Are You Familiar with all the Home Heating Products Available?

December 12, 2008 00:12 AM  BY  STACEY BARRUS

We’d risk a guess that a majority of homeowners are probably most familiar with forced air unit heaters and might not realize that there are other options for heating a home – other options that are more efficient and even more comfortable. One such option is radiant floor heating, which, as opposed to warm air systems, delivers the source of heat upwards from the floor level, not from the ceiling. Radiant heaters or radiant energy is the oldest form of heating used to provide comfort and is the basis for all heating systems. Radiant energy is heat efficiently radiating outwards, and is absorbed by an object without physical contact with the heat source or by heating the surrounding air, as is the case with convective, forced air systems.

It might be hard to believe, but under floor heat was first used by the Romans. While under floor heating was initially reserved for the rich, it eventually became increasingly commonplace in public buildings and villas. This form of radiant heating was used particularly in the colder regions of the Roman Empire. The Roman system was based on hypocausts, comprising ducts that underlay the floor (itself built on raised brick piles) and flues that were built into walls. Hot air or steam from fires circulated up through this system, warming the floor and walls, with heat passing into the rooms.

If you’re looking for efficient, comfortable heat for your home, radiant floor heating could the solution you’ve been looking for.

Perfect Climate for Comfort

December 21, 2008 00:12 AM  BY  STACEY BARRUS

In today’s volatile and topsy-turvy housing market, it’s not a bad idea to add value to your home in new and innovative ways.Don’t just think about renovating a bathroom, consider using radiant heaters to warm towel racks in the bathroom, or a heated floor.Can you think of anything cozier on a chilly winter morning than toasty toes when you step out of the shower?

Not only is radiant heating is one of the most comfortable ways to heat your home, but radiant heaters also offer a surprisingly wide diversity of applications. Radiant heaters can be used in a number of applications, including in tiled areas, hardwood flooring, carpeted areas, cement floors, basements, and garages.

Radiant heaters are a type of heater that warms objects instead of air. Radiant heat uses objects, such as the floor, to heat a home. The air in the room is warmed when it comes into contact with the warmed objects. Heat loss is reduced and the radiant heat remains in the lower part of the room, warmer near feet level and slightly less so at head level, creating the perfect climate for comfort.

Radiant Heaters Tip: The variety of high efficiency boilers or electric radiant floor systems makes radiant heat one of your most efficient ways to heat your home.

Are You Looking for Radiant Heating?

December 19, 2008 00:12 AM  BY  STACEY BARRUS

Sometimes can be hard to narrow down what kind of radiant heaters to install. There are dozens of products available to purchase, and there are even more companies telling you that their product is the best.

For many homeowners, electric cable heating systems, often called line- or high-voltage systems, are gaining popularity and are ideal for heating smaller areas like bathrooms, kitchens, and sun rooms. These systems are comprised of a thermostat and a heating cable. These radiant heater systems are oftentimes less expensive, and give the ability to customize a layout that will heat every square inch of your floor.

Every available radiant heater cable system is equally effective, so when determining which system to purchase, you should look at the warranty of the product, along with the ease of installation. Some cables must be embedded in a separate layer of concrete or mortar, whereas other systems can simply be installed in the thinset. Most radiant heater cable systems can only be installed under tile. However, on others, if the cable is embedded in mortar or concrete, any flooring can be installed on top of the concrete.

Radiant Heaters Tip: When heating smaller areas, it is nearly impossible to beat the simplicity and price of an electric cable radiant heating system.

Learn About the Options

November 29, 2008 00:11 AM  BY  STACEY BARRUS

With the current housing market being so unpredictable, we’re seeing an increasing number of homeowners are opting to stay put in their homes, rather than buy a new home. They find that one way to make their current home a better fit for them is to remodel the kitchen or bathroom, or upgrade the home’s heating systems. While there isn’t a single heating system out there that is an ideal fit for every project, there is an ideal system for every project. Warmzone.com can provide you with the heating systems you desire, as well as consult with you on which systems would be the best fit for your project.

