500 Liter Solar Water Heater With Complete Details
The 500 liter solar water heaters are huge capacity water heating devices that use the thermosiphon principle to convert sunlight into heat energy. With this solar water heater, you can convert 500L of cold water to water at 60-80 degrees Celsius temperature. 500 liter is the maximum capacity in standard company fitted SWH (solar water heater). It is easy to use and easy to install, there is no maintenance required (except cleaning). It does not require costly electricity to heat water.
A solar water heater has an array of solar power collectors to collect solar energy and an insulated tank for storing hot water. Both are related to each other. In the daytime, the water is heated in solar collectors. It is then pumped or automatically flown into storage tanks with the thermosiphon principle.

#2. Types of 500L Water Heater
Solar energy provides clear, constant and safe advantages. It is undoubtedly the focus of attention for better energy source seekers and hence solar gadgets including solar water heaters are getting further advanced every day.
Depending upon the type of collector used in the system, there are two types of solar water heating systems: the first is an evacuated tube collector (ETC) and the second one is a flat plate collector (FPC).
A collector of a solar water heater is the heart of the system. It absorbs the sunlight and initiates the water heating process. A change in the design of the collector ends up creating a different type of solar water heater.
The FPC solar water heater is further divided into 4 types-
- Non Pressurized or Standard (NPX)
- Pressurized (Px.)
- Heat Exchanger (HE)
- Pressurized with heat exchanger (Px. HE)
#3. ETC 500 Liter Water Heater
ETC stands for Evacuated Tube Collector. That indicates the ETC solar water heater is equipped with glass tubes to absorb the sunlight to heat the cold water. The 3T tube, having multiple layers, is employed to trap the vacuum which works as an efficient insulator for warming the water. It has a coating of the fin to absorb the radiation and ensure minimum heat loss.
Evacuated tube collector (ETC) 500-liter solar water heater systems are cheaper than flat plate collector (FPC) based systems. They perform better in cold regions up to zero degree temperature. These solar water heaters are found useful mainly for commercial purposes.

#6. FPC HE 500L Solar Water Heater
In FCP heat exchanger 500 liter solar water heater, the air is evacuated from the solar tube to create a vacuum. FPC-based systems perform well with anti-freeze solutions at subzero temperatures but increase their cost. In other areas, both perform equally well. This greatly reduces conductive and convective heat losses from the interior of the tube. The resulting air and cold temperatures have less effect on the efficiency of the empty tube collector.
In an FPC HE 500L solar water heater, the heat is exchanged from a certain medium to cold water resulting in producing hot water. It is ideal for areas having hard water.
