· Close doors and vents in unused rooms. Any heat that’s been generated from either natural sunlight or heaters will remain inside each room, if you remember to make the small effort of closing doors or any vents. That way the heat is trapped inside, and you won’t be wasting valuable energy, and will prevent you from paying to heat uninhabited space.
· After using your oven, leave the door open. This is a smart way to heat your kitchen and any adjacent room, especially if you’re already using your oven, then there’s no sense of letting that heat go to waste. After you’re finished cooking, leave the oven door slightly open to allow your kitchen to be filled with amazing smelling food and warmth.
