Why this matters
Electric underfloor systems run at predictable watt densities, so once you know your room area and insulation level you can size the correct kW load and budget the monthly bill before a single cable is laid. The warm-up energy of a 60 mm screed is often 10–20% of the first month's consumption — a detail installers forget but homeowners pay for. Use this estimate as a sanity check when comparing underfloor heating quotes on TUNA.
