Electric Instant Water Heater with Vacuum Bottle Structure
The entire tank of the electric instant water heater is covered with a vacuum jacket (double-walled, vacuum structure) to effectively retain heat. The structure contributes to saving energy.
Development background
Tiger Corporation co-developed an electric Instant Water Heater with TOTO Ltd. The electric instant water heater was designed to be installed in a washstand. The tank is covered with a stainless steel vacuum jacket to increase the heat-retaining performance. This helps reduce the energy required to retain heat, achieving eco-friendliness. The vacuum jacket also serves as the exterior, making the product compact.
Product details
A one-second supply of warmed water kept in tank is convenient for customers. The compact design does not take up more storage space (pull-out type) .