Hydronic under floor heating systems are some of the most popular forms of radiant heat. In the most recent hydronic heating systems, PEX radiant tubing has been installed in a concrete mass called Gypsum Concrete or “Gypcrete.” This method of heating system installation works very well in most applications, but there have been developments in the installation process of hydronic under floor heating that make it easier to install for certain situations. This new development is known as a low-mass or modular board underlayment system. Rather than embedding the hot water tubing in concrete, the PEX tubing is laid in the grooves of pre-cut wood panels. This new method is ideal for remodeling and most new construction projects.

Heating System Tip: The hydronic under-floor heating system was first used by the Romans; there have obviously been significant developments since that time.

Which Radiant Heating System Should You Choose?

December 28, 2008 00:12 AM  BY  STACEY BARRUS

If you are looking to warm your floors with radiant heaters and are trying to research what kind of radiant heaters to install you might find yourself scratching your head at this point. There are dozens of products available to purchase, and there are even more companies telling you that their product is the best.

So which product is the best? Should you install a hydronic heating system that pumps hot water through your floors, an electric cable heating system, or a low-voltage screen system? The answer lies in the type of project you are doing. Not every system is ideal for every project, but there is an ideal system for every project.

Hydronic Heating Systems   

Hydronic floor heating is the oldest and most popular type of radiant floor heating. These systems are comprised of a boiler or hot water heater, pumps, manifolds, PEX tubing, thermostat, and either gypcrete (a concrete-like material) or wood panels. Hydronic heating is the most complex of all radiant heat systems. These systems require trained professionals to design and perform the installation. Your best economies of scale are achieved for hydronic systems in large areas or entire homes because of their expensive components and operational costs.  Hydronic systems can be installed under any type of flooring. Most hydronic systems require hot water tubing to be installed in a 2-4″ bed of light concrete and are best installed during the initial construction because of its weight load demands and adjustments to floor height. Recent low-mass products have been developed to avoid these challenges by fitting the tubing into pre-cut wood panels, making hydronic systems more convenient and possible for most major remodeling projects.

 If you want to heat smaller areas like a bathroom or kitchen, a hydronic floor heating system may not be the best value for your project. The complexity and cost of installing the system, along with the long-term maintenance and up-keep required, is not worth the small amount you will save in operational costs.

Electric Cable Heating

Electric cable heating systems, often called line- or high-voltage systems, are gaining popularity and are ideal for heating smaller areas (10-300 square feet) like bathrooms, kitchens, and sun rooms. These systems are comprised of a thermostat and a heating cable. On some systems, the cable will be shipped to you as a large spool of cable. These systems are oftentimes less expensive, and give you the ability to space the cable how you want and customize a layout that will heat every square inch of your floor. Other systems have the cable attached to a plastic mesh or tape to create a mat to maintain its proper spacing.

Every available cable system is equally effective, so when determining which system to purchase, you should look at the warranty of the product, along with the ease of installation. Some cables must be embedded in a separate layer of concrete or mortar, whereas other systems can simply be installed in the thinset. Most cable systems can only be installed under tile. However, on others, if the cable is embedded in mortar or concrete, any flooring can be installed on top of the concrete. When heating smaller areas, it is nearly impossible to beat the simplicity and price of an electric cable heating system.

Radiant Heating Can Improve the Air Quality of Your Home

December 24, 2008 00:12 AM  BY  STACEY BARRUS

What a pain! If you or anyone in your family has asthma or dust allergies, you know all too well how miserable these ailments can make a person. Many allergy and asthma experts will advise certain changes in housekeeping habits to help alleviate allergy- or asthma-causing conditions in your home. In addition, you might consider changing your heat source to radiant heaters.

At first glance, you might not think that radiant heaters could be such a simple solution to helping keep your home healthy. In reality, radiant heaters improve the air quality, which is important, especially for anyone who suffers from either dust allergies or asthma. Not having to change air filters or clean heating ducts should also cut down dramatically on dust or other allergens in your home’s air.

