matchar Posted October 17, 2022 Share Posted October 17, 2022 I'm curious about these egat energy labels as I was comparing two Samsung refrigerators (both of them digital inverters). If I'm reading the labels correctly; it seems like the smaller fridge uses more electricity and yet it has a 2 star rating...but the bigger fridge uses less energy and only has a 0 star rating?

MJCM Posted October 17, 2022 Share Posted October 17, 2022 That 2nd picture is not 0 but it has a 5 star rating. That Thai written says number 5! 1 Link to comment Share on other sites More sharing options...

Yes they both have level 5 rating (as nearly all modern appliances do) but there is also a new sub rating between 1 and 3 stars which is indicated at the top. 1 Link to comment Share on other sites More sharing options...

That New Sub rating as you say is even on our 3 year old Fridge. IMHO those 1,2,3 stars are LOW ratings and the best you can get is the Number 5 Rating (yellow sticker with Number 5 in Thai written on it) And please do know the numbers written on it, kWh usage per year and THB per year are just an indication and could fluctuate, for example on our fridge it says 477.06 kWh usage per year, but it's closer to 600. (approx 2 kW per day) Edit: If you want a Fridge that is efficient with Electricity buy an Inverter Edited October 18, 2022 by MJCM 1 Link to comment Share on other sites More sharing options...

KhunBENQ Posted October 18, 2022 Share Posted October 18, 2022 (edited) Forget the stars, make your own???? Second one has bigger volume (258 liter vs 208 liter) and less power consumption. Just do math: volume/power consumption. The higher the number the better. For the second one: 258.5/269 = 0.96 First: 208/369 = 0.56 Much worse. Rule of thumb Volume in liters equals power consumption per year: very good one. Edited October 18, 2022 by KhunBENQ 258.5 1 Link to comment Share on other sites More sharing options...

matchar Posted October 18, 2022 Author Share Posted October 18, 2022 I believe the best rating is a level 5 with 3 stars. 1 Link to comment Share on other sites More sharing options...

I have no idea why they use this visualization. As far as I remember in the past it was simply like a clockwise meter (1-2-3-4-5).

Yes the old labels don't have stars and nearly every product received a level 5 rating so it was difficult for consumers to compare between them. Hence the new labels were introduced with 0-3 stars above the level 5 but clearly something went wrong as the fridge with 2 stars is worse than the fridge with 0 stars.

Popular Post unheard Posted October 18, 2022 Popular Post Share Posted October 18, 2022 (edited) @matchar You're reading the labels correctly. The problem is with the labels - somehow they've managed to print the second one with an incorrect star rating. At the egat's own site both models carry the same efficiency rating - 5★★ The energy consumption numbers are also messed up as printed on the labels.

Thanks for the clarification, I wonder who prints these labels. Probably a good idea to check the figures match on the EGAT website before making any future purchases.

And yes, not a bad idea to spend a few minutes to verify the label numbers against the database at the egat's website: http://labelno5.egat.co.th/new58/?taxonomy=language&term=en Edited October 18, 2022 by unheard 1 Link to comment Share on other sites More sharing options...

Technical progress. Same reclassification in the EU. It was almost all "A++" (A to D?). Now not many come above "F" I am not a EU fan but this is surely better visualized then here.
