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

#4. FPC 500 Liter Water Heater

FPC stands for Flat Plate Collector. That means the collector used in this kind of solar water heater is a flat plate. There is an insulated rectangular box coated with glass under which several copper pipes are held interconnected to let the water flow through. Inside are black metallic absorbent sheets that are manufactured in channels or riser tubes to carry water. The absorber absorbs solar radiation and transfers heat to the flowing water. You can either have a glazed flat-plate collector with plastic or glass cover or an unglazed flat-plate collector with no cover.

#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.

Frequently Asked Question

500 L solar water heater (SWH) can work in any climate. Temperature of hot water will depend upon how much sunlight is available.

Solar water heaters are a kind of geyser that runs by absorbing the sunlight. In winters, you can use these heaters to warm water by placing the collector of the system under the sun.

FPC solar water heater is the most popular kind of solar water heating system. It uses a flat-plate collector to absorb the sunlight with maximum efficiency. The heater is extremely durable, easy-to-install and cost-effective. Besides, it provides an option to choose from four different types of FPC solar water heaters.

Solar water heaters, once installed, require very little maintenance. Maintenance involves wiping out the dust deposited on the glass surface once in 5 days

ETC solar water heater has smooth glass tubes, so there is no matter of hard water.

It is sufficient for up to 8 family members and 3-5 bathrooms.

You can easily remove and replace any glass tube. It costs around Rs. 500.

Solar water heating system works on the thermosyphon principle. The collectors present in the system absorb the radiations coming from the sun and heat the water. This water flows through the connecting pipes and gets stored inside the insulated storage tank. 

Using a solar system with an electric geyser is a very cost-effective option for residences. Just pair up a set of solar panels to the electric geyser making a solar system. This way, you can cover the energy costs of your home to some extent.

It depend upon weather of you are. You can contact us for guidance or more queries.
