Top-Up Heating: Instead of heating the entire tank, Mixergy’s top-up technology allows you to heat only the portion of water you need, saving time and reducing energy consumption.
-
Intelligent Control: Equipped with smart technology, the Mixergy cylinder can be controlled remotely via a mobile app, allowing users to schedule heating times and monitor water levels and usage.
-
Renewable Energy Ready: It works with solar PV, heat pumps, and off-peak electricity, making it ideal for eco-conscious households and users seeking to lower carbon emissions.
-
Optimized for Heat Pumps: The Mixergy cylinder can be set to operate at lower temperatures, which aligns well with heat pumps’ lower output temperatures, ensuring energy efficiency.
-
Learning Algorithms: Over time, the system learns usage patterns and optimizes its heating schedule, helping to further reduce energy costs.
-
25 year guarantee: the Mixergy X is ready for whatever the future holds.
Savings
Mixergy only heats the water you need rather than the whole tank, reducing energy waste and cutting heating bills.
How it works
