What changes this appliance’s cost?
Electric showers draw high power for a short time. Flow setting, shower length and kilowatt rating matter more than the headline tariff alone.
At the illustration above, one use consumes 1.58 kWh. Five uses would cost about £2.14 and twenty uses about £8.55 at 27p/kWh. Your unit rate and measured consumption produce the most useful estimate.
How this example is calculated
Energy equals watts ÷ 1,000 × hours used. The headline uses 27p/kWh and excludes the daily standing charge.
