What is the Eraslan 200 Litres Pressurized flat plate indirect Solar Water Heater?

The Eraslan 200 Litres Pressurized flat plate indirect Solar Water Heater is a solar-powered water heating system designed for homes, hotels, and small businesses. It uses sunlight to heat water, helping you save on electricity or gas bills. The 200-litre tank is large enough for a family of 4–6 people, providing hot water for showers, cleaning, and other needs.

The pressurized design means the water flows at a strong and steady pressure, similar to regular tap water. The flat plate refers to the solar collector design, which absorbs sunlight and transfers the heat to the water. Indirect means it uses a special heat transfer fluid inside the system, preventing the water inside the collector from freezing in cold weather.

How the System Works

Step 1: Sunlight hits the flat plate collector, and the collector absorbs heat from the sun’s rays
Step 2: The heat transfers to a special fluid that flows through copper pipes inside the collector
Step 3: The heat then moves to the water in the tank through a coil system, without mixing the water and fluid
Step 4: The insulated tank stores hot water for many hours, even at night or on cloudy days

Types of Solar Water Heaters

Solar water heaters come in different types, and the Eraslan 200 Litres Pressurized flat plate indirect Solar Water Heater belongs to a specific category

Flat Plate Collector Systems

These use a flat metal plate to absorb heat
They are good for areas with strong sunlight
They are long-lasting and require low maintenance

Evacuated Tube Systems

These use glass tubes with vacuum insulation
They perform better in cold climates but usually cost more

Direct Systems

Water flows directly through the collector
They are not suitable for areas with freezing temperatures

Indirect Systems

Use a heat transfer fluid instead of direct water heating
Best for cold or mixed climates
Protects against freezing and scaling

The Eraslan 200 Litres Pressurized flat plate indirect Solar Water Heater is an indirect flat plate pressurized system, making it efficient and strong for most homes
