Mixergy X
Intelligent hot water storage for any build type
The cylinder that delivers faster reheat, lower running costs, and futureproof performance for social housing, new build, and commercial projects.
Mixergy X integrates smart controls and futureproof compatibility with any heat source to simplify compliance and enhance building efficiency.
A smart cylinder that’s ahead of the curve
The Mixergy X transforms traditional hot water systems into intelligent, energy-saving assets.
Works with gas, electric, or heat pump systems.
Heats only what’s needed for faster delivery and reduced waste.
Enhances heat pump performance and overall system efficiency.
Designed for every application, from homes and apartments to hotels, offices, and stadiums.
1,000 Smart Cylinders Powering Birmingham’s Net Zero Plan
Birmingham City Council installed over 1,000 Mixergy X cylinders to cut emissions and tenant energy costs, achieving £286,000 in savings and removing 172 tonnes of CO₂ in just two years.
We need to reduce our carbon outputs and focus on fuel poverty. Mixergy is an ideal solution to address both challenges.

Mixergy X FAQ
What makes Mixergy X different from a traditional cylinder?
Mixergy X uses patented top-down heating technology that heats only the water required, cutting energy use by up to 40 percent and delivering hot water up to 10 times faster than standard systems. This improves energy performance ratings and reduces operating costs across property portfolios.
Is Mixergy X compatible with all heating systems?
Yes. Mixergy X integrates with gas, direct electric, solar PV, and heat pump systems. Its universal design allows it to be specified for retrofit programmes, new-build schemes, and commercial buildings alike.
Does Mixergy X connect to the Mixergy IO platform?
Every Mixergy X cylinder connects to the Mixergy IO dashboard, enabling real-time monitoring, machine-learning optimisation, and centralised control. This provides housing providers, developers, and estate managers with complete visibility of system performance.
How does Mixergy X improve SAP and EPC outcomes?
The cylinder is recognised within SAP 10.2 and the Home Energy Model. Its smart controls, stratified heating, and energy efficiency contribute measurable uplifts in SAP ratings, helping developers meet compliance targets and improve EPC scores without additional solar hardware.
Can Mixergy X support grid flexibility and smart-tariff optimisation?
Yes. Mixergy X supports demand-side response participation, automatically adjusting heating schedules to off-peak periods. This reduces grid load and enables participation in flexibility schemes for long-term cost savings.
Is Mixergy X suitable for commercial applications?
Yes. Mixergy X is available in larger commercial capacities and integrates with building management systems via Modbus TCP. It provides high-efficiency, BMS-connected hot water storage for hotels, offices, healthcare, and mixed-use estates.
Does Mixergy X require specialist installation or maintenance?
Mixergy X installs like a standard unvented cylinder and requires no specialist commissioning. Modular smart components simplify servicing, and software updates are delivered remotely via Mixergy iO, reducing maintenance visits and lifecycle costs.
