Affordable-Snow-Ice-Melting-Solutions

Affordable SnowMelt Solutions

By Ann Robinson and Annie Schwemmer

December 21, 2007

Snowmelt systems are designed to take the sting out of Utah winters.

Last week we discussed a permanent system to keep snow and ice off your driveway. The system, which can be expensive, features electric cables or hot water pipes running under your driveway.
Today we’ll discuss some other options that may add convenience to your winters without sending you to the poor house.

The first option is to use an electric cable system, but to install it judiciously, heating only critical areas. For instance, instead of heating an entire driveway, you could heat only narrow strips corresponding to the wheel base of an automobile.

This would allow vehicular access in and out of a garage without having to shovel the entire area until a more convenient time.

Portable heated walkway mats are one of the less-expensive options for melting snow and ice.

Perhaps you are concerned about the safety to the walkways around your home. Portable snow melting mats are one solution. The mats are designed to lie on top of existing surfaces as opposed to being imbedded in the walkway. The electric units can be placed in any area where snow and ice accumulate and work on the same principle as other snowmelt systems, continuously melting snow as it comes in contact with the warm surface.

The mats are manufactured with an electrically operated heating element sandwiched between two protective surfaces of nonslip rubber. They are durable and provide a much more secure footing for pedestrians. They are not appropriate for use in driveways.

Portable snowmelt mats operate by plugging them into any outlet. They come in either 110 or 240 volt options and in sizes ranging from 2 feet by 3 feet up to 3 feet by 25 feet. Several mats can be hooked together to achieve a configuration to suit your situation.

The cost of a 2-foot-by-3-foot mat is less than $200, while the 3-foot-by-25-foot version is more than $2,000.

Snowmelt mats come only in black, but there is another option if you already have a mat or outside rug. You can purchase an underlay mat that functions the same way as a snowmelt mat, but it only features a heating element without the rubber surface.

Stairs pose another concern. Electric rubber treads have the same slip-resistant surface as the mats but are sized to fit one to a stair tread. Sizes range from 9 inches by 2 feet ($125 each) up to 11 inches by 5 feet ($205 each). The treads are wired together and operate from a single plug.

There is also a more permanent (though pricey) solution to icy stairs. Heated aluminum stair treads can replace the steps of an existing stairway or be used in constructing a new exterior staircase. These range in cost per tread from $255 for a 9-inch—by-2-foot tread up to $510 for an 11-inch—by-5-foot tread. While the aluminum option is permanent, the mats and rubber stair treads are seasonal — just roll them up and put them away in the spring.

Portable snow mats and stair treads come with the option of automatic moisture and temperature sensors so they can respond automatically to the climate if you are not home to plug them in. They offer the same convenience and safety as a full-blown snowmelt system without melting away all your funds.

Toasty Toes Floor Warming

Toasty toes: Radiant Floor Heating Warms Tiles from Below

Northern Virginia Daily

28 September, 2007

There’s nothing like a hot bubble bath on a frigid winter’s night. And, nothing snaps you back to reality faster than stepping out of the tub and onto a cold tile floor. These days, fewer people are experiencing the discomfort of cold feet. That’s thanks to floors being warmed with radiant heat.

A room at the Old Waterstreet Inn, at 217 W. Boscawen St. in Winchester, with heated tile floors in the bathroom, is especially popular in winter, innkeeper Jeannie Faith said.

“They love it,” she said. “It’s very nice when you step in in the morning or the evening, and it’s warm under your feet. It’s very efficient. It actually helps with the heating bills to have it. We’re actually considering building a house in the next five years, and we will definitely put the radiant heat in when we build. “It gives a whole coziness to the room that you don’t have otherwise.” Faith and her Norwegian husband have a cabin in Norway with radiant heat in the bathroom and kitchen.

“In Norway, they would never put a tile floor down without radiant heat,” she said.
WarmQuest, based in Salt Lake City, sells two types of radiant heating systems, Tuff Cable and ZMesh, said Ryan Bench, the company’s Web master. ZMesh is a 12-inch-wide bronze screen heating element that is no thicker than screen-door material, he said. It can go underneath carpet, hardwood floors and tile. The Tuff Cable is for tile and cemented floor coverings and causes a little floor buildup, Bench said. According to heatizon.com, Tuff Cable uses a 10-gauge coated copper cable. Heatizon manufactures Tuff Cable and ZMesh.

