How the water heater functions
Sunlight is absorbed by a collector that is placed on the roof which then changes it to heat. A circulating pump then transfers the heat to a water tank through the aid of a thermal regulator. This happens only when the collector is hotter than the water in the tank to avoid overheating.
It has a backup system that heats water to the required temperature when there is not enough sunlight. This is beneficial during rainy seasons.
