🛡️ 20 Years Guarantee ✅ BIS Certified
(Approved by Ministry, Govt. of India)

What is Glass Lining?

Glass Lining is a high-temperature (around 850°C) non-stick coating process, where special glass material is melted and fused onto the tank surface in an automatic furnace. This internationally recognized technology ensures clean, hygienic hot water and extends the life of the tank by making it rust-free.

Why Choose Kamal Solar Glass Lined Water Heaters?

FAQ on Kamal Solar Glass Lined ETC Solar Water Heater
What is an ETC solar water heater?
An ETC (Evacuated Tube Collector) solar water heater uses vacuum tubes to absorb solar energy and heat water. The vacuum between the inner and outer tube minimizes heat loss, making it efficient even in colder or cloudy conditions.
How does the ETC system differ from FPC systems?
While both are solar water heaters, ETC systems use vacuum tubes, making them more efficient in colder regions and requiring less maintenance. FPC systems use flat plates and are more suitable for higher pressure and large-scale installations.
What is the benefit of glass lining in ETC water heaters?
The glass lining inside the tank prevents rust, scaling, and bacterial growth. It ensures hygienic water and greatly extends the lifespan of the tank, especially when using hard or borewell water.
Is the Kamal Solar ETC system suitable for hard water?
Yes, a sturdy support structure is essential to securely mount the tank and the FPC panels. The structure must be designed to bear the tank's weight when filled with water and to withstand wind loads.
What is the life expectancy of the system?
Kamal Solar offers a 20-year guarantee on the glass-lined tank. With proper installation and minimal maintenance, the system can last over 20 years.
How long does the water remain hot?
Thanks to high-density PUF insulation, the water remains hot for up to 72 hours, depending on usage and weather.
Does it work during cloudy or rainy days?
Partially. On cloudy days, it will still generate some heat. However, for full heating, a hybrid electric backup can be installed, which Kamal Solar systems are compatible with.
Can I use it with pressure pumps or modern showers?
Yes. The Kamal Solar ETC model is designed to deliver consistent pressure, making it suitable for modern bathrooms and premium fittings.
What capacities are available?
ETC systems are available in 100L, 150L, 200L, 250L, 300L, 500L, and 1000L models, catering to both residential and commercial needs.
Is it approved by the government?
Yes. Kamal Solar's ETC model is approved by the Ministry of New and Renewable Energy (MNRE) and is BIS certified, meeting all national standards.
Is installation support provided?
Yes. Kamal Solar provides end-to-end support, including site survey, installation, and after-sales service across multiple locations.
Does it require regular maintenance?
Minimal maintenance is required. A basic annual check-up is sufficient, thanks to the non-stick, anti-corrosion glass-lined inner tank and self-cleaning vacuum tubes.
