Question: electric shower how much electricity does it use?
Answer: In terms of costs, there would be a difference between fuel types. Electricity is generally charged at about 12p per KWh, so for a 10-minute shower using a 7.5kw shower would cost 15p. A power shower could use around 15litres/min, so a 10-minute shower would use 150litres of mains water, heated from around 8°C to 30°C.
