Our smart-capable immersion heater control

The new E7+ from Secure is the latest version of the Electronic 7 water heater controller. E7+ is designed to control one or two 3kW immersion heaters. It can also be programmed locally to provide a full tank of hot water whenever required during off-peak electricity periods. Each heater can be programmed separately for maximum energy saving and control. Designed to be the successor to both the Electronic 7 and the Economy 7 Quartz, it is easy to install or retrofit. Now with a new compact interface that is perfect for newer installations, as well as an adaptor plate, which allows fresh installations to be more ergonomic and streamlined, whilst still making the E7+ a plug-in replacement for all the existing legacy water heaters from Horstmann. The E7+ can be controlled by the Secure Bluetooth-enabled app, within a property, and there is an optional plugin Wi-Fi adaptor that will turn the E7+ into a truly smart unit you can control from anywhere. This app is also used by our range of smart-capable programmable thermostats - C1727 and H3747.
