BIS Certification for Stationary Storage Type Electric Water Heaters: Complete Guide for Manufacturers in India

Introduction

Stationary Storage Type Electric Water Heaters, commonly known as electric storage geysers, are among the most widely used household appliances in residential buildings, hotels, hospitals, commercial establishments, educational institutions, and industrial facilities. These appliances store heated water in an insulated tank, ensuring a continuous supply of hot water for various applications.

Since electric water heaters operate using electricity and high temperatures, they must comply with stringent safety and quality standards to minimize the risks of electric shock, overheating, fire hazards, pressure-related failures, and water leakage.

To ensure consumer safety and product reliability, the Bureau of Indian Standards (BIS) has established certification requirements for Stationary Storage Type Electric Water Heaters under the applicable Indian Standards. Manufacturers covered under the relevant Quality Control Orders (QCOs) are required to obtain BIS Certification before manufacturing, importing, selling, or distributing these products in India.

BIS Certification demonstrates that the product has been tested and complies with prescribed Indian safety and performance standards.

What is BIS Certification?

The Bureau of Indian Standards (BIS) is India's National Standards Body responsible for developing standards and certifying products for quality, safety, and reliability.

Depending on the applicable Indian Standard and government notification, manufacturers may require certification under:

  • BIS ISI Certification (Scheme-I)
  • BIS Compulsory Registration Scheme (CRS) (where applicable)

The appropriate certification route depends on the product category and the applicable Indian Standard.

BIS Certification involves:

  • Product testing
  • Factory inspection (where applicable)
  • Quality management assessment
  • Periodic surveillance

What are Stationary Storage Type Electric Water Heaters?

Stationary Storage Type Electric Water Heaters are permanently installed appliances designed to heat and store water inside an insulated storage tank.

They are commonly available in capacities such as:

  • 10 Litres
  • 15 Litres
  • 25 Litres
  • 35 Litres
  • 50 Litres
  • 100 Litres and above

These appliances are widely used in:

  • Residential Apartments
  • Individual Houses
  • Hotels
  • Hospitals
  • Hostels
  • Commercial Buildings
  • Educational Institutions
  • Offices
  • Industrial Facilities

Why is BIS Certification Important?

Electric water heaters operate under high electrical loads and elevated temperatures. Poor-quality products may result in:

  • Electric shock
  • Fire hazards
  • Tank leakage
  • Pressure build-up
  • Overheating
  • Thermostat failure
  • Reduced energy efficiency
  • Property damage
  • Personal injury

BIS Certification ensures that manufacturers comply with Indian safety requirements before marketing their products.
