Today, hot water is a critical need in residential buildings, commercial buildings, hotels, hospitals, and industries. One commonly used device for heating water is the fixed immersion heater, which plays an important role in many applications, from industrial processes to domestic water heating. Not holding an active BIS license is illegal and could result in confiscation at customs, heavy fines, or even a ban on the product.
What are Fixed Immersion Heaters under IS 302 Part 1: 2024/IEC 60335-1?
Fixed Immersion Heaters according to IS 302 (Part 1): 2024 / IEC 60335-1: 2020 is the category of electrical heating appliances fitted in water storage units, such as geysers used in homes, hot water tanks, and liquid-holding tanks in industries.
Unlike portable immersion rods, which are dipped into a bucket of water and removed afterwards, fixed immersion heaters are physically attached to the apparatus to heat the water or other liquids from the inside. These devices are controlled through the Quality Control Order (QCO) 2026 of the Department for Promotion of Industry and Internal Trade (DPIIT).
