In-Slab Radiant Floor Heating: A Smart Choice for New Homes

When building a new home or pouring a fresh concrete slab, you have a golden opportunity to incorporate luxurious and efficient heating right into your foundation: Warmzone’s In-Slab™ Radiant Floor Heating.

A single-story home under construction with exposed OSB wall sheathing and framed window openings. 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.

Warmzone Slab Heating Cable

Warmzone’s In-Slab Floor Heating Cable is Tops in Efficiency

If you’re looking for a way to efficiently, effectively heat concrete floors, In-slab radiant heat cable is much less expensive than hydronic radiant heat and much more effective. Designed for installation in new concrete slab applications, this cable can heat a variety of surfaces quickly, from carpet to tile, hardwood and more.

By its very nature, in-slab heat systems require less upfront investment, are much easier to install and feature much quicker response times. Consider hydronic systems–they’ve been around the longest, and are definitely a reliable source of heat. However, these systems rely on a boiler and a network of pex tubing to heat concrete surfaces, making their installation and configuration much more labor and cash intensive. A boiler is also required to heat the water first, before pumping it through a series of pex tubes embedded in the concrete, resulting in a significant pause before the water is warm enough to generate any heat.

Conversely, In-slab radiant heat cables are controlled by a technologically advanced, easy-to-used thermostat with a built in GFCI and an in-floor sensor. And radiant heat cables do not share the same rigidity in design and installation as hydronic Pex tubing does. Extremely bendable, electric radiant heating cable can be bent to fit into tight spots and can be installed to fit the most challenging spaces. Once installed, a turn (or pre-programming) of the thermostat dial allows the system to generate heat within just a few minutes.

Durable, rugged and waterproof, In-slab heating cable is designed to work under a variety of surfaces, wet or dry. The cable produces 10-15 watts per square foot of concrete surface, making it equally perfect for small, custom, residential applications and large commercial jobs. Quick activation times and heat storage within the concrete slab also end up saving you money in the long run. The In-Slab heating system is one of the most efficient floor heating systems available.

If you’re a do-it-yourselfer, choosing electric radiant heat over a hydronic system can also save you some hand-wringing and a few bucks to boot. Laying out of series of Pex tubing for a hydronic system requires some serious planning and coordination as the pipes are assembled, connected and sealed. In addition to In-Slab heat cable that is provided on spools, floor heating cable is also available in easy-to-roll-out mats that can be installed directly under the flooring. Visit Warmzone’s ComfortTile floor heating web pages to learn more about this electric radiant heat cable that can be purchased right off of the spool or in pre-configured mats. It’s another industry leading floor heating solution that can be used to heat a variety of floor surfaces.