Eliminating dust mites that live in your home would also go a long way towards helping keep your home healthy. Since dust mites love a warm moist environment, towel heaters and other radiant heater systems aid in maintaining a consistent room temperature and keep it moisture-free…and dust mite-free, too.  Furthermore, mold and mildew are also caused from excessive moisture especially in bathrooms with insufficient ventilation.

Radiant Heater Tip: By placing radiant heaters or a radiant heat towel rack in the bathroom you can combat the spread of germs for only pennies a day.

Warranties Are Not Created Equal

December 29, 2008 00:12 AM  BY  ROBERT COHEN

The Mystery Warranty

How much do you really know about the warranties offered by manufacturers? Sure it may say “25 Year Warranty” on the package, but what exactly does that mean? Most manufacturers of radiant heating systems offer a warranty, but a 25 year warranty isn’t always better than a 10 year warranty and this is why:

I chose the Danfoss GX electric radiant heat cables to build an asphalt heated driveway at my residence. The heat of the asphalt combined with heavy weight, caused me to wonder how the GX cables were going to hold up, and what would happen if a problem occurred. I was pleased to discover that Danfoss products have a 10 year warranty, that covers up to 5 times the cost of original installation. Why is this exciting? Because the failure of a radiant heating system isn’t like a vacuum cleaner breaking down, you can’t throw it in your car and bring it back to the store for a refund. Fixing a severed cable requires tearing up the surface of the driveway – or in the case of indoor radiant heating, tearing up your brand new tiles or wood flooring. The process of tearing up a floor or driveway is time consuming and costly, not to mention annoying. Many manufacturers will replace the bad product, but you still have to pay out of your own pocket to tear up the floor and hire someone to fix the problem.

Danfoss is so sure that you won’t have any problems, their warranty is the best offered by radiant heat manufacturers. Not only do you get brand new Danfoss product, but they will cover the cost of floor removal, and reinstallation (up to 5 times the cost of the original installation). So when you install your radiant floor or driveway, you can rest easy knowing that unexpected problems are already covered.

The Myths of Low Voltage versus Line Voltage Radiant Systems

November 06, 2008 00:11 AM  BY  WARMZONE

There has been much debate over low voltage radiant systems versus line voltage radiant systems as radiant heat gains popularity in North America. The aim of this article is to dispel some of the myths surrounding the different kinds of systems.

Myth 1: Low voltage radiant systems are safer than line voltage.

Low voltage is low, so it makes sense that it’s safer, right? While this makes perfect sense initially, we have to take a closer look to find out the real answer. If your definition of safe is the chances of being hurt by voltage during installation, low voltage will give you a bit of a shock, but won’t cause lasting damage. The real question we should be asking is how durable is the cable against damage and how well is the cable insulated. Both line and low voltage snow melting systems are embedded in 4 inches of concrete, asphalt, or under pavers. When installed properly the embedded systems are not exposed and harmful. 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. Low voltage wires do not have ground fault protection, so electrical leakage can go undetected.

In contrast, line voltage obviously has higher voltage, which is why line voltage cables are built to withstand wear and tear, and are much more difficult to damage. If you do manage to damage a line voltage cable, don’t worry! Line voltage systems are equipped with ground fault protection (GFEP) breakers with a 30 milliamp trip. Which means the system will automatically shut off when it has reached beyond allowable leakage levels. What does this mean? Well for one you don’t need to worry about bodily harm, but you also don’t need to worry about potential fire hazard from a damaged cable. The bottom line: both line voltage and low voltage systems are safe to use.

Myth 2: Low voltage radiant systems cost less to run than a line voltage system.

It is true that low voltage radiant systems consume a lower amount of power, but this doesn’t mean it is less costly to run. Low voltage systems can actually be more expensive to operate because these systems generally produce 20 watts/sq ft (which is below ASHRAE standards). By producing less heat per square foot, it takes longer to heat the same area, thus increasing the cost and the time it takes to melt. Because of the decreased heat output, during heavier snow falls low voltage systems struggle to keep up with the snowfall, and have to remain on much longer. For this reason, ASHRAE has set forth watt standards for snow melting.