With the ZMesh there’s virtually no buildup, he said, and it’s nailed or stapled in place, so long as there’s no conductive material where the nailing or stapling would go. “[Radiant heat] heats up the floor, and then it starts heating up the objects that are on the floor,” Bench said. “So, it’s not heating up the air. It’s heating up the objects instead. Also, objects radiate out the heat.

“All the power that goes in, goes back to the transformer and makes it pretty much a loop.”
Both of WarmQuests’ systems are low-voltage, he said. “It has a step-down transformer with a control box that converts high-voltage to low-voltage,” Bench said.

About 12 to 15 volts are put out per square foot. Putting in radiant heat is popular in remodeling jobs, Bench said. The company also uses it for de-icing and snow melting in roofs and driveways. The Tuff Cable goes in driveways and ZMesh under asphalt roof shingles.

The spaces they are used for vary. “We have systems for small bathrooms 110 square feet and less,” Bench said. “We also have systems for as big as you want to go. Some people put it in their entire house for their primary heat source. Some people supplement their heat source with it. A lot of it’s new construction as well. It’s starting to get really popular.“It’s economical to run, depending on what your kilowatt hour rate is. [It] usually cuts down on utilities, especially if it’s supplementing the heat source.”The larger the area of the house being heated with radiant heat, the cheaper the square-foot price, he said. For instance, a 110 square-foot bathroom might cost $10 to $12 per square-foot, compared to $8 per square-foot for larger areas.A different style of radiant floor heat, hydronic radiant heat, is used by Whittington Construction Co. in Front Royal. Water is used either from the home’s hot water heater or a separate boiler system, Steve Whittington said. It runs through tubing in the flooring.

He said this system has been installed in two or three of the custom homes the company has built. “It’s just coming to this area,” Whittington said. “It’s been slow-moving up here because the cost is quite a bit more. It’s the initial installation cost.”

He said the system was installed throughout an entire house that had concrete floors, while another house just had it on the first floor, in the great room, kitchen and bathrooms.

“The one that I’m working on now is going to be in the bathroom, kitchen and eating area,” Whittington said. This latest home has piping that’s already integrated into the subfloor when the panels are bought. It is known as warmboard, Whittington said. There are several benefits to radiant floor heat, he said. “When you get up in the morning, if you have hardwood floors, or if they’re [a] non-carpet surface, these are really more comfortable, and really, it’s more even heat,” Whittington said. “Radiant heat heats up the whole mass, and it radiates from that point to heat the entire mass up. With forced-air heating, you have hot spots and cold spots.”

WHY ETL & CSA? UL vs. ETL

OSHA the Occupational Safety and Health Administration, the US government’s enforcement arm for safety and health issues has been tasked with overseeing professional independent testing laboratories. The best known of all independent testing laboratories is Underwriters Laboratories, UL.

UL was established by insurance underwriters to find ways to reduce unsafe hazards in the marketplace, thereby reducing dramatic insurance claims. Since its inception, UL has, been involved with writing standards of safety acceptability in the United States. They have been one of the premier developers of safety standards but they have not been the only group to write standards. Groups like NEMA, IEEE, and ANSI have also contributed to the development of standards. Similarly UL is not the only independent testing laboratory.

OSHA has become the certification agency for independent testing laboratories in the United States. A group of engineers who decide to do testing as a business must qualify through OSHA to function as an independent test facility. Further-more, they must show competence in specific areas, fire testing, for instance. Once they have demonstrated competence in the area of fire testing and have shown that they possess the facilities and equipment to do fire testing, OSHA will certify them as a Nationally Recognized Testing Laboratory (NRTL) to do fire testing. Factory Mutual, FM, is one such NRTL for fire testing, Southwest Laboratories is another.

Many independent testing laboratories have NRTL status. Most are relatively specialized and limited in their scope. The three major testing laboratories that operate in the United
states that have a wide scope of testing qualification are, UL, CSA, and ETL. They are certified by OSHA as NRTLs.

NRTL status tells all customers that the services performed by these companies, to list or to label products, is reliable and legally binding throughout the United States. ETL, originally known as Edison Testing Laboratories, is an old, respected, nationwide testing group with credibility equal to UL or CSA. Therefore an ETL listing label is legally binding nationwide and should instill equal consumer confidence in the manufacturer that they have cared enough to submit their products to the rigorous safety compliance process and achieved the right to apply a Nationally Recognized Testing Laboratory label that certifies compliance assurance.

