cable in an on/off operation saving power consumption.

Click here for thermostats.

TIMERS

Similar to thermostats, timers are not required to operate the Tandem-Link system as they are assembled with Heat-Line’s advanced self-regulating heating cables. A timer however can be added to increase your energy efficiency as the system will duty cycle based on the preset inputs.

MILLIAMP GFCI Device

According to the Canadian and National Electrical Codes all heating cable systems are required to be protected by a GFCI device for safe operation. All GFC model heating cable systems manufactured by Heat-Line are supplied with a 27 milliamp GFCI. In applications where a hard-wired or CS model Tandem-Link is required, GFCI protection must be supplied and installed by the installing professional. For hard-wired or CS model installations Heat-Line offers the MilliAmp GFCI device, which is an external enclosure complete with a Class A certified GFCI for both 120 volt and 240 volt applications.

FOIL TAPE

When applying the heating cable to the outside of a pipe, it is beneficial to use a foil tape to increase your thermal transfer surface area. You can apply the tape to the pipe first, and then apply the heating cable to the pipe with the tape covering it. Applying insulation over is highly recommended, especially when the installation is above ground.

HLP-TAPE

HLP-TAPE is used to tape the butt-ends of the INSUL insulation sleeves together so they do not slide apart which would result in a cold spot in the pipe. 

CABLE GUARDS

Care should always be given to avoid damage to the heating cable during installation. In some applications abrasive edges may be present where the heating cable must travel. Cable guards can be installed over the heating cable providing mechanical protection when passing over abrasive areas.

Q - What is the difference between Tandem-Link and Paladin?

A – There is no operational difference between the Tandem-Link and Paladin heating cable. The Tandem-Link system is inter-connectable with a male plug on one end of the heating cable and a female plug on the opposite end. The Paladin system is complete with a male plug on one end, and an end seal termination boot on the opposite end.

Q - Is Tandem-Link safe to use on plastic pipes?

A- Yes. The Tandem-Link system is approved for use on all metallic and non-metallic pipe applications. The advance self-regulating technology employed in the Tandem-Link product renders it safe on plastic pipes even when dry as it can never overheat and damage the pipes.

Q - Can Tandem-Link be buried?

A – Yes. The Tandem-Link heating cable can be buried; however the plug ends should remain above the ground.

Q - Do I have to spiral the Tandem-Link system around the pipe or just run straight along the side of the pipe?

A - Since Tandem-Link has extraordinary heat transfer properties it can be simply run straight along the pipe without the need to pitch or spiral the heater on pipe diameters of 2’’ or less. For larger pipe dimeters multiple passes or spiraling of the heating cable may be required.

Q - Does the Tandem-Link come with a thermostat?

A – No. A thermostat is not included with the Tandem-Link product as they are not required for proper and safe operation; however a thermostat can be purchased as an additional accessory. Depending on system applications, or where automatic operation is preferred, a thermostat can be used to switch the system on and off to help conserve power or to duty cycle the system. When combined with insulation thermostats can substantially increase energy efficiency.

Q - What do I do if I have extra Tandem-Link heating cable?

A - If you have extra heater you can loop the excess back up the pipe or concentrate more heating cable in more exposed sections of the pipe. If needed it is safe for the heating cable to overlap as it is self-regulating and will not overheat.

Q - Does the unit shut off when not required?

A – No. Tandem-Link self-regulating heating cable systems increase heat output with cold but more importantly, decrease heat output with warmth. As a result, Heat-Line brand products are very energy efficient to operate, but do not completely shut off as they can only idle their output to a minimum amount. To completely shut off the system it must be unplugged or installed with a thermostat. Heat-Line brand systems should be unplugged or shut off when not required (summer months) and tested each year before use.

Q - Does a 240-volt system use less power than a 120-volt system?

A - No - Energy efficiency has nothing to do with the designated voltage. We pay for the energy in watts, not in volts. Years ago the term more efficient was attached to 240 volt systems because you can put more load or amperage on a 240 volt circuit. Unfortunately the term more efficient somehow became misinterpreted to mean more energy efficient which is not the case.

Q - How much power does a Tandem-Link unit consume?

A- All Heat-Line brand systems including Tandem-Link employ Heat-Line’s advanced self-regulating heating cable technology which operates to deliver energy and heat output to areas of the pipe that are cold and reduces energy and heat output to areas which are warm. While the overall amount of energy consumed depends on multiple factors you can be assured that you are installing the most energy efficient heating cable system available. If you would like to reduce your energy consumption further you can investigate the addition of a thermostat, timer, and or other control device.

Q- Is there a maximum length of Tandem-Link heating cable systems?

A – Yes. The maximum circuit length of Tandem-Link that is allowed is as follows:

Maximum length on a 120V circuit is 205ft. (62m) AND/OR 3 connected cables

Maximum length on a 240V circuit is 410 ft. (125m) AND/OR 3 connected cables

Q- What type of insulation should I use with the Tandem-Link system?

A – Heat-Line recommends to use insulation that is best suited to the environment in which it is going to be installed. A common type of insulation employed with Tandem-Link heating cables is fire resistance water proof pipe foam insulation sleeves. You are also able to implement fiberglass insulation provided it is properly weatherproofed based on the environment.

Q – Where do I purchase a Tandem-Link heating cable system?

A – The Tandem-Link heating cable system manufactured by Heat-Line is available directly through Heat-Line and or any of our Heat-Line product distributors. For a list of Heat-Line product distributors in Canada and the United States please contact Heat-Line directly on our toll free number at (800)854-4944.

Q – Do I have to use insulation with the Tandem-Link system?

A – Insulation is highly recommended when using the Tandem-Link system, especially if the installation is above ground in ambient outdoor air. Insulation helps reduce the overall heat loss and therefore reduce the amount of energy the Tandem-Link heating cable must consume. It also helps keep the heating cable in consistent contact with the pipe.
