Electric Instantaneous Water Heaters
summary
Electric Instantaneous Water Heaters are appliances that heat water instantly as it flows through the unit without storing it. They use electric heating elements to provide on-demand hot water for bathrooms and kitchens. These heaters are compact, energy-efficient, and suitable for residential and commercial applications.
Why BIS Certificate is Mandatory for Electric Instantaneous Water Heaters
BIS certification is mandatory to ensure electric instantaneous water heaters meet prescribed Indian safety and performance standards. Since they operate with high electrical load and direct water contact, certification prevents risks such as electric shock, overheating, fire hazards, insulation failure, and unsafe installation practices in households.
What is BIS Certified for Electric Instantaneous Water Heaters
The BIS certified specification defines requirements for electrical safety, construction, insulation resistance, earthing, temperature rise limits, performance testing, marking, and protection against electric shock. It ensures electric instantaneous water heaters comply with relevant Indian Standards, guaranteeing safe operation, durability, and reliable heating performance.