Radiant Roof Snow Melt and Deicing

Damage caused to buildings, people and property by snow and ice build-up and removal, ice dams, and icicles amounts to millions of dollars each year. The effectiveness of the methods historically used to manage snow and ice related problems has been spotty at best. The traditional methods used to prevent these large dollar problems fall into three categories: “Icicle Management”, “Water Channeling”, and “Elimination”. Each of these three categories traditionally includes one or more of the following approaches:

Icicle Management – This category encompasses those efforts designed to eliminate or otherwise manage the icicles along the eave line and do not attempt to address the causes nor problems resulting from ice dams. Traditional methods used to manage icicles along the drip-edge of the eave include: nothing or the “ignore them and they will eventually go away, hopefully before something or someone is damaged”, approach, labor intensive and dangerous manual removal, and expensive and often times cosmetically unattractive high voltage cables or hot liquid tubing sandwiched between two layers of metal.

Water Channeling – Included in channeling are high voltage cables that are attached to the top of the roof covering material. Installed in a fashion that looks like the letters “W” or “V” high voltage cables are attached to the shingles or other roof covering material with a variety of proprietary clips. Once attached to the shingles and energized these high voltage products are designed to provide a channel for water, created by melting snow and ice, to travel off of the roof.

Elimination – This approach is designed to eliminate snow and ice from both the roof in a manner that reduces or entirely eliminates icicles from the eave edge and eliminates the potential damage caused by ice dams. Historical experiments designed to eliminate snow and ice from the roof included partially effective and prohibitively expensive experiments such as heating the attic space and attaching hot liquid filled tubing to the underside of the sub-roof. Unfortunately these experiments most often result in exorbitant energy costs and many times contributed to and/or intensified the problem originally targeted for solution.

Heatizon Systems’ patent pending radiant roof snow melt and deicing products are the only products available today that are installed on top of the sub-roof and below the roof covering material and designed to eliminate snow and ice from the roof and manage the icicles along the eave edge. Period!

In addition Heatizon Systems radiant roof snow melt and de-icing products are:

Listed to UL Standards by Intertek, a nationally recognized testing laboratory approved by the Environmental Protection Agency, and have earned the right to carry the ETL mark.
Backed by an industry leading 25 year warranty on both ZMesh and Tuff Cable heating elements.
100% efficient.
Proudly made in the United States of America.

Benefits of Radiant Heating

The Benefits of Radiant Heating:

How Do They Compare With Other Heating Applications

Some of the benefits of radiant heat:

Comfort: Let your bare feet soak up the warmth of soothing heat without the dust and noise associated with other heating sources. Enjoy evenly distributed heat throughout your home kitchen, bedroom, bathroom and basement.

Custom Designed: Whether for supplemental floor warming, or total space heating, every system is custom designed to fit all rooms independent of their shape or size. These systems will heat under any surface including marble, slate, carpet, hardwood and tile. The compact Control Box will hang on the wall of your garage or in a utility room. No heating vents or ducts will be seen, and no furnace or boiler is required.

Perfect for Remodeling and Additions: The simplicity of the low voltage heating element makes this system incredibly easy to install in your remodeling or room addition application. No floor buildup is necessary and no additional construction costs are incurred. The unique heating element can also be installed in between floor joists to heat an existing floor or room.

Safe: So safe, in fact that nails, water, and even touching the heating element during operation will have no harmful effect! You will have peace of mind while loved ones play as the systems are tested to UL standards and run on worry-free, low-voltage energy (8 to 32 V.).

Reliable: The solid-state heating systems are virtually maintenance free and the heating element is backed with a 25 year industry-leading warranty. With no moving parts and advanced self-diagnosing technology, there is no need for yearly maintenance or service checks.
Efficient: Radiant heat is the most efficient form of heat available. Significantly less operating time is required to maintain the desired warmth compared to furnaces and other radiant heat systems, keeping operational costs to a minimal. Low-voltage radiant heating systems run 98% to 100 % efficiency at any elevation as they evenly heat every area of the room.

Convenient: Our accurate thermostats allow you to easily adjust the floor or air temperature of your space heating or floor warming system. You also have the option of programming the exact time of day you want your system to operate. Simply relax, enjoy the comfort, and know that your system will work for decades to come.

So lets compare to other heating applications. Radiant Heat versus other applications:

Radiant Heat vs. Hydronics at a Glance

Both electric and hydronic radiant heat systems have certain advantages for specific applications. The following highlights the advantages low voltage radiant heat systems have:

A Boiler Room is required to run a hydronic radiant heat system. A 17″x12″x7″ Control Unit is required to run low voltage radiant heat system.

