Heated Sidewalks is a Smart Business Choice

Cut Snow Removal Labor Costs and Increase Pedestrian Safety with Radiant Heat

Most of us may associate a radiant snow melting system with a heated driveway. Why not apply the same smart technology that comes in a snowmelt system, to a sidewalk? Pedestrian safety is key when running a business or taking care of public buildings such as schools or libraries. Using a radiant snow melting system underneath a sidewalk would be a significant perk to any existing or new project where pedestrian traffic is being taken into account. Having walks clear of snow at all times would increase traffic and safety.

Radiant snow melting systems are relatively affordable and save you in the long run when it comes to snow removal cost and headaches. The fully automated snow melting systems are simple to maintain because they require no human intervention. They do however come with a manual override should you ever need to melt a snow drift that collected on your driveway or ice that formed in some shade.

Radiant snow melting systems utilize radiant heat beneath the concrete or asphalt to help keep walks clear of snow and ice. This makes walking much safer for pedestrians in cold climates. Each snow melting system can be customized to meet your specific project needs and they fit in uniquely shaped areas as well. Using a snow melting system anywhere there are pedestrians is a sure way to keep everyone safe and dry

The Snow. The Heated Driveway. The Melting.

Radiant Heated Driveways Make Snow Removal So Simple

Every day it snows millions of us curse its accumulation. We point our fist to the sky, shaking it with fury and scream WHY? ENOUGH ALREADY! MAKE IT STOP!!! It’s not that we don’t enjoy the beauty of snow or the extremely fun winter sports that it allows, it’s just that, well, we’re sick to death of shoveling, snow plowing, slipping, sliding, falling, and wishing it would just melt on its own. The oversimplification of snow removal is possible. First you get the snow, then the heated driveway , and then oh heavenly day, the melting. Once a radiant heated driveway is installed the hard work is over.

It does sound simple. Maybe a little too simple, but the beauty of it is that it’s real and exists. A heated driveway takes the once burdensome snow and makes it pretty again. You can sit back and watch it fall without a single curse word uttered or fist shaking. A radiant heated driveway does all the work for you.

These fully automated systems activate when temperatures reach a certain set point and precipitation is detected. There’s no labor involved. The systems also feature manual override capability in case you want to turn on the heated driveway to melt a snow drift or if some ice somehow formed in the shade. All in all, these heated driveway systems couldn’t be easier or more reliable

Heated Driveways and Snow Melting Systems (Part I)

Whether you’ve been living comfortably in your house for years or you are building a new home, installing a radiant heated driveway is a viable option for you. Certainly it is more practical to install a radiant snow melting system during the initial construction phase of a driveway, but unknown to some homeowners is that both asphalt and concrete driveways can be retrofitted with electric radiant heat systems.

Hydronic Snow Melting Systems

There are two types of driveway heating systems available today: hydronic systems and electric systems. Hydronic snow melting systems utilize a mixture of water and propylene glycol (anti-freeze) that circulates through a closed-loop network of flexible polymer (Pex) tubing that is installed in the concrete or asphalt. The liquid is heated by a water heater/boiler and then circulated through the Pex tubing by a pump to heat the driveway and melt snow. The condensing boiler (water heater) can be powered by any energy source, including natural gas, electricity, oil, wood, or even solar collectors. Because of this, hydronic snowmelt systems can offer a slightly lower operating cost than electric systems, especially for large snow melting applications.

Warmzone hydronic systems feature highly efficient condensing boilers with an Energy Star Rating as well as industry leading pumps, valves and tubing. Unfortunately, when it comes to retrofitting a driveway with hydronic radiant heat, the only way to accomplish this is to tear out the old driveway and install a new one.

Electric Heated Driveways

Electric radiant snow melting systems are easier and cheaper to install than their hydronic counterpart. Both existing concrete and asphalt driveways can be retrofitted with electric radiant heat.

