Compare your options
| Your situation | What to consider |
|---|---|
| Use less shower water | Compare hand-shower or overhead-shower flow in l/min at the stated reference pressure. |
| Avoid unnecessary hot-water demand | A CoolStart tap supplies cold water with the handle centred. Check this feature on the exact reference. |
| Equip a shared washroom | Compare run time, flow and protection against continuous flow. These address different needs from a private bathroom. |
Details that change the result
Compare a value, not just a logo
EcoSmart identifies flow-limiting products. Values differ by tap, shower and version. Compare two exact references at the same measurement pressure and with the same number of active outlets.
Think in litres per use
Example: moving from 12 to 8 l/min for 8 minutes means 32 fewer litres per shower. At two showers daily, that is 23,360 litres yearly. This assumes unchanged usage.
Separate water use from the bill
Financial savings depend on water tariffs, the hot-water share and the heating system. Start with litres saved; no fixed financial saving applies to every home.
