Sadly I know that some people have given up keeping their homes warm and turned their heating off, they were wearing jumpers and coats in their own home. They're in danger of freezing to death, their homes have become like coffins. I don't know how long this warm spell will last for. I hope the whole of winter is like this. I don't want to learn of people freezing to death in their homes.
I would advise people that can't afford to heat their homes to turn the thermostat to 7°c so their pipes don't freeze and burst open. Then they can use an electric blanket on their sofa and bed. Electric blankets don't use much power. They could also perch their toaster infront of them and turn it on with no bread, the plume of heat would help and electric toasters don't use much power. I would also advise putting potatoes in the microwave. Jacket potatoes store a large amount of heat, the heat would spread out from the microwave and help a bit, plus potatoes are full of starch, lots of energy.
Keep your chin up guys. Let's stay hopeful of a bright 2023.
