Comfort
Warmth across the heated floor
A well-planned mat or cable layout helps spread warmth evenly across the heated area, making tile and stone more comfortable underfoot.

Warm floors, planned with SmartHeat
Warm bathroom tiles make winter mornings more comfortable. Mats or cables spread warmth across the heated floor, with no fan blowing air into the room. A programmable thermostat lets you schedule the heating for the times you use each room.
SmartHeat supplies electric heating mats, cables and thermostats for Sydney and NSW homes. Our team can help you check the heated area, floor finish and controls, and explain what to arrange with your installer and electrician.
Heating cables or mats beneath the finished floor warm its surface. The installation method depends on the flooring, available floor height and heat needed in the room.
Benefits of electric floor heating
Why choose electric underfloor heating?
Electric mats and cables heat the floor directly. You can plan separate heated rooms around your daily routine, without adding a boiler or water pipework.
Room control
Heat the rooms you use
Separate thermostats let you control individual heated zones. Keep a bathroom on its own schedule or set different temperatures for rooms used at different times.
Electric heat
No boiler or water pipes
Electric mats and cables use electricity to produce heat in the floor. They do not need a boiler or circulating water system, making them an option for adding warmth to an individual room.
Hidden heating
Quiet warmth, out of sight
The heating sits beneath the finished floor and operates without a fan blowing air into the room. With no wall-mounted radiators, more wall space stays available for furniture and storage.
Daily use
Set heating times to suit your day
A programmable thermostat lets you set morning, evening or weekly heating times. Choose a schedule that suits the room and allows for the time your floor takes to warm up.
Renovations
Add warmth when replacing a floor
Low-profile mat options can be considered when renewing a tiled floor. The mat, floor layers and electrical supply need to suit the project, so check these details before the new flooring is laid.

Which electric floor heating option suits your floor?
| Heating option | Where to consider it | What to check |
|---|---|---|
| Under-tile heating | Bathrooms, laundries, kitchens and other rooms with tile or stone floors. | Available floor height, tile adhesive, waterproofing, mat layout and floor sensor position. |
| In-screed electric heating | New floors or renovations that include a suitable screed or levelling layer. | The heating product, screed depth, insulation, finished floor level and warm-up time. |
| Under-timber heating | Rooms with a timber, engineered timber or laminate floor approved for the chosen heating system. | Written flooring approval, compatible underlay and the floor manufacturer's temperature limits. |
| Thermostats and controls | Every heated zone, with scheduling or Wi-Fi control where the chosen thermostat supports it. | Electrical load, sensor requirements, floor temperature limits and how the room will be used. |
Planning your project
Four steps to plan electric floor heating
Work through these decisions before the floor is laid. They help define what is needed and what to include in your enquiry.
01
Confirm the room and floor
Identify the floor finish, existing construction and available floor height. Decide whether you want warm floors or need the system to meet the room's heating demand.
02
Measure the area to be heated
Use a floor plan to mark the usable heated area and permanent fixtures. Choose mat or cable sizes for that layout, following the product's clearance requirements.
03
Plan the controls and power
Choose controls for each zone and agree on thermostat and floor sensor positions. Have your electrician check the supply and connection requirements.
04
Agree on installation and testing
Coordinate the heating with the flooring and waterproofing work. Follow the product's testing requirements and allow the floor materials to cure before first use.
Costs and energy use
What affects installation and running costs?
Installation cost depends on more than room size. The heated area, heating product, number of thermostats, floor preparation and electrical work all affect the price. When comparing quotes, check whether flooring, waterproofing and work by other trades are included.
Running costs depend on the system's installed power and how long it draws electricity, as well as insulation, the temperature setting and your electricity tariff. Controls can limit heating to the times and rooms you use. The floor construction and room heat loss still affect how much energy is needed. For a large area or long daily operating hours, compare the ongoing cost with other heating options.
See daily and monthly examples in our electric underfloor heating running costs guide, with the heated area, usage hours and electricity rate shown for each calculation.
- Share a floor plan showing the areas to heat and any permanent fixtures.
- Confirm the floor finish, insulation and any preparation needed.
- Ask which heating products, controls, electrical work and testing are included.
- Explain your preferred schedule so running cost estimates use realistic hours and settings.
Before the floor goes down
When should electric floor heating be planned?
Plan the heating before tiling, screeding or laying the final floor. The heating installer, electrician and flooring trades need an agreed layout, floor height and control positions. In wet areas, confirm how the heating fits with the waterproofing system before either is installed.
Installation and first-use timing depend on the selected products and the floor construction. Heating tests should follow the manufacturer's requirements at each relevant stage. Adhesives, screed and other floor materials need their specified curing time before the heating is switched on; do not use it to speed up drying.
Other heating options
Planning heating for more than one room?
If you need to heat a large area or want heating and cooling, consider these systems alongside electric floor heating.
FAQ
Common questions.
Which floor finishes work with electric underfloor heating?
Tile and stone are common choices. Some timber, engineered timber and laminate products can also be suitable, but the flooring manufacturer must approve the heating system, underlay and operating temperature. Check the specific floor product before ordering heating.
Can electric floor heating be added during a renovation?
It can be considered when floors are being replaced or rebuilt. The existing floor must be suitable, and the heating, adhesive or levelling layer and new finish will affect the finished height. Check door clearances, adjoining floors and wet-area requirements before choosing a system.
Can it heat a whole home?
Whether it can provide the room heating required depends on heat loss, available heated floor area and system output. For a whole home or large living area, compare the installation and operating costs with hydronic heating or reverse-cycle air conditioning before deciding.
Is electric underfloor heating expensive to run?
Running cost depends on the heated area, installed power, insulation, temperature setting, operating hours and electricity tariff. A thermostat switches heating as needed, so the rated output alone does not tell you the daily cost. A small bathroom used on a schedule has a different heating demand from a large area kept warm all day.
How quickly will the floor warm up?
Warm-up time varies with the floor construction, insulation, starting temperature and heating output. Allow for your floor's response when setting a thermostat schedule rather than relying on a fixed warm-up time.
Can I install electric underfloor heating myself?
Some products allow parts of the floor preparation or mat laying to be completed separately from the electrical work, subject to their installation instructions. Plan the wiring, connection and electrical testing with a licensed electrician before work starts. The heating layout must also suit the flooring and, in wet areas, the waterproofing system.
