The ShowerStar Shower Sensor Timer & App has been proven to deliver average savings of 4 minutes per shower. That means big water and energy savings.

For a water efficiency program that can mean 36L per shower per day savings. Considering ~40% of users shower twice or more a day the savings are significant. 

For electric utilities a 4 minute reduction typically equals 1200 kWh a year of saving or even more, making the ShowerStar Shower Sensor Timer one of the most cost effective efficiency solutions available. 

A ShowerStar Shower Sensor Timer provides end-users with shower alerts during showers while giving utilities and sponsors access to a powerful dashboard with insights into anonymised  installation rates, water heating technology, and showering behaviour.

Showering data is automatically uploaded to the ShowerStar Portal whenever users connect the app and via autonomous background synching. This can can be viewed in custom utility dashboards powered by Microsoft BI and exported for further analysis.

Unlike many efficiency solutions, the ShowerStar Shower Sensor Timer & App delivers rich behavioural data and supports deployments ranging from a few devices to tens of millions.

Most efficiency measures save energy evenly across the day. Shorter showers do something more valuable: they cut load right when the grid is under the most strain.

TouchGrid data from more than 32,000 showers, recorded by logged shower timers, shows a clear pattern. 57% of all showers happen in just seven hours: the morning peak (6–9am) and the evening peak (5–9pm). The busiest single hour is 7am, with nearly 12% of the day's showers.

In solar-rich markets like Australia, that timing matters. Solar has barely started in the morning and has dropped away by evening.

Electric storage water heaters can do most of their heating in the middle of the day on solar, or overnight on off-peak tariffs. The problem is the reheat. A long shower can drain the tank, and the heater switches on to replace that hot water straight away, right in the peak. Some water heaters are programmed to delay reheating until an off-peak window, but many have no such control installed.

Shorter showers draw less hot water, so reheat cycles during the peak are shorter or don't happen at all. For electric utilities, that makes shower behaviour more than an efficiency measure. It's a demand response resource hiding in plain sight, and it doesn't require customers to change when they shower, only how long.