Heated sidewalks being installed

Electric snow melting systems utilize specially engineered ClearZone heat cable that is available on spools or pre-spaced in mats that can be easily rolled out during installation in concrete, asphalt or under brick and stone paver driveways and sidewalks. The ClearZone cable is UL listed and consists of a twin conductor with FEP/XLPE insulation and polyolefin jacketing that provides flexibility and excellent UV protection. The heat cable is rated at 220°F and has a minimum 10-year warranty. Designed to produce 30-50 watts per square foot, ClearZone radiant heat cable has the quickest response time (time to heat the driveway upon system startup) of any snow melting system on the market. Because electric snowmelt systems do not rely on heating water heater before pumping the liquid through PEX tubing, the response time is considerably less than that of hydronic systems.

Fully Automated Snow Melting Systems

The fully automated driveway heating system features heat cable, a control unit (controller), and a high-performance snow sensor (activation device). One of two types of sensors (aerial or pavement mount) can be installed, depending on the project. Aerial mount sensors are typically used for residential heated driveways while pavement mount snow sensors are more commonly used in large commercial snow melting applications.

When the snow sensor detects precipitation and temperatures are below a designated set point (usually set at 39 F), the sensor signals the master control unit, initiating startup of the snow melting system. While the driveway snow melting system is fully automated, it can also be activated manually. The controller includes a manual override function for times when snowdrifts or ice forms because of wind or shaded areas. Another especially attractive feature of electric heated driveways is that the systems do not feature any moving parts, so they are virtually maintenance free and extremely reliable.

Continued from Part I

Installing an Electric Radiant Snow Melting System
To install a ClearZone snow melting system in concrete, the driveway is first prepared for the concrete pour, including the placement of rebar or remesh. The durable heat cable is then secured to the wire remesh or rebar with zip ties and then the concrete is poured. Concrete seats or “Mesh-Ups” are often used with wire remesh to ensure proper positioning of the cable.

In addition to the heavy stress of fresh concrete pours, ClearZone cable is also designed to withstand the extreme temperatures of hot asphalt applications. The cable is laid out and then the asphalt is applied on top and then compacted, resulting in a discreet, maintenance free asphalt heated driveway. You can lay out the mats or space the cable yourself, but it’s important that a qualified electrician connect the wiring for the snow melting system.

Retrofitting Existing Driveways with Radiant Heat
To heat an existing asphalt driveway, the process is surprisingly simple. The cable is laid on top of the old asphalt and then the new layer of asphalt is applied on top and then compacted. Retrofitting a concrete driveway with radiant heat is a more tedious affair. Grooves are cut in the existing concrete, using concrete saw-cut technology, and the heat cable is then placed in the freshly cut grooves. An epoxy topcoat is then applied over the newly embedded cable sealed to seal the heating cable. A sand broadcast can be applied to the surface before the epoxy cures for additional traction and safety. Saw cut technology can also be used for retrofitting asphalt driveways if desired.

Radiant Snow Melting System Options
There are several options when it comes to installing a radiant snow melting system. For example, you can heat the entire area of a driveway, or perhaps just an 8-foot strip in the middle or just a pair of 2-foot-wide tire tracks. Radiant heated driveways and snowmelt systems can be tailor made for virtually any of your snow and ice melting needs. The applications are limited only by your imagination, and the experts at Warmzone will work closely with you to determine the best system for your needs.

Eliminate the need for the use of harsh snow melting chemicals and prolong the life of your driveway with an environmentally friendly radiant snow melting system. Not only can installing a radiant snow melting system increase the value of your home, but it will also increase pedestrian safety. So enhance your safety and peace of mind by calling Warmzone and learning about the options of installing an automated snow melting system today.

It’s Not Too Late to Heat Your Driveway (Part II)

Read Part I

The methods outlined in Part I are the least intrusive for retrofitting your driveway with radiant heat. However, there are those particularly ambitious consumers who opt to remove portions – or even all – of their existing driveway. Obviously, the ideal situation is to install a snow melting system during the original construction, but if you have a driveway on a steep hill or have extreme snow melting needs, removing portions of existing concrete to install a radiant heat system is still a worthwhile venture.

