Programmable boost - can be programmed so that it will heat only a small part of your tank at a set time each day

The new E7+ from Secure is the latest version of the Electronic 7 hot water programmer. E7+ is designed to control one or two 3kW immersion heaters, utilising off-peak electricity tariffs to provide a full tank of hot water whenever required. Each heater can be programmed separately for maximum energy saving and control. Direct replacement using existing wall-box for Economy 7 Quartz, Electronic 7, Electronic 7L & Maxistore Electronic 7 can be used with single, dual or twin element immersion heaters and allows for up to three secure off-peak heating periods every 24 hours, making maximum use of electricity when tariffs are cheaper.

Among the Electronic 7’s range of features is its full compatibility with all utility tariffs and, unlike some controls, it is not restricted by cumbersome tariff menu’s. Off peak settings are programmed using simple step-by-step on screen programming and coupled with its plug-in and replace installation, the unit has ease of use features for the installer and user alike.

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. And, as some utility tariffs offer additional cheaper electricity periods during the day time, the Electronic 7 has extra off peak switching periods available to accommodate these. The control retains the 1 hour boost button that permits the householder to activate a short term override of the set programme or, if it is known that extra hot water will be required every day, the ‘boost’ element (in the cylinder) can be programmed so that it will heat only a small part of the tank. This is normally the upper immersion heater element and can be programmed to come on once each day at a set time.