Gypsum or concrete slab is required for installing a hydronic system. It is estimated that it costs approx. $4.00 or more per square foot to install a hydronic in-floor heating system than it does to install a in-floor heating system.

The ZMesh heating element is installed directly under the floor surface without any floor buildup. The 12″ wide ZMesh is rolled out over the area to be heated then nailed and/or stapled to the wood subfloor.
Electric radiant heat warms your floors evenly because it uses 100% of the system’s energy. A hydronic system, however, heats the floor less the further away the hot water gets from the boiler (see illustration below). Hydronic systems use only 65-85% of the system’s energy. At higher elevations, electric radiant heat still is 100% efficient, where as hydronic systems are even less effective than at sea level.

Radiant Heat vs. Forced Air at a Glance

A room with floor Radiant In-Floor space heat will have a very uniform temperature from the ceiling to the floor. Heating a basement floor is the ideal application for our radiant heat systems. If you’ve lived in a house with forced air, you can crank the heat up, but the basement floor is still chilled. Installing a floor warming system will add comfort and warmth to your lifestyle.

A room heated with a forced air furnace will have cold floors and the warmest air at the ceiling. Although the air may be heated, the floors will be chilled and uncomfortable, especially for children playing on the floor.

ZMesh Radiant Heat Versitility

ZMesh Radiant Heat

Heatizon Systems

When people associated with the radiant heating and radiant snow melting industry use the words “ZMesh”, “Golden Mesh”, “Z Mesh”, or just plain “Mesh” usually they are referring to a durable line of low voltage electric products made by Heatizon Systems and used for Radiant Roof Snow Melt and De-icing, Radiant Floor Warming and Radiant Heating.

Designed to be installed on and under sub-floors and on sub-roofs, ZMesh provides a nice uniform heat and it is plenty robust to satisfy the demands of discriminating radiant heat, radiant roof snow melting and de-icing, and radiant floor warming customers. In addition, gold colored, ZMesh delivers unparallel performance and is backed by an industry leading twenty-five (25) year warranty.

What about the nails, screws, and/or staples used to attach certain flooring and roofing materials? No need to worry about nailing, screwing or stapling through ZMesh as long as the nail, screw, or staple does not come into contact with anything else electronically conductive. In other words, ZMesh should never be installed over or under metal roof decking, valley metal, metal flashing, etc. or metal roofing materials such as steel or copper but its durable sister Tuff Cable may be installed over and under such products. ZMesh can be installed, however, under all non-conductive roof shingles and nearly all floor coverings.

Unlike its line voltage and hydronic radiant heating, radiant in-floor and under floor warming and radiant roof snow melt and de-icing competitors, ZMesh is very simple and easy to repair in the event it gets cut or damaged. Repairing ZMesh requires a customized copper splice plate and a bit of solider. No one else in the radiant heating, radiant floor warming and radiant roof snow melt and de-icing business can honestly make that claim.

How much floor build-up does ZMesh require? Since ZMesh is only 1/16th of an inch thick and does not require a bed of light weight concrete or other cementous material to draw the heat away from it the answer to this question is “very little”! As a result using ZMesh avoids the expense of a cementious mud bed, the cost of the extra structural integrity necessary to support the weight of the concrete and the challenges created by the need for the additional framing required by radiant high or line voltage and radiant hydronic or hot water alternatives. Once again, ZMesh requires little or no floor build-up.

For radiant in-floor and under floor warming and radiant heating applications ZMesh may be installed in the floor (on top of the sub-floor and below the floor covering) or under the floor between the joist space. As a matter of fact, Heatizon Systems was one of the pioneers of retrofitting its products into the joist space of existing structures.

ZMesh is a cut to length in the field product rather than a fixed length product like most all of its UL listed radiant line or high voltage competitors. The ability to vary the length of the ZMesh enables the installer to adjust the radiant in-floor heating, radiant roof snow melt and de-icing or radiant floor warming system to fit the area rather than requiring that the area to adjust to the radiant in-floor heating, radiant roof snow melting and de-icing or floor warming system.

Available in lengths that extend from 50 feet to 400 feet and widths of 9 and 12 inches, ZMesh is plenty versatile to satisfy the needs of most projects. In addition ZMesh has the ability to deliver up to 11.5 watts or over 39 Btu’s per linear foot so it is plenty robust to heat entire spaces, warm spacious floors, and manage the risks of ice dam related roof damage.

