We plugged our energy meter into a mains socket then plugged our iron into it. We had already entered our electricity price into the meter so it could give us a direct readout of running cost. Having topped up the iron with water, it was switched on to warm up, which took around one minute. The iron was then used to iron a huge pile of shirts – fifteen in all.
