According to the graphic, shutting of the water when brushing teeth saves 7 to 10 liters of water per minute. Although it is a good idea to shut off the water while brushing teeth, that figure is far greater than it should be. For the faucet (tap) to waste that much water, the flow rate would have to be set quite high, in fact, higher than most people would set it. If the flow rate were set only high enough to get the tooth brush wet, the amount of water wasted would be much less than one liter per minute which is a tiny fraction as much as claimed.
Anyone who doubts this can test it for himself. All it takes is a measuring cup and a watch. Try setting the flow rate for various amounts and measuring it.
The graphic also recommends against drying clothes on a radiator, asserting that it makes the boiler work harder and makes the house too damp. That may be true in England, but it most definitely is not true in many parts of the U.S. Here in the U.S., in many places, the humidity in winter is too low (the RH in a house can even be lower than 20%) so the added moisture would be welcome. And, drying clothes on a radiator in a dry climate would not make the boiler work harder than operating a humidifier since a humidifier also works by evaporation which absorbs heat.
Many of the ideas are good, but one must use some judgment. A lot depends on location and circumstances.
