Understanding Underfloor Heating Systems
Underfloor heating works by turning your floor into a large, low-temperature heat source. Instead of blasting hot air or relying on wall heaters, warmth radiates gently upwards, heating people and surfaces evenly.
For Perth homes, this makes perfect sense. Winters are cool rather than harsh, so you don’t need aggressive heating—just consistent warmth that removes cold spots and keeps floors comfortable underfoot. Radiant heating does exactly that, with less energy waste and better comfort.
Electric Underfloor Heating
Electric underfloor heating uses Australian-approved heating cables or ultra-thin mats installed directly beneath your finished floor. The system connects to a programmable thermostat, giving you precise temperature and timer control.
In Perth, electric underfloor heating is especially popular for renovations. The mats are only around 3mm thick, so they don’t significantly raise floor levels. They’re ideal under tiles, vinyl, and carpet—making them perfect for bathrooms, kitchens, and small living areas.
Underfloor Heating Installation Options in Perth
Choosing the right installation method is just as important as choosing the right system. Perth homes vary widely in construction style, and we design each installation to suit the structure—not the other way around.
Under Tile Heating Installation
Under tile heating places electric cables or mats directly beneath the tiles, within the adhesive layer. This delivers fast, responsive warmth exactly where you feel it most.
This is the go-to option for Perth bathroom renovations. Tiles are common in WA homes for their cooling properties in summer, and underfloor heating balances that perfectly in winter. Installation is quick—often completed in a single day—making it ideal for lived-in homes.
In-Slab Heating Systems
In-slab heating embeds pipes or cables within the concrete slab during construction. The slab acts as a thermal battery, slowly releasing warmth throughout the day.
Because slab-on-ground construction is so common in Perth, this method works beautifully for new builds. It offers unmatched consistency and efficiency, particularly when paired with off-peak electricity or heat pumps. While response times are slower, comfort levels are exceptional.
In-Screed Heating Installation
In-screed heating is installed on top of an existing slab and covered with a sand-cement screed. It responds faster than in-slab systems while still providing excellent heat retention.
This option suits Perth renovations and architectural homes with polished concrete or timber finishes. It does add floor height, so it’s best planned during major renovations or construction phases.
Perth 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.
