Running Cost Estimator
Floor Heating Cost Calculator
Select your heating system, floor area and electricity tariff to see indicative daily, weekly and annual running costs.
01 · System & Usage—
Electric screed heating · 175 W/m² draw · 60% duty cycle after 1 hr warm-up.
Recommended heating hours. Warm-up period runs at full power to reach temperature, then duty cycle applies.
02 · Energy Tariffsc/unit
Edit values to match your retailer's current rates.
Converted to c/kWh at ×3.6 (1 kWh = 3.6 MJ), assumes 100% boiler efficiency.

Key Assumptions
Warm-up period (1 hr for thin electric systems, 2 hr for slab and hydronic systems due to higher thermal mass) runs at 100% full load to reach target temperature, then the duty cycle applies for the remaining hours. Duty cycles vary with insulation, climate and target temperature. Gas boiler conversion uses 1 kWh = 3.6 MJ at 100% efficiency; real-world efficiency reduces this. Tariffs are user-entered and should reflect your retailer's current rates. Figures are indicative only.
