Hot water bottles are old fashioned but warm. Nothing heats up the bed faster. You can turn down the heat and keep warm. So environmentally friendly.
It's cold outside in the UK so The Guardian has written a very ecological and very English ode to the water bottle this week:
Hot-water bottles are never going to be fashionable. Even to talk about them is to invite a smirk from your audience. And yet would anyone turn down the offer of a hot-water bottle in this weather? Cheaper and greener than leaving the heating on all night, a bottle is a portable comfort.
With a little planning, it heats up the bed before you clamber in. With an adequate cover (and would you seriously consider a naked rubber bottle?), it keeps you warm into the small hours. And then there is the attendant ritual of decanting a boiled kettle; lightly burping the bottle, and screwing the cap reassuringly tight.
To do this is to feel somehow parental, wise – as if providing for your inner child. Like a cup of breakfast tea in bed, or a hot bath after a long day, a hot-water bottle is the kind of prosaic comfort that is easy to overlook and yet somehow makes life so much better. In fashion? Never. A must-have? Absolutely.
