1. A water purification device, comprising:
a feed water reservoir configured to store feed water;
a water vapor chamber configured to receive water vapor generated from heating the feed water in the feed water reservoir;
a condensation chamber configured to receive the water vapor and condense the water vapor into purified water;
a Peltier device comprising a hot side and a cold side, wherein the Peltier device is configured to receive a voltage from a power source and create a temperature difference between the hot side and the cold side, wherein the hot side is configured to heat the feed water into water vapor and the cold side is configured to condense the water vapor into purified water;
a set of one or more temperature sensors configured to measure a temperature of the feed water inside the feed water reservoir;
a set of one or more electrically heated auxiliary heating elements made of metal, the electrically heated auxiliary heating elements configured to heat the feed water into water vapor; and
a controller configured to:
receive temperature measurements from the set of one or more temperature sensors;
determine, based on the temperature measurements, a rate of change of temperature of the feed water inside the feed water reservoir caused by the hot side of the Peltier device heating the feed water into water vapor;
determine, based on at least the rate of change of temperature, an amount of water that will be purified in a predetermined amount of time; and
turn on power to the set of one or more electrically heated auxiliary heating elements when the amount of water that will be purified is determined to be below a threshold.
