Understanding Underfloor Heating Systems
Underfloor heating provides gentle, radiant heat through cables or pipes installed beneath your flooring. Instead of heating the air like traditional systems, radiant heat warms the room from the ground up—right where you feel it most.
This makes underfloor heating particularly well suited to Adelaide’s mild winters, where consistent, low-level warmth delivers comfort without excessive energy use. Unlike ducted or radiator heating, underfloor heating avoids hot and cold spots, drafts, and wasted heat near ceilings.
Electric Underfloor Heating Systems
Electric underfloor heating uses heating cables or mats installed beneath tiles or other floor finishes. These systems connect directly to your home’s electrical supply and are controlled by programmable thermostats for precise temperature control.
For many Adelaide homeowners, electric underfloor heating is the perfect choice for:
- Bathrooms
- Kitchens
- Laundries
- Small living spaces
Installation is fast and minimally invasive, making electric systems especially popular for renovations. If you’re upgrading a single room and want reliable warmth underfoot, electric underfloor heating offers excellent value.
Radiant Heat and Its Benefits
Radiant heat is what makes underfloor heating so effective. Rather than warming air, radiant heat warms people and objects directly, creating a natural and evenly distributed warmth throughout the room.
Key benefits include:
- Consistent heat with no cold spots
- Improved comfort at floor level
- Reduced energy loss
- Quieter operation with no moving air
With proper insulation beneath the heating system, electric underfloor heating can maintain comfortable temperatures while keeping running costs under control—an important consideration for Adelaide households.
Types of Underfloor Heating for Adelaide Homes
At Livella Underfloor Heating, we install underfloor heating systems using three primary methods, depending on your home’s construction and renovation plans.
In-Slab Heating Systems
In-slab underfloor heating is installed directly into the concrete slab during construction. This option is only suitable for new builds or major extensions.
For new Adelaide homes, in-slab heating delivers exceptional efficiency. The concrete slab acts as thermal mass, slowly releasing heat and maintaining steady indoor temperatures with minimal energy input.
In-Screed Heating Solutions
In-screed systems are installed within a screed layer applied over an existing slab. This method is ideal for renovations where floor finishes are being replaced.
We often recommend in-screed underfloor heating for:
- Bathroom renovations
- Kitchen upgrades
- Living areas with tile or stone flooring
The screed provides a stable base while accommodating heating components without structural changes.
Under-Tile Heating Systems
Under-tile heating systems use ultra-thin electric mats installed directly beneath tiles or stone. With a thickness of just a few millimetres, they’re ideal for existing Adelaide homes where floor height is limited.
This solution is especially popular in older or heritage properties, where maintaining original floor levels and door clearances is essential.
In Summary:
- In-slab = best for new builds
- In-screed = ideal for renovations
- Under-tile = perfect for retrofits
Floor Coverings and Heating Systems
Floor coverings play a major role in underfloor heating performance. Tiles and stone conduct heat exceptionally well, making them the most efficient choice for underfloor heating systems.
Carpet and timber floors can also be used, provided they meet insulation and thermal resistance requirements. Engineered timber is generally preferred over solid hardwood, and low-tog carpets help ensure efficient heat transfer.
Good subfloor insulation is critical in all installations, helping direct heat upward into your living space rather than losing it into the slab or ground.
Adelaide Electric Underfloor Heating System Cost Guide
| System Type | Installation Cost | Typical Running Cost | Maintenance Cost | Lifespan |
|---|---|---|---|---|
| Electric Underfloor Heating – In-slab | $900 – $3,000 per room | ~ 6c per m², per hour | $0 | 25+ years |
| Electric Underfloor Heating – On-slab (Screed/Mats) | $900 – $1,500 per room | ~ 3c per m², per hour | $0 | 25+ years |
| Hydronic In-slab Heating | $12,000 – $25,000+ whole home | Variable (depends on gas/electric heat source) | ~$300–$800 per year | 20–30 years |
| Ducted Heating (Reverse Cycle or Gas) | $8,000 – $20,000+ whole home | Variable (higher for whole-home use) | ~$150–$400 per year | 10–15 years |
Summary:
- In-slab electric suits new builds where thermal mass is desired, with predictable running costs and no maintenance.
- On-slab electric is ideal for renovations, with faster heat-up times and lower running costs per m².
- Hydronic heating can perform well in large, highly insulated homes but involves high upfront costs, complex plant equipment, and ongoing servicing.
- Ducted heating has lower install cost than hydronic for whole-home coverage but requires regular maintenance and typically has a shorter lifespan.
Disclaimer:
Actual installation and running costs will vary depending on room size, insulation levels, electricity or gas rates, climate, system design, and usage patterns.
