India: BEE Revises Star Labelling for Electric Water Heaters

India Tightens BEE Star Labelling for Electric Water Heaters

India's Bureau of Energy Efficiency (BEE), the statutory body under the Ministry of Power, has revised the Star Labelling requirements for stationary storage type electric water heaters, commonly sold as electric geysers, under its Standards & Labelling (S&L) Programme. The revision updates the star rating table and the label validity period for the category, raising the minimum energy performance level required to qualify for each star band.

For manufacturers, importers and existing permit holders, the practical effect is straightforward: a model that carried a given star rating under the previous norms will not automatically retain that rating, and affected products will need to be re-registered under the revised table to remain compliant and saleable in India.

Regulatory context

The S&L Programme was launched in 2006 under the Energy Conservation Act, 2001, and is administered by BEE. Stationary storage type electric water heaters are one of the categories under mandatory star labelling, meaning a valid BEE registration and star label are a condition of sale in the Indian market. The category is governed by Indian Standard IS 2082 and administered through BEE's Schedule 10, with the energy-performance framework rooted in the base notification S.O. 2902(E) dated 7 September 2016.

BEE operates the programme on an "efficiency ratchet" basis: the rating thresholds are periodically tightened so that the star bands continue to signal genuinely superior efficiency rather than drifting upward as technology improves. The previous star rating plan for water heaters ran for the validity window of 1 January 2023 to 31 December 2025; from 1 January 2023 the 1-Star permission for units up to 200 litres rated capacity was already withdrawn as a minimum-performance upgrade. The current revision continues that trajectory into the next plan period.

Technical scope

The star rating for stationary storage type electric water heaters is determined by standing loss, the energy consumed by a full water heater, after steady state conditions are reached, when no water is drawn over 24 hours, measured at a 45°C temperature difference (kWh/24h/45°C). Lower standing loss earns a higher star rating. The scheme covers single-phase electric storage water heaters for household and similar purposes, in both horizontal and vertical configurations, up to a rated capacity of 200 litres.

Under the revised table, the standing loss limits for each star band are tightened, so existing designs that previously sat comfortably within a higher band may drop a level unless re-tested and re-registered against the new norms.

What This Means for Manufacturers

• Ratings do not carry over automatically. A model rated under the 2023–2025 table cannot rely on that rating once the revised table takes effect. Re-registration against the new standing-loss thresholds is required to retain market access.

• Re-testing is likely. Because the qualifying standing-loss limits move, manufacturers should expect to submit fresh test reports from NABL-accredited laboratories to substantiate the star claim under the revised table.

• Label artwork must be updated. Star labels reflect the validity period; products carrying labels tied to the expired window will need updated labels showing the current validity period.

• Importers carry the same obligation. The registration and labelling duty falls on the manufacturer or importer placing the product on the Indian market — imported geysers are not exempt.

• Plan for portfolio impact. Models near a band boundary are most exposed; a model marketed as a higher-star product may need a design or insulation change to hold its position under the tighter limits.

  
  

Certification Impact Summary

Area	Before (2023–2025 plan)	After (revised plan)
Star rating table	Standing-loss limits per 2023–2025 table (Table 3.4)	Revised, tighter standing-loss limits per the new table
Label validity period	1 Jan 2023 – 31 Dec 2025	New plan period (aligned with BEE's 1 Jan 2026 – 31 Dec 2028 cycle — confirm exact dates in the Geyser advisory)
Existing registrations	Valid through 31 Dec 2025	Must be re-registered under the revised table to remain valid
Test reports	Existing NABL reports	Fresh NABL-accredited test reports likely required against new limits
Star achievable	Per old thresholds	Same model may drop a band unless improved/re-tested
Market access	Maintained under old label	Conditional on re-registration and updated label
Governing references	IS 2082 · Schedule 10 · S.O. 2902(E), 7 Sep 2016	Same standards; revised star rating table

Timeline + Required Actions

1. Confirm the new validity window. Verify the precise start/end dates of the revised plan against the BEE Geyser advisory note (GeyserNote.pdf). BEE's broader 2026 cycle uses a 1 January 2026 – 31 December 2028 validity period across appliance categories.

2. Audit your registered portfolio. Identify every active SKU registered under the 2023–2025 table and check each model's standing loss against the revised limits.

3. Schedule re-testing. Book NABL-accredited testing for any model that needs fresh standing-loss data to substantiate its star claim under the new table.

4. Re-register affected models. Submit applications under the revised norms via the BEE Standards & Labelling portal within the deadline stated in the Geyser advisory.

5. Update label artwork. Replace existing labels with versions reflecting the revised star rating and the new validity period.

6. Sequence production and stock. Align manufacturing and inventory so that product placed on the market after the cut-over carries compliant, revised-period labels; clear or re-label old-period stock as required.

   
   

Market Significance

The revision reinforces a consistent direction of travel in India's energy efficiency regime: periodic tightening of star thresholds to keep the label meaningful and to push manufacturers toward more efficient designs. For the water heater category a high volume, mandatory labelled product, the change is less a one-off event than a recurring compliance checkpoint that rewards manufacturers who plan re-registration ahead of the validity cut-over and penalises those who let labels lapse with delisting and lost shelf presence
