You need heat

• Change into warm clothes. Don’t forget your head.
• Candles will raise the temperature in the room. Use stable, incombustible candle holders. You can also stand the candles in a bowl of water so that they will go out when they have burned down.

Move the whole family into one room to put your body heat to use. 

• The room should preferably face south.
• Shut the venetian blinds, draw the curtains and hang a blanket in front of the window to keep the heat in.

If it’s very cold, arrange a “hut” under a table.

• Cover the table with blankets that hang down to the floor.
• Place mattresses on the floor, and get the whole family to “live in the hut”.
• A sleeping bag may be sufficient to keep yourself warm overnight. If you have facilities for heating water, you can fill a bottle with warm water, slip the bottle into a sock and use it as a hot-water bottle to warm up the sleeping bags.

If you have a heating stove, use it. 

• Carefully read the user instructions if you intend to use a portable stove, such as an LPG stove.
• Anything that burns absorbs oxygen from the air. So make sure that you air the house regularly. The ventilation system of the house will often stop working after a power cut. But the ventilation will not be affected if your house has natural draught ventilation.
• Check that the fire alarm is working.
