Sparduschkopf in the test: How much does it really save?
In Sparduschkopf is one of the most effective savings measures that can be implemented at home – once installed, savings are made with every shower. And it’s also easy to install. However, it is not always easy to distinguish a water-saving shower head from a conventional one. Tips for buying can be found here.
Does a savings shower head also make sense in my home?
Whether and how much you would save with an economy shower head, you can find out with our calculator – in kilowatt hours, euros and kilograms of CO2.
Note that your financial savings potential can be significantly higher than stated in the calculator, as current energy prices are above average. For better orientation, you can multiply the number of kilowatt hours saved by the consumption price of your energy tariff.
Sparduschkopf – Tips for the purchase
If you also want to save water in the future with an economy shower head, consider the following things when buying:
Flow rate: In order to really find a water-saving shower head, pay attention to the indication of the bulk quantity or the flow rate per minute. Designations such as “eco” or “economical” give indications of an efficient shower head, but no guarantee for it. Shower showers with a flow rate of about 5 to 6 litres or more are water-saving. Conventional shower heads consume at least two to three times as much.
Threads and connections: There are standardized threads and connections for shower heads, so you do not have to take them into account when making your purchase decision.
Water pressure: Depending on what the actual water pressure is with you, you save a little more or less water. On average, the water pressure is 3 bar, to which the stated values also refer.
Economy shower head and hydraulic instantaneous water heater
With a hydraulic instantaneous water heater, problems with water heating can occur with economy shower heads. This is because hydraulic instantaneous water heaters work with the water pressure or with the flow rate. If the pressure and/or flow rate is too low, the instantaneous water heater may not turn on to heat the water – because with such a small amount, the water would be boiling hot in a few seconds. Depending on the model, a hydraulic instantaneous water heater needs at least 8 liters of flow per minute. It is best to inform yourself about this from the manufacturer.
