The structure sits on a freshly poured concrete slab, ideal for embedding in-slab radiant heating cables before vertical framing begins. The surrounding area shows construction materials, red soil, and a partially cloudy sky, highlighting the early stages of a new residential build.

What Is In‑Slab Radiant Heating?

This system embeds rugged electric heating cables directly into your concrete slab—typically 1–2 inches below the surface—turning the entire slab into a radiant heater. The cables generate warmth that the concrete absorbs and distributes evenly throughout the space.

Key Benefits

  • Ultra‑Efficient & Quick Response: Heating cables embedded in concrete warm rapidly and evenly. Thanks to thermal mass, once warmed, they hold heat reliably.
  • Low Upfront & Installation Ease: In-slab electric systems require no heavy boilers or tubing networks—just durable heat cable laid on your rebar, ready for a concrete pour.
  • Durability & Reliability: Built to last with metallic shielding and waterproof sheaths, the cables are UL/CSA compliant, maintenance-free, and backed by a non-prorated 10‑year warranty.
  • Energy Savings & Smart Control: Programmable thermostats with in-floor sensors allow you to heat only when needed. Coupled with electric thermal storage (ETS), you can run the system during off-peak hours for added savings.
  • Cleaner & Healthier Homes: Radiant heat operates silently and quietly, without allergens or drafts—perfect for allergy-prone families, as there are no air blowers to circulate dust.

Why Choose In‑Slab Over Other Systems?

Electric in-slab systems offer a sweet spot between cost, simplicity, and comfort—ideal for new construction. They install quickly during the concrete pour and integrate seamlessly with a variety of floor coverings. Plus, they deliver consistent, energy-efficient warmth with minimal maintenance.

Applications & Compatibility

Whether you install hardwood, tile, carpet, or polished concrete, the slab evenly transfers heat across a range of floor finishes. It’s especially effective in cold-weather spaces, such as basements, bathrooms, or open-concept living areas.

Learning About Radiant Heat

I’m a bit of a nerd. Or maybe I’m a geek. Regardless, I like techy stuff, and I enjoy learning how things work. While my wife is watching reruns of Gilligan’s Island, I’m in the other room, watching “How it’s Made” on the Science Channel. On the weekends, I get a little wild and watch documentaries on the Smithsonian and History channels. I like to mix it up.

The point is, I like to understand what makes things tick. That way, I tend to appreciate them a little more. I’m not the least bit interested in keeping up with the Kardashians, or watching adults behave like ill-mannered adolescents on staged “reality” shows. I’d much rather know important things like, how Silly Putty is made, or how they put those little model ships into glass bottles. You know, life-skills type of stuff.

Being of curious mind, I’ve also found myself intrigued with radiant heat technology. Radiant heat is becoming more and more popular nowadays, for both interior (heated floors) and exterior (snow melting) applications. Apparently, the Europeans got a jump on us when it came to installing radiant heat in their homes. (Yes, I’m setting my grandiose American ego aside and conceding that the Europeans were way ahead of us in the home heating race.) I’m not sure why North America was slower to adopt radiant heat, but we’re certainly making up for lost time now. Radiant heated floors and heated driveways are rapidly becoming commonplace in today’s new homes. In fact, seeing so many heated driveways, and experiencing homes with heated floors are what piqued my interest in radiant heat.

But how do these systems work? Why are Americans making the shift to radiant heat? And is it true that radiant heat is the most efficient heating technology available today? These are just a few questions that launched me on my quest.  

Early in my investigation, I was surprised to discover how many different types of heating elements are available, and how they work with different floor types. Thin heat resistance cable was the only heating element that I knew about, but apparently, there are many, very different, heating elements, each with their own specific features and benefits.

