Having less-warm water in your geyser will make you use more of it (usually you use more water from the cold pipe to even out the final temperature). This then requires more cold water to be heated again in the geyser. I'm sure there is some optimal point, though, because you also don't need to heat the "fresh" water as much as with a hotter setting. But, I haven't done the calculations yet.Francois Cilliersnoreply@blogger.com