Heatizon Systems cares about its customers and their property as a result all of its products have been tested to UL Standards and has earned the privledge of being listed by ETL, an internationally recognized testing laboratory approved by the United States Environmental Protection Agency.

Heatizon Systems products are proudly manufactured in the United States of America and may be purchased by fine distributors located across North America.

Launstein Hardwood Floors

Launstein Has Wood Floor Answers

by Dan Perfitt

– June 2006-

Launstein Hardwood Floors

The Phones usually start ringing about 6 am every morning here at Launstien Hardwood Flooring Company. The answering machine will pick them up until 8 am when the sales staff and radiant test guys come marching through the door with coffee and doughnuts; ready for another long day of fielding questions, offering advise, and sometimes solving problems that occur with wood floor over radiant heat. The calls come from all over the country, even a few from Europe and Canada. From contractors, manufacturers, distributors, and homeowners all with different questions and situations.

One of the more popular questions is, “what’s the best radiant system to use in our house?” Warmboard, Watts, or Wirsbo? Or should be go with electric or hot water? Sorry folks – we do not test the efficiency or quality of the systems – that has already been done. Nor do we promote one system over the other. We only test how wood floors can react to the heat they put out. You can get your questions about efficiency and quality answered from the manufacturer’s page and the radiant partners pages of our website.

We welcome all of these questions, even if they do not use our wood floors, because we feel it is our job to educate and offer guidlines to folks who want radiant heat and wood floors in their homes. There has been much written about wood floors over radiant heat, most of it is good information, but on the other hand, some of it is vague and often confuses people to the point of frustration. Realistically, there is a right way and a wrong way to complete the job.

Just returning from the RadFest West in Tacoma, WA and talking with many contractors and distributors, reaffirms our thoughts that the radiant industry is growing by leaps and bounds. An indication of this is attending any home show and seeing a radiant company there. Two or three years ago this wasn’t happening. With the increasing demand for radiant heat, there is an increasing demand for wood flooring over radiant heat. We are here to help meet that demand and answer andy questions that we have learned the answers to with testing in out radiant lab.

With the continued support of the RPA and it;s board of directors, along with the radiant companies and businesses (RPA members) that have teamed up with the RPA, we feel that the technical knowledge gathered by support companies can only further the advancement of the industry.

Membrane Roof Deicing

Roof Deicing Under Membrane Roof Covering Materials

By Steven D. Bench

Managing Member, Heatizon Systems

Heatizon Systems makes roof snow melt and deicing products that utilize one of two different heating elements, Tuff Cable or ZMesh. Tuff Cable, a copper cable surrounded by an insulator which is surrounded by a jacket, is designed to be utilized in a Heatizon Heatsink Kit under medal and other electronically conductive roof covering materials. ZMesh, a bronze product that is approximately 1/16th of an inch thick, is designed to be installed under non-conductive roof covering materials such as composite, shake, asphalt, and fiberglass shingles as well as membrane roof covering materials.

In the testing performed by Intertek Testing Services N A Inc., immediately prior to ZMesh receiving its listing to UL Standards and CSA regulations, it was noted that ZMesh, when surrounded by insulation on all six (6) sides, reaches a temperature of approximately 125 degrees F at normal operating conditions. Of course when melting snow and ice off of roofs ZMesh is not surrounded by insulation and the roof temperature at the time the ZMesh is energized is typically be between 30 and 38 degrees F resulting in an expected operating temperature substantially below 125 degrees F. In the event the roof covering manufacturer establishes a particular maximum exposure temperature for his product that is below 125 degrees F it is very easy to control the maximum temperature achieved by the ZMesh using a temperature probe that shuts the system off in the event ZMesh exceeds the maximum set point.

When selecting which roof covering materials may be put over ZMesh it is important to obtain answers the following questions:

Will the roof covering material, and any adhesive material or technique required to attach it, be adversely affected by the alloy bronze?
Will the roof covering material and any adhesive material or technique required to attach it, have an adverse affect on ZMesh?
Can the roof covering material withstand a temperature below it equal to 125 degrees F? If the answer is no then a temperature sensing device must be utilized to establish an upper temperature shut off.
What is the R-Value of the material under the ZMesh?
Is the R-Value of the material under the ZMesh greater than the R-Value of the roof covering material?

Over the past eleven years, ZMesh has been successfully installed and operated under many projects that have also utilized membrane roof materials. These projects include the Ramirez Home is Salt Lake City, UT, the Post Office in Ketchum, ID, and Sarnafil’s membrane roof covering manufacturing facility in Canton, MA.