Floor heating systems that use thin heating cable are probably the most popular. Most heat cable is available off the spool or pre-spaced in mats. I gotta say, these heating mats are slick. Ya just roll ‘em out over the area to be heated, and the adhesive on the back of the mat sticks to the subfloor. Needless to say, this makes installation quick and easy. System that use heat cable, s like ComfortTile, are ideal for heating stone, marble, and tile floors. And because the heat cable is thin, there is very little floor buildup. ComfortTile seems to be the cable of choice for many homeowners and installers. (It doesn’t hurt that the cable also has a 25-year warranty.)

There are also thin heating panels that can be installed under just about any surface, including hardwood, vinyl tile, linoleum, and more. One remarkable – and very popular – system is FilmHeat. FilmHeat utilizes ultra thin panels that are barely thicker than a sheet of paper. (The element is just 0.016-inch thick.) The heating element is used with an underlayment, and doesn’t even require the use of thinset or mortar. This makes for a clean and easy installation! A special version of this system, called RetroHeat, can also be used to install between floor joists. This allows homeowners to heat their existing floors! I love the idea of heating my floors without having to do any major renovations.

Special heat cable is also available for installation in concrete slabs. Because of its intended applications, the In-Slab heat cable is thicker, and more robust than other floor heating cables. It’s ideal for heating rooms in the basement.

Another unique floor heating system is the low-voltage FloorHeat STEP system. The system features thin, flexible polymer heating panels that have proven to be especially well-suited for heating hardwood floors.  

All these systems are incredibly efficient. In fact, 99 percent of the energy used by these systems translates directly into heat. There’s virtually no heat loss. In today’s environmentally conscious mindset, radiant heat is a winner. It’s clean. It runs on renewable energy, and it provides far more comfort than traditional furnace-blower heating systems. I also like the flexibility that radiant heat offers. I can heat specific rooms and areas as I see fit. Because each zone (or room) is controlled by its own thermostat, I have precise control over my home heat. The systems can also be programmed to accommodate my family’s schedule. (Hydronic floor heating systems are also available. A closed loop of PEX tubing is installed under the floor, and then specially treated water is heated and pumped through the tubing to warm the floor.)

When it comes to exterior applications such as heating driveways, steps, and walkways, etc., the most common heating element is durable heat cable. The ClearZone system is a favorite among professional builders, and can be customized to accommodate just about any layout and application. The systems utilize an advanced snow sensor activation device that detects precipitation and temperature so that the system is activated just as the first snowflake falls. The sensor signals a small controller that is typically installed on a wall in the garage, and then power is sent to the embedded heat cable. The driveway quickly warms so that snow is prevented from accumulating. After the snowstorm, the system remains on for a short time to dry the surface. This is a great safety feature that eliminates ice from forming on the driveway.

It’s no wonder that radiant heat has become the new standard for home heating and snow melting applications.

Or, you could just catch an old episode of Gilligan’s Island. Fortunately for the crew of the S.S. Minnow, they didn’t need to heat their bungalows. But if they did, I bet the Professor would have found a way to incorporate radiant heat.

About Radiant Heat

Radiant heat is an amenity that can increase comfort and convenience in any home. With its ever growing popularity, many people are looking to see if radiant heat is a good fit for their home or business. Like any home improvement, there are pros and cons to consider when considering radiant heat.

To understand the pros and cons of radiant heat, it’s important to understand what radiant heat is, and how it works. Radiant heat comes in two forms: hydronic and electric. Hydronic radiant heat sends specially treated hot water through durable Pex tubing underneath the floor. Electric radiant heating systems use a network of conductive material placed underneath the floor to heat the room.

Electric radiant heat is becoming an increasingly popular choice. These systems are much easier to install and are ideal for heating specific areas or rooms. Electric floor heating systems generally use a heating cable (off the spool or pre-spaced cable in mats) or thin heating panels. The heating element is connected to a thermostat, and each room or zone can be controlled separately, giving you precise, efficient control over your heating system.

Radiant heat differs from conventional heating because it heats objects (like the floor) as opposed to air. The room warms from the floor up. The floor heat spreads to objects in the room, such as furniture and fixtures, which ultimately provides comforting warmth for the room. This dispersal method allows for consistent heat throughout any room.

