Energy-saving tips

Turn to the right temperature
It is usually a waste of energy to turn the heating on full in every room. A simple adjustment of the thermostat could save you a lot of money. 20 to 21 degrees Celsius are sufficient in your living room, children's room and study, the temperature in your kitchen, bedroom and hallway can be 2 degrees less and 2 degrees more in your bathroom . A temperature of 12 degrees Celsius is usually sufficient in unused rooms.
