Hi.
I have a geyserwise installed, and to save power now in the winter we heat up the geyser to about 55 degrees and then turn it off by the main breakers. But after about and hour or 2 when we turn it on again the temperature drop till about 25 degrees. We even covered the geyser with a geyser blanket but the temperature still keeps dropping after we switch it off. Does anyone have any suggestions or a reason why this is happening.