Electric Radiant Product Myths

The Real Myths When Comparing Low Voltage & Line Voltage Radiant Heat Products

by Steven D. Bench – Managing Member of Heatizon Systems

A couple of years ago Warmzone Management LLC (“Warmzone”), an internet marketer of some Radiant Heating and Snow Melting Products and former distributor of Heatizon Systems ZMesh Roof Snow and Ice Melting Products, discovered that competing against Heatizon Systems award winning Radiant Heating products was difficult. Unfortunately, rather than accepting the challenges inherent in a competitive marketplace, Warmzone decided to attempt to fool its potential customers with an article titled the “Myths of Low Voltage Verses Line Voltage Radiant Systems” November 6, 2008, By Warmzone.

Normally, Heatizon Systems does not respond to negative advertising and marketing campaigns and, as a result, we have not responded to Warmzone’s article until now. Heatizon Systems decided to make an exception in this case because of the amount of misinformation contained in Warmzone’s article and we chose to do it now because, as one of our customers recently pointed out, it is irresponsible for Heatizon Systems to allow our past and prospective customers to be exposed and possibly influenced or confused by the non-factual misinformation contained therein.

Warmzone’s “Myth 1: Low voltage radiant systems are safer than line voltage.”

Fact 1:

Safe products are easy to identify by simply making certain that they are Listed to UL Standards or Certified to CSA Standards by a Nationally Recognized Testing Laboratory like Intertek/ETL, UL, CSA, and others. Both low voltage and high voltage systems can be safe. Low voltage products, like Heatizon Systems’ ZMesh, Tuff Cable, and Floorizwarm, incorporate computer technology designed to constantly monitor and shut the systems down in the event the current changes. On the other hand, high or line voltage products, like Heatizon Systems’ Heatwave, GutterMelt, Hott-Wire, Radiant Trak and Cozy Heat use circuit breaker safeties that shut the systems down in the event the insulation between the current carrying conductors and the grounding shield becomes compromised.

Warmzone states: “The real question we should be asking is how durable is the cable against damage and how well is the cable insulated.” Of course we cannot speak for other manufacturer’s products, but Heatizon Systems’ Cozy Heat, Floorizwarm, Hott-Wire, and Tuff Cable products are all tested and Listed by a Nationally Recognized Testing Laboratory, have been successfully installed in/under asphalt and concrete, under pavers and into thin-set in thousands of projects and have been serving customers heating and snow melting needs since 1979.

Warmzone states: “Some low voltage heating wires are NOT designed for embedment. These have only a thin layer of plastic and a heating element that is THHN/THWN wire. This wire is intended for interior use NOT in concrete, asphalt, or under pavers.” Don’t be fooled by Warmzone’s misleading and inaccurate statements. All low or high voltage heating element have protection insulators made of materials that look like plastic but actually they are PVC, or HDPD. Tuff Cable has been melting snow, warming floors and heating spaces for over 30 years, so don’t tell it or the happy customers that it serves, that it wasn’t designed to be embedded. Heatizon Systems Cozy Heat, Floorizwarm, Hott-Wire and Tuff Cable heating elements are all listed, come with industry leading warranties and have been tried and proven for many years. Just goes to show you how little some companies selling Radiant Heat and Snow Melt products really know about Radiant Heating Products.

The fact of the matter is that both low voltage and high voltage snow melt and floor heating cables can be damaged and both are designed to be embedded into a material that will draw the heat away from them resulting in a nice even heat across the surface. In the event either low voltage or high voltage cables are damaged both can be repaired. Low voltage cables tend to be much easier to repair because they do not have a shield to contend with.

Warmzone’s “Myth 2: Low voltage radiant systems cost less to run than a line voltage system.”

Fact 2:

To the extent low and high voltage electric Radiant Heating and Snow Melting cables are designed to deliver the same, and the correct, amount of energy to the surface and, provided they are activated in an identical environmentally friendly fashion, the energy consumption is identical.

Heatizon Systems’ low voltage products typically are energy misers because they are easy to customize to deliver the perfect amount of heating or melting energy to the floor or slab and because their output can be changed by the length of the heating element, the spacing between runs of the heating element and the size and tap of the transformer. All line or high voltage electric Radiant Heating and Snow Melting cables, except for Gutter Melt SR, Hott-Wire SR and other Self Regulating Cables, are designed to deliver a fixed wattage per linear foot so the energy per square foot delivered to the floor or slab can only be customized by increasing or decreasing the space between the lengths of cable.

