Upgrade to a tankless water heater
A typical water heater continually heats water in a storage tank so that it is always available — similar to keeping your coffee pot warm all day. An on demand water heater is more efficient because it does not have a tank. Instead, it creates hot water only when needed or "on demand," thus reducing the heat loss associated with a traditional water heater.
