The second biggest energy guzzler in the home behind heating is the use of water. A five-minute hot shower without a water-saving shower head (approx. 18 litres/minute) consumes around 3 dl heating oil or approximately 3 kW/h. Or to put it another way, around the same amount of electricity needed to charge your smartphone every day for seven months. That’s incredible, right? It is thus all the more important that we reduce the amount of hot water we consume. Fortunately, we can do this with almost no loss of comfort thanks to the clever water-saving products from Neoperl and Amphiro.