A Few Advantages of Radiant Heat

Energy Efficient

Radiant heat is an extremely energy-efficient choice, especially when compared to traditional HVAC systems. All the heating in the home radiates upward from the floor, keeping more of the heat where you need it most. With a radiant heating system, you can lower the temperature by a few degrees and still enjoy a nice warm room, reducing the utility budget. Unlike forced-air systems, there is no hot air being wasted by blowing from vents and rising to the ceiling. Radiant heat systems are also room specific, and there is virtually no wasted energy. Heat transfers efficiently from the floor through to other objects. Each room can be heated according to your precise needs, allowing for even greater savings on monthly utility bills.

Consistent, Even Heating

An HVAC system blows warm air throughout the home, but this warm air doesn’t heat the home uniformly, leaving cold and hot spots. With radiant heat, the heat rises evenly from the flooring, warming the entire room. This uniform heat provides luxurious warmth throughout the room, eliminating cold spots.

Hypoallergenic

Radiant heat is also hypoallergenic. HVAC systems not only blow air, but also blow dust, allergens, and other particles that may be trapped in the ducts. With radiant heat, this is not a concern. This advantage is great for the small children, the elderly, or those who struggle with allergies or other health issues.

Easy Installation

Radiant heat is a great choice for new construction homes or homes undergoing a remodel. Simply purchase a radiant heat system, and install before laying flooring. A professional at Warmzone can help identify the best system and layout for any home’s needs. Electric floor heating systems are also very easy to customize, so they can be installed to heat small rooms and areas if you’re looking to supplement your existing heating system.

RetroHeat installed to heat existing tile floor

If considering radiant heat for an existing home, options like RetroHeat from Warmzone are available to keep installation quick and simple. Many homeowners don’t realize that radiant heat can be installed under existing floors – without the need for major remodeling. If you have asses to the floor joists (through a basement or crawl space), you can install the RetroHeat floor heating system. The thin panels are stapled up between the joists and then batt insulation is stapled up over the heating elements to direct all of the heat upward to warm the floor. This is an affordable option for heating existing floors without the need of replacing or tearing out any flooring. RetroHeat can be installed under almost any existing flooring by accessing the floor joists.

Quiet

Radiant heat systems are not only energy efficient, but also almost completely silent when operating. HVAC systems create noise when turning on and off to regulate temperature, but radiant heat makes no noise at all, making it a great choice for any home.

If you’re wondering what the catch is with radiant heat, here are a few more aspects to consider when before installing a radiant heat system.

Other Considerations

Depending on the system you install, one possible disadvantage is that it may result in some floor build up (raising the floor slightly). Several electric systems cause no floor buildup, but this is not true of all systems. Most radiant heat systems are extremely low profile, so the buildup is virtually unnoticeable. However, it is important for your contractor to know the specifics of the floor heating system you are considering. There are many floor heating options available from Warmzone that cause little or no floor build up, so talk with a Warmzone floor heating expert to learn what options are best for you.

Perhaps the biggest question for home or business owners is how much does radiant heat cost? While the initial cost of radiant heat can seem high, it is a great investment that can save money over the life of any home by reducing utility costs. (Learn more about How Much a Radiant Heated Driveway Costs.)

Radiant heat is also a great way to increase the value of a home. If cost is a concern, radiant heat can also be custom installed to only heat certain rooms that could use some additional heat. A Warmzone customer service professional can help you find the right system to best meet the needs of your household, as well as the budget.

Radiant Heat – The Heating System of Choice for New Construction Projects

With the emphasis on renewable energy and enhancing the efficiency of our homes nowadays, it’s no wonder that radiant heat is fast becoming the heating system of choice for new home construction. Radiant heated floors boast virtually no heat loss as over 99% of the energy devoted effectively translates into heating the home. Unlike traditional forced-air heating systems where hot air rises quickly and cools in the room (and escapes from closed vents), radiant floor heating systems feature no heat loss and precise control, as each room (or zone) is controlled by its own thermostat.

