Overview
This page provides BIS (ISI) certification guidance for electric instantaneous water heatersused in household and similar installations. The applicable Indian Standard prescribes safety, construction, performance, and marking requirements to ensure electrical safety and reliable hot-water delivery.
With BIS Certification, manufacturers and brand owners demonstrate compliance with national safety benchmarks, supporting market access, tender eligibility, and consumer trust.
At GiBS, we handle documentation, type testing, factory inspection readiness, and coordination until license grant—minimizing delays and rework.

- Electrical Safety – Protection against shock, insulation, creepage/clearance, and earthing continuity.
- Construction – Heating elements, pressure-capable water path, thermostat/thermal cut-out, NRV/PRV (as applicable), robust enclosures.
- Performance – Declared power rating, minimum flow vs. temperature rise, inlet conditions, duty cycle suitability.
- Controls & Protection – Accurate temperature limitation to prevent scalding; pressure/over-temperature safety devices.
- Supply & Wiring – Corded or fixed wiring requirements; terminals, strain relief, and earthing provisions.
- Marking & Instructions – Ratings (V/Hz/W), protection class, symbols, installation/user safety instructions.
- Ingress & Location – IP rating where required; safe mounting distances in wet areas.
Certification Process
- Application – Models/variants, ratings, BoM, circuit/enclosure details, draft labels, QC plan.
- Type Testing – Electrical safety, performance, ingress/environmental, and marking evaluations.
- Factory Inspection – Incoming QC, line safety jigs/fixtures, calibration records, routine/acceptance tests, traceability.
- License Grant – CM/L issuance; ISI marking finalized.
- Surveillance – Periodic audits and samples from plant/market for ongoing conformity.
