Heating this water costs energy, which you have to pay for. With water- saving faucet aerators and flow regulators for the shower, your water consumption and energy bills can be significantly reduced. Our water and energy saving calculator tells you just how great that reduction could be.
How the water and energy saving calculator works
Simply enter how many people live in your household and how long your shower, washbasin and kitchen faucets are used on average per person each day. Based on this information, the calculator estimates how installing aerators or flow regulators may influence water consumption, energy use and household costs.
The calculations are based on statistical averages and the information you provide. Actual results may vary depending on the product, installation conditions and individual usage habits. For more personalised estimates, open the advanced settings via the gear icon and adjust the underlying assumptions to match your situation.
