There are 3 ways that we could minimize the frequency of re-boil
1. Set a lower “Keep Warm” temperature. The higher the temperature you set, the more frequent will be the re-boil in order to keep the water temperature. Therefore, set a lower temperature can help minimize the re-boil.
2. Use the “Energy Mode”. After leaving the water boiler and warmer not in use for 2 hours, the set temperature will automatically decease 5℃ and keep warm.
3. Use water boiler and warmer with VE function. The vacuum layer of the VE products is the same as the vacuum layer of the thermal bottles. It can help keep warm for a certain period of time without using power.
