It depends on how you use hot water (bath, shower, dishes, etc.), when you use hot water, and how well your geyser insulation.<BR/><BR/>When we moved into our house the geyser was set at 55º, but that was a little low, so I tuned it up a bit.<BR/><BR/>With your thermostat a bit lower you will conserve a small amount of energy and also cause your geyser to be on a little less.<BR/><BR/>Insulation of your geyser and pipes will be the biggest win in my opinion.<BR/><BR/>Hmmm, you run a electrical inspection company....I wonder if the clients would mind if you tuned all the geysers you inspect down by 5º? ;)Duncan Drennanhttp://www.blogger.com/profile/18356141566912975917noreply@blogger.com
