A 300L solar water heater is ideal to provide hot water to a medium home with 5-6 members having 2-3 bathrooms. This solar water heater used to heat water by trapping it in the heat of sunlight. With a robust, reliable construction and advanced technology, the solar water heater creates a stress free and user friendly experience.
The solar collectors use the sunlight to generate solar heat which is absorbed by flowing water. This makes the water hot. The hot water is carried to the 300L water tank for storing and keeping it hot overnight. Talking about the dimensions, a 300 LPD ETC solar water heater comes with 1800 mm length, 58 mm dia, and 30 tubes (in ETC type) made with high grade steel.
