Mixergy

Connected hot-water cylinders

Mixergy designs intelligent hot-water cylinders that heat stored water in a controlled way and connect to apps and energy systems. The company describes the cylinder as a thermal battery that can store energy as hot water and respond to a building's needs. Its product range includes Mixergy X, Solar X, iHP X and Cube X, aimed at different installations and property types. Product literature provides dimensions, installation requirements, controls and compatibility information for each cylinder.

Products for homes and building projects

The company presents solutions for new-build homes, social housing, retrofit projects and commercial estates. Solar X is described as a solar-PV-compatible cylinder; iHP X combines an indoor heat-pump cylinder with direct electric heating; Cube X is a compact unit for space-constrained and social-housing retrofit settings. Mixergy X is positioned as a flexible hot-water product for different energy systems. Designers and buyers can use the product datasheets and specification tools to compare options for a specific project.

Apps, dashboards and grid flexibility

Mixergy provides apps and dashboards for viewing and controlling hot-water systems, and offers Mixergy Flex for participation in grid-flexibility services. The platform aims to coordinate when water is heated and provide visibility into energy use. The company also publishes SAP and RdSAP resources for modelling and compliance work. Participation, controls, supported tariffs and potential payments depend on system configuration, eligibility and the service terms available to a household or project.

Support for housing providers and commercial sites

For social housing, Mixergy promotes smart cylinders and connected controls for tenant energy use, maintenance and compliance. For new builds, its materials discuss SAP modelling and alignment with the Future Homes Standard. Commercial solutions are described as scalable and capable of integration with building-management systems. The website includes case studies, installation support, manuals, datasheets, homeowner and resident help, and contact details for projects and technical questions.
