Safe Island is an instant electric water heater designed for the Southeast Asian market. It revolutionizes the traditional method of installing a water heater with quick connectors that replaces the screwing method. The color of each quick connector is clear, which makes it easier, more professional, and safer for users to install it. The design reconfigures the layout of the internal structure, separating the junction box part of the machine that needs to be opened for installation. Because it is used in the bathroom, the rubber ring of the top shell and the internal translucent shell endow the product with better waterproof performance.
