When washing dishes, do not use too much hot water. Rather than pouring water at a loss, to do the dishes, it is better to close the bung. It saves 12770 L of hot water / year with one dish per day and about 61 € of electricity!

On my washing machine, I save with the cycle at 30 ° C. 80% of the electricity used by my washing machine is used to heat the water: washing at 30 ° C instead of 40 °, I save 11% of energy each cycle. And instead of prewash , I soak my dirty clothes in a basin of water mixed with percarbonate (2 to 3 tablespoons of sodium percarbonate / l of hot water): hop, I reduce again from 15 to 20 % energy consumption.

On my boiler, I choose the most economical thermostat. I set the thermostat to 50-55 ° C (either the temperature is displayed on it, or I measure the temperature of the hot water at the tap outlet with a cooking thermometer). I also reduce my energy bill by 10 to 20% when I draw hot water. And I cover my hot water pipes with a rubber sleeve (from 1.49 € / m Castorama ) to prevent the loss of heat that rises to 10% without insulation.
