[QUOTE="gbyleveldt, post: 51865, member: 122"] I'm a bit hungover, so being dense now, but I'm not really getting what you saying here Johan. All things being equal, you saying that it won't use less electricity keeping the geaser at a lower temperature? I do understand that you'll be using less hot water, as the water is warmer. But as I said before, the further you go up from ambient, the higher your losses are gonna be, and this is not linear. Just as a matter of interest, a geaser also doesn't keep it's temperature for very long, no matter how well insulated it is. In fact, I'll be surprised if you get 48Hrs out of it. Losses in the insulation of the pipes and the geaser is by no means insignificant. It would definitely be interesting seeing hard data here. I do agree that it's retarded to switch off your geaser during the day. I'm also of the opinion it takes less energy to maintain a temperature than to get up to it. [/QUOTE]