As shown in the photos, the old concrete is removed and then new rebar is installed in anticipation of the new concrete. The ClearZone heat cable is secured to the rebar and the concrete is then poured. Much of the cable can be installed by handy “do-it-yourself” types, but all the electrical work should be completed by a qualified electrician. (An important thing to remember is that a heated driveway / radiant snow melting system is only as good as the installation. The cable must be properly spaced and wired in order to accomplish the desired results.)

The Many Benefits of an Electric Snow Melting System
Radiant heat snow melting systems eliminate the need for manual snow removal –such as plowing – that can damage the driveway. Furthermore, there is no need to use salt and other abrasive snow melting chemicals that are harmful to grass and nearby vegetation.

Make Every Dollar Count with Radiant Heated Driveways

You might be like many of us and are afraid to even say the word recession. If we say it then we’ll have to admit it’s really here and our spending choices have to be even more prudent. Economic downturns such as the one we find ourselves elbow deep in, dictate wiser, well-researched and more cost-effective purchases. The weak dollar and tighter credit allowances no longer allow the penny-pinching consumer the luxury of frivolous spending sprees. Each purchase needs to count and provide an investment for the future.

A cost-effective investment and smart way to add value to your home is by installing a heated driveway (radiant snow melting system). Once installed, an affordable radiant heated driveway provides low operation costs in the long run, helping you lower your bottom line on home expenses. A heated driveway with an area of 300 square feet operates for under 50-cents per continuous hour of operation. Snow melting generally only takes a few hours to clear your driveway when a storm hits.

Driveway heating is an investment that has demonstrated and visible results. Not only does it allow you some free time with your family – not to mention saving your back from shoveling duties – but it is a proven way to protect the life of grass and surrounding vegetation by eliminating the use of salt and harsh snow melting chemicals. It also extends the life of your driveway by defending it from chemicals and other traditional abrasive snow removal methods.

Radiant heated driveways are fully automated so you can stay inside where it’s warm and count the dollars you are saving as you watch the snow fall. An automatic snow sensor signals the snowmelt system’s controller when precipitation is detected and temperatures are below 39° Fahrenheit. The controller then sends power to the embedded heat cable, rapidly warming the driveway and keeping it clear of snow and ice. The system shuts off automatically after the storm. Electric radiant snow melting systems have an extremely fast response time, operate silently, and are maintenance free – and there are several options to choose from when considering a radiant snow melting system. There’s really no better, or easier way to keep your driveway clear of snow and ice during the winter than with a radiant heated snow melting system.

So, instead of shoveling for hours after a Nor’easter or powerful lake effect storm, you can spend time relaxing inside with your family. The peace of mind that comes with making a smart purchase is invaluable right now. We all look for ways to ride out recessions and worrisome economic climates, but you can still enjoy some of the finer things in life by making wise investments in quality products.

Installing a Heated Tile Floor (Part II)

(NOTE: This article is intended only as a general guide for installing a heated floor. For detailed installation instructions, refer to your system’s installation manual. Warmzone also offers an abundance of radiant heat documentation, illustrations, and installation guides online for your convenience.)

If you are replacing your existing floor with a new, radiant heated tile floor, then naturally, step one is to tear out the old floor surface. (In many cases, you can actually install a heated floor over an existing tile surface, but that often presents problems with door clearances and what not, so for simplicity, we’ll stick to removing the old floor.) Once your old surface is removed, make sure you have no sharp objects protruding from the subfloor and clear the surface of all dirt and dust. Next, lay out your ComfortTile heating element.

Cutting mesh backing to make turns with CT mats

The ComfortTile heating mats feature heat cable that is pre-spaced and attached to an adhesive-backed fiberglass mesh that can be easily rolled out during installation. To make turns when laying out the floor heating mats, simply cut the mesh backing and turn the mat accordingly, (see photo). Never cut or damage the heat cable.

When installing the heat cable off the spool, the cable is secured to the floor using thin metal strips (cable straps) that are nailed or screwed to the floor. These straps have small tabs in them where the heat cable is placed. Simply bend the tab over the cable to secure it.

