Advance Information*

Overview of 250LPD ETC (Airvent) Solar Water Heater

The 250LPD ETC (Airvent) Solar Water Heater from Kamal Solar is a cutting-edge solution designed to provide efficient and eco-friendly hot water for residential and small-scale commercial use. Engineered with advanced technology and high-quality materials, this solar water heater offers reliable performance and long-lasting durability.

Key Features and Specifications

Capacity

• 250 Liters Per Day (LPD): The unit can heat up to 250 liters of water per day, making it suitable for households with a single bathroom, serving up to 5 people comfortably.

Inner Tank

• Material: The inner tank is constructed from Stainless Steel (Food Grade 304L). This high-quality material ensures that the water remains safe and free from contamination while also resisting corrosion and scaling.

Outer Cladding

• Material: The outer cladding is made from a Colour Coated Sheet. This provides an additional layer of protection against the elements, enhancing the unit’s durability.

Insulation

• Polyurethane Foam (PUF): The tank is insulated with thick, high-density PUF, which minimizes heat loss and maintains the water temperature for an extended period, even during cloudy days.

Hermetic Sealing Rings

• Silicon Rings: These are used as hermetic sealing rings, ensuring the system remains airtight. This helps in maintaining the vacuum within the tubes and improving the efficiency of the heater.

Evacuated Tube Material and Specifications

• Material: The evacuated tubes are crafted from Borosilicate Glass. Known for its high resistance to thermal shock and durability, this glass ensures optimal performance.
• Diameter: Each tube has a diameter of 58mm.
• Length: The length of each tube is 1800mm.
• Thickness: The wall thickness of the tubes is 1.6mm.
• Number of Tubes: The system includes 25 evacuated tubes, which collectively absorb and convert solar energy into heat efficiently.

Stand

• Material: The stand is manufactured from Colour Coated GI Sheet. This provides robust support to the system and resists weather-related wear and tear.

Electrical Backup

• Availability: There is an Optional Electrical Backup available for additional charges. This feature ensures that you have a reliable hot water supply even during prolonged cloudy or rainy periods.

Efficiency and Performance

The 250LPD ETC (Airvent) Solar Water Heater employs Evacuated Tube Collector (ETC) technology, which is known for high efficiency in converting solar energy into heat. The evacuated tubes operate by creating a vacuum that minimizes heat loss, allowing for higher temperature water production even in cooler ambient conditions. This makes the system especially effective in regions with variable weather patterns.

Environmental Impact

Using solar energy for water heating reduces dependence on conventional energy sources like electricity or gas, significantly cutting down on carbon emissions. The use of food-grade stainless steel, borosilicate glass, and durable materials ensures that the system is eco-friendly and does not pose a threat to the environment over its operational lifetime.

Installation and Maintenance

The setup of the 250LPD ETC (Airvent) Solar Water Heater is straightforward and requires minimal maintenance. The robust materials and high-quality construction reduce the need for frequent servicing. The silicon hermetic sealing rings and high-density insulation further simplify maintenance by enhancing the unit's longevity and operational efficiency.
