Everything You Need to Know About BIS for Water Heating Appliances
In today’s modern homes, water heating appliances are essential for daily comfort and convenience. Whether it’s an electric geyser, a solar heater, or a gas water heater, safety and quality are crucial. In India, these standards are maintained by the Bureau of Indian Standards (BIS), which governs the certification process for various products, including domestic water heating appliances. This blog will help you understand what BIS for Water Heating Appliances is, why it is mandatory, and how to obtain the certification.
What is BIS Certification?
BIS Certification is a process by which the Bureau of Indian Standards ensures that a product meets the required quality, safety, and performance benchmarks as laid out by Indian standards. This certification is mandatory for certain products, especially those that are safety-sensitive or impact public health. Electrical appliances, including water heating appliances, fall under this category.
Manufacturers who wish to sell or distribute water heating appliances in India must comply with BIS norms. The BIS not only checks for quality assurance but also evaluates the product’s durability and safety, particularly when exposed to electricity and water.
Why BIS Certification for Water Heating Appliances is Important
Water heating appliances are widely used across Indian households, especially during winters. Faulty or low-quality devices can lead to electric shocks, fire hazards, or serious accidents. Hence, the BIS has made it mandatory for certain water heating appliances to meet predefined standards.
Here are the key reasons why BIS certification is essential:
-
Consumer Safety: Certified appliances are tested for safe operation, reducing risks of shocks or fire.
-
Energy Efficiency: BIS ensures that certified products are energy-efficient and environmentally friendly.
-
Market Trust: Products with BIS certification gain higher trust from distributors and customers.
-
Legal Compliance: Selling non-BIS certified products in India where mandatory standards apply can result in legal action or bans.
-
Export Opportunities: BIS-certified products are often more acceptable in international markets.
Standards Applicable for Water Heating Appliances
The Indian Standards (IS) codes applicable to domestic water heating appliances include:
-
IS 2082: Specification for Electric Storage Water Heaters
-
IS 8978: Specification for Instantaneous Electric Water Heaters
-
IS 302-2-21: Safety for Household and Similar Electrical Appliances – Water Heaters
These standards specify safety features, construction quality, testing methods, and performance requirements for various types of water heating appliances.
Types of Water Heating Appliances Covered
BIS certification is generally mandatory for the following types of domestic water heating appliances:
-
Electric Storage Water Heaters
-
Instantaneous Electric Water Heaters
-
Solar Water Heaters (in some categories)
-
Gas Geysers
-
Immersion Rods
These appliances are tested based on their structural integrity, insulation resistance, water pressure handling capacity, and heating element safety.
Understanding the ISI Mark for Electrical Water Heating Appliances
The ISI Mark for Electrical Water Heating Appliances is the most visible proof that the product has met the BIS standards. This mark, issued by BIS, must be displayed on the product, its packaging, and promotional materials. It contains the license number and the applicable IS code.
Here’s what the ISI mark ensures:
-
The manufacturer holds a valid BIS license.
-
The product is manufactured under a quality control system.
-
It is subjected to periodic factory inspections and market surveillance.
-
The manufacturer follows testing procedures as per BIS norms.
Using or selling products without a valid ISI mark in cases where it's mandatory is a punishable offense under the BIS Act, 2016.
Who Needs to Apply for BIS Certification?
The following entities need to obtain BIS certification for domestic water heating appliances:
-
Indian manufacturers of electric or gas water heaters
-
Importers of foreign-manufactured water heating appliances
-
OEM suppliers producing under another brand name
-
Exporters intending to market water heaters in India
Even if the product is manufactured abroad, BIS certification is mandatory for its sale in India.
How to Apply for ISI Certification for Water Heating Appliances
The process to obtain ISI Certification for Water Heating Appliances involves several steps:
Step 1: Product Testing
The product must be tested in a BIS-recognized laboratory for the relevant Indian Standard. The test results should show compliance with all safety and performance parameters.

Step 3: Factory Inspection
BIS officials conduct a physical inspection of the factory to assess quality control measures and manufacturing capability. During the visit, random samples may also be picked up for independent testing.
Step 4: Grant of License
If all checks are satisfactory, BIS issues a certification license, along with permission to use the ISI mark.
Validity and Renewal of BIS License
The initial license is usually valid for one year and can be renewed periodically. To ensure continued compliance, BIS conducts surprise inspections and testing even after the license has been issued.
Cost Involved in BIS Certification
The cost of BIS certification depends on several factors, including:
-
Testing fees for each model
-
Application fee and processing charges
-
Inspection charges
