As the name suggest, Solar Hot Water is the principal of heating stored water by way of the sun’s rays and energy. The water is stored in a tank and the suns energy is collected through solar collectors, mounted on the roof and in the direct sunlight. The suns energy is absorbed by the collectors and transferred to the water in the tank (by various means), heating the water. Its clean, energy efficient and a practical way to heat water.
Solar hot water these days come in many shapes, sizes and styles. From roof mounted tanks and collectors, to split systems where the collectors are mounted on the roof and the tanks are at ground level, there are options to suit almost every application and location.
The process behind transferring the suns energy to the tank can vary depending on the manufacture of the heater and type of heater. There is not one that is typically better than the other, however there are types better suited to specific climates.
