A useful tip is to place aluminium foil behind all radiators attached to outside walls.
By fixing a shelf on top, the warm air from the radiator is deflected into the middle of
the room.
Set the switch to turn the heating on approximately half an hour before you get home at
night or get up in the morning. Similarly, set the switch to turn the heating off
approximately half an hour before you leave home or go to bed. This is a simple way to
conserve heat in a room.
