Best Underfloor Heating Systems for Australia 2026
Underfloor heating is growing in popularity in Australian bathrooms and living areas, driven by the luxury feel of warm tiles in cold southern Australian winters and the improved efficiency of electric mat systems. Australian underfloor heating is primarily installed in two situations: bathroom renovations (electric mat systems under tiles are the most common application) and new home builds in cooler Australian climates where hydronic systems provide whole-home radiant heating. All underfloor heating systems in Australia require licensed electrician installation and must comply with AS3000 electrical safety standards.
Buying Guide: What to Look For
- 1Electric underfloor heating mats are suitable for Australian bathroom renovations — they're installed under tiles by a licensed electrician during a tiling project.
- 2Hydronic underfloor heating (hot water pipes) is more efficient for whole-Australian-home heating but requires major installation — typically done during new home construction or major renovation.
- 3In Australian climates, electric underfloor heating is primarily used for bathroom comfort (warm tiles) rather than primary room heating — supplement with reverse-cycle AC for room heating.
- 4The total installation cost in Australia includes the heating system + electrical work (licensed electrician) + tiling (if replacing floor covering) — budget all three together.
- 5For Australian bathroom underfloor heating, an electric mat at 150W/m² is the standard — a 3m² bathroom costs approximately 15c/hour to run at Australian electricity rates.
- 6Smart thermostats for Australian underfloor heating allow pre-warming before morning showers — scheduling with a Nuheat or Warmup thermostat is the standard Australian bathroom heating approach.

Editor's Note
Nuheat, Warmup, and Comfort Heat Australia are the dominant underfloor heating brands in the Australian market. Warmup has an Australian office and provides technical support to Australian contractors, making it the preferred brand for Australian bathroom renovation projects. Wunda Group's hydronic system is popular for Australian new builds in Melbourne and Canberra where hydronic heating is increasingly specified for energy efficiency in the cold-climate Australian Capital Territory and Victorian alpine regions.
Our Take
For most Australian bathroom renovations, a Warmup or Nuheat electric mat system (approximately $200–$400 for the mat, plus $300–$500 electrician installation) is the most practical underfloor heating addition. For Australian new builds in cold climates (VIC high country, ACT, TAS), hydronic underfloor heating is worth specifying as the primary heating system — it's more efficient at Australian electricity prices when connected to a heat pump water heater.

Australian-made outdoor infrared heater — a related Australian heating product popular for covered patios where underfloor heating isn't practical.
Wunda Slimline Hydronic Underfloor System

Frequently Asked Questions
Is underfloor heating worth it in Australia?
For Australian bathrooms, yes — warm tiles on a cold Melbourne or Hobart winter morning are a significant lifestyle improvement. The running cost of a 3m² bathroom electric mat (about 15c/hour) is manageable for 1–2 hours of morning use. For whole-home underfloor heating in Australia, it's worth it in new builds in cold climates (VIC, ACT, TAS) but difficult to retrofit into existing Australian homes with concrete slabs.
Do I need a licensed electrician for underfloor heating in Australia?
Yes — all electrical connection work for Australian underfloor heating must be performed by a licensed electrician. This includes the thermostat connection, circuit installation, and any wiring from the mat to the switchboard. Installing yourself in Australia voids product warranty, may breach building regulations, and creates electrical safety risk. Budget for licensed electrician costs ($300–$600) when planning an Australian underfloor heating project.
What is the running cost of underfloor heating in Australian bathrooms?
An electric underfloor heating mat at 150W/m² for a 3m² bathroom costs approximately 13–16 cents per hour at Australian electricity rates (28–35c/kWh). Running for 1.5 hours each morning costs $70–$90 per year. A 5m² master ensuite costs proportionally more — approximately $115–$140/year for 1.5 hours daily heating. Smart thermostat scheduling ensures the floor is warm exactly when needed without wasted heating time.
Can underfloor heating go under Australian timber floors?
Electric underfloor heating can be installed under engineered timber and laminate floors in Australian homes if specified within the manufacturer's temperature limits — most Australian timber floor manufacturers allow underfloor heating below 27°C surface temperature. Solid Australian hardwood flooring (Blackbutt, Spotted Gum) is less suitable as it can dry out and gap. Always check the Australian timber floor manufacturer's warranty — many void warranty if underfloor heating is installed without prior written approval.
Which underfloor heating brand is best in Australia?
Warmup and Nuheat are the most recommended brands in Australia, both with Australian distributor support. Warmup has an Australian office and provides contractor training across the country. Nuheat is popular in Australian bathroom renovation channels for its slim low-profile mat construction. Comfort Heat Australia is a local brand with direct Australian manufacturing support. All three are compatible with Australian 230V electrical systems and provide Australian warranty support.
