Radiant Heating 101

The number of types of radiant heating systems available for residences or businesses is awfully mind-boggling. There’s really a lot of selection for homeowners to choose from. Today we’ll discuss the electric cable heating system kind of radiant heaters.

Electric cable heating systems are gaining popularity in as radiant floor heating systems 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 radiant heating 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.

Low Profile, Electric Underfloor Heat

Efficient, Discreet Radiant Heat

Radiant heat has been around many years now for very good reasons. Electric underfloor heating is just plain hard to beat when it comes to ways of providing efficient heat for your home or business. I’m sure you have heard of heated floor technology by now. Rows of heat cable, mats or other heating elements are laid out on the subfloor and the finish surface is applied over that. ComfortTile floor heating cable is a proven, and commonly chosen radiant heat system that is easy to install, and has become the workhorse of radiant heating systems. ComfortTile systems offer a single point connection, allowing you to connect one end to the thermostat and be done. No need to “loop” or connect the other end to a controller.

FoilHeat and FloorHeat are also excellent choices when there is need to keep the profile extremely low. Both floor heating systems are almost paper thin, and the low profile also makes FloorHeat idea for discreet roof heating systems (aka, RoofHeat STEP). Both FoilHeat and FloorHeat systems come in rolls that are conveniently rolled out for easy installation. Virtually any finish surface can be applied over the top. The FloorHeat system is also a low-voltage, self-regulating floor heating system.

One of the nice features of a radiant heated floor system is that you program or control zones separately, so you can shut down any rooms that you aren’t using. There is not a more comfortable and energy-efficient heat solution than an electric radiant floor heating system. It’s simply a heat that can’t be beat.

Back on Track with a Heated Driveway

Heated Driveway System in Illinois Paves the Way to Big Savings for one Warmzone Customer

When a Warmzone customer in rural Illinois found he did not have the resources to heat his entire driveway as originally planned, Sales Manager, Bryan Morris, offered a reasonable alternative. “Tire tracks were a great option in this scenario,” he explained, “because you can still get a heated portion that allows you to drive in and out, without breaking the bank. After consulting with the customer and our design team, we laid out the options (verbally and with drawings) before deciding on a more cost-effective, two-track heated driveway solution. Ultimately, heating two tire tracks (500 sq.ft.), as opposed to heating the entire 1,250 sq.ft. driveway, resulted in a $3,900 cost savings.”

Another consideration was the lack of available power. “To heat an entire driveway would have required a large number of amps from the home’s electrical power panel,” Morris stated. “Most homes only have a 200 amp panel, yet it takes approximately 180 breaker amps per 1,000 square feet to heat an entire driveway.”

The two-track radiant heated driveway system required installation of four Warmzone ClearZone snow melting mats, a 200-amp Warmzone electrical timer panel, an aerial mounted moisture/temperature snow sensor, a remote manual control unit and an NEC marker plate. Tire tracks were easily installed by rolling out the mats like sleeping bags. A protective asphalt layer was then raked over the tire track mats (photo 2) before the final surface coat was applied. “We use an asphalt machine that straddles the heating element to prevent damaging the heat cable,” offered Morris.

The great news is that you don’t have to pour a new driveway to benefit from a heated driveway. Warmzone can customize your system to fit your needs and budget. “On this project,” said Morris, “the customer was paving the whole driveway anyway. Some customers pick other install methods, such as saw cutting, to achieve their goals.”

Saw cutting is cutting grooves or paths and inserting the heat cable in areas where heat is desired. With certain driveway heating systems, it is also possible to pave over the mats and create the appearance of a seamless transaction. “You can cut out the area you want to heat and then pave only that area,” Morris added. ClearZone is used under cement, asphalt and pavers on a regular basis.

Flexible options make heated driveway solutions a very popular equity booster for homeowners, and are becoming a popular home improvement option. “On average,” Morris stated, “the overall materials (cable, electrical and auto sensors) cost $6.00 per sq.ft. for 1,000 sq. ft., and the operating cost per 5-hour storm is $18.00, or $3-4 per hour depending on the state the heated driveway system is installed in and the power company’s cost per kilowatt hour.”

While the initial cost of installing a radiant heated driveway system may seem a bit daunting, the benefits of driveway heating are well worth the initial investment, the most obvious being convenience. Heated driveways don’t require shoveling, harmful salt and chemical applications or expensive snow removal services. Instead, driveway heating systems provide a safe, thorough snow removal solution with curb appeal, solving snow  removal challenges posed by problematic driveways, steps, and other heavy traffic areas.

Heated driveway systems are fully automated, so they will automatically turn on or off when needed. “If it snows at 3 a.m.,” Morris smiled, “our customer will wake up to a clear driveway. He now has a reliable, efficient snow removal solution.”

Project Spotlight – Colorado Homeowners Install Solar Powered Radiant Floor Heating System

When two Colorado homeowners decided to build a new home from the ground up, they had two main objectives in mind. They wanted a home just for them and they wanted to be as eco-friendly as possible. One of the components they chose in their new construction was to install radiant floor heating through the 1600 square feet downstairs and 900 square feet upstairs.

After doing some research and finding Warmzone online they were pleased with the many options available for various applications and the customer support offered during the entire process.