Line voltage systems are designed specifically for the environment in which they will be operating. These systems are made to produce the necessary watts (that meet ASHRAE standards) to melt snow in the most efficient time possible.

Zmesh installation beneath hardwood flooringSome low voltage systems on the market have some distinct advantages over line voltage. Zmesh is low voltage, but does not rely on heat cables to generate heat. Instead it is constructed of a unique thin mesh that requires no embedding in thinset and can be installed directly under carpet pad, hardwood and even for use on your roof for snow and ice melting. The biggest advantage of Zmesh is that you can hammer nails into it without worry of damage!

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. You do not have to replace the entire cable or rip out the entire surface, only the area that is damaged. The location of the break can be identified by using devices such as the DEVItrace from Danfoss or a TDR, which uses radio frequencies and a “wand” to locate the damaged section of cable.

Myth 4: Low Voltage systems are more efficient.

Low voltage systems are NOT more efficient. Since these systems have a much lower output of heat per square foot; they take much longer to melt snow, especially during heavy snow storms and probably will not be able to keep up with the demand. Further increasing their inefficiencies, low voltage systems must have the electricity pass through a transformer and very thick power leads (2 gauge), which causes voltage to drop as it travels distance before reaching the heating element. Line voltage cables have the energy to go directly into heating, without the loss of power. Overall, both line and low voltage systems are more efficient than hydronic snow melting.

Myth 5: Low voltage systems offer a better warranty.

Some low voltage warranties are very deceiving. They boast of a 25 year warranty period, but when examined closer it is found that the 25 year warranty only covers the heating wire. As discussed earlier these heating wires are actually THHN or THWN, which can be purchased relatively cheaply at any hardware store.

Warmzone’s line voltage cable manufacturer’s warranty (Danfoss) covers up five times the cost of the original system which is intended to cover the cost and time involved in making repairs, not just the actual heating element itself.

Myth 6: Both systems provide sufficient heat.

Low voltage systems in most snow melting applications do not meet the ASHRAE standards. The minimum watts per square foot ASHRAE requires in North America is 32 watts per square foot. Popular low voltage systems on average are designed to produce approximately 20 watts per square foot and with extremely tight spacing will max out at 30, still below the standards ASHRAE has set forth.

Line voltage systems are designed specifically for the environment in which they will be operating. These systems are made to produce the necessary watts (that meet ASHRAE standards) to melt snow in the most efficient time possible.

Myth 7: Both systems are UL Approved.

Most low voltage snow melting systems are not UL listed. Warmzone’s line voltage systems are UL tested and approved.

SYSTEM WEAKNESSES

  • THHN/THWN wire was not designed for concrete embedding. The outer jacket is soft and easily cut which will shorten its life.
  • Low heat output – Does not satisfy ASHRAE requirements.
  • Bulky and costly controls (transformer and control box are 100 lbs per 200 square foot zone).
  • Warranty - only covers THHN/THWN wire. Control box is 1 year, transformer is 5 years.
  • Slow to install - the transformer and control box are complicated and time consuming to install.
  • Noise – transformers emit noise and location of them must be considered.
  • Price – low-voltage systems are typically double the price of a comparable line –voltage system.

As radiant heating systems have gained popularity, a lot of fly-by-night manufacturers are trying to cash in on the recent boom. This sparked ASHRAE to come out with standards for radiant snow melting systems to prevent abuse from manufacturers. Most low voltage radiant snow melting systems don’t meet the ASHRAE standards for quality and efficiency. Unfortunately, not all consumers are aware of standards in the radiant industry and purchase faulty products unwittingly and end up with negativity towards radiant heating in general. Rest assured there are plenty of efficient radiant systems that will run smoothly for decades without needing any maintenance. 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.

