Warmup’s inslab heating cables are installed directly into the concrete foundation before the slab is poured. The system delivers consistent, energy-efficient warmth throughout the home with no visible heaters or ongoing maintenance. By integrating heating during the construction phrase, homeowners can enjoy seamless comfort built into the structure itself – an efficient solution designed to enhance everyday living.

Before and after install
Warmup’s inslab heating embeds electric heating cables directly within a concrete foundation pour, positioned after steel reinforcing mesh is laid. Cold tail links are routed to internal wall plates before pouring, leaving the element permanently concealed within a 20–60mm concrete slab; with no future maintenance obligations.
The slab’s substantial thermal mass absorbs and releases heat gradually, providing gentle, uniform background warmth across large floor areas, highly efficient for spaces in constant everyday use. Final activation via a Warmup intelligent control unit occurs once the finished flooring is complete.
Installing heating loops during the foundation stage costs significantly less than any subsurface retrofit and adds long-term property value. Warmup inslab systems are specified nationwide across single-residential builds and large multi-unit developments.
Warmup’s Australian technical team provides custom layout blueprinting and thermal load calculations tailored to your room dimensions and floor finish.
With over two decades of global underfloor engineering experience, Warmup provides structural comfort systems trusted for their technical simplicity, outstanding longevity, and direct trade support.
Complimentary structural blueprint layout review and load design calculations for every project.
Backed by an industry-supported 10-year product warranty (ts & cs apply).
Highly economical operation, averaging just $2.34 per day to heat an 8m²–9m² kitchen area for 6 hours (calculated at a standard tariff of $0.30/kWh).
Provides a perfectly versatile, ready concrete surface that accepts any floor covering, including polished finishes, carpets, vinyl, tiles, or engineered timber.
The foundation stage is your single, time-sensitive window to integrate low-cost structural floor heating into your build. Our expert local support team is here to guide owner-builders, architects, and electricians through every step—from wiring layout blueprints to final system commissioning.

Warmup Inslab Heating Cable: Ideal for installation in new homes and extensions, this system provides a low-cost solution for heating polished or colored concrete floors. Operating at 500–5000 watts with running costs comparable to or lower than heat pumps, this system delivers gentle warmth over extended periods to provide the perfect climate for frequently used rooms. Each Warmup Floor Heating Kit includes:
A: Warmup structural heating loops must be fitted after the reinforcing mesh grid has been completed, but immediately before the concrete is poured on site. The wires are bound to the steel tracks at carefully engineered intervals, with the wiring tails safely housed and directed to your future thermostat locations. The standard concrete truck pour then proceeds directly over the wires.
A: Operational running costs remain highly affordable due to the slab’s thermal properties; for example, warming an 8m²–9m² zone for 6 hours costs roughly $2.34 daily based on a $0.30/kWh tariff. Incorporating the cable during foundation preparation is the most cost-effective approach available, as it leverages an existing construction phase. Warmup offers complimentary project cost assessments—simply submit your building blueprints to our local office.
A: Integrating high-performance perimeter or under-slab insulation panels is highly recommended. Sub-slab insulation effectively isolates your heated mass from the earth below, reflecting the radiant warmth upward into your living spaces and significantly lowering overall warm-up times. Our technical team regularly incorporates insulation values into our custom load assessments.
A: Thermostat numbers correspond directly to your desired independent comfort zones. For example, setting up separate controllers for main family spaces, home theater rooms, or bedroom wings allows you to heat only the spaces in active use. Our specialists provide a complete zone and control diagram with every custom plan.
A: The main difference lies in the depth and timing of the layout within your floor build-up. Inslab wires are laid down early and embedded deep within the structural concrete base layer prior to the main pour. Inscreed wires are introduced much later in the building timeline, sitting within a separate 20–60mm sand and cement leveling screed poured on top of a cured concrete subfloor. Inslab is ideal for fresh, new concrete pours, while inscreed offers better flexibility for renovations or additions.
