Smarter immersion water heater control
The E7+ is a smart-capable wireless immersion heater controller that gives households precise, flexible control over their hot water. It works with a wide variety of electricity tariffs, including off-peak, and the optional user app works locally via Bluetooth, with the option to upgrade to Wi-Fi
For households using electric immersion heaters, managing hot water efficiently has long been a challenge. Traditional immersion heater controllers are rigid and manual, tied to fixed schedules that cannot adapt to changing routines, off-peak tariff windows, or varying household demand. Heating a full tank unnecessarily or running at peak-rate times because of a lack of flexible control directly increases electricity bills. At the same time, the shift toward time-of-use tariffs and off-peak electricity pricing means the opportunity to save money through smarter scheduling is significant, but only if the controller can take advantage of it.
The E7+ solves this by combining a full 7-day programmer with Bluetooth app control and an optional Wi-Fi adaptor for complete remote management from anywhere, no hub or gateway required. A manual boost button provides instant top-up for 30 minutes, 1, or 2 hours without disrupting the set programme, and the app measures estimated energy consumed during boost and off-peak periods in kWh, giving households real visibility of their usage. A tamper-proof programme security feature makes it particularly well-suited to rental properties.
takes the complexity out of hot water management, helping households make the most of off-peak tariffs and reduce costs.
The 7-day programmer helps schedule hot water heating around cheaper electricity periods, making it easier to use off-peak and time-of-use tariffs.
Bluetooth app control provides local hot water management without Wi-Fi, while an optional plug-in Wi-Fi adaptor enables remote access from anywhere.
A manual boost button provides 30-minute, 1-hour, or 2-hour hot water top-ups without changing the programmed schedule.
The supplied adaptor plate lets you retrofit the E7+ onto existing Economy 7 controllers.
The tamper-proof programme security feature helps prevent unauthorised changes to heating schedules, making the controller suitable for rental and landlord-managed properties.
The app measures estimated energy consumed during boost and off-peak periods in kWh, giving households greater visibility into their hot water usage.
The E7+ suits the UK residential market, not just households on off-peak electricity tariffs. This also includes landlords managing properties with electric hot water systems, and social housing providers looking to help residents reduce energy costs. As time-of-use tariffs become more prevalent and pressure on household energy budgets continues, the ability to programme hot water heating around cheaper electricity periods offers a straightforward, accessible route to meaningful savings.
