5 washes-week. Four at 30 degrees. one at 60 degrees. Win Win Win. All our washes used to be at 40 or 60 degrees. The percentage saving in energy terms of 40 percent will reduce our bills so much....haven't yet worked it out...but this is significant. The activity has prompted me to look at all the different programmes rather than just using the same one. Now using faster washes....less water and time and reducing detergent...oh this is win win win situation.
