bath and shower

The typical standard for modern homes is 100 amp, 220 volt service (see this link), or 22 kilowatts. Installing a low-flow

**shower**head (1.5 gpm) saves 40% of that, 7955**watts**or about 800 bulbs, but it still**uses**1200 bulbs worth.

Similarly, it is asked, how many watts does a shower use per hour?

Appliance | Average power rating (Watts) | Cost to use per hour (pence)* |
---|---|---|

Electric shower | 7000–10500 | 105-156 |

Immersion heater | 3000 | 45 |

Kettle | 3000 | 45 |

Tumble Dryer | 2000-3000 | 30–45 |

**shower**, you

**use**more or less 15L/min of water. So, a

**shower**of 5 minutes will consume 75L of water, which amounts to 9 MJ, or 2.5 kWh. In a nutshell, when you take a hot

**shower**, you consume half a kWh per minute.

Similarly one may ask, how much electricity does a 10 minute shower use?

**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 min shower would use** 150litres of mains water, heated from around 8°C to 30°C.

Assuming that the rates of **electricity** and water in your area are near the national average, 12 cents per kilowatt-hour and $1.50/1k U.S. gallons, each **shower** will cost you 25 cents or 51 cents per day for the whole household, according to the **shower** cost calculator by Omni.
