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.

#4. FPC 300 Liter Water Heater

The FPC 300 liter solar water heater has absorber sheets inside a metallic box that is insulated. This type of solar water heater with flat plate collector is probably the most fundamental and most studied technique for solar power domestic hot water systems. 

The overall idea behind this technique is very simple. The sun heats a dark flat surface, which collects as much energy as possible, and the energy is transferred to water, air, or other liquids for further use. Also, FPC allows the customers to choose from several different featured types of solar water heater. The types are discussed below.

#5. FPC Px 300L Solar Water Heater

FCP pressurized 300 liter solar water heater has copper pipes bonded or soldered directly to the adsorption plate to ensure maximum surface contact and heat transfer. The sunlight heats the absorbed surface, raising the temperature. As the plate heats, this heat is conducted through the risers and absorbed by the fluid flowing inside the copper pipe which is then used by the house.

In simple words, the FPC PX 300L solar water heaters work by exerting pressure on the system to heat water in a heating unit that is closed from every side. The water is pumped constantly through the solar collectors using the closed-loop and circulation pump that come with the system. So using this system, you can enjoy hot water at every instant.