These Rocky Mountain homeowners had several great reasons for wanting to go the radiant heat route. A major consideration was allergies and how forced air systems exacerbate this condition. Cost was another concern, as was the noise of a running furnace and the desire for a comfortable, even-air temperature throughout the home. Many customers are finding their way to radiant floor heating for some of the same well thought-out reasons.

Installing radiant floor heating cable

In order to accommodate the necessary electricity needs for a radiant floor, they installed 28 solar panels to meet the demand of the electric heat. This means they are using electricity solely produced by them, helping to keep costs down and mother earth smiling.

This project called for ComfortTile heat cables and a low-voltage floor heating system laid under a variety of flooring throughout the home. The Colorado couple chose tile, wood laminate, and carpet in various parts of the home. The radiant flooring systems were chosen because of their particular capabilities and installed throughout different zones. Warmzone provided the design layouts and helped walk them through the entire process.

When asked about the benefits of using radiant floor heating, the homeowner produced a long list, including evenly spread heat through the whole house, toasty floors, noiseless heating system with easy-to-program thermostats, lack of dust, and no need to wear shoes indoors anymore.

Asked if they would recommend radiant floor heating to others Jane responded, “Definitely! Check out the different flooring options and applications and determine where you want the zoned heating.” Warmzone provides customers with a variety of options and helps you select the best solution for your home and budget.  Warmzone prices, product offerings and professional design services are among the best in the industry.

Radiant Heaters

Radiant heating, as opposed to warm air systems (such as a forced air unit heaters), deliver the source of heat to the floor level, not the ceiling. And since warm air rises, heating the floors proves to be the most efficient means of heating living areas.

Radiant floor heating or radiant energy is the oldest form of heating used to provide comfort and is the basis for all heating systems. Radiant energy is totally pure radiation 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.

Under floor heaters were first used by the Romans. Initially the preserve of the rich, under floor heating became increasingly commonplace in public buildings and villas, 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.

More specifically, the floor was laid out as series of concrete slabs acting as radiant heaters supported by columns of layered tiles, with a furnace at the bottom of one exterior wall. By placing the fire here, the draught would take the radiant heat under the floor, and up through the walls to radiant heater chimneys located in the corners of the room.

Today we recognize the brilliance of the Romans and Koreans as early adopters of radiant heating, as the technology is still a desired method for delivering comfortable and efficient heat in our homes. Now we have radiant heaters using electric resistance cables that are constructed of highly rated materials and feature manufacturer warranties of up to 25 years.

Home Improvements for Your Feet and Your Pocket

A Smart Choice for Increasing Your Home’s Value

As the housing market crash continues, it seems that even the falling prices, incentives and rebates still aren’t enough to entice new buyers. A year ago a finished home would sell in 4.3 months, it now takes an average of 6.3 months. If you are already a home owner, switching your home from fossil fuel heating to electric radiant heat will not only help protect your investment, but provide an earth friendly efficient alternative that will make your home more attractive to potential buyers.

The best choice for radiant heating is the ComfortTile cable and mats. The CT systems continue to be Warmzone’s best selling electric heat product, and it’s no wonder considering Warmzone attaches a 10-year warranty to every system sold.

This system is the most robust radiant heating product on the market and is manufactured by an industry leader that has been providing quality products for decades.

The most popular spaces for radiant heat in the home are the kitchen and bathroom areas. These areas tend to be the largest area of tile in the home, which also makes it the most difficult to heat. Forced air heating systems only warm the air, which leaves the floors cold and drafty during cold weather months. Radiant heat provides a uniform temperature from ceiling to the floor and warms all the objects and furniture it contacts.

The ComfortTile radiant heating mats are the easiest systems to install. They arrive with the ComfortTile cable already affixed to the flexible mesh, which has a convenient, easy-to-use adhesive backing.

Warmzone’s website is filled with information about how to best install the product beneath tile, stone, and concrete applications. We also have a full staff of professionals available to help you through every step if you choose to install the system yourself. If installing it yourself isn’t your thing, Warmzone has a network of installation professionals in your area that are experienced installers of our systems.

Warmzone has now made the ComfortTile mats more affordable than ever, making it easier for everyone to enjoy the warmth of radiant heating in their homes. Now is the best time to start remodel projects and ready your home for the upcoming winter months, especially if you are pouring new concrete.

Project Highlight – University of Minnesota

Warmzone was recently approached by the Forestry Resources Department of the University of Minnesota, Twin Cities, with a horticulture study that needed Warmzone’s help. The solution: ClearZone radiant heating cables.

The University purchased 46 reels of ClearZone heat cable to measure growth variations in different temperature plots. University officials chose the ClearZone system because of the easy-to-program thermostat, versatility and high durability in outdoor conditions.

The radiant heat system enabled Forestry Department students and faculty to create controlled environments in which to conduct accurate growth rate studies.

The predominant outdoor use for the ClearZone system is to heat driveways, parking lots, sidewalks and bridges. It is especially useful on disability ramps, where safety and ease of use is most important.

In the past, radiant heat systems have been viewed as a luxury that only a few could obtain. But that’s changing. More and more consumers living in cold regions are discovering that the benefits of radiant heating far outweigh the initial cost.

The study by the University has opened up new avenues for radiant heating that have never been used before. Although still a new concept, the study proves that radiant heat has the potential to be used by home and garden enthusiasts to create a tropical oasis in just about any location to maintain ideal growing conditions.
