BEE (Bureau of Energy Efficiency) is the governing body that mandates the display of star ratings on appliances so that consumers know how much electricity that particular appliance will consume.
Water heaters also come under the mandatory appliance list for BEE to show the star rating. However, it is only applicable to storage water heaters that have a capacity of 6 liters or more.
The BEE star rating does not apply to instant water heaters as they do not have water tanks.
Let’s learn more about BEE Star Ratings For Water Heaters and how they affect the power consumption of water heaters.
BEE Star Ratings Of Water Heaters
BEE Star Rating for Water Heaters is based on the standing loss. The more the standing loss, the more the power consumption, and the lower the star rating.
BEE Star Ratings for Water Heaters are also based on the assumption that the standing loss will be calculated considering water temperature at 45°C for a 24-hour duration.
Here is the latest data for the standing loss for water heaters to qualify for different star ratings. BEE mandates that all water heaters with a capacity of 6 liters to 200 liters should show the star rating sticker on their appliance.