Thinset can be applied directly over heat cable

To install the floor sensor, cut a channel approximately 10 mm (¼-½-inch) deep and about an inch wide in the wall and about 3½ feet out into the subfloor. (This groove runs from the wall-mounted thermostat down to the heat cable in the floor.) Glue the flex pipe for the sensor into this channel and seal the end of the pipe with a piece of tape. Run the wire from the floor sensor up to the thermostat. (It is recommended to have a qualified electrician complete the floor heating system’s wiring.)

Once the cable and sensor are secured, you can install the tile. Using a large notched trowel, apply thinset directly over the heat cable. Another method is to pour a layer of self-leveling lightweight concrete over the heating mats. After that sets, simply apply the tile on the surface. This method is usually preferred among tile setters as it offers more protection for the heating cables when you are installing the tile.

We live in an age of available information for do it yourself people. Imagine the difference you can make in transforming that cold floor into one of extreme comfort. A small radiant heated floor project could be done in a day or two, but the comfort will last a lifetime.

ComfortTile floor heating systems from Warmzone are among the best in the industry and will provide you with reliable, energy-efficient, maintenance-free operation. You’ll not only increase your comfort, but the value of your home as well.

What are the Best Options for Keeping Your Driveway Clear of Snow and Ice?

Every year it comes, and every year we fight it. I’m talking about snow . . . lots and lots of snow. Sure, it’s pretty and helps to put us in a festive, holiday mood, but the truth is that snow can drain our wallets, sap our strength and even impose on our sleep or leisure time.

Most folks who live in cold climates have become somewhat accustomed to getting up a little earlier or staying up a little later in order to shovel snow from their driveways or clear their roofs and gutters. Usually the shoveling of snow is followed by the disbursement of salt or other snow melting chemicals. Some homeowners – and businesses especially – opt to pay someone else to manually remove the snow. But is manual snow removal really the best way to rid our sidewalks and driveways of snow and ice? There is, in fact, another option – radiant heat.

Radiant heat snow melting systems are fully automated, so once they are installed, there’s no need to worry about snow removal ever again. Electric snow melting systems consist of three components: The heat cable, a snow sensor (activation device), and controller. (Hydronic systems also include a boiler and pump.)

Heated driveway in concrete

The heat cable features a thick wire that is surrounded by layers of insulation, copper grounding braid and a protective outer layer of PVC or polyolefin to form a flexible cable about ⅛ to ¼ inch in diameter. Cable is available on spools as well as in mats. These mats have the heat cable that is pre-spaced and attached to a mesh backing, and can be customized (cut) to suit virtually any type of layout, including driveways, ramps, common walkways and sidewalks, etc.

The activation device for the snow melting system activation device can be either an aerial-mounted or pavement-mounted snow sensor. These sensors activate the system when there is moisture present and the temperature is below approximately 38 degrees. Most systems also include a manual timer to preheat an area before a large storm to curb snow and ice accumulation or to eliminate snow drifts.

When the snow sensor detects the right conditions, it signals the control unit which then sends power through the heat cable. The system warms the surface quickly so that the first snowflakes melt immediately as they land on your heated driveway.

Electric and Hydronic Radiant Snow Melting Systems

What are the Pros and Cons of each Method of Radiant Heating?

First of all, it is important to clarify that one method of radiant heat cannot claim universal superiority over the other. Both types of radiant heat are popular. That being said, each system does possess distinct attributes and advantages.

Electric Radiant Snow Melting Systems

Electric snowmelt systems utilize rugged heat cable that distributes heat evenly across the surface of the driveway or sidewalk. The heating cable is durable enough that it can be installed in new concrete pours, under pavers and even in harsh, high-temperature new asphalt construction projects. It is secured to the remesh and generally spaced at 6 inches while being embedded within about 2 inches of the surface.

The Top Advantages of Electric Radiant Snow Melting Systems

Ease of Installation – Electric radiant heat systems are fairly easy to install. (Handy do-it-yourselfers can do most of the installation. It is important, however, for a qualified electrician to install the wiring.)

Energy Efficient – Electric radiant systems boast a rapid response time, heating the area quickly and efficiently (99% of all energy goes to snow melting, so there is virtually no wasted energy).

