Embodiments of the present disclosure generally pertain to systems and methods for estimating and indicating temperature characteristics of temperature controlled liquids. A system in accordance with one exemplary embodiment of the present disclosure has a tank filled at least partially with a liquid, such as water, and the system has a plurality of temperature sensors mounted on the tank. During operation, a controller compares temperatures sensed by these temperature sensors to a predefined temperature profile for the liquid within the tank in order to estimate the likely temperature characteristics of such liquid. The controller then reports these estimated temperature characteristics via a user interface. As an example, the controller may estimate and report the amount of liquid above a threshold temperature that can be drawn from the tank. Based on the reported temperature characteristics, a user may make decisions about whether or how to use liquid drawn from the tank.