Self Regulating Cables, like Heatizon Systems’ GutterMelt SR and Hott-Wire SR Heating Cable, are designed to deliver fixed wattage at a certain temperature within a medium such as air, ice water, concrete, etc. The watts per square foot delivered by Self Regulating Heating Cables can be adjusted by changing the spacing between the lengths of cable in a manner similar to other line or high voltage products.

In many high voltage applications the dedicated electrical service and thus the energy consumption is greater than it needs to be because the project is designed around the output of the heating cable instead of heating cable being designed to serve the ASHRAE requirements of the project. Heatizon Systems and its Distributors are trained to design and help you select the low or high voltage products that will best satisfy the needs of your project and keep the energy consumption to a minimum.

Warmzone’s “Myth 3: Low voltage systems are easier to repair. Both line voltage and low voltage cables are easy to repair. Simply remove the bad section of cable, add in a splice kit, cover it back over with whatever surface it’s in, and the system should operate as normal.”

Fact 3:

Warmzone is correct in that both low and high or line voltage cables are repairable. However, the presence of a ground shield on all high voltage cables makes repairing them more time consuming and difficult.

Warmzone states: “Low voltage systems are NOT more efficient.” Properly designed and installed low voltage and high voltage electric Radiant Heating and Snow Melting products are nearly 100 percent efficient. As a result of the high efficiency of these products, correct design and installation becomes essential in order to minimize energy consumption and costs. Heatizon Systems and its distributors design all of Radiant Snow Melting projects in North America to the American Society of Heating, Refrigeration and Air Conditioning Engineers (“ASHRAE”) Standards and all Radiant Space Heating projects are designed to the requirements of an objective Heat Load or Heat Loss Calculation.

Heatizon Systems provides Design and Installation Instructions with all of its products and calls for them to be installed per the National Electric Code (“NEC”) in the U.S. and the Canadian Electric Code (“CEC”) in Canada.

Warmzone “Myth 4: Low voltage systems offer a better warranty.”

Fact 4:

Heatizon Systems backs its products with, no gimmick, straight forward, and industry leading warranties. We challenge you to find a better warranty to cover your investment.

Unfortunately some of Heatizon Systems competitors prefer gimmicks like: “one year extendable to 10 years” if you do this, that and the other, or “covers 5 times the cost of the cable” if you return it to a foreign country for verification that it is defective. Once again Heatizon Systems backs its products with, no gimmick, straight forward, and industry leading warranties. If you prefer one with gimmicks be sure and call us once you discover you need a Hott-Wire or Tuff Cable retro-fit to replace our competitors failed cable or deny your warranty claim.

Warmzone states: “Some low voltage warranties are very deceiving. They boast a 25 year warranty period, but when examined closer it is found that the 25 year warranty only covers the heating wire.” What is the point of this very interesting statement? Is Warmzone, an internet marketing company and not a manufacturer, saying that the manufacturers of the line voltage products that it markets warrant more than the heating cables? This I need to see with my own eyes and you should too!

Warmzone’s “Myth 5: Both systems provide sufficient heat.”

Fact 5:

Properly designed low voltage and line voltage products provide sufficient heat to satisfy ASHRAE’s design requirements for snow melting and the Heat Load requirements for building heating.

Warmzone’s “Myth 6: Low voltage systems in most snow melting applications do not meet the ASHRAE standards.”

Fact 6:

Unfortunately, it appears that Warmzone does not understand Heatizon Systems’ low voltage technologies and that it either has not read or does not understand the portion of ASHRAE Handbook that deals with “Snow Melting and Freeze Protection”.

In the event Warmzone understood Heatizon Systems’ Tuff Cable Snow Melt Products it would know that it can deliver up to 24 watts per square foot when installed on 6 inch centers, up to 36 watts per square foot on 4 inch centers and up to 48 watts per square foot on 3 inch centers.

ASHRAE is a very valuable design tool which indicates the watts/Btu needed to melt snow in certain geographic locations and suggests maximum spacing between heating cables. ASHRAE does not differentiate between low and high voltage cables. Heatizon Systems offers a variety of low voltage and high or line voltage Radiant Snow Melting Cables to its discriminating customers.

Warmzone’s “Myth 7: Both systems are UL Approved.”

