A month or so ago I bought a pump-flask!! Turns out to be a great buy, instead of boiling the kettle numerous times each day, I boil a kettle full first thing then empty it in the thermos flask to be used throughout the day. Hot drinks or boiling water for cooking the veggies. Saves electric and time!! Any water left in the flask at night is decanted into a bottle for watering plants or swilling dishes.
