I've heard conflicting reports. Apparently heating a geyser from cold uses more energy. Okay, so now that I've typed that sentence I'm thinking, perhaps it does use more energy, but using that energy at night when demand is low decreases the daytime/peak demand.Paulhttp://www.blogger.com/profile/12966010406158398187noreply@blogger.com
