Product Details

Dual Heat Tape Controller with Sensor (DS9-C)

The DS9 unit operates by detecting environmental conditions through a base mounted temperature sensor and a remote heated precipitation sensor. When rain or snow land on the precipitation sensor, your cable system will turn on. The small heater in the sensor then rapidly evaporates the moisture, clearing the sensor in preparation for the next cycle. Smart stuff. The precipitation sensor is connected to a 10 foot cable and is intended for remote mounting near the roof deicing system. Use an EX-50 extension kit (with coupler) to put the precipitation sensor up to 60 feet away from the DS9 unit. 

Signals from the sensor are supplied to the microcontroller which determines the appropriate action based on the system settings.  

The difference between “sensor” and “controller” modes is the “Delay Off” drying cycle provided by each configuration. “Delay Off” time is the amount of time the sensor/controller will hold the load control relay(s) closed after the last detection of rain or snow. Proper setting of “Delay Off” assures that heat cables have created a sufficient melted pathway through the snow/ice on the roof. 

The DS9 heat cable controller detects snow and rain in addition to directly controlling the cables themselves by pushing power into the cable only when called for. The DS9 is constructed of a durable NEMA 3R enclosure, rated for outdoor use and has a 3/4 Inch conduit hub and operates from -40F to +185F. The power pigtails are #14 Blue/Brown/Green and the load pigtails are #10 AWG Yellow.

Frequently Asked Questions

Yes We Do. However, it is fairly costly.

We have a calculated rate based on the product in your cart if you choose to ship to Canada or Alaska.

The type of clip you need for your heat tap installation is based on what kind of roof you have.

We are building a hand guide to identify what kind of roof you have and find the clips that can/should be used with that roof-type.

View the Guide Explaining What Clips You Need Here

To know how many clips you need to buy, there are two things you need:

  1. Some Basic measurements regarding your installation area & some considerations to note
  2. Our handy Heat Tape Calculator to punch in your measurements & notes

We have a guide on How to Measure for Purchasing Heat Tape that will help you. Once you have your measurements, you can find our Heat Tape Calculator here.

No plug-in ready Heat Tape should be cut, modified or altered.

Heat Tape Pro and Pipe Freeze Pro are offered in many lengths from 6-foot up to 150-foot. These products are not designed to be modified, so you should pick the length you need and work with that length. These cables should not be altered and doing so would void any warranty on the product.

Radiant Solutions DOES offer heat tape on spools that can be cut to any length by you.

We offer heat tape on spools from 250-foot to 1000-foot. These spools are designed to be cut to length, made into multiple cables, etc. Heat Tape on spools needs to be hard-wired into a junction box, or have a power connection plug-in manually added to it for use. It also requires ends to be properly sealed and terminated. When working with Heat Tape on spools, a Licensed Electrician should be utilized to assure proper wiring per regional codes and standards.

And if you are using Heat Tape Pro on your roof / eave to resolve an ice dam issue, you should use heat tape to make sure there’s a clear path through your gutters for water to escape your roof. If you don’t do that, the water could just refreeze in your gutters. You also want to get the downspouts too.

Be careful if you plan on using heat tape Only in your gutters.

There is a common misconception that gutters are a root cause of ice dams. This misconception can lead people astray when creating their strategy for ice dam deterrence. If you have an overhang on your roof (an eave), the chances are very good that you problem exists on your roof before the gutter.

Yes. Radiant Solutions Company is based in Hopkins, Minnesota.

We are a family-owned business with less than 10 employees that has been in business since 2016. Our experience with ice dams goes far beyond that: our founder Steve started a business diagnosing and solving Ice Dam problems on customer houses for almost 35 years.

Here’s a handy guide that explains the steps of measuring so you know which length of heat tape to get.

Measuring the area of your roof that is affected by ice dams so you know how much heat tape to get is not overly complex, but it does have a few variables. Use our Heat Tape Measuring Guide to understand the process and print a worksheet that you can use to make sure you have all the right numbers.

Once you have all the measurements and considerations you need, use our Heat Tape Calculator to calculate the size of heat tape you should get.

Installing our heat tape on your standing seam roof can be very effective in combating ice dam formation. There’s two main products used to install heat tape on your standing seam metal roof: The S-5 SR Heat Tape Clip, and the standard ice dam heat tape clip.

S-5 SR Clip for Heat Tape & Standing Seam Roofs

Installing Heat Tape on a Standing Seam Roof with the S-5 SR Heat Tape Clip
The S-5 Heat Tape Roof Clip is a new, patented roof clip design specifically for standing seam applications with a focus on ease of install and effectiveness. It is used in conjunction with the S-5 Base, which needs to be purchased separately. The S-5 base is designed to clamp onto the seam of a metal roof as the S-5 Clip holds your ice dam heat tape into position. Can be set up in a single or dual-clip configuration. (See product page for more info)


Installing Heat Tape on a Standing Seam Roof with Standard Roof Clips

There are specific ways/configurations used when installing heat tape on a standing seam / metal roof using standard heat tape clips. The following (2.6 – figure 16.0 & 17.0) shows a snippet of the HeatTape Pro installation manual showing two different clip configurations, more info can be found in the manual itself: Heat Tape Pro installation Manual

There is no difference.

The terms heat cable, heat tape and heat trace are all used interchangeably to described heated cables used to protect pipes from freezing, preventing roof and gutter ice dams from forming and for safeguarding temperature sensitive components.

Other terms we’ve seen used regarding Heat Tape are:

  • Heat Coils & Heating Coils – Heat Tape has been called this because of the way the zig-zag pattern looks like a heating coil-element (like inside of a toaster)
  • Gutter Trace – Heat Tape get’s called this because of the usage in and around gutters
