What Affects the Price of Underfloor Heating?

System type: electric vs hydronic

Electric systems ($50–$150/sqm installed) cost significantly less to install than hydronic (wet) systems ($100–$200/sqm) but are more expensive to run. Hydronic systems require a boiler or heat pump, manifolds, pipework, and screed — much more complex and costly to install but cheaper per hour to operate. For bathrooms and small areas, electric is usually the better choice. For whole-house heating in cold climates, hydronic wins on running costs.

Floor type and condition

Under-tile installation is the most straightforward — electric mats sit in the tile adhesive layer with minimal floor height increase. Timber and engineered wood floors require low-temperature systems and careful specification to avoid warping. Existing floors that need lifting and relaying add significant labour cost. New-build installations are cheaper than retrofits as the floor is not yet laid.

Room size and system complexity

Small bathrooms (4–8sqm) cost $600–$1,800 fully installed including thermostat. A whole-house electric system for a 200sqm home can cost $10,000–$18,000 as the electrician must install mats in multiple areas, run new circuits, upgrade the switchboard, and commission multiple thermostats. Larger jobs offer better per-sqm rates.

Insulation and substrate

Without adequate insulation board beneath the heating system, a significant proportion of heat is lost downward into the slab or subfloor. Insulation board ($15–$35/sqm) adds to upfront cost but reduces running costs by 20–40% over the system's life. On suspended timber floors, insulating the subfloor before installing UFH is essential.

Thermostat and control technology

A basic thermostat with manual programming costs $150–$300 installed. A smart WiFi thermostat with app and voice control costs $250–$500 installed. Smart thermostats can reduce running costs by 20–30% through scheduling and occupancy sensing. Multi-zone systems with separate thermostats for each room offer more precise control but add cost.

How to Get Underfloor Heating Installed

Step-by-step guide from system selection to running your new underfloor heating

1

Choose the system type and floor area

Measure the floor area to be heated. Decide between electric (best for bathrooms and small areas) and hydronic (best for whole-house heating in cold climates). Consider the floor covering — tile is the most compatible, followed by engineered timber. Confirm your floor substrate will accept the system and allow for any height increase.

2

Get 2–3 quotes from licensed tradespeople

For electric systems, engage a licensed electrician experienced in underfloor heating. For hydronic systems, engage a licensed plumber or specialist UFH installer. Provide the floor area, floor type, system preference, and whether the floor needs lifting. Ask for a quote that separates material and labour, and confirms what's included.

3

Installation day

For electric mat systems: the floor may need lifting, the insulation board is laid, the heating mat or cable is installed and connected to the thermostat and power circuit, and the floor covering is relaid. For hydronic systems: the pipework is installed, manifold connected, screed poured, and the system connected to the boiler or heat pump. Commissioning and testing completes the installation.

4

Post-installation setup and running costs

Programme the thermostat with your preferred schedule — most systems should be set to pre-heat the floor 30–60 minutes before the room is used. Electric systems typically cost $0.03–$0.08/hour to run per sqm depending on electricity tariff. Hydronic systems cost significantly less per hour but require more complex commissioning. Keep the installation certificate and warranty documentation.

How to Save Money on Underfloor Heating

Choose electric for small areas

For bathrooms under 15sqm, electric mat systems are the most cost-effective choice — installed cost of $600–$1,800 per bathroom vs $5,000+ for a hydronic system in the same room. The higher running cost of electric is offset by the short running hours in a bathroom (typically 1–3 hours/day).

Install insulation board from day one

Insulation board ($15–$35/sqm) is the single best investment to reduce running costs. Without it, 30–50% of heat is lost downward into the slab. Including insulation board at installation costs less than adding it later and pays for itself in reduced electricity bills within 1–3 years.

Use a smart programmable thermostat

A smart thermostat ($250–$500 installed) allows scheduling, geofencing, and remote control via smartphone. Studies show smart thermostats reduce UFH running costs by 20–30% compared to manual control or always-on operation. The payback period is typically 1–2 years.

Combine with solar panels

If you have rooftop solar, scheduling your electric underfloor heating to run during peak solar generation hours (10am–2pm) can dramatically reduce running costs. In Australia's sunny climates, solar-powered electric UFH in bathrooms and kitchens can approach zero marginal running cost during the day.

Underfloor heating in Australia costs $50–$90/sqm for an electric mat system, $60–$110/sqm for an electric cable system, and $100–$200/sqm for a hydronic (wet) system. A complete bathroom installation (electric mat, thermostat, and fitting) typically costs $600–$1,800. A whole-house hydronic system costs $15,000–$35,000 fully installed. Prices include GST and are for a licensed installer.

Electric underfloor heating uses electric resistance cables or mats installed under the floor. It is cheaper to install ($50–$110/sqm) but costs more to run. It suits bathrooms, kitchens, and small areas. Hydronic underfloor heating circulates warm water through pipes in or under the floor, heated by a boiler or heat pump. It costs more to install ($100–$200/sqm) but is far cheaper to run, making it ideal for whole-house heating in cold climates.

Yes, but it requires careful system specification. Timber and engineered wood floors require a low-temperature system (typically hydronic or a low-wattage electric cable) to prevent the wood from drying out and warping. The timber must be specified for use with underfloor heating and must have a maximum moisture content of 10%. Electric foil mats under floating engineered timber or LVP floors are a common retrofit solution.

Electric mat and cable systems typically warm a tiled floor to a comfortable temperature in 20–45 minutes. Hydronic systems in a concrete slab take longer — typically 1–3 hours to reach operating temperature, but the thermal mass of the slab then radiates heat for hours after the system switches off. Programme your thermostat to start heating 30–60 minutes before you need the room.

Yes. Electric underfloor heating involves electrical work and must be installed by a licensed electrician in all Australian states and territories. Hydronic underfloor heating involves plumbing and must be installed by a licensed plumber. DIY installation of either type is illegal in Australia and will void insurance. Always request a compliance certificate on completion.
