iirc, heat loss through the wall of the tank and insulation will be approximately proportional to the absolute temperature difference between the water and ambient temp outside the unit. which is why KN is saying the loss is greater if you maintain a higher temp.

also, if you keep a home air-conditioned, then every heat source in the home is more heat that the heat pump has to pump out. so there may be an additional energy loss there.
