Winter electricity costs: plan heating and drying
Estimate seasonal electric heating and drying costs with active days, measured consumption and practical source-linked checks instead of promised savings.
Reviewed 8 November 2026. Worked figures are hypothetical unless explicitly identified as a sourced reference.
Budget for the weeks you actually use an appliance
A winter appliance used for twelve weeks should not automatically be projected across fifty-two. Write down the active period, time used and electricity rate. For heating with a thermostat, nameplate watts describe a power rating rather than a measured average across the whole day.
For a hypothetical 2,000 W electric heater drawing full power for two hours on each of 60 days: 2,000 / 1,000 x 2 x 60 = 240 kWh. At a fixed teaching rate of 25p/kWh, that is 60 pounds. Four hours per day doubles the scenario to 120 pounds. Real thermostat cycling can change consumption; these figures are not a prediction for your room.
Enter those assumptions in the appliance calculator. Do not use this electricity formula to price gas central heating or infer how much useful heat a heat pump delivers.
Match controls to the heating system
Review the timer and thermostat for your system and household schedule. Boiler and heat-pump operating strategies differ, so a blanket instruction to turn every system off while away can be misleading. Follow the manufacturer's guidance or ask your installer when changing controls. Keep radiators and thermostat sensors clear of obstructions.
Energy Saving Trust's heating-control guidance explains thermostats, timers and radiator valves. It also cautions against leaving rooms completely unheated for long periods because of condensation and mould risk. We do not assign a guaranteed cash saving to a thermostat adjustment.
Compare complete drying jobs
Use measured kWh for a representative load and programme, including any additional equipment used to achieve the same dry result. A heated airer, tumble dryer and dehumidifier are not interchangeable simply because their rated watts differ. Consider load size, drying time, ventilation and the room's conditions.
The measured-energy comparison handles different observation counts, then applies the same future schedule to each option. The household planner lets you limit seasonal rows to active weeks.
Review the result after a representative week
Record the programme, load, indoor conditions and measurement boundary. Revise assumptions when use changes. Do not reduce essential warmth or ventilation just to hit a calculator figure.