Lower Installation Costs – Because electric systems can be installed quickly and easily, the installation costs are minimal.

Maintenance Free – Electric radiant heat systems do not use any moving mechanical parts, so the system is virtually maintenance free.

No Mechanical Room is Required – Electric systems consist of three main components: the heat cable, a snow sensor (activation device), and the controller. So, unlike hydronic systems that utilize a boiler and pump, there is no need for a mechanical room.

SUMMARY: For small to medium sized snow melting applications, electric radiant heat is generally the best choice.

Hydronic Radiant Heat

Continued from Part I

Hydronic heating was the first form of radiant heat, used by ancient Chinese civilizations and further developed by the Romans. Today’s hydronic floor heating systems feature PEX radiant tubing that is usually installed in concrete. For interior applications, the tubing is sometimes installed in a concrete mass called Gypsum Concrete or “Gypcrete,” or, more commonly in the grooves of the advanced aluminum panel system. The pre-cut panel method is known as a low-mass or modular board underlayment system, and is ideal for remodeling as well as most new construction projects.

The heating element for a hydronic system involves flexible tubing and specially treated water. Hydronic heated driveways use a closed-loop tubing system to heat the surface of the driveway. The tubing is generally made of a durable polymer (PEX tubing) or synthetic rubber to circulate a mixture of hot water and propylene glycol (antifreeze). The fluid is warmed to temperatures between 140 to 180 degrees F to deliver enough heat throughout the snow melting system.

The PEX tubing can be installed under a variety of mediums, including concrete, asphalt, stone pavers, etc. Successful operation of a hydronic heating system depends on proper tubing spacing and layout. Tubes are usually laid out in a spiral or serpentine pattern for even heat distribution, making initial installation a bit more challenging than that of electric radiant heating systems.

A water heater (boiler) is the heat source for a hydronic heated system, which can be powered by any energy source that satisfies the btu requirements, including natural gas, electricity, oil, wood, or even solar collectors. A circulating pump and supply and return manifolds, installed in an easily accessible location, transfer the liquid between the heat source and tubing.

Flexible Power Source Options (Low Operating Costs) – Because the boiler of a hydronic radiant heat snow melting system can utilize natural gas, oil, wood, or other cheap fuel, the operating cost for large hydronic systems can be lower than that of an equally sized electric radiant heat snow melting system.

Snow melting mats laid out to heat asphalt driveway

Electric heated driveway systems are generally more efficient than hydronic systems. Electric cables heat up instantaneously, whereas the liquid within hydronic tubing takes a while longer to be heated up before the snow begins to melt. Installation of electric systems is fairly simple for the “do-it-yourselfer”, and heat cable is also available in mats that can be rolled out for simple installation. The mats feature cable that is pre-spaced, attached to a durable fiberglass mesh backing. They can be easily rolled out to heat tire tracks or an entire driveway. This flexibility is invaluable in retrofit applications, where hydronic system installation is more evasive, and costly.

With both radiant snow melting systems, you have great flexibility in terms of the installation configuration (even more so with electric systems). Instead of heating an entire driveway, you may want to install heat cables to only melt snow in the tire tracks of the driveway. The heat cable for radiant snowmelt systems can be customized to heat just about any type of odd shaped area, large or small.

Radiant Heat Offers Flexibility in Terms of Options

If you are considering installing a heated driveway, there are three general driveway heating solutions that are typically recommended:

  1. Install radiant heating cable under the entire driveway pavement.
  2. Install only an 8-10 foot wide strip of heating cable up the middle of your driveway or main traffic area.
  3. Install two 24-inch wide tracks of radiant heat cable up the middle of your driveway.

Electric radiant heat systems usually cost less to install, and are much easier to install in small spaces. The installation of a hydronic system is much more labor intensive and costs more for materials. However, for larger systems, you will probably save more money on the heating bill compared to electric warm flooring.

Make sure you work with experienced professionals who also provide system engineering and design services, included detailed CAD drawings. Warmzone is one of the best radiant heat providers that you could hope to find. They will work closely with you to ensure that the radiant snow melting system you install is the absolute best system for your specific needs.
