Savings, for the planet… and for the bills. This is what the government is ordering us to do with its call for sobriety while energy prices explode due to the war in Ukraine and the French nuclear fleet at half-mast. And if we talk a lot about heating, water consumption could also be very expensive.

To prevent this, local authorities are taking the initiative and distributing foamers to their constituents. These water flow restrictors will reduce the bill, while Ademe (Environmental Transition Agency) estimates that 12% of household energy consumption is used to heat water. For example, to calculate the cost of a shower, you need to add the cost of water consumption and the cost of electricity or gas used by the water heater.

Communities will be involved

In Rennes, the Eau du Bassin community already offers free aerators to all subscribers who request them. He asked 20 minutesits director Laurent Géneau believes that “if everyone reduces their consumption by 10%, there will be significant savings”.

In Nantes, all households will be able to obtain foaming agents for free from 2023, our colleagues inform usNantes news. These foamers are also readily available commercially.

What is the frother used for?

Technically speaking, “the aerator is used to add air to the water. (…) The action results in the water “foaming”, he explains Izy from EDF. In effect, the system “directs the flow of water into a clean and very directive stream.”

The system reduces water flow from faucets in the kitchen and bathroom by 30-60%. Either big savings achieved without any reduction in comfort, manufacturers and elected officials promise. A standard tap delivers 12 liters per minute. With the aerator, the flow rate can be reduced to 8 to 4 liters per minute.

Same story for the shower though Water Information Center (CIEAU) estimates that it uses an average of 15 to 20 liters per minute, or 75 to 100 liters for a 5-minute shower.

How to install the frother?

The aerators are screwed inside (male aerators) or outside (female aerators) the goose neck at the end of the tube. Male aerators are “generally used for shower faucets,” while female aerators “are more common in the kitchen,” according to EDF’s Izy. Attention, there are different diameters. Before installing the aerator, check that your batteries no longer have it. More and more systems are equipped with it.

Regarding the shower, since the consumption depends on the equipment used, it may be useful to first calculate the flow rate of the shower. To do this, just let the water in the container flow for a minute and monitor the amount at the end. You will then know whether the consumption of your shower head is “normal” or economical and whether the installation of a mousseur is necessary.

Have some reflexes

Turning off the faucet while brushing your teeth and hands helps to “reduce [sa] water consumption in half”, he assures Engie. The Water Information Center apparently recommends showering rather than bathing, limiting showering to 2 to 3 minutes of song duration, and “turning off the faucet” when soaping. In 2015, a survey commissioned by spol Ocean Press revealed that the French spend an average of 9 minutes in the shower.
