Bottom Line
Verdict
Electric underfloor heating systems cost significantly less to install ($50–$110/sqm) than hydronic systems ($100–$200/sqm) but cost more to run. Electric systems are ideal for bathrooms, kitchens, and small areas where the system runs 1–3 hours per day. Hydronic systems are more expensive to install but use 50–75% less energy per hour to operate, making them the better choice for whole-house heating in cold climates where the system runs for extended periods. The break-even point is typically 5–8 years for a whole-house comparison, favouring hydronic for new builds in southern Australia, ACT, and New Zealand.
Choose electric mat or cable systems for bathrooms, en suites, and any tiled area under 20sqm — the lower install cost and short daily running hours make electric the better financial choice for these applications. Choose hydronic for whole-house heating in new builds and major renovations in cold climates (Melbourne, Canberra, Hobart, NZ South Island) — the higher install cost is recovered through lower running costs within 6–10 years. For whole-house heating in moderate climates (Sydney, Brisbane, Perth), electric systems may still be viable as the heating season is shorter. Always combine either system with quality insulation board and a programmable thermostat.
Comparison FAQ
Warmup Australia is cheaper on average in this comparison, but the right answer depends on your specific underfloor heating requirements including system type, floor area, floor covering, and whether supply-only or full installation is required.
System type (electric vs hydronic), floor area, floor covering compatibility, thermostat type, whether insulation board is included, and whether the quote covers full supply-and-install or supply-only usually affect total cost and value more than a blended average. Always confirm what is included in the quote and check product warranty terms.
