Our Electrisaver® electronic boost control is a simple push button electronic timer that saves energy by remembering to switch off. Our electronic boost controls are used for immersion heater control, heated mirrors, panel heaters, and in towel rails. Our water heating boost control always gives priority to the off-peak supply.