Buying from Warmzone Makes Sense

August 07, 2007 00:08 AM  BY  WARMZONE

Upon hearing the words, “What can Brown do for You? ®” an immediate vision comes to mind of a large, brown delivery truck with the name UPS emblazoned on each side. United Parcel Service has done an incredible job to bring their name to the forefront in the package-delivery market.  The same might be said regarding “The Golden Arches ®,” McDonald’s famous advertising ploy.  Most highly-successful businesses are easily recognized by a catchy slogan or an eye-catching symbol.

We at Warmzone want to be known in the radiant heat arena as the company that will do everything possible to “just make sense” of what might be a confusing array of possibilities for consumers who are seeking information on alternative heating sources.

Why are such vast numbers seeking an alternative radiant heating source ?

Questar Gas Company, included the following message with January’s fuel bill mailing:  “As you have seen, natural gas bills this winter are significantly higher than last year.  Even with all the news about higher natural gas prices, reality doesn’t set in until your bill is opened.”  Unless customers have been oblivious to drastic increases in fuel costs over the past two months, this was somewhat of an understatement.  More than just reality has set in upon consumers!  Caught somewhere in the middle of paying a huge fuel bill and taking a sick child to see a doctor, people are taking a stand against such increases. 

President Bush has encouraged our nation to look for alternative sources as we have become “addicted to oil.” In his state of the union address on January 31, 2006 he announced the Advanced Energy Initiative, a 22% increase in clean-energy research at the Department of Energy, “to push for breakthroughs in two vital areas. To change how we power our homes and offices, we will invest more in zero-emission coal-fired plants, revolutionary solar and wind technologies, and clean, safe nuclear energy.”  Quoting once more from the Questar message: “As you can see, prices on the open market are volatile and have increased to record highs this year both nationally and locally.” 

Volatile, skyrocketing, record high fuel costs provide reasons aplenty for so many people to turn to Warmzone.com for guidance in finding the best-possible radiant heat system for their needs.  Consumers are finding themselves backed into a corner and are looking for an efficient, comfortable alternative.  That just makes sense!

With our commitment to researching the best options for radiant heat and assessing each job individually, our research and design team is prepared to design each project with the ideal system to meet the needs of our customers at the best available prices.

Warmzone is a different kind of company.  Unlike a manufacturer, we do not favor one system over another.  We acknowledge the fact that there are dozens of brands and types of radiant systems that offer unique qualities, but no one system is the answer for every project.  We take great interest in your project goals, requirements and budget and then provide you with a quote for the best system available to complete your project.  We may suggest using an electric, hydronic or a combination of these technologies.  There are clear advantages and disadvantages to each system and technology.  We will explain why we prefer one system over another for your particular project.  At Warmzone.com, you can expect simple, honest explanations for our suggestions to you. 

Customer service is at the top of our priority list.  As with “Brown” or the “Golden Arches,” we would be nothing without you, the consumer.  We are committed to helping people install the latest in innovative radiant heat systems by providing:
            1.  High quality materials
            2.  Installation packages that simplify the work.
            3.  Design assistance
            4.  Installation advice and support.
            5.  The latest ideas in energy efficiency and alternative energy.
We are not satisfied until you are satisfied.  That, of course, makes perfect sense!

Radiant heat systems are constantly evolving – which can be a challenge when it comes to deciding which is the best system for your project.  You can be assured that Warmzone will consider every system and then offer you the best technology for your project.

Most of the systems we design and sell can easily be installed by any plumbing and heating professional or general contractor.  But if you cannot find either professional in your area, our products can be installed by any reasonably-competent handyman.  Custom design and engineering packages are also available to assure that you are getting off on the right foot with your heating investment. These plans take the guess work out of the installation and become a road map for your system for future reference or to pass on to the next home owner.  

We welcome your inquiries and are prepared to help you with your radiant heat decisions.   Warmzone is the only company matching individual heating projects to solutions that make sense among the wide variety of available choices.  We’re not “brown,” nor are we “gold,” but we are leading out to assure customers make the right choice in the ever-increasing radiant heating market.