Fact 7:

Heatizon Systems low and high voltage Radiant Snow Melt, Radiant Floor Warming, Radiant Roof Snow and Ice Melting and Radiant Space Heating products are all Listed to UL Standards and Certified to CSA Standards by Intertek a Nationally Recognized Testing Laboratory equivalent to UL and CSA. Each of Heatizon Systems’ Authorizations to Mark is available for download at www.Heatizon.com. Heatizon Systems makes its Authorizations to Mark easily available and it encourages other manufacturers to do as well.

Warmzone states: “Make sure to do thorough research before purchasing any products, which means checking for proper safety certifications and standards, and you won’t regret it.” Heatizon Systems agrees that you will never regret purchasing one of its line and low voltage products because all of them have earned the right to be listed to UL Standards and Certified to CSA Standards.

These companies do not make any of the products that they sell and the revolving portfolio of products that they carry make it imperative that their prospective customers fully understand why the suggested product is the best solution for their needs and exactly who stands behind the warranty. By failing to be an informed customer you may be satisfying the profit and other objectives of the supplier rather than the exacting needs and requirements of your project. As a buyer, you do not want your purchase decision to be based on recommendations, and/or suggestions motivated more by profit margin than by the long term satisfaction of you, the customer.

Tired of Shoveling Your Driveway?

Outdoor Snowmelt Systems are becoming more popular

By Ann Robinson and Annie Schwemmer

December 14, 2007

Did you ever hear your dad say, “Shut that door! Are you trying to heat the whole outdoors?”

Well, today a whole industry has sprung up with just that goal in mind.

Several factors contribute to the rise of outdoor heating technology: First, we are living outside more these days in outdoor rooms and kitchens.

Also, it seems people have less time for shoveling or just prefer to get exercise in the controlled atmosphere of a gym instead of hard labor. Finally, there is a greater emphasis on making and keeping our homes and businesses safe and accessible for all members of society.

Heating your driveway is one of the most popular outdoor heating applications with obvious advantages, especially in the midst of a Utah winter

Driveway stays free of ice and snow with heating system. There are two basic choices — electric cable or hot water systems. (Heatizon)

There are two basic choices for driveway heating — electric cable or hot water systems. You cannot add such a system to an existing concrete driveway without completely removing and replacing it. Snowmelt systems can be used with a variety of materials including concrete, asphalt or pavers, though concrete is usually the material of choice.

There are three main elements of a snowmelt system — the heating element, the controller and the activation device. The heating element can be either electric cables or piping/tubing that circulates hot water. The controller is a wall-mounted control box for electric systems or a boiler for hydronic (hot water) systems. Hydronic systems also require other parts like pumps and manifolds needed to operate the system. Both types use either manual or automatic activation devices.
Manual devices are simply on/off switches and are less effective because they may not always be started before the storm arrives.

Automatic sensors include aerial-mounted and pavement-mounted snow switches. These sensors activate the system when there is moisture present and when the temperature drops below 38 degrees. Since automatic systems run continuously at low levels, they respond more quickly to a storm than the all-on/all-off approach of the manual start systems.

When a new concrete driveway is installed, steel reinforcing bars are placed throughout the area to strengthen the concrete and to prevent cracking and settling in the new drive. The heating elements of the snowmelt system (cables or piping) are set on top of the wire mat prior to the concrete pour. It is possible for a homeowner to install this piping or cabling, though, in the words of one manufacturer, it requires an “ambitious” do-it-yourselfer. Connecting the heating element to the controller will most likely require the help of an electrician or plumber, depending on the type of system.

The controlling system must be installed in an area protected from the elements, often a basement or garage. The water-based system, including a boiler and manifold system, requires more room than an electric system and will need an area from 4 feet to 8 feet in diameter.

The cost of a snowmelt system ranges between $12 and $21 per square foot of area heated. Factors that affect the final cost include: whether or not you must remove an existing driveway; the price of concrete (which varies depending on the location of the project and market demand); the installation labor; what type of control system you select, and the size of the system required. Obviously, while you are at it, you can also heat sidewalks, ramps and exterior stairs if you want an entirely maintenance-free design. The cost of operating such a system is approximately $0.28 per 100 square feet per hour.

There are other options for outdoor heating that we will discuss next week. Remember that while pricey, the advantages of a snowmelt system extend beyond never having to shovel. Your home will reap additional benefits such as never again having anyone get stuck in your driveway, providing a much safer, slip-free situation, avoiding the use of environmentally damaging chemicals and adding value for resale.
