heat

about saving power then consider this. Your Hot water cylinder when turned on only operates at one speed. That is flat out. Whenever the thermostat trips then it only knows flat out.

Let all that roasting hot air out after you cook in the oven! It's so much better than wasting all that heat behind a closed oven door.

On a warm sunny days pull up the blinds, draw back the net curtains and you will be surprised how much warmer the house is because of the sunlight streaming in.

Weather outside LOOK terrible - maybe the kids are at a loose end?

Have you looked out your window? Are your trees blocking the sun from shining into your house?
