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.

  • Expert support – from system design to installation, training, and troubleshooting.
  • High-quality components – rugged, waterproof cable with UL/CSA approvals.
