Load-shedding heater

[Stonemason]

I thought last night in JHB was a good winter practice run.
My thoughts to keep warm:
Close curtains around sun down to keep heat in north facing rooms.
Keep doors closed to cold rooms in my case the kitchen is south facing and freezing.
Rugs under the cot, decent sleep sack and blankets if required.

You have the right idea.

Oil heaters maintain their temperature for quite a while after load shedding starts. Panel heaters also maintain some heat when there is no electricity but not as well as an oil heater. There is a link between early childhood asthma and gas appliances so keep that away from the baby.
