Backed by a 7-year warranty, it’s designed for seamless integration and efficient hot water management.

## Description

The new E7+ from Secure is the latest version of the Electronic 7 hot water programmer. 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 to make retrofitting a simple matter of plug and play. The E7+ can be controlled by the Secure Bluetooth-enabled App, within a property, and there is even an optional plugin Wi-Fi card that will turn the E7+ into a truly smart unit you can control from anywhere. E7+ smart immersion heater timer is designed to control one or two 3kW immersion heaters, can also be programmed locally to provide a full tank of hot water whenever required during off-peak electricity timing. Each heater can be programmed separately for maximum energy saving and control. The E7+ is perfect for standalone control of electric hot water and uses the same app as our range of smart-capable programmable thermostats - C1727 and H3747.