Heated bathroom floor

In addition to its remarkable energy efficiency, radiant floor heat also provides luxurious warmth. Installing a radiant heat system in your home not only can enhances cost savings and comfort, but can also significantly boost the value of your home.

Radiant floor heating systems consist of three main components: a heating element, a control center and an activation device (thermostat, timer, etc.). Warmzone offers a variety of the industry’s most advanced thermostats with its floor heating systems. The thermostats include simple on/off controllers and 7-day programmable thermostats that can be controlled by an external sensor (embedded in the floor), a built-in sensor, or a combination of the two. By installing heated floors, homeowners can turn a small investment into considerable cost-savings that also increases the value of your home.

The Types of Heating Elements

To accommodate the many different floor types and applications, Warmzone offers one of the largest selections of floor heating systems. The various systems utilize different types of heating elements, each with their own strong points and advantages.

ComfortTile floor heating mat

The most common and popular heating element is thin ComfortTile heat resistance cable. The cable diameter is only about 1/8-inch and has a bending radius of about 1 inch. It is twin-conductor cable with a single point connection to facilitate easy installation. And speaking of easy installation, ComfortTile mats feature heat cable that is pre-spaced on a flexible mesh backing for simple “roll out” installation. With a 25-year limited warranty, and UL listed in the U.S. and Canada, ComfortTile heat cable is one of the most trusted and commonly used floor heating solutions today.

Prodeso floor heating membrane

Thin heat cable can also be used with other components, such as the Prodeso® floor heating membrane. The uncoupling, waterproofing membranes come in rolls that are laid out over the subfloor and then the heat cable is installed in the channels of the membrane. This ensures precisely accurate spacing and speeds up the installation process. The floor surface is then installed directly over the membrane and heat cable. The system can be used to heat a wide variety of floor types.

A thicker, highly rugged heat cable is also available for installation in concrete slabs. In-Slab heat cable provides an efficient and highly effective means for heating floors that are installed over concrete slabs. The heat cable is secured to the remesh (with zip ties) and the concrete is poured. In-Slab floor heating systems are ideal for heating basement level floors. The twin conductor, single point connection heat cable features a 10-year manufacturer warranty.

Another heating element features thin FilmHeat (only 0.016-inch thick) that can be cut to length on site and either placed on the subfloor to heat newly constructed floors or stapled up between floor joists to heat existing floors. For new floors, this heating element is installed by floating it on top of an underlayment and floating the floor covering on top of the film. No alarms, special tools, or self leveling compounds are needed. This versatile system is very energy efficient, and because it is so thin there is no floor buildup. The system can be used to heat a range of floor types, including laminate, floating tile, engineered wood, and even bamboo.

Low-voltage radiant heating element.

Thin polymer FloorHeat panels can also be installed to heat a variety of floor types, including hardwood. This low-voltage system is one of the most unique and innovative radiant heat systems, and features self-regulating heating elements. Purchased in rolls, the thin, 12-inch wide heating element can be cut to size and field wired onsite for easy installation.

Another ultra thin FoilHeat electric radiant floor heating system features thin fluoropolymer insulated heating cables that are sandwiched between two layers of specially reinforced aluminum foil. Featuring superior design and quality construction, FoilHeat is another viable option for heating laminate floors.

The watertight heating element is connected to a power-supply cable that exits the laminate mat from one corner. The power lead is a flat, thin two-core flexible cord, consisting of two insulated conductors with a metal sheath and an outer sheath. The uniform spacing of the heating cable, backed by the conductive aluminum foil, ensures that there are no problems of “hot-spots” or localized heating. FoilHeat mats can be cut and shaped onsite.

In addition to the vast selection of electric radiant floor heating systems, Warmzone also offers industry leading hydronic floor heating solutions. For more information about our radiant heat systems, call 888.488.9276 today.
