Wrap your hot water heater in a blanket. Saves energy and keeps the hot water hotter so you waste less water and energy getting to the hot water.
So you've already done that ... Go tankless. With traditional hot water heaters you heat a tank of water which gets cold waiting for that one shower a day, then you go through the cold water to get to the hot water. Tankless heaters only heat the water you need.
Less energy, less water.
