Underfloor Heating in Australia
Electric underfloor heating is one of the most effective ways to heat bathrooms and larger tiled areas in Australian homes.
It provides even, consistent warmth underfoot, removes the need for wall heaters, and is typically installed during renovations or new builds where comfort and efficiency matter most.
At Hotwire, we specialise in electric underfloor heating systems designed specifically for Australian conditions, with over 20 years of experience supplying and supporting installations across the country.
Whether you’re planning a bathroom renovation, building a new home, or upgrading your heating, this page explains how underfloor heating works, what it costs, and which system is right for your project.

What Is Underfloor Heating?
Underfloor heating is a system installed beneath your floor that gently heats the surface from below.
Instead of blowing warm air into the room, it warms the floor itself, creating even heat across the space.
This makes it particularly effective in areas with tiled floors, where cold surfaces are most noticeable.
Types of Underfloor Heating
Under Tile Heating / In Screed Heating / Heating Mats
Electric systems use heating cables or mats installed beneath tiles.
They are best suited for:
- Bathrooms and ensuites
- Renovations
- Larger tiled areas
They heat quickly, are simple to install, and are the most common choice in Australian homes.

How Underfloor Heating Is Installed
Underfloor heating is installed before the tiling process.
- Heating cables or mats are laid over the prepared floor
- They can be covered with adhesive or levelling compound
- Tiles are installed over the system
- A licensed electrician connects the thermostat
In most projects, installation is quick and fits naturally into a standard renovation timeline.
Is Underfloor Heating Worth It?

It is most worthwhile in:
- Bathrooms
- Ensuites
- Tiled living areas
It may not be necessary in:
- rarely used rooms
- very large open spaces
- areas without tiled floors
For most bathroom renovations, it is one of the most noticeable comfort upgrades you can make.
