Measuring Recommendations for Paladin for Pipe

Always measure prior to ordering, do not assume or estimate the length required.

-The Paladin for Pipe is an advanced external self-regulating heating cable system factory finished and supplied job-ready to a pre-determined length provided at the time of order.

-Paladin for Pipe systems are priced and manufactured in standard lengths of 10 ft. (3m) increments up to 120 ft. (36.5m) in 120 volt, and in 10 ft. (3m) increments from 10 ft. to 240 ft. (3m – 73m) in 240 volt.

Important Notes

-A Paladin system can never be lengthened. If a longer system is needed either a separate heating cable would need to be purchased to make up the difference or an entirely new system of the appropriate length.

-A Paladin system can never be cut shorter at the job-site. If a shorter system is needed it can be looped at the end, or spiralled back on the pipe. Unlike traditional heat tape system, It is safe for the Paladin self-regulating heating cable system to overlap.

-Given that Paladin for Pipe systems are provided in 10 ft. (3m) increments it is wise to always round up to the nearest standard length. For example, if an 18 ft. (5.5m) heating cable system was required, round up to a 20 ft. (6m) system.

External Applications

-When measuring the length required of an external pipe heater wire system, care is required to ensure that the ordered length is exact or longer than required. There is no way to lengthen the Paladin for Pipe product when on site.

-For the best results when calculating the required length of Paladin for Pipe that is required you should gather the following information:

  •  Pipe/ drain type/ material (PVC, Copper, PEX, ABS, Iron Pipe, Galvanized, etc.)
  •  Pipe/ drain diameter
  •  Pipe/ drain length
  •  Number of valves and or spigots along the length of the pipe
  •  Insulation type and thickness if applicable (Heat-Line can recommend insulation options)
  •  Lowest outdoor ambient temperature
  •  Is the pipe or drain buried or above ground

-Determining the length of Paladin heat trace required for common external heat tracing of metallic and non-metallic pipes could not be simpler as most pipe 2 inch (51mm) or less in diameter only requires a single (straight) trace of Paladin along the length of the pipe.

-For lengths of pipe that have spigots and or valves you will need to add at least 2.5 ft. (0.75m) of additional pipe warming wire per valve and or spigot.

-For special applications and or pipe diameters greater than 2 inches (51mm) contact Heat-Line and speak with an application specialist to determine exact requirements.

Internal Applications

-While the Paladin heated pipe wrap system is designed for external heat tracing of small and larger diameter metallic and non-metallic pipes, it can also be installed within gravity-fed ground water drains given its wet location approval.

– Determining the length of Paladin pipe warming wire required for internal heat tracing of metallic and non-metallic drains could not be simpler as the objective is to create a melt water pathway or channel within the larger drain.

-A common single (straight) internal length of the Paladin is all that is commonly required within a drain. In applications where the outlet of the drain is exposed, Heat-Line recommends to double back or dual trace the last 2-5 ft. (0.6m – 1.5m) of the drain.

Paladin is considered a stocked item with the most common lengths available ready to ship. For custom or non-stock orders, Paladin can generally be shipped out within 1-3 days from the time of order. Please call for current availability and lead times.

Paladin Product Code Guide

Paladin Product Code Guide

Q – What is the difference between Paladin and EXT-R Series?
A – There is no mechanical and or physical difference between the Paladin and EXT-R series product groups. The Paladin system though however carries an additional certification designation that the EXT-R does not which makes the Paladin product certified for use in Roof and Gutter de-icing applications.

Q – Is Paladin safe to use on plastic pipes?
A – Yes. The Paladin system is approved for use on all metallic and non-metallic pipe applications. The advanced self-regulating technology employed in the Paladin product renders it safe on plastic pipes even when dry as it can never overheat and damage the pipes.

Q – Can Paladin be buried?
A – Yes. The Paladin system (along with EXT-R and EXT-T) is certified for both direct burial and wet locations making the heating cable and proprietary end-seal termination completely safe to bury.

Q – Can Paladin only be used to trace pipes on the outside?
A – No. Paladin was originally intended to be installed on the outside of the pipes however because of its specialized wet location approval it is suitable to be placed inside non-pressurized, non-potable pipes such as drains.

Q – Do I have to spiral the Paladin system around the pipe or just run straight along the side of the pipe?
A – Since Paladin has extraordinary heat transfer properties it can be simply run straight along the pipe without the need to pitch or spiral the heater. This unique ability means that the overall length of heating cable required greatly reduced, decreasing overall operating costs.

Q – Does Paladin come with a thermostat?
A – A thermostat is not included with the Paladin 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 – Can I (the homeowner) install Paladin?
A – Heat-Line provides proper and easy to follow installation instructions with all of our products, and offers market-leading technical support. As a result, most Heat-Line systems, including Paladin can be installed by homeowners; however, Heat-Line commonly recommends that a qualified tradesperson complete the installation process

Q – What do I do if I have extra Paladin 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. Paladin 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 – If the power fails, do I have to reset the unit?
A – Heat-Line products including Paladin are designed to turn back on as soon as the power to the unit is supplied. Once re-energized the Paladin system has the ability to increase its output to immediately begin to defrost any section of the pipe that has or was close to freezing during the power outage. In many instances defrosting the pipe can take as little as an hour or less.

Q – How much power does a Paladin consume?
A – All Heat-Line brand systems including Paladin 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 Paladin heating cable systems?
A – Yes. The maximum circuit length of Paladin that is allowed on a 120V circuit is 120 ft. (37m), and or 240 ft. (73m) on a 240V circuit. For applications that require longer lengths please see EXT-R.

Q – What length of Paladin will I need?
A – The length of Paladin heating cable that will be required can change from application to application as it depends on the type and size of the pipe, the amount of insulation applied to the pipe after the Paladin is installed, and the minimum outdoor ambient temperature. In most cases, pipe diameters equal to or less than 2in. (51mm) only require a single run of Paladin for proper protection in climates as cold as -40°F (-40°C) when properly insulated. Once you have the required information collected including pipe type (metallic or non-metallic), pipe diameter, pipe length, lowest outdoor ambient temperature, number of valves or external spigots, and potential insulation thickness you employ the Paladin length selection chart or contact Heat-Line directly to speak with a product specialist.

Q – Can Paladin be cut to length if too long?
A – No. The Paladin system manufactured by Heat-Line is a pre-assembled factory terminated advanced self-regulating heating cable system that is not designed to be field terminated and or tailored to length. 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.

Q – My Paladin system is too short; can I add a small section onto the end? If not, what can be done?
A – No. The Paladin system manufactured by Heat-Line is a pre-assembled advance self-regulating heating cable system that includes a proprietary end-seal termination and elastomeric heating cable jacket engineered to be certified for direct burial and wet locations. As such the Paladin system cannot be spliced together in the field. If greater length of the Paladin is required you may purchase a single continuous product of the proper length, and or relocate a second power source and install an additional Paladin system to complete the required freeze protection.

Q – Can I install the Paladin system on a pipe that is inside a wall?
A – No. It is not recommended to install the Paladin heating cable system behind a wall as this renders the product unserviceable and means that it is not easily inspected should the product and or piping need to be examined.

Q – What type of insulation should I use with the Paladin 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 Paladin heating cables is fire resistance waterproof 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 the Paladin heating cable system?
A – The Paladin 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 800-584-4944.

Q – Will the Paladin system work with DC voltage?
A – No. The Paladin heating cable system is designed to work with AC voltage only. For 12 volt or 24 volt DC applications see Kompensator.
