In-slab heating is an excellent way to warm up your Sydney home throughout the cooler winter months. This cost-efficient underfloor heating solution is ideal for both wet and dry areas, such as bathrooms, showers, laundry rooms, living rooms, kitchens, and patios.

At Calibre Connect, we specialize in the installation of in-slab heating in Sydney and its surrounding areas. Our in-slab heating solutions can solve your entire home heating needs, giving you a green heating solution that doesn’t drive up your energy costs. Besides, by installing it in your home or commercial building, you’d not only be saving money but also doing your bit for the environment!

The Advantages of In Floor Heating in Concrete Slabs

In-slab heating is a popular heating solution for warming coloured or polished concrete in new builds or renovations. Unlike similar electric underfloor heater mats and in-screed underfloor heating, this heating system provides gentle and efficient background warmth day and night.

Other notable advantages of having this green heating solution installed in your home include:

  • Evenly distributed whole-home heating: In-slab heating generates a thermal environment with evenly distributed heating, eliminating cold zones.
  • Healthier and cleaner indoor air: This heating solution does not attract bacteria, mould, and other allergens typically found in forced-air heating systems.
  • Perfect heating solution for large spaces: This electric floor heating has a slow warming time, typically 10 – 24 hours. It is the most affordable 24-hour heating solution for heating large areas because it uses off-peak power, saving monthly energy costs.
  • Best heating solution for new builds: In-slab heating is an excellent heating system for a new building because of its hassle-free installation. Though installing this heating system on an existing floor is possible, in-slab heating is best installed during the construction of the concrete slab. This installation process helps it function best.
  • Noiseless, space-saving operation: In-slab heating also offers quiet operation. And, since the entire system is embedded in the slab, it won’t take up any space in your home.

Custom In Slab Heating Installation Sydney Services

Effective in-slab heating installations guarantee even, all-around radiant heating and individual programmable control.

Calibre Connect offers dry in-slab heating installation services, meaning your builders must prepare the concrete slab for installation before our team’s arrival. The building construction team will also need to install the polystyrene insulation and reinforcing mesh and carefully mark the heating areas and the electrical controls’ exact position.

After these preparatory works, our experienced team of electricians will:

  • Install the thermostat and junction box along with any required relay panels.
  • Test the heating element’s ohm value and insulation resistance to ensure they are within acceptable operating standards.
  • Attach the heating cable and temperature sensor to the wire mesh per your custom installation plans.
  • Test the heating cable and temperature sensor before and during the concrete slab pour, entering the performance results at the end of the pour for warranty purposes.
  • Once the concrete is cured, our electricians will complete the thermostat’s wiring and other electrical control components.
  • The team will also check the heating element’s amp draw one final time to ensure it is working correctly before approving the system for operation.

In-slab underfloor heating is a green and cost-effective heating solution, ideal for large residential homes, new constructions, and commercial spaces. It is the perfect heating solution if you’re looking for affordable high-performance heating all year round.

In Slab Heating Installation – FAQs

Electric in-slab heating is more energy efficient than forced air systems like reverse cycle air conditioning because it heats people and objects directly, allowing lower air temperatures. Insulation beneath the slab further improves efficiency by up to 50%. However, it uses more electricity than hydronic systems and has slower heat response times.

It is recommended to wait 6 to 8 weeks after pouring the concrete slab before activating the heating system. This curing period ensures the concrete gains sufficient strength and prevents damage to the heating cables.

The heating cables or tubing are fixed to the top layer of the slab’s reinforcement mesh before the concrete pour. Insulation is installed beneath and around the slab edges to reduce heat loss. After pouring, the slab cures for several weeks before system activation. Zoning and programmable thermostats optimise energy use.

In-slab heating suits Sydney’s cooler months well, providing consistent radiant warmth. However, due to slower heat-up times, it’s less ideal for short heating periods or fluctuating weather. Proper insulation and zoning help maximise comfort and efficiency.

In-slab heating works best with tile, stone, laminate, or engineered timber floors. Carpet and solid hardwood act as insulators, reducing heat transfer efficiency and are generally not recommended over in-slab heating in Sydney homes.

While electric in-slab heating can use more electricity than some other systems, running it during off-peak hours and using programmable thermostats can reduce costs. It often uses less energy overall than forced air heating due to even heat distribution.

Installing cables before pouring ensures the slab itself becomes a thermal mass, storing and radiating heat evenly. This method reduces dust circulation, provides allergen-friendly warmth, and utilises off-peak electricity by storing heat for later use, lowering running costs.

In-slab heating typically runs overnight on off-peak electricity, which limits direct use of daytime solar power. However, integrating solar with battery storage or using hydronic systems with solar water heating can improve sustainability in Sydney homes.
