How much does underfloor heating cost?

Q: What affects the cost of underfloor heating systems in Australia?

System type: Electric is cheaper to install but dearer to run; hydronic is the reverse, and suits big areas. Area heated: Cost scales with m², though the thermostat and heat source costs are spread over bigger jobs. New build vs retrofit: Laying into a new slab or renovation is far cheaper than lifting finished floors. Floor covering: Tiles and stone conduct best; timber and carpet need specific systems and limit output. Heat source & controls: For hydronic, the heat pump or boiler and zone controls are a large share of the total.

Underfloor heating in Australia typically costs $70–$180 per m² installed, with an electric bathroom system around $900–$1,900 and hydronic whole-home systems $12,000 or more.

Tips before you post

— Electric systems need a licensed electrician and hydronic systems a licensed plumber — check the right trades are on the job.

— If you're renovating a bathroom anyway, adding electric heating mats is cheap; retrofitting later costs several times more.

— Ask for a running-cost estimate, not just the install price — the gap between electric and hydronic shows up on your power bill.
