Water saving means costs saving
There are a number of possibilities to reduce the water consumption and therefore the costs. Apart from changes in the personal behaviour and regular maintenance of the sanitary installation there are plenty of effective, technical solutions that achieve water savings without any compromises in comfort.
Special attention lies thereby on "re-equipment" products which optimize existing armatures economically regarding the water consumption and the application comfort.
The significant reduction of the water quantity is one important aspect. Looking at the ever increasing costs for power, gas or oil, the other aspect lies in the significant saving on energy. Because the majority of the saved water is heated water used for washing hands or in the shower. Energy saving is sometimes even more economically sensible then the water saving itself.
The graph shows the water points at which you can save water effortless with technical means.
It is very simple and doesn't take much effort to save water on the following devices:
- at the faucet
- on the shower head
- inside the toilet water cistern
Aerator have many different names and brands. They are used to form and to areate the water jet. They are more and more standard in any household.
Common aerators, also the ones that come with the installation are using up to 16 liters per minute. Special water saving aerators are saving through quantity limiting, i.e. through quantity reduction you could save up to 70% on water and on energy for heating the warm water.
Through special technical means, e.g. jet propulsion and increased air injection it is hardly possible to spot the difference between the jet of an optimised faucet and the jet of a common aerator.
In combination with standard, non water saving shower heads you can save water by installing flow reducers. Those robust flow reducers are reducing through a specially reduced inner diameter the water passing through it. The more complex quantity flow reducer are regulating the flow independent of the pressure to an exact, pre configured flow rate.
Most of the "normal" shower heads however can only manage moderate savings. They are technically not designed to compensate the reduced flow - the result is a reduction in the shower comfort.
Water saving showers
If you consider water and energy saving you should really start with the shower. With a "normal" shower head you spend ca. 25 liters of warm water per minute. Assuming an average 3 minute shower every day you use 60 liters of good drinking water and about 2 kWh of energy. Per person and year that adds up to ? 160 for water and energy (on average prices for water and energy).
Water saving shower heads achieve lowest water and energy consumption without compromising the comfort factor by using a special turbulance principle. Compare to standard shower heads or wall showers you could save up to 50%. A positive side effect of this working principle is that the water jet is dispersed into many single, strongly accelerated drops and therefore have very little inclination of calcifying and a long durability of these showers.
The application of Toilet-WaterStop reduces the water consumption of the toilet flushing by up to 50% through manual regulation. The quantity of the flushing water can be adapted through the duration of the flushing. So for the "small" business you would only use 3 liters instead of 9 liters of valuable drinking water.
Also modern cisterns can be re-equipped. For a short flush you only need to press twice. The first one for starting the flush, the second for stopping the flush. After the installation of the Toilet-WaterStop the flushing stops automatically the moment you let the button go.
